Cloud Native Build supports configuring custom buttons on the page to trigger pipeline execution by clicking (only supports triggering web custom events). It also supports inputting environment variables on the page.

The effect is as follows:

Tips

Currently, custom buttons can only be configured on the Code-Branch Details Page.

Custom Button Configuration

Add a .cnb/web_trigger.yml file in the repository root directory to configure custom buttons. Note that the .cnb/web_trigger.yml configuration file does not support include and imports syntax.

# .cnb/web_trigger.yml
branch:
  # The following buttons are displayed on the branch details page where the branch name starts with release
  - reg: "^release"
    buttons:
      - name: Button Name 1
        # If exists, it will be used as the pipeline title, otherwise the pipeline will use the default title
        description: Button Description
        event: web_trigger_one # CI event name to trigger
        # Permission control, if not configured, users with repository write permission can trigger the build
        # If configured, repository write permission is required, and either roles or users must be satisfied to have permission to trigger the build
        permissions:
          # Configure either roles or users or both, satisfying either one is sufficient
          # The roles do not have an upward inclusion relationship. For example, in the following configuration, only users with the "master" or "developer" roles have permissions. Even if the "owner" has higher repository permissions, they are not granted access here.
          roles:
            - master
            - developer
          users:
            - name1
            - name2
        # Environment variables
        env:
          # Default environment variables, where key values (a,b,c) are environment variable names, supporting the following two formats
          a: 1
          b: 2
          c:
            # Environment variable alias
            name: Variable c
            # Environment variable value
            value: 3
        # Input environment variables, can override the above env variable configuration
        inputs:
          # Currently supports three formats: input box (input), multi-line text input box (textarea), dropdown selection box (select supports single and multiple selection), switch
          # Where key values (var1, var2, var3, var4, var5) are environment variable names
          var1:
            # Input box

  # The following buttons are displayed on the branch details page where the branch name starts with dev
  - reg: "^dev"
    buttons:
      - name: Button Name 2
        description: Button Description
        event: web_trigger_two
      - name: Button Name 3

  # The following custom buttons are displayed on all branch details pages
  - buttons:
      - name: Button Name 4

        event: web_trigger_four

Currently, only custom buttons on the branch details page are supported. The key in yaml is branch, and the value is in array format. The array elements are defined as follows:

• reg: Optional, String, regular expression used to match branch names (only matched branches display custom buttons configured in buttons), if not filled, matches all branches
• buttons: Required, Array<Button>, custom button definition. Button type is defined as follows
  • name: Required, String, custom button name
  • description: Optional, String, button description. If exists, it will be used as the pipeline title, otherwise the pipeline will use the default title
  • event: Required, String, event name
  • env: Optional, Object<String, String|EnvType>, default environment variables passed to the web_trigger custom event pipeline, not editable. Object key is the environment variable name; Object value supports two formats, String and EnvType. EnvType type is defined as follows:
    • name: Required, String, environment variable alias. Not the environment variable name passed to the pipeline
    • value: Required, String, environment variable value
  • permissions: Optional, permission control, satisfying either users or roles grants permission to trigger the build (repository write permission is also required). If permissions is not configured, repository write permission is sufficient to trigger the build
    • users: Optional, Array<String>, username array. Multiple can be defined.
    • roles: Optional, Array<String>, repository role array. Multiple repository roles can be defined: owner, master(Administrator), developer, reporter, guest. Roles do not follow an upward inclusion hierarchy. For example, if only the masterrole is granted permissions, the owner—even with higher repository privileges—will not have access in this context.
  • inputs: Optional, Object<String, Input>, manually input environment variables, object key is the variable name, Input type is defined as follows:
    • description: Optional, String, description
    • required: Optional, Boolean, whether required
    • type: Optional, String, input type, can be input, textarea, select, switch, default is input
    • default: Optional, String, default value
    • multiple: Optional, Boolean, whether to support multiple selection, only valid when type=select, multiple results are separated by semicolons. Commas should be avoided in the value of individual options
    • options: Optional, Array<Option>, options when type: select or type: switch. Option type is defined as follows:
      • name: Required, String, option name
      • value: Required, String, option value, used as environment variable value
      • description: Optional, String, option description

Custom web_trigger Pipeline

The custom buttons in .cnb/web_trigger.yml only support triggering web_trigger events.

The web_trigger event pipeline is configured in .cnb.yml

# .cnb.yml

# Match branch names starting with release
release*:
  # Events that can be triggered by custom buttons
  web_trigger_one:
    - stages:
        - name: Output Environment Variables
          script:
            - echo $a
            - echo $b
            - echo $var1
            - echo $var2
            - echo $var3

# Match branch names starting with dev
dev*:
  web_trigger_two:
    - stages:
        - name: Execute Task
          script: echo "job"

  web_trigger_three:
    - stages:
        - name: Execute Task
          script: echo "job"

# Match all branch names
"**":
  web_trigger_four:
    - stages:
        - name: Execute Task
          script: echo "job"

Permission Description

Only users with repository write permission can click custom buttons to execute web_trigger pipelines.
