gitlab-ci.yml only on master branch - gitlab

I have a gitlab-ci.yml file like this, and want to run it only on Branch Master. If there is a push into develop branch the Pipeline should NOT start.
I tried with 'only' keyword, but it shows an Error.
stages:
- info
- build
- test
- review
- cleanup
- deploy-dev
- integration-test
- deploy-test
- system-test
- deploy-production
only:
refs:
- master

To define a trigger rule for every stage you can use the workflow keyword, like this:
workflow:
rules:
- if: $CI_COMMIT_TAG
when: never
- if: $CI_COMMIT_BRANCH == 'master'
This has to be on the "root" of your yaml, as it is not part of any job in particular.
In the example above, I am telling the pipeline to avoid running when a repository tag is pushed and to run only when a commit is done in the master branch.
You can use this as a base and add other conditions to trigger the stages in the pipeline, the complete documentation on this matters can be found here: https://docs.gitlab.com/ee/ci/yaml/#workflow

I thin you have an indentation problem here.
It should be something like:
stages:
- job_1
- job_2
- ....
- job_n
job_1:
stage: job_1
....
only:
refs:
- master
job_2:
stage: job_2
....
only:
refs:
- master
....
You need to define the target branch for each stage.

How to exclude gitlab-ci.yml changes from triggering a job

I am unable to find a solution for how to ignore changes made in .gitlab-ci.yml to trigger a job. So far I have tried the below options:
except:
changes:
- .gitlab-ci.yml
and
only
- Branch A
but every time i make changes in .gitlab.ci-yml file, jobs for Stage B get added in pipeline and show as skipped.
Below are the jobs defined in .gitlab-ci.yml. Do you have any suggestion here?
I do not want Stage B jobs get added in pipeline when:
i) push made against the .gitlab-ci.yml (either manual changing file or git push command)
ii) any merge request for .gitlab-ci.yml
stages:
- A
- B
Stage A:
stage: A
script:
- echo "TEST"
rules:
- if: '$CI_COMMIT_TAG =~ /^\d+\.\d+\.DEV\d+/'
tags:
- runner
Stage B:
stage: B
script:
- echo "TEST"
when: manual
tags:
- runner
With this setup the Stage B is not added if .gitlab-ci.yml is modified:
stages:
- A
- B
Stage A:
stage: A
script:
- echo "Stage A"
tags:
- runner
Stage B:
stage: B
script:
- echo "Stage B"
rules:
- changes:
- ".gitlab-ci.yml"
when: never
- when: manual
tags:
- runner
Otherwise Stage B is showed in the pipeline and can be run manually. Tested with GitLab CI CE 14.1.0.
Could you try using workflow rule? It should determine if the pipeline is created.
P.S: Someone complained a couple of years ago about not being able to activate manual jobs after the exception, but it looks like it was a bug. I can't find the issue mentioned in the post
Edit:
This conf skips any commit with changes README.md or .gitlab-ci.yml:
workflow:
rules:
- if:
changes:
- README.md
- .gitlab-ci.yml
when: never

"Only" or "rules" keywords weirdly remove jobs from the CI pipeline

I am trying to use "rules" and "only" keywords to define my pipeline behaviors between merge requests, pushes into dev branch and pushes into master branch.
I noticed several weird behaviors in the Gitlab CI, let's see in my merge_requests pipelines.
With this gitlab-ci.yml file, without any rule, all the jobs are displayed and run.
image: "python:3.8"
stages:
- test_without_only_policy
- test_with_only_policy
test_without_only_policy:
stage: test_without_only_policy
when: manual
script:
- echo "Yay, I am in the pipeline"
test_with_only_policy:
stage: test_with_only_policy
script:
- echo "I am always in the pipeline"
Everything is working as expected, great 👍
With this gitlab-ci.yml file, without an "only" policy in the 2nd job, the 1st job without rules disappears.
image: "python:3.8"
stages:
- test_without_only_policy
- test_with_only_policy
test_without_only_policy:
stage: test_without_only_policy
when: manual
script:
- echo "No, I am not in the pipeline anymore"
test_with_only_policy:
stage: test_with_only_policy
only:
- merge_requests
script:
- echo "I am always in the pipeline"
Why did the 1st job without the rules or "only" policy disappear?
With this gitlab-ci.yml file, with a "rules" keyword in the 2nd job, the 1st job without rules disappears.

test_with_only_policy:

Thank you for your help, I don't understand why my job disappears when I add rules in other jobs.
According to the documentation for Merge Request Pipelines, if you have a pipeline where only some jobs use only/except/rules with merge_requests, only those jobs will be in the pipeline if it is a Merge Request pipeline. The other jobs will be left out.
Here's the example from the docs:
build:
stage: build
script: ./build
only:
- main
test:
stage: test
script: ./test
only:
- merge_requests
deploy:
stage: deploy
script: ./deploy
only:
- main
In this example, the only job that specifies it should run for Merge Request pipelines is the test job. For standard push pipelines, the build and deploy jobs will run, but when a new merge request is created, a change is pushed to a branch that is the source branch on an existing merge request, or you hit the Run Pipeline button on the Pipelines tab for a Merge Request, it will run a Merge Request pipeline.
Here's another example with a different scenario:
A:
stage: some_stage
only:
- branches
- tags
- merge_requests
script:
- script.sh
B:
stage: some_other_stage
only:
- branches
- tags
- merge_requests
script:
- script.sh
C:
stage: third_stage
only:
- merge_requests
script:
- script.sh
In this example, jobs A and B run for all pipeline types push, tags, merge_requests, etc., but job C only runs for merge_request pipelines.
That's why your test_without_only_policy job will never be in a pipeline where test_with_only_policy runs. test_with_only_policy specifically runs for Merge Request events, but test_without_only_policy does not.

Adds needs relations to GitLab CI yaml but got an error: the job was not added to the pipeline

I am trying to add needs between jobs in the Gitlab CI yaml configuration file.
stages:
- build
- test
- package
- deploy
maven-build:
stage: build
only:
- merge_requests
- master
- branches
...
test:
stage: test
needs: [ "maven-build" ]
only:
- merge_requests
- master
...
docker-build:
stage: package
needs: [ "test" ]
only:
- master
...
deploy-stage:
stage: deploy
needs: [ "docker-build" ]
only:
- master
...
deploy-prod:
stage: deploy
needs: [ "docker-build" ]
only:
- master
when: manual
...
I have used the GitLab CI online lint tools to check my syntax, it is correct.
But when I pushed the codes, it always complains:
'test' job needs 'maven-build' job
but it was not added to the pipeline
You can also test your .gitlab-ci.yml in CI Lint
The GitLab CI did not run at all.
Update: Finally I made it. I think the needs position is sensitive, move all needs under the stage, it works. My original scripts included some other configuration between them.
CI-jobs that depend on each other need to have the same limitations!
In your case that would mean to share the same only targets:
stages:
- build
- test
maven-build:
stage: build
only:
- merge_requests
- master
- branches
test:
stage: test
needs: [ "maven-build" ]
only:
- merge_requests
- master
- branches
that should work from my experience^^
Finally I made it. I think the needs position is sensitive, move all needs under the stage, it works
Actually... that might no longer be the case with GitLab 14.2 (August 2021):
Stageless pipelines
Using the needs keyword in your pipeline configuration helps to reduce cycle times by ignoring stage ordering and running jobs without waiting for others to complete.
Previously, needs could only be used between jobs on different stages.
In this release, we’ve removed this limitation so you can define a needs relationship between any job you want.
As a result, you can now create a complete CI/CD pipeline without using stages by including needs in every job to implicitly configure the execution order.
This lets you define a less verbose pipeline that takes less time to create and can run even faster.
See Documentation and Issue.
The rule in both jobs should be that same or otherwise GitLab cannot create job dependency between the jobs when the trigger rule is different.
I don't know why, but if the jobs are in different stages (as in my case), you have to define the jobs that will be done later with "." at the start.
Another interesting thing is GitLab's own CI/CD Lint online text editor does not complain there is an error. So you have to start the pipeline to see the error.
Below, notice the "." in ".success_notification" and ".failure_notification"
stages:
- prepare
- build_and_test
- deploy
- notification

Accept merge request without running manual stages

I have a pipeline with 3 stages: build, deploy-test and deploy-prod. I want stages to have following behavior:
always run build
run deploy-test automatically when on master or manually when on other branches
run deploy-prod manually, only available on master branch
My pipeline configuration seems to achieve that but I have a problem when trying to merge branches into master. I don't want to execute deploy-test stage on every branch before doing merge. Right now I am required to do that as the merge button is disabled with a message Pipeline blocked. The pipeline for this merge request requires a manual action to proceed. The setting Pipelines must succeed in project is disabled.
I tried adding additional rule to prevent deploy-test stage from running in merge requests but it didn't change anything:
rules:
- if: '$CI_MERGE_REQUEST_ID'
when: never
- if: '$CI_COMMIT_BRANCH == "master"'
when: on_success
- when: manual
Full pipeline configuration:
stages:
- build
- deploy-test
- deploy-prod
build:
stage: build
script:
- echo "build"
deploy-test:
stage: deploy-test
script:
- echo "deploy-test"
rules:
- if: '$CI_COMMIT_BRANCH == "master"'
when: on_success
- when: manual
deploy-prod:
stage: deploy-prod
script:
- echo "deploy-prod"
only:
- master
The only way I got it to work was to set ☑️ Skipped pipelines are considered successful in Setttings > General > Merge requests > Merge Checks
and marking the manual step as "allow_failure"
upload:
stage: 'upload'
rules:
# Only allow uploads for a pipeline source whitelisted here.
# See: https://docs.gitlab.com/ee/ci/jobs/job_control.html#common-if-clauses-for-rules
- if: $CI_COMMIT_BRANCH
when: 'manual'
allow_failure: true
After this clicking the Merge when Pipeline succeeds button …
… will merge the MR without any manual interaction:
I've opened a merge request from branch "mybranch" into "master" with the following .gitlab-ci.yml:
image: alpine
stages:
- build
- deploy-test
- deploy-prod
build:
stage: build
script:
- echo "build"
# run deploy-test automatically when on master or manually when on other branches
# Don't run on merge requests
deploy-test:
stage: deploy-test
script:
- echo "deploy-test"
rules:
- if: $CI_MERGE_REQUEST_ID
when: never
- if: '$CI_COMMIT_BRANCH == "master"'
when: on_success
- when: manual
# run deploy-prod manually, only available on master branch
deploy-prod:
stage: deploy-prod
script:
- echo "deploy-prod"
rules:
- if: '$CI_COMMIT_BRANCH == "master"'
when: manual
Notes:
only is deprecated, so I replaced it with if
I added Alpine image to make the jobs run faster (slimmer container); it doesn't affect the logic
When I pushed changes to branch "mybranch", GitLab did the following:
showed a blue "Merge when pipeline succeeds" button on my MR
ran "build" stage
skipped "deploy-prod" stage (only available on "master" branch)
gave me a manual "play" button to run the job on "mybranch"
at this point, the pipeline status is "blocked" and the MR is showing "Pipeline blocked. The pipeline for this merge request requires a manual action to proceed"
now I manually start the "deploy-test" stage by selecting the Play icon in the Pipelines screen
pipeline status indicator changes to "running" and then to "passed"
my merge request shows the pipeline passed and gives me the green "Merge" button
There are a number of variables that are available to the pipeline on runtime - Predefined variables reference
Some are available specifically for pipelines associated with merge requests - Predefined variables for merge request pipelines
You can utilize one or more of these variables to determine if you would want to run the deploy-test job for that merge request.
For example, you could use mention the phrase "skip_cicd" in your merge request title, access it with CI_MERGE_REQUEST_TITLE variable and create a rule. Your pipeline would look somewhat like this (please do test the rule, I have edited the pipeline off the top of my head and could be wrong) -
stages:
- build
- deploy-test
- deploy-prod
build:
stage: build
script:
- echo "build"
deploy-test:
stage: deploy-test
script:
- echo "deploy-test"
rules:
- if: '$CI_MERGE_REQUEST_TITLE == *"skip_cicd"*'
when: never
- if: '$CI_COMMIT_BRANCH == "master"'
when: on_success
- when: manual
deploy-prod:
stage: deploy-prod
script:
- echo "deploy-prod"
only:
- master

Combine only schedule and branch in GitLab CI

is it possible to combine schedule and a specific branch in a GitLab ci task like:
do_my_task:
stage: deploy-it
script:
- do-something.sh
only:
- my-branch
- schedules
In my case it seems the the branch restriction won't work.
Any ideas?
Try to apply refs
do_my_task:
stage: deploy-it
script:
- do-something.sh
only:
refs:
- my-branch
- schedules
As suggested in Gitlab manual
