    Manually build code in source repositories

    This page explains how to create manual triggers to build code in source repositories. Manual triggers can be used to invoke builds manually, with the ability to override defined substitution variable values at invocation time prior to running a build. You can also schedule manual triggers to automatically run at a specific time.

    To learn how to start builds manually using the gcloud CLI or the Cloud Build API, see Starting builds manually .

    Before you begin

    • Enable the Cloud Build API.

      Roles required to enable APIs

      To enable APIs, you need the Service Usage Admin IAM role ( roles/serviceusage.serviceUsageAdmin ), which contains the serviceusage.services.enable permission. Learn how to grant roles .

      Enable the API

    • Have your source code ready.

    Manual triggers

    Manual triggers enable you to set up builds that are only executed when you invoke your trigger on connected repositories. For example, you create a pipeline for deploying your source code to a staging or production environment. You might want to automate your workflow, but are only looking to execute builds manually. You can define manual triggers to do so.

    Manual triggers enable you to manually invoke builds by:

    • Fetching source code from a hosted repository with a specified branch or tag.
    • Parameterizing your build with substitutions that don't need to be passed in manually each time you execute a build.
    • Overriding defined substitution variable values at invocation time prior to invoking a build.

    If you want to execute builds from your local working directory instead of a hosted repository or want to submit builds without creating a trigger, you can run the following gcloud command in your working directory:

     gcloud builds submit --config BUILD_CONFIG 
 SOURCE_CODE

    Where:

    • BUILD_CONFIG is the path to the build config file.
    • SOURCE_CODE is the path or URL source code.

    To learn more about how to use the gcloud command to start builds manually in your local directory, see Starting builds manually .

    Creating manual triggers

    Console

    To create a manual trigger:

    1. Open the Triggerspage:

      Open the Triggers page

    2. Select your project from the top of the page and click Open.

    3. Click Create trigger.

    4. Enter the following trigger settings:

      • Name: A name for your trigger.

      • Region: Select the region for your trigger.

        • If you select globalas the region, Cloud Build uses the default pool to run your build.
        • If you select a non-global region and the build config file associated with the trigger specifies a private pool , Cloud Build uses the private pool to run your build. In this case, the region you specify in your trigger must match the region where you created your private pool.
        • If you select a non-global region and the build config file associated with the trigger does notspecify a private pool, Cloud Build uses the default pool to run your build in the same region as your trigger.

      • Description(Optional): A description for your trigger.

      • Event: Select Manual invocationto set up your trigger so that builds only run when the trigger is manually invoked.

      • Source: Select the repository to build when the manual trigger runs.

        Caution:Effective June 17, 2024, Cloud Source Repositories isn't available to new customers. If your organization hasn't previously used Cloud Source Repositories, you can't enable the API or use Cloud Source Repositories. New projects not connected to an organization can't enable the Cloud Source Repositories API. Organizations that have used Cloud Source Repositories prior to June 17, 2024 are not affected by this change.

      • Repository generation: Select 2nd gen.

      • Branchor Tag: Set one of the following:

        • Branch: Set a trigger to build on this branch. You must specify a literal value. Regular expressions aren't supported.
        • Tag: Set a trigger to build on this tag. You must specify a literal value. Regular expressions aren't supported.

      • Configuration: Select the build config file located in your remote repository or create an inline build config file to use for your build.

        • Type: Select the type of configuration to use for your build.
          • Cloud Build configuration file (yaml or json): Use a build config file for your configuration.
          • Dockerfile: Use a Dockerfile for your configuration.

        • Location: Specify the location for your configuration.

          • Repository: If your config file is located in your remote repository, provide the location of your build config file , the Dockerfile directory, or the buildpacks directory. If your build config type is a Dockerfile or a buildpack, you will need to provide a name for the resulting image and optionally, a timeout for your build. When you've provided the Dockerfile or buildpack image name, you'll see a preview of the docker build or pack command that your build will execute.
          • Inline: If you selected Cloud Build configuration file (yaml or json)as your configuration option, you can specify your build config inline. Click Open Editorto write your build config file in the Google Cloud console using YAML or JSON syntax. Click Doneto save your build config.

    5. Click Createto create your manual trigger.

    gcloud

    Preview — Manual triggers: Cloud Build repositories (2nd gen) support

    This feature is subject to the "Pre-GA Offerings Terms" in the General Service Terms section of the Service Specific Terms . You can process personal data for this feature as outlined in the Cloud Data Processing Addendum , subject to the obligations and restrictions described in the agreement under which you access Google Cloud. Pre-GA features are available "as is" and might have limited support. For more information, see the launch stage descriptions .

    To create a manual trigger:

    1. Open a terminal window.

    2. Run the following gcloud command to create a build trigger in your project:

        gcloud 
  
 builds 
  
 triggers

    Running manual triggers

    Console

    To run a manual trigger using Google Cloud console:

    1. Open the Triggerspage in the Google Cloud console.

      Open the triggers page

    2. Locate your trigger in the list.

    3. Click Run trigger.

      After clicking Run trigger, you will see the Run triggerwindow pane on the right side. If you specified fields such as a branch name, tag name, or substitution variables, you will be able to override these fields at invocation time.

      If the trigger uses a repository with more than 500 branches or tags, some of them may be missing from the suggestions. You can still enter a branch or tag name manually.

      If you specified new variable values for your substitution, click Run triggerto execute your build.

      To run manual triggers on schedule, see Scheduling builds .

    gcloud

    To run a manual trigger using the gcloud command-line tool, run the following command:

       
 gcloud 
  
 builds 
  
 triggers 
  
 run 
  
  TRIGGER_NAME 
 
  
 \ 
  
 -- 
 region 
 = 
  REGION 
 
  
 \ 
  
 -- 
 branch 
 = 
  BRANCH_NAME 
 
  
 \

 = 
  SUBSTITUTION_VALUE

    Where:

    • TRIGGER_NAME is the name of your trigger.
    • REGION is the region for your trigger.
    • BRANCH_NAME is the name of your branch. You can also specify a tag using --tag or a commit ID using --sha .
    • SUBSTITUTION_VAR (Optional) is the variable name for your substitution value.
    • SUBSTITUTION_VALUE (Optional) is the value associated with your substitution variable.

    To run manual triggers on schedule, see Scheduling builds .
