DESCRIPTION
    (ALPHA) Create a build trigger for a GitHub repository.

EXAMPLES
    To create a push trigger for all branches:

        $ gcloud alpha builds triggers create github --name="my-trigger" \
            --service-account="projects/my-project/serviceAccounts/my-byosa@\
        my-project.iam.gserviceaccount.com" \
            --repo-owner="GoogleCloudPlatform" \
            --repo-name="cloud-builders" --branch-pattern=".*" \
            --build-config="cloudbuild.yaml"

    To create a pull request trigger for master:

        $ gcloud alpha builds triggers create github --name="my-trigger" \
            --service-account="projects/my-project/serviceAccounts/my-byosa@\
        my-project.iam.gserviceaccount.com" \
            --repo-owner="GoogleCloudPlatform" \
            --repo-name="cloud-builders" --pull-request-pattern="^master$" \
            --build-config="cloudbuild.yaml"

REQUIRED FLAGS
     Exactly one of these must be specified:

       --trigger-config=PATH
          Path to Build Trigger config file (JSON or YAML format). For more
          details, see
          https://cloud.google.com/cloud-build/docs/api/reference/rest/v1/projects.triggers#BuildTrigger

       Flag based trigger configuration

         --repo-name=REPO_NAME
            Name of the GitHub Repository.

            This flag must be specified if any of the other arguments in this
            group are specified.

         --repo-owner=REPO_OWNER
            Owner of the GitHub Repository.

            This flag must be specified if any of the other arguments in this
            group are specified.

         --description=DESCRIPTION
            Build trigger description.

         --ignored-files=[GLOB,...]
            Glob filter. Changes only affecting ignored files won't trigger
            builds.

         --included-files=[GLOB,...]
            Glob filter. Changes affecting at least one included file will
            trigger builds.

         --name=NAME
            Build trigger name.

         --require-approval
            Require manual approval for triggered builds.

         --service-account=SERVICE_ACCOUNT
            The service account used for all user-controlled operations
            including UpdateBuildTrigger, RunBuildTrigger, CreateBuild, and
            CancelBuild. If no service account is set, then the standard Cloud
            Build service account ([PROJECT_NUM]@system.gserviceaccount.com) is
            used instead. Format:
            projects/{PROJECT_ID}/serviceAccounts/{ACCOUNT_ID_OR_EMAIL}.

         --substitutions=[KEY=VALUE,...]
            Parameters to be substituted in the build specification.

            For example (using some nonsensical substitution keys; all keys
            must begin with an underscore):

                $ gcloud builds triggers create ... --config config.yaml
                    --substitutions _FAVORITE_COLOR=blue,_NUM_CANDIES=10

            This will result in a build where every occurrence of
            ${_FAVORITE_COLOR} in certain fields is replaced by "blue", and
            similarly for ${_NUM_CANDIES} and "10".

            Only the following built-in variables can be specified with the
            --substitutions flag: REPO_NAME, BRANCH_NAME, TAG_NAME,
            REVISION_ID, COMMIT_SHA, SHORT_SHA.

            For more details, see:
            https://cloud.google.com/cloud-build/docs/api/build-requests#substitutions

         Exactly one of these must be specified:

           --branch-pattern=REGEX
              A regular expression specifying which git branches to match.

              This pattern is used as a regex search for any incoming pushes.
              For example, --branch-pattern=foo will match "foo", "foobar", and
              "barfoo". Events on a branch that does not match will be ignored.

              The syntax of the regular expressions accepted is the syntax
              accepted by RE2 and described at
              https://github.com/google/re2/wiki/Syntax.

           --tag-pattern=REGEX
              A regular expression specifying which git tags to match.

              This pattern is used as a regex search for any incoming pushes.
              For example, --tag-pattern=foo will match "foo", "foobar", and
              "barfoo". Events on a tag that does not match will be ignored.

              The syntax of the regular expressions accepted is the syntax
              accepted by RE2 and described at
              https://github.com/google/re2/wiki/Syntax.

           Pull Request settings

             --pull-request-pattern=REGEX
                A regular expression specifying which base git branch to match
                for pull request events.

                This pattern is used as a regex search for the base branch (the
                branch you are trying to merge into) for pull request updates.
                For example, --pull-request-pattern=foo will match "foo",
                "foobar", and "barfoo".

                The syntax of the regular expressions accepted is the syntax
                accepted by RE2 and described at
                https://github.com/google/re2/wiki/Syntax.

                This flag must be specified if any of the other arguments in
                this group are specified.

             --comment-control=COMMENT_CONTROL; default=CommentControlValueValuesEnum(COMMENTS_ENABLED, 1)
                Require a repository collaborator or owner to comment '/gcbrun'
                on a pull request before running the build.

         Exactly one of these must be specified:

           Build file configuration flags

             --build-config=PATH
                Path to a YAML or JSON file containing the build configuration
                in the repository.

                For more details, see:
                https://cloud.google.com/cloud-build/docs/build-config

           Build configuration file

             --inline-config=PATH
                Local path to a YAML or JSON file containing a build
                configuration.

           Dockerfile build configuration flags

             --dockerfile=DOCKERFILE
                Path of Dockerfile to use for builds in the repository.

                If specified, a build config will be generated to run docker
                build using the specified file.

                The filename is relative to the Dockerfile directory.

             --dockerfile-dir=DOCKERFILE_DIR; default="/"
                Location of the directory containing the Dockerfile in the
                repository.

                The directory will also be used as the Docker build context.

             --dockerfile-image=DOCKERFILE_IMAGE
                Docker image name to build.

                If not specified,
                gcr.io/PROJECT/github.com/REPO_OWNER/REPO_NAME:$COMMIT_SHA will
                be used.

                Use a build configuration (cloudbuild.yaml) file for building
                multiple images in a single trigger.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,
    --trace-token, --user-output-enabled, --verbosity.

NOTES
    This command is currently in alpha and might change without notice. If this
    command fails with API permission errors despite specifying the correct
    project, you might be trying to access an API with an invitation-only early
    access allowlist. This variant is also available:
