Environments and deployments (FREE)
Environments describe where code is deployed.
Each time GitLab CI/CD deploys a version of code to an environment, a deployment is created.
GitLab:
- Provides a full history of deployments to each environment.
- Tracks your deployments, so you always know what is deployed on your servers.
If you have a deployment service like Kubernetes associated with your project, you can use it to assist with your deployments.
View environments and deployments
Prerequisites:
- You must have at least the Reporter role.
There are a few ways to view a list of environments for a given project:
-
On the project's overview page, if at least one environment is available (that is, not stopped).
-
On the left sidebar, select Deployments > Environments. The environments are displayed.
-
To view a list of deployments for an environment, select the environment name, for example,
staging
.
Deployments show up in this list only after a deployment job has created them.
Search environments
- Introduced in GitLab 15.5.
- Searching environments within a folder was introduced in GitLab 15.7 with Feature flag
enable_environments_search_within_folder
. Enabled by default.
To search environments by name:
- On the top bar, select Main menu > Projects and find your project.
- On the left sidebar, select Deployments > Environments.
- In the search bar, enter your search term.
- The length of your search term should be 3 or more characters.
- Matching applies from the beginning of the environment name.
- For example,
devel
matches the environment namedevelopment
, butelop
does not.
- For example,
- For environments with a folder name format, matching applies after the base folder name.
- For example when the name is
review/test-app
, search termtest
matchesreview/test-app
. - Also searching with the folder name prefixed like
review/test
matchesreview/test-app
.
- For example when the name is
Types of environments
An environment is either static or dynamic:
- Static environment
- Usually reused by successive deployments.
- Has a static name - for example,
staging
orproduction
. - Created manually or as part of a CI/CD pipeline.
- Dynamic environment
- Usually created in a CI/CD pipeline and used by only a single deployment, then either stopped or deleted.
- Has a dynamic name, usually based on the value of a CI/CD variable.
- A feature of review apps.
Create a static environment
You can create a static environment in the UI or in your .gitlab-ci.yml
file.
In the UI
Prerequisites:
- You must have at least the Developer role.
To create a static environment in the UI:
- On the top bar, select Main menu > Projects and find your project.
- On the left sidebar, select Deployments > Environments.
- Select New environment.
- Complete the fields.
- Select Save.
.gitlab-ci.yml
file
In your Prerequisites:
- You must have at least the Developer role.
To create a static environment, in your .gitlab-ci.yml
file:
- Define a job in the
deploy
stage. - In the job, define the environment
name
andurl
. If an environment of that name doesn't exist when the pipeline runs, it is created.
NOTE:
Some characters cannot be used in environment names. For more information about the
environment
keywords, see the .gitlab-ci.yml
keyword reference.
For example, to create an environment named staging
, with URL https://staging.example.com
:
deploy_staging:
stage: deploy
script:
- echo "Deploy to staging server"
environment:
name: staging
url: https://staging.example.com
Create a dynamic environment
To create a dynamic environment, you use CI/CD variables that are unique to each pipeline.
Prerequisites:
- You must have at least the Developer role.
To create a dynamic environment, in your .gitlab-ci.yml
file:
- Define a job in the
deploy
stage. - In the job, define the following environment attributes:
-
name
: Use a related CI/CD variable like$CI_COMMIT_REF_SLUG
. Optionally, add a static prefix to the environment's name, which groups in the UI all environments with the same prefix. -
url
: Optional. Prefix the hostname with a related CI/CD variable like$CI_ENVIRONMENT_SLUG
.
-
NOTE:
Some characters cannot be used in environment names. For more information about the
environment
keywords, see the .gitlab-ci.yml
keyword reference.
In the following example, every time the deploy_review_app
job runs the environment's name and
URL are defined using unique values.
deploy_review_app:
stage: deploy
script: make deploy
environment:
name: review/$CI_COMMIT_REF_SLUG
url: https://$CI_ENVIRONMENT_SLUG.example.com
only:
- branches
except:
- main
Rename an environment
- Renaming an environment by using the UI was removed in GitLab 14.3.
- Renaming an environment by using the API was deprecated in GitLab 15.9 and is planned for removal in GitLab 16.0.
You cannot rename an environment by using the UI, and the API method was deprecated in GitLab 15.9.
To achieve the same result as renaming an environment:
- Stop the existing environment.
- Delete the existing environment.
- Create a new environment with the desired name.
Deployment tier of environments
Introduced in GitLab 13.10.
Sometimes, instead of using an industry standard
environment name, like production
, you might want to use a code name, like customer-portal
.
While there is no technical reason not to use a name like customer-portal
, the name
no longer indicates that the environment is used for production.
To indicate that a specific environment is for a specific use, you can use tiers:
Environment tier | Environment name examples |
---|---|
production |
Production, Live |
staging |
Staging, Model, Demo |
testing |
Test, QC |
development |
Dev, Review apps, Trunk |
other |
By default, GitLab assumes a tier based on the environment name.
Instead, you can use the deployment_tier
keyword to specify a tier.
Configure manual deployments
You can create a job that requires someone to manually start the deployment. For example:
deploy_prod:
stage: deploy
script:
- echo "Deploy to production server"
environment:
name: production
url: https://example.com
rules:
- if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH
when: manual
The when: manual
action:
- Exposes a play button for the job in the GitLab UI, with the text Can be manually deployed to <environment>.
- Means the
deploy_prod
job is only triggered when the play button is selected.
You can find the play button in the pipelines, environments, deployments, and jobs views.
Configure Kubernetes deployments (deprecated)
- Introduced in GitLab 12.6.
- Deprecated in GitLab 14.5.
WARNING: This feature was deprecated in GitLab 14.5.
If you are deploying to a Kubernetes cluster
associated with your project, you can configure these deployments from your
.gitlab-ci.yml
file.
NOTE: Kubernetes configuration isn't supported for Kubernetes clusters managed by GitLab.
The following configuration options are supported:
In the following example, the job deploys your application to the
production
Kubernetes namespace.
deploy:
stage: deploy
script:
- echo "Deploy to production server"
environment:
name: production
url: https://example.com
kubernetes:
namespace: production
rules:
- if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH
When you use the GitLab Kubernetes integration to deploy to a Kubernetes cluster, you can view cluster and namespace information. On the deployment job page, it's displayed above the job trace:
Configure incremental rollouts
Learn how to release production changes to only a portion of your Kubernetes pods with incremental rollouts.
CI/CD variables for environments and deployments
When you create an environment, you specify the name and URL.
If you want to use the name or URL in another job, you can use:
-
$CI_ENVIRONMENT_NAME
. The name defined in the.gitlab-ci.yml
file. -
$CI_ENVIRONMENT_SLUG
. A "cleaned-up" version of the name, suitable for use in URL and DNS, for example. This variable is guaranteed to be unique. -
$CI_ENVIRONMENT_URL
. The environment's URL, which was specified in the.gitlab-ci.yml
file or automatically assigned.
If you change the name of an existing environment, the:
-
$CI_ENVIRONMENT_NAME
variable is updated with the new environment name. -
$CI_ENVIRONMENT_SLUG
variable remains unchanged to prevent unintended side effects.
Set dynamic environment URLs after a job finishes
Introduced in GitLab 12.9.
In a job script, you can specify a static environment URL.
However, there may be times when you want a dynamic URL. For example,
if you deploy a Review App to an external hosting
service that generates a random URL per deployment, like https://94dd65b.amazonaws.com/qa-lambda-1234567
.
In this case, you don't know the URL before the deployment script finishes.
If you want to use the environment URL in GitLab, you would have to update it manually.
To address this problem, you can configure a deployment job to report back a set of
variables. These variables include the URL that was dynamically-generated by the external service.
GitLab supports the dotenv (.env
) file format,
and expands the environment:url
value with variables defined in the .env
file.
To use this feature, specify the
artifacts:reports:dotenv
keyword in .gitlab-ci.yml
.
For an overview, see Set dynamic URLs after a job finished.
Example of setting dynamic environment URLs
The following example shows a Review App that creates a new environment
for each merge request. The review
job is triggered by every push, and
creates or updates an environment named review/your-branch-name
.
The environment URL is set to $DYNAMIC_ENVIRONMENT_URL
:
review:
script:
- DYNAMIC_ENVIRONMENT_URL=$(deploy-script) # In script, get the environment URL.
- echo "DYNAMIC_ENVIRONMENT_URL=$DYNAMIC_ENVIRONMENT_URL" >> deploy.env # Add the value to a dotenv file.
artifacts:
reports:
dotenv: deploy.env # Report back dotenv file to rails.
environment:
name: review/$CI_COMMIT_REF_SLUG
url: $DYNAMIC_ENVIRONMENT_URL # and set the variable produced in script to `environment:url`
on_stop: stop_review
stop_review:
script:
- ./teardown-environment
when: manual
environment:
name: review/$CI_COMMIT_REF_SLUG
action: stop
As soon as the review
job finishes, GitLab updates the review/your-branch-name
environment's URL.
It parses the deploy.env
report artifact, registers a list of variables as runtime-created,
uses it for expanding environment:url: $DYNAMIC_ENVIRONMENT_URL
and sets it to the environment URL.
You can also specify a static part of the URL at environment:url
, such as
https://$DYNAMIC_ENVIRONMENT_URL
. If the value of DYNAMIC_ENVIRONMENT_URL
is
example.com
, the final result is https://example.com
.
The assigned URL for the review/your-branch-name
environment is visible in the UI.
Note the following:
-
stop_review
doesn't generate a dotenv report artifact, so it doesn't recognize theDYNAMIC_ENVIRONMENT_URL
environment variable. Therefore you shouldn't setenvironment:url
in thestop_review
job. - If the environment URL isn't valid (for example, the URL is malformed), the system doesn't update the environment URL.
- If the script that runs in
stop_review
exists only in your repository and therefore can't useGIT_STRATEGY: none
, configure merge request pipelines for these jobs. This ensures that runners can fetch the repository even after a feature branch is deleted. For more information, see Ref Specs for Runners.
NOTE:
For Windows runners, using echo
to write to .env
files may fail. Using the PowerShell Add-Content
command
helps in such cases. For example:
Add-Content -Path deploy.env -Value "DYNAMIC_ENVIRONMENT_URL=$DYNAMIC_ENVIRONMENT_URL"
Track newly included merge requests per deployment
GitLab can track newly included merge requests per deployment. When a deployment succeeded, the system calculates commit-diffs between the latest deployment and the previous deployment. This tracking information can be fetched via the Deployment API and displayed at a post-merge pipeline in merge request pages.
To activate this tracking, your environment must be configured in the following:
-
Environment name is not using folders with
/
(that is, top-level/long-lived environments), OR -
Environment tier is either
production
orstaging
.
Here are the example setups of environment
keyword in .gitlab-ci.yml
:
# Trackable
environment: production
environment: production/aws
environment: development
# Non Trackable
environment: review/$CI_COMMIT_REF_SLUG
environment: testing/aws
Working with environments
Once environments are configured, GitLab provides many features for working with them, as documented below.
Environment rollback
When you roll back a deployment on a specific commit, a new deployment is created. This deployment has its own unique job ID. It points to the commit you're rolling back to.
For the rollback to succeed, the deployment process must be defined in
the job's script
.
Retry or roll back a deployment
If there is a problem with a deployment, you can retry it or roll it back.
To retry or rollback a deployment:
- On the top bar, select Main menu > Projects and find your project.
- On the left sidebar, select Deployments > Environments.
- Select the environment.
- To the right of the deployment name:
- To retry a deployment, select Re-deploy to environment.
- To roll back to a deployment, next to a previously successful deployment, select Rollback environment.
NOTE: If you have prevented outdated deployment jobs in your project, the rollback buttons might be hidden or disabled. In this case, see how to rollback to an outdated deployment.
Environment URL
- Fixed to persist arbitrary URLs in GitLab 15.2 with a flag named
soft_validation_on_external_url
. Disabled by default.- Generally available in GitLab 15.3. Feature flag
soft_validation_on_external_url
removed.
The environment URL is displayed in a few places in GitLab:
- In a merge request as a link:
- In the Environments view as a button:
- In the Deployments view as a button:
You can see this information in a merge request if:
- The merge request is eventually merged to the default branch (usually
main
). - That branch also deploys to an environment (for example,
staging
orproduction
).
For example:
Go from source files to public pages
With GitLab Route Maps, you can go directly from source files to public pages in the environment set for Review Apps.
Stopping an environment
Stopping an environment means its deployments are not accessible on the target server. You must stop an environment before it can be deleted.
If the environment has an on_stop
action defined, it's
executed to stop the environment.
Stop an environment when a branch is deleted
You can configure environments to stop when a branch is deleted.
In the following example, a deploy_review
job calls a stop_review
job to clean up and stop the
environment.
- Both jobs must have the same
rules
oronly/except
configuration. Otherwise, thestop_review
job might not be included in all pipelines that include thedeploy_review
job, and you cannot triggeraction: stop
to stop the environment automatically. - The job with
action: stop
might not run if it's in a later stage than the job that started the environment. - If you can't use merge request pipelines,
set the
GIT_STRATEGY
tonone
in thestop_review
job. Then the runner doesn't try to check out the code after the branch is deleted.
deploy_review:
stage: deploy
script:
- echo "Deploy a review app"
environment:
name: review/$CI_COMMIT_REF_SLUG
url: https://$CI_ENVIRONMENT_SLUG.example.com
on_stop: stop_review
stop_review:
stage: deploy
script:
- echo "Remove review app"
environment:
name: review/$CI_COMMIT_REF_SLUG
action: stop
when: manual
Stop an environment when a merge request is merged or closed
When you use the merge request pipelines configuration,
the stop
trigger is automatically enabled.
In the following example, the deploy_review
job calls a stop_review
job to clean up and stop
the environment.
deploy_review:
stage: deploy
script:
- echo "Deploy a review app"
environment:
name: review/$CI_COMMIT_REF_SLUG
on_stop: stop_review
rules:
- if: $CI_MERGE_REQUEST_ID
stop_review:
stage: deploy
script:
- echo "Remove review app"
environment:
name: review/$CI_COMMIT_REF_SLUG
action: stop
rules:
- if: $CI_MERGE_REQUEST_ID
when: manual
Run a pipeline job when environment is stopped
You can specify a job to run when an environment is stopped.
Prerequisites:
- Both jobs must have the same rules or only/except configuration.
- The
stop_review_app
job must have the following keywords defined:-
when
, defined at either:- The job level.
-
In a rules clause. If you use
rules
andwhen: manual
, you should also setallow_failure: true
so the pipeline can complete even if the job doesn't run.
environment:name
environment:action
-
In your .gitlab-ci.yml
file, specify in the on_stop
keyword the name of the job that stops the environment.
In the following example:
- A
review_app
job calls astop_review_app
job after the first job is finished. - The
stop_review_app
is triggered based on what is defined underwhen
. In this case, it is set tomanual
, so it needs a manual action from the GitLab UI to run. - The
GIT_STRATEGY
is set tonone
. If thestop_review_app
job is automatically triggered, the runner doesn't try to check out the code after the branch is deleted.
review_app:
stage: deploy
script: make deploy-app
environment:
name: review/$CI_COMMIT_REF_SLUG
url: https://$CI_ENVIRONMENT_SLUG.example.com
on_stop: stop_review_app
stop_review_app:
stage: deploy
variables:
GIT_STRATEGY: none
script: make delete-app
when: manual
environment:
name: review/$CI_COMMIT_REF_SLUG
action: stop
Stop an environment after a certain time period
You can set an environment to stop automatically after a certain time period.
NOTE: Due to resource limitations, a background worker for stopping environments runs only once every hour. This means that environments may not be stopped after the exact time period specified, but are instead stopped when the background worker detects expired environments.
In your .gitlab-ci.yml
file, specify the environment:auto_stop_in
keyword. Specify the time period in natural language, such as 1 hour and 30 minutes
or 1 day
.
After the time period passes, GitLab automatically triggers a job to stop the environment.
In the following example:
- Each commit on a merge request triggers a
review_app
job that deploys the latest change to the environment and resets its expiry period. - If the environment is inactive for more than a week, GitLab automatically triggers the
stop_review_app
job to stop the environment.
review_app:
script: deploy-review-app
environment:
name: review/$CI_COMMIT_REF_SLUG
on_stop: stop_review_app
auto_stop_in: 1 week
rules:
- if: $CI_MERGE_REQUEST_ID
stop_review_app:
script: stop-review-app
environment:
name: review/$CI_COMMIT_REF_SLUG
action: stop
rules:
- if: $CI_MERGE_REQUEST_ID
when: manual
View an environment's scheduled stop date and time
When a environment has been scheduled to stop after a specified time period, you can view its expiration date and time.
To view an environment's expiration date and time:
- On the top bar, select Main menu > Projects and find your project.
- On the left sidebar, select Deployments > Environments.
- Select the name of the environment.
The expiration date and time is displayed in the upper-left corner, next to the environment's name.
Override a environment's scheduled stop date and time
When a environment has been scheduled to stop after a specified time period, you can override its expiration.
To override an environment's expiration:
- On the top bar, select Main menu > Projects and find your project.
- On the left sidebar, select Deployments > Environments.
- Select the deployment name.
- in the upper-right corner, select the thumbtack ({thumbtack}).
The auto_stop_in
setting is overridden and the environment remains active until it's stopped
manually.
on_stop
action
Stop an environment without running the There may be times when you want to stop an environment without running the defined
on_stop
action. For example, you want to delete many
environments without using CI/CD minutes.
To stop an environment without running the defined on_stop
action, execute the
Stop an environment API with the parameter
force=true
.
Stop an environment by using the UI
NOTE:
To trigger an on_stop
action and manually stop an environment from the
Environments view, the stop and deploy jobs must be in the same
resource_group
.
To stop an environment in the GitLab UI:
- On the top bar, select Main menu > Projects and find your project.
- On the left sidebar, select Deployments > Environments.
- Next to the environment you want to stop, select Stop.
- On the confirmation dialog box, select Stop environment.
Multiple stop actions for an environment
- Introduced in GitLab 14.10 with a flag named
environment_multiple_stop_actions
. Disabled by default.- Generally available in GitLab 15.0. Feature flag
environment_multiple_stop_actions
removed.
To configure multiple parallel stop actions on an environment, specify the
on_stop
keyword across multiple
deployment jobs for the same environment
, as defined in the
.gitlab-ci.yml
file.
When an environment is stopped, the matching on_stop
actions from only successful deployment jobs are run in parallel, in no particular order.
In the following example, for the test
environment there are two deployment jobs:
deploy-to-cloud-a
deploy-to-cloud-b
When the environment is stopped, the system runs on_stop
actions teardown-cloud-a
and
teardown-cloud-b
in parallel.
deploy-to-cloud-a:
script: echo "Deploy to cloud a"
environment:
name: test
on_stop: teardown-cloud-a
deploy-to-cloud-b:
script: echo "Deploy to cloud b"
environment:
name: test
on_stop: teardown-cloud-b
teardown-cloud-a:
script: echo "Delete the resources in cloud a"
environment:
name: test
action: stop
when: manual
teardown-cloud-b:
script: echo "Delete the resources in cloud b"
environment:
name: test
action: stop
when: manual
Delete an environment
Delete an environment when you want to remove it and all its deployments.
Prerequisites:
- You must have at least the Developer role.
- You must stop the environment before it can be deleted.
To delete an environment:
- On the top bar, select Main menu > Projects and find your project.
- On the left sidebar, select Deployments > Environments.
- Select the Stopped tab.
- Next to the environment you want to delete, select Delete environment.
- On the confirmation dialog box, select Delete environment.
Access an environment for preparation or verification purposes
Introduced in GitLab 13.2.
You can define a job that accesses an environment for various purposes, such as verification or preparation. This effectively bypasses deployment creation, so that you can adjust your CD workflow more accurately.
To do so, add either action: prepare
, action: verify
, or action: access
to the environment
section of your job:
build:
stage: build
script:
- echo "Building the app"
environment:
name: staging
action: prepare
url: https://staging.example.com
This gives you access to environment-scoped variables, and can be used to protect builds from unauthorized access. Also, it's effective to avoid the prevent outdated deployment jobs feature.
Group similar environments
You can group environments into collapsible sections in the UI.
For example, if all of your environments start with the name review
,
then in the UI, the environments are grouped under that heading:
The following example shows how to start your environment names with review
.
The $CI_COMMIT_REF_SLUG
variable is populated with the branch name at runtime:
deploy_review:
stage: deploy
script:
- echo "Deploy a review app"
environment:
name: review/$CI_COMMIT_REF_SLUG
Environment incident management
Production environments can go down unexpectedly, including for reasons outside of your control. For example, issues with external dependencies, infrastructure, or human error can cause major issues with an environment. Things like:
- A dependent cloud service goes down.
- A 3rd party library is updated and it's not compatible with your application.
- Someone performs a DDoS attack to a vulnerable endpoint in your server.
- An operator misconfigures infrastructure.
- A bug is introduced into the production application code.
You can use incident management to get alerts when there are critical issues that need immediate attention.
View the latest alerts for environments (ULTIMATE)
Introduced in GitLab 13.4.
If you set up alerts for Prometheus metrics, alerts for environments are shown on the environments page. The alert with the highest severity is shown, so you can identify which environments need immediate attention.
When the issue that triggered the alert is resolved, it is removed and is no longer visible on the environments page.
If the alert requires a rollback, you can select the deployment tab from the environment page and select which deployment to roll back to.
Auto Rollback (ULTIMATE)
Introduced in GitLab 13.7.
In a typical Continuous Deployment workflow, the CI pipeline tests every commit before deploying to production. However, problematic code can still make it to production. For example, inefficient code that is logically correct can pass tests even though it causes severe performance degradation. Operators and SREs monitor the system to catch these problems as soon as possible. If they find a problematic deployment, they can roll back to a previous stable version.
GitLab Auto Rollback eases this workflow by automatically triggering a rollback when a critical alert is detected. GitLab selects and redeploys the most recent successful deployment.
Limitations of GitLab Auto Rollback:
- The rollback is skipped if a deployment is running when the alert is detected.
- A rollback can happen only once in three minutes. If multiple alerts are detected at once, only one rollback is performed.
GitLab Auto Rollback is turned off by default. To turn it on:
- On the top bar, select Main menu > Projects and find your project.
- On the left sidebar, select Settings > CI/CD.
- Expand Automatic deployment rollbacks.
- Select the checkbox for Enable automatic rollbacks.
- Select Save changes.
Monitor environments
To monitor the behavior of your app as it runs in each environment, enable Prometheus for monitoring system and response metrics. For the monitoring dashboard to appear, configure Prometheus to collect at least one supported metric.
All deployments to an environment are shown on the monitoring dashboard. You can view changes in performance for each version of your application.
GitLab attempts to retrieve supported performance metrics for any environment that has had a successful deployment. If monitoring data was successfully retrieved, a Monitoring button appears for each environment.
To view the last eight hours of performance data, select the Monitoring button. It may take a minute or two for data to appear after initial deployment.
Embed metrics in GitLab Flavored Markdown
Metric charts can be embedded in GitLab Flavored Markdown. See Embedding Metrics in GitLab Flavored Markdown for more details.
Web terminals (deprecated)
Deprecated in GitLab 14.5.
WARNING: This feature was deprecated in GitLab 14.5.
If you deploy to your environments with the help of a deployment service (for example, the Kubernetes integration), GitLab can open a terminal session to your environment. You can then debug issues without leaving your web browser.
The Web terminal is a container-based deployment, which often lack basic tools (like an editor), and can be stopped or restarted at any time. If this happens, you lose all your changes. Treat the Web terminal as a debugging tool, not a comprehensive online IDE.
Web terminals:
- Are available to project Maintainers and Owners only.
- Must be enabled.
In the UI, you can view the Web terminal by selecting Terminal from the actions menu:
You can also access the terminal button from the page for a specific environment:
Select the button to establish the terminal session:
This works like any other terminal. You're in the container created by your deployment so you can:
- Run shell commands and get responses in real time.
- Check the logs.
- Try out configuration or code tweaks.
You can open multiple terminals to the same environment. They each get their own shell
session and even a multiplexer like screen
or tmux
.
Check out deployments locally
A reference in the Git repository is saved for each deployment, so
knowing the state of your current environments is only a git fetch
away.
In your Git configuration, append the [remote "<your-remote>"]
block with an extra
fetch line:
fetch = +refs/environments/*:refs/remotes/origin/environments/*
Archive Old Deployments
- Introduced in GitLab 14.5.
- Enabled on GitLab.com and self-managed in GitLab 14.6.
- Generally available in GitLab 14.0. Feature flag
deployments_archive
removed.
When a new deployment happens in your project,
GitLab creates a special Git-ref to the deployment.
Since these Git-refs are populated from the remote GitLab repository,
you could find that some Git operations, such as git-fetch
and git-pull
,
become slower as the number of deployments in your project increases.
To maintain the efficiency of your Git operations, GitLab keeps
only recent deployment refs (up to 50,000) and deletes the rest of the old deployment refs.
Archived deployments are still available, in the UI or by using the API, for auditing purposes.
Also, you can still fetch the deployed commit from the repository
with specifying the commit SHA (for example, git checkout <deployment-sha>
), even after archive.
NOTE:
GitLab preserves all commits as keep-around
refs
so that deployed commits are not garbage collected, even if it's not referenced by the deployment refs.
Limit the environment scope of a CI/CD variable
- Introduced in GitLab Premium 9.4.
- Environment scoping for CI/CD variables was moved from GitLab Premium to GitLab Free in 12.2.
- Environment scoping for Group CI/CD variables added to GitLab Premium in 13.11.
By default, all CI/CD variables are available to any job in a pipeline. Therefore, if a project uses a compromised tool in a test job, it could expose all CI/CD variables that a deployment job used. This is a common scenario in supply chain attacks. GitLab helps mitigate supply chain attacks by limiting the environment scope of a variable.
You can limit the environment scope of a CI/CD variable by
defining which environments it can be available for.
For example, if the environment scope is production
, then only the jobs
with the environment production
defined would have this specific variable.
The default environment scope is a wildcard (*
), which means that
any job can have this variable, regardless of whether an environment is defined.
If the environment scope is review/*
, then jobs with environment names starting
with review/
would have that variable available.
In most cases, these features use the environment specs mechanism, which offers an efficient way to implement scoping in each environment group.
For example, if there are four environments:
production
staging
review/feature-1
review/feature-2
Each environment can be matched with the following environment spec:
Environment Spec | production |
staging |
review/feature-1 |
review/feature-2 |
---|---|---|---|---|
* | Matched | Matched | Matched | Matched |
production | Matched | |||
staging | Matched | |||
review/* | Matched | Matched | ||
review/feature-1 | Matched |
You can use specific matching to select a particular environment.
You can also use wildcard matching (*
) to select a particular environment group,
like Review Apps (review/*
).
The most specific spec takes precedence over the other wildcard matching. In this case,
the review/feature-1
spec takes precedence over review/*
and *
specs.

Troubleshooting
action: stop
doesn't run
The job with In some cases, environments do not stop when a branch is deleted.
For example, the environment might start in a stage that also has a job that failed.
Then the jobs in later stages job don't start. If the job with the action: stop
for the environment is also in a later stage, it can't start and the environment isn't deleted.
To ensure the action: stop
can always run when needed, you can:
-
Put both jobs in the same stage:
stages: - build - test - deploy ... deploy_review: stage: deploy environment: name: review/$CI_COMMIT_REF_SLUG url: https://$CI_ENVIRONMENT_SLUG.example.com on_stop: stop_review stop_review: stage: deploy environment: name: review/$CI_COMMIT_REF_SLUG action: stop when: manual
-
Add a
needs
entry to theaction: stop
job so the job can start out of stage order:stages: - build - test - deploy - cleanup ... deploy_review: stage: deploy environment: name: review/$CI_COMMIT_REF_SLUG url: https://$CI_ENVIRONMENT_SLUG.example.com on_stop: stop_review stop_review: stage: cleanup needs: - deploy_review environment: name: review/$CI_COMMIT_REF_SLUG action: stop when: manual
A deployment job failed with "This job could not be executed because it would create an environment with an invalid parameter" error
Introduced in GitLab 14.4.
If your project is configured to create a dynamic environment, you might encounter this error because the dynamically generated parameter can't be used for creating an environment.
For example, your project has the following .gitlab-ci.yml
:
deploy:
script: echo
environment: production/$ENVIRONMENT
Since $ENVIRONMENT
variable does not exist in the pipeline, GitLab tries to
create an environment with a name production/
, which is invalid in
the environment name constraint.
To fix this, use one of the following solutions:
- Remove
environment
keyword from the deployment job. GitLab has already been ignoring the invalid keyword, therefore your deployment pipelines stay intact even after the keyword removal. - Ensure the variable exists in the pipeline. Review the limitation on supported variables.
If you get this error on Review Apps
For example, if you have the following in your .gitlab-ci.yml
:
review:
script: deploy review app
environment: review/$CI_COMMIT_REF_NAME
When you create a new merge request with a branch name bug-fix!
,
the review
job tries to create an environment with review/bug-fix!
.
However, the !
is an invalid character for environments, so the
deployment job fails since it was about to run without an environment.
To fix this, use one of the following solutions:
-
Re-create your feature branch without the invalid characters, such as
bug-fix
. -
Replace the
CI_COMMIT_REF_NAME
predefined variable withCI_COMMIT_REF_SLUG
which strips any invalid characters:review: script: deploy review app environment: review/$CI_COMMIT_REF_SLUG
Deployment refs are not found
Starting from GitLab 14.5, GitLab deletes old deployment refs to keep your Git repository performant.
If you have to restore archived Git-refs, ask an administrator of your self-managed GitLab instance to execute the following command on Rails console:
Project.find_by_full_path(<your-project-full-path>).deployments.where(archived: true).each(&:create_ref)
GitLab might drop this support in the future for the performance concern. You can open an issue in GitLab Issue Tracker to discuss the behavior of this feature.
