how to use the variable send through a trigger bitbucket pipeline in the triggered pipeline?

[Marine Chaput]

Hi,

 I am trying to trigger a pipeline in my doc repository when a release is done in my actual code repository. For this, I am following the example given in "trigger bitbucket pipeline".

What I don't understand is how to write the pipeline which will be triggered in the other side and how use the variable send by the release pipeline ?

Thank you

You're variables will be available in your triggered pipeline as environment variables. For example, if you write your release pipeline like the following:

script:
  - pipe: atlassian/trigger-pipeline:4.0.5
    variables:
      BITBUCKET_USERNAME: $BITBUCKET_USERNAME
      BITBUCKET_APP_PASSWORD: $BITBUCKET_APP_PASSWORD
      REPOSITORY: 'your-awesome-repo'
      BRANCH_NAME: 'master'
      CUSTOM_PIPELINE_NAME: 'deployment-pipeline'
      PIPELINE_VARIABLES: >
          [{
            "key": "AWS_DEFAULT_REGION",
            "value": "us-west-1"
          },
          {
            "key": "AWS_ACCESS_KEY_ID",
            "value": "$AWS_ACCESS_KEY_ID",
            "secured": true
          },
          {
            "key": "AWS_SECRET_ACCESS_KEY",
            "value": "$AWS_SECRET_ACCESS_KEY",
            "secured": true
          }]
      WAIT: 'true'

You can use AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_DEFAULT_REGION in your downstream pipeline like this:

pipelines:
  default:
    - step:
        script:
        - echo $AWS_ACCESS_KEY_ID
        - echo $AWS_SECRET_ACCESS_KEY
        - echo $AWS_DEFAULT_REGION

Thank you. I was thinking by putting the custom pipeline name as 'deployment-pipeline, i need to have a downstream pipeline like this : 

pipelines:
  custom:
    deployment-pipeline:
        - step:
           script:
              - echo $AWS_ACCESS_KEY_ID
              - echo $AWS_SECRET_ACCESS_KEY
              - echo $AWS_DEFAULT_REGION

I have a still an error when the pipeline is triggered.

Do you have an idea what it could be ?

HttpResponseSummary{httpStatusCode=400, httpStatusMessage=Bad Request, bodyAsString={"key":"variable-service.request.validation-error","message":"The request body contains invalid properties","arguments":{"value.required":"Property value is required"}}} (command VARIABLE_SERVICE_CREATE_PIPELINE_VARIABLE, error key='variable-service.request.validation-error')

Thanks you for your answer

You're probably missing a variable value. Note, that there are two fields for each variable: key, which is a variable name, and value, which is an actual variable value.

{
    "key": "VariableName",
    "value": "VariableValue"
}
