gitlab pass variables to child pipeline gitlab pass variables to child pipeline
You can use predefined CI/CD variables in your .gitlab-ci.yml without declaring them first. This answer's final API urls look like they auto-resolve to the last-run job of a given branch, perhaps they could still work? Since commit SHAs are not supported, $CI_COMMIT_BEFORE_SHA or $CI_COMMIT_SHA do not work either. Since artifacts can be passed between stages, you can try writing the variables into a file such as JSON, and parse it in another job. For example, in a multi-project pipeline: Set the test job in the downstream pipeline to inherit the variables from the build_vars The following code illustrates configuring a bridge job to trigger a downstream pipeline: //job1 is a job in the upstream project deploy: stage: Deploy script: this is my script //job2 is a bridge . The important values are the trigger keys which define the child configuration file to run, and the parent pipeline continues to run after triggering it. They can also be interpolated into the values of other fields in your .gitlab-ci.yml file, enabling dynamic pipeline configuration: GitLab CI defines several built-in variables that are always available. In pipeline mini graphs, the downstream pipeline However, it can Here is an example: The artifact containing the generated YAML file must not be larger than 5 MB. You can use variables to supply config values, create reusable pipelines, and avoid hardcoding sensitive information into your .gitlab-ci.yml files. and needs:project. This manual pipeline reduces the chances . always displays: Use the trigger keyword in your .gitlab-ci.yml file all variables containing sensitive information should be masked in job logs. For example: The UPSTREAM_BRANCH variable, which contains the value of the upstream pipelines $CI_COMMIT_REF_NAME The Managing the Complex Configuration Data Management Monster Using GitLab Let "building" happen all the time, and limit "deploy" to main branch. but they can be used in job scripts. Going by the Gitlab docs, it should be possible to download any job's artifact by URL, if it hasn't expired yet. all variables become available to the pipeline. Multi-project pipelines are useful for larger products that require cross-project inter-dependencies, such as those adopting a microservices architecture. Is there a way to make the pipelines "related"? start pipelines in the downstream project, otherwise the downstream pipeline fails to start. You can always override a variable later in specific projects that need a different value. Where does gitlab-runner download job artifacts zip file? by the runner and makes job logs more verbose. Dynamic Child Pipelines with Jsonnet. CI/CD variables are a type of environment variable. To create a CI/CD variable in the .gitlab-ci.yml file, define the variable and Then the source build.env command fails because build.env does not exist. in Bash or dir env: in PowerShell. With the new Parent-child pipelines it's not clear how to pass through variables from the parent to the child in the docs. Hover over a pipeline card to have the job that triggered the downstream pipeline highlighted. For example, VAR1: 012345 Variables can be managed at any time by returning to the settings screen of the scope theyre set in. optionally be set as a file type (variable_type of file in the API). accessing variable values. Assume, that we have the following parent pipeline that triggered a child pipeline and a downstream pipeline in another project and pass a variable to the downstream pipeline. Dotenv is a standardized way to handle environment variables. Variables saved in the .gitlab-ci.yml file are visible to all users with access to Now, I want, that the value of the variable MODULE_A_VERSION of the child pipeline is pass to the downstream pipeline. can view job logs. the repository, and should store only non-sensitive project configuration. You can set variables using the GitLab UI or the API; were concentrating on the UI in this guide. You can configure Auto DevOps to pass CI/CD variables You must have administrator access to the instance. Where can I find a clear diagram of the SPECK algorithm? Next use the Variables table to define variables to add to this pipeline run. When you have another or better approach how to solve this described problem, let me know and please write a comment. The variable is available for all subsequent pipelines. We use artifacts to save the generated child configuration files for this CI run, making them available for use in the child pipelines stages. The setting is disabled by default. keyword, then trigger the downstream pipeline with a trigger job: Use needs:project in a job in the downstream pipeline to fetch the artifacts. the commit on the head of the branch to create the downstream pipeline. made the API call. For example, you can store multiple values separated by a space in a variable, Each shell has its own set of reserved variable names. You can add CI/CD variables to a projects settings. Again I get "Removing build.env" as shown in the screenshot. To learn more, see our tips on writing great answers. is triggered or running. 565), Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. In the example above, the child pipeline only triggers when changes are made to files in the cpp_app folder. Get rid of, @Peter Sadly this doesn't work. Enable this feature by using the projects API Can't do it in GraphQL directly, so I'm doing it in Python. To have no environment variables from a dotenv artifact: You cannot create a CI/CD variable that is an array of values, but you When you merge, main will take on the VERSION from the branch. Using both is not allowed. You should also look at GitLab CI/CD variables | GitLab. This data can only be read and decrypted with a I did try this some time ago but I didn't get it to work. What does 'They're at four. It exists two ways how a downstream pipeline can consume a variable from a child pipeline of its upstream pipeline. In this release weve added a new trigger:forward keyword to control what things you forward to downstream parent-child pipelines or multi-project pipelines, which provides a flexible way to handle variable inheritance in downstream pipelines. pipeline trigger API endpoint These variables all have the same (highest) precedence: Variables defined outside of jobs (globally) in the. are both tools that use File type variables for configuration. I might test it myself. Consider the following example (full yml below): I have two stages, staging and deploy. Insufficient permissions to set pipeline variables error message. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. GitLab CI/CD makes a set of predefined CI/CD variables available for use in pipeline configuration and job scripts. When the Type dropdown is left at Variable, this value will be injected as-is each time you reference the variable in your pipeline. valid secrets file. The group variables that are available in a project are listed in the projects How to include artifact generated data into code? By submitting your email, you agree to the Terms of Use and Privacy Policy. Introduced in GitLab 13.12, the ~ character can be used in masked variables. This relationship also enables you to compartmentalize configuration and visualization into different files and views. Use cURL You can use cURL to trigger pipelines with the pipeline triggers API endpoint. If you didn't find what you were looking for, ', referring to the nuclear power plant in Ignalina, mean? Limiting that value to only the pipelines that actually need it (like deployment jobs running against your protected release branch) lowers the risk of accidental leakage. Connect and share knowledge within a single location that is structured and easy to search. One pipeline runs on (one of) the parent commit, the next one on the following commit. does not display in job logs. In the GitLab configuration file we have: a generation job and a trigger job. Adding EV Charger (100A) in secondary panel (100A) fed off main (200A). You must be a project member with the Maintainer role. Let's start with the parent pipeline configuration file: During our self-defined setup stage the pipeline runs the write-config.rb script. Head to your project's CI/CD > Pipelines page and click the blue "Run pipeline" button in the top-right. In our case, we're grabbing the artifact archive URL directly; but somebody else might want to use the job id as input for some other API call. are recursively inherited. The output contains the content of But sadly this doesn't work. What if there were merge conflicts? Any unintentional echo $SECRET_VALUE will be cleaned up, reducing the risk of a user seeing a sensitive token value as they inspect the job logs using the GitLab web UI. all variables and other secrets available to the job. To help large and complex projects manage their automated workflows, we've added two new features to make pipelines even more powerful: Parent-child pipelines, and the ability to generate pipeline configuration files dynamically. Not the answer you're looking for? Thanks in advance. This answer of the stackoverflow post Gitlab ci cd removes artifact for merge requests suggests to use the build.env as a normal file. CopyrightCOPYRIGHT 20112023, SANDRA PARSICK; ALL RIGHTS RESERVED.. All Rights Reserved. When restricted, only users with Docs should be updated on the Parent-child pipelines page to show users how to do this also. Masking only works for values up to 4 KiB in size. For your case, assuming the 'building' and 'deploying' jobs both run on the main branch, you can hopefully pass the artifact like so. Instance-level variables are located via the same route in the GitLab Admin Area. ): every active branch or tag (a.k.a. Are there any canonical examples of the Prime Directive being broken that aren't shown on screen? Making statements based on opinion; back them up with references or personal experience. During working with GitLab multi-project pipelines and parent-child pipelines, I have encountered the problem how to pass variables through these pipelines. For this article, it's a Ruby script that writes the child pipeline config files, but you can use any scripting language. If you store your CI/CD configurations in a different repository, temporary merge commit, not a branch or tag, do not have access to these variables. Similarly, for group-level variables, navigate to the group and use the sidebar to reach its CI settings. environment variables must be surrounded by quotes to expand properly: To access CI/CD variables in Windows Batch, surround the variable with %: You can also surround the variable with ! GitLabs predefined variables are always set first. with K8S_SECRET_. You trigger a child pipeline configuration file from a parent by including it with the include key as a parameter to the trigger key. The parent pipeline, defined in .gitlab-ci.yml, triggers the child pipeline, that is defined in pipelines/child-pipeline.yml. The (relevant) yml is the following: The result is the same as above. A second way solves this disadvantage. Since we launched in 2006, our articles have been read billions of times. Currently with Gitlab CI there's no way to provide a file to use as environment variables, at least not in the way you stated. stage: build Next set the value of your variable. Yeah, manually tagging commits is probably the easiest way to get this working. If GitLab is running on Linux but using a Windows to enable the restrict_user_defined_variables setting. You can mask a project, group, or instance CI/CD variable so the value of the variable The format of the file must be one variable definition per line. To access environment variables, use the syntax for your runner executors shell. rev2023.5.1.43405. child-pipeline: trigger: include: child.gitlab-ci.yml strategy: depend variables: PARENT_PIPELINE_ID: $CI_PIPELINE_ID MY_VARIABLE: $MY_VARIABLE And if I manually set a value in Run Pipeline, this works - both the parent and child pipelines have the correct value of MY_VARIABLE. disable variable expansion for the variable. on what other GitLab CI patterns are demonstrated are available at the project page. Connect and share knowledge within a single location that is structured and easy to search. Debug logging can be a serious security risk. to store and retrieve secrets. Be 8 characters or longer, consisting only of: Characters from the Base64 alphabet (RFC4648). Splitting complex pipelines into multiple pipelines with a parent-child relationship can improve performance by allowing child pipelines to run concurrently. Expand the Variables section to view any variables that have already been defined. CI/CD variable with ($): To access variables in a Windows PowerShell environment, including environment the child pipeline must use workflow:rules or rules to ensure the jobs run. If I get around to testing in the future, I'll update my answer. Also the yml file shown below is heavily inspired by this example. Most common authentication token formats, as well as all Base64-encoded data, will be compatible. To make a UI-defined variable available in a service container, The ENVIRONMENT variable is available in every job defined in the downstream pipeline. For more information about advanced use of GitLab CI/CD, see 7 advanced GitLab CI workflow hacks shared by GitLab engineers. In addition, you can use the Gitlab API to download (unexpired) artifacts from other projects, too; and you can use the Gitlab API to mark a job's artifacts for keeping-regardless-of-expiry-policy, or to delete an artifact. merge request pipelines: You can use include:project in a trigger job The value of the variable must: Different versions of GitLab Runner have different masking limitations: You can configure a project, group, or instance CI/CD variable to be available Has the cause of a rocket failure ever been mis-identified, such that another launch failed due to the same problem? help when a variable is accidentally revealed. I get the same output as shown in the screenshot in my question. How to exclude gitlab-ci.yml changes from triggering a job, Artifacts are not pulled in a child pipeline, Stop detach pipelines from getting created, Gitlab: artifacts don't pass to child pipeline if job fails, How to access artifacts in next stage in GitLab CI/CD, Ubuntu won't accept my choice of password. How to merge artifacts across jobs for the same stage in Gitlab CI? To trigger a pipeline for a specific branch or tag, you can use an API call to the pipeline triggers API endpoint. available to the job. The output is uploaded to the Variables are created on the Settings > CI/CD > Variables screen of the scope you want them to be available in. Let's start, how to publish the variable that are defined in a child pipeline. Self-hosted GitLab administrators can use instance variables to expose common shared values, although this could cause unintentional information exposure if not carefully managed. Variable names are limited by the shell the runner uses Then print either the job id or the artifact archive url. But in the last step I want to pass this variable to a downstream pipeline: trigger-deployment: stage: trigger_deploy variables: VERSION: $VERSION trigger: project: my/project This doesn't work. If the job/variable/project/branch of the upstream pipeline changes its name, the downstream pipeline doesn't recognize this change automatically, and it couldn't work anymore as expected. You can use predefined CI/CD variables in your .gitlab-ci.yml without declaring them first. This problem is especially true for the increasingly popular "monorepo" pattern, where teams keep code for multiple related services in one repository. At their simplest variables are key-value pairs which are injected as environment variables into your pipelines execution context. and stored in the database. Run a command that saves the value of the variable in a file. Have tried artifacts etc but i couldn't find a way to pass them on to the next pipelines. See if GitLab 14.10 (April 2022) can help: Previously, it was possible to pass some CI/CD variables to a downstream pipeline through a trigger job, but variables added in manual pipeline runs or by using the API could not be forwarded. upstream pipeline: In the upstream pipeline, save the artifacts in a job with the artifacts GitLab sets pipelines triggered 565), Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. shell. Along with the listed ways of using and defining variables, GitLab recently introduced a feature that generates pre-filled variables from .gitlab-ci.yml file when there's a need to override a variable or run a pipeline manually. script: The variables set at the instance, group, and project level are layered in. But since I need the artifacts in a non-merge-request pipeline, I cannot use the suggested CI_MERGE_REQUEST_REF_PATH. Create a trigger token is there such a thing as "right to be heard"? you can set the trigger job to show the downstream pipelines status Since the parent pipeline in .gitlab-ci.yml and the child pipeline run as normal pipelines, they can have their own behaviors and sequencing in relation to triggers. Code pushed to the .gitlab-ci.yml file could compromise your variables. To add or update variables in the project settings: After you create a variable, you can use it in the .gitlab-ci.yml configuration Using the https://docs.gitlab.com/ee/ci/yaml/#triggerforward keyword you can block variables from passing to a child pipeline (and overrides global variables) trigger_child: trigger: forward: yaml_variables: false @furkanayhan can you confirm, or do you believe we have a hidden bug somewhere? You trigger a child pipeline configuration file from a parent by including it with the include key as a parameter to the trigger key. can use shell scripting techniques for similar behavior. GitLab CI/CD makes a set of predefined CI/CD variables Gitlab's GraphQL API makes it possible to get, in JSON, a list of jobs for a project + artifact urls for each job. The name you choose must be compatible with the shell thatll run your job if you pick a reserved keyword, your job could fail. And the. make sure there are no confidentiality problems. This can be a safer way to inject sensitive data if your application is prepared to read the final value from the specified file. Click the Edit button (pencil icon) next to any variable to display the editing dialog and change the variables properties. GitLab CIs Variables system lets you inject data into your CI job environments. For more information, please visit the dotenv homepage.

I also found the answer of the stackoverflow post Use artifacts from merge request job in GitLab CI which suggests to use the API together with $CI_JOB_TOKEN. You'll need the numeric project ID -- that's $CI_PROJECT_ID, if your script is running in Gitlab CI. then in script do export/copy to the file, for example: To make it working, just try to solve passing problems, keep dependencies and to keep artifacts just use "needs", avoid clearing artifacts within job. the script of the job and cant be used to configure it, for example with rules or artifact:paths. As applications and their repository structures grow in complexity, a repository .gitlab-ci.yml file becomes difficult to manage, collaborate on, and see benefit from. by using needs:project and the passed variable as the ref: You can use this method to fetch artifacts from upstream merge request pipeline, and set include: artifact to the generated artifact: In this example, GitLab retrieves generated-config.yml and triggers a child pipeline To trigger a child pipeline from a dynamically generated configuration file: Generate the configuration file in a job and save it as an artifact: Configure the trigger job to run after the job that generated the configuration file, Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. available for use in pipeline configuration and job scripts. If you dont want globally defined variables to be available in a job, set variables From this view, you can: To retry failed and canceled jobs, select Retry (): You can recreate a downstream pipeline by retrying its corresponding trigger job. These include details of the commit, branch, and merge request that the pipelines running against. So how will I be able to get values from a child pipeline ? Also ideally, somebody will try out the code above and leave a comment whether they get it to work. Use masked CI/CD variables to improve the security of trigger tokens. The precedence order is relatively complex but can be summarized as the following: You can always run a pipeline with a specific variable value by using manual execution. I feel like this is the way it should work. To cancel a downstream pipeline that is still running, select Cancel (): You can mirror the status of the downstream pipeline in the trigger job Even though that's not what I wanted to hear. - helloGitLab.exe. script: In a job in the upstream pipeline, save the artifacts using the, The user that creates the upstream pipeline does not have, The downstream pipeline targets a protected branch and the user does not have permission To subscribe to this RSS feed, copy and paste this URL into your RSS reader. You can name the child pipeline file whatever you want, but it still needs to be valid YAML. Variables are supported at the instance, group, project, and pipeline level, giving you flexibility when setting fallback values, defaults, and overrides. instead. To fetch the artifacts from the upstream merge request pipeline instead of the branch pipeline, I solved my problem already by tagging commits (tags can be pulled and therefore are easy to get). Variables passed to child pipelines are currently 5th - Inherited variables. Variable type variables: Project, group, and instance CI/CD variables are variable type by default, but can You can list all variables available to a script with the export command Settings > CI/CD > Variables section. by default can only access variables saved in the .gitlab-ci.yml file. Use needs:project to fetch artifacts from an You cannot use this method to forward job-level persisted variables Variables are available within the jobs environment. At the top level, its globally available and all jobs can use it. You can try it out by pasting it into Gitlab's GraphQL explorer. For merge request pipelines, the ref value is in the form of refs/merge-requests/
