Pipeline : Generate a unique name for each pipeline

[James St-Pierre]

In our BitBucket Pipeline we must provide a variable to `pipe: atlassian/aws-elasticbeanstalk-deploy:0.3.0` that must be unique everytime.

What we are currently using :

- step:
    name: Deploy to AWS
    deployment: production-aws
    image: atlassian/default-image:2
    script:
      - pipe: atlassian/aws-elasticbeanstalk-deploy:0.3.0
        variables: 
          ...
          VERSION_LABEL: "name.$BITBUCKET_BUILD_NUMBER-bitbucket"

We currently have an issue : if the step fails and we use "Retry only failed steps", the $BITBUCKET_BUILD_NUMBER is not incremented. This is causing an error on our end because the "VERSION_LABEL" is already in use.

Is there another way to generate a unique version label?

Thank you !

Hi @James St-Pierre

I'm not sure if there is an easy way to identify if a build is rerun in pipelines, but what you could use in your label is a Linux timestamp. You could create a variable and use it in your label to distinguish builds based on the time the ran.

This would be the way to create the variable

script:
      - TIMESTAMP=`date +%s`
      - pipe: atlassian/aws-elasticbeanstalk-deploy:0.3.0
        variables: 
          ...
          VERSION_LABEL: "name.$BITBUCKET_BUILD_NUMBER-$TIMESTAMP-bitbucket"

I hope that is a possible solution for this issue.
