    Description

    Enabled

    By enabling the function, you can set options by configuring APIs.

    Linked Attribute

    URL

    Only HTTPS protocol is supported.

    Returned Data Path

    The widget used must be list data. In the following response body example, the returned data path is result.parameters.

    {
        "result": {
            "total": 2,
            "parameters": [
                {

                    "name": "parameters02"
                }
            ]
        },
        "status": "success"
    }

    Option Value

    Set this parameter to the value of the corresponding field in the returned data path. This parameter is delivered when the extension is running.

    Option Name

    Set this parameter to the value of the corresponding field in the returned data path. This parameter is displayed on the extension configuration page.

    Params

    Params parameters of the API request body.

    Header

    Header parameters of the API request body.

    Remote Search

    Enable this function to add a remote search field. For extension search, the entered value will be used as the value of the remote search field to call the API again.

    • Params parameter: The parameter type of the search field is the Params parameters of the API request body.
    • Body parameter: The parameter type of the search field is the Body parameters of the API request body.

  7. Click Next. On the displayed Orchestration page, you can add the ExecuteShellCommand extension.

    • ExecuteShellCommand: execute shell commands entered by users.

      Enter shell commands. Commands will be executed when a pipeline call the extension.

      The commands indicate the actual service logic implementation process of an extension. For more input and output configurations, see Customizing Shell Commands.

  8. Click Next. On the displayed page, click Add Configuration to configure output or metric information.

    • output: output data together with shell commands.
    • metric: output metric thresholds. The thresholds information can be referenced in an extension and finally applied to pipelines.

  9. After the configuration, click Release or Release Draft.

    • Draft release
      Click Release Draft to release a test version.
      • You can configure a draft extension in a pipeline for debugging. After debugging, the draft extension can be officially released, so that other members of the current tenant can use the extension.
      • All draft versions are marked with Draft.
      • Only one draft is allowed. If there is already a draft, no more versions can be created until you officially release or delete the draft.
    • Official release

      Click Release to release an official version. An official extension has a unique version number. All members of the current tenant can use this version in a pipeline.

Customizing Shell Commands

When registering an extension or creating an extension version, you can use shell commands to implement service logic. The commands usually involve interaction with all kinds of data during pipeline execution. This section describes how to implement extension logic through data input and output.

  • Data Input

    The obtained data consists of low-code GUI input, pipeline run parameters, and other information.

    • Low-code GUI input: Obtain the low-code user interface output by using environment variables, for example, echo ${Widget ID}.
    • Pipeline run parameters: Some pipeline run parameters will be delivered to environment variables as shown in the following table.
      Table 4 Pipeline environment variables

      Variable

      Description

      STEP_NAME

      Step name of the pipeline.

      STEP_ID

      Step ID of the pipeline.

      PLUGIN_VERSION

      Version of the extension.

      PIPELINE_ID

      Pipeline ID.

      PIPELINE_RUN_ID

      Pipeline execution ID.

      PLUGIN_NAME

      Extension name.

      PROJECT_ID

      Project ID.

      JOB_ID

      Job ID of the pipeline.

    • Other information: Obtain information by interacting with external data through Git, Wget, and Curl.
  • Data Output

    Once executed, the custom extension can read file information in a specified path and obtain the metric data output.

    1. On the configuration page, configure the thresholds output of the extension.
    2. During development, the ${STEP_ID}_result.json and ${STEP_ID}_metrics.json files are stored in a specified path so that metric values can be parsed.
      Table 5 Output files

      File

      Description

      ${RESULT_MSG_PATH}/${STEP_ID}_result.json

      The output is a text file in {"par1":123, "par2":456} format. After the pipeline is executed, the result will be displayed as the corresponding task result.

      NOTE:

      Only extensions of the check type can display the result.

      ${RESULT_MSG_PATH}/${STEP_ID}_metrics.json

      The output is a text file in {"par1":123, "par2":456} format. The Metrics widget should be configured. After the extension is executed, the threshold configured for the Metrics widget and the content of ${STEP_ID}_metrics.json are parsed for pipeline pass conditions. Notes:

      • During parsing, empty key values in the Metrics widget will be ignored.
      • If the key value configured for the Metrics widget cannot be found in the ${STEP_ID}_result.json file, the specified threshold value will be used.

      Example: par1 and par2 for pass conditions; par3 and par4 for task result display. The sample code is as follows:

      # Optionally, construct the extension output.
      echo '{"par1":100,"par2":200}' > ${RESULT_MSG_PATH}/${STEP_ID}_result.json
      echo '{"par3":300,"par4":400}' > ${RESULT_MSG_PATH}/${STEP_ID}_metrics.json
    3. After the extension run is complete, click the extension card to view the output.

      If policies are configured for the current extension and applied to the pipeline pass conditions, click the pass conditions to view the check status.
