Is pipelines smart enough to read the same file name in different branches and choose the right one?

unknown

Example: I want to have for different branches a Dockerfile. When I specify the branch to trigger my pipeline and run " $ docker build . " , does bitbucket pipelines understand which dockerfile should take based on the branch or do I have to declare something else in my bitbucket-pipelines file ?

Hi Aris,

Bitbucket Pipelines checks out the relevant branch for your branch pipeline configuration.

For example:

pipelines:
  branches:
    master:
      - step:
          script:
            - cat Dockerfile # Will print the Dockerfile on master branch.
    staging:
      - step:
          script:
            - cat Dockerfile # Will print the Dockerfile on staging branch.

Try it out for yourself if you want!

As an aside, if you want to have different Dockerfiles for multiple branches, it might be better (depending on your workflow) to have multiple Dockerfiles across all branches, so that your branches don't get out of sync.

pipelines:
  branches:
    master:
      - step:
          script:
            - docker build -f Dockerfile . # Will build a docker image off the Dockerfile on master branch.
    staging:
      - step:
          script:
            - docker build -f Staging-Dockerfile . # Will build a docker image off the Staging-Dockerfile on staging branch.

Then you don't need to worry about someone accidentally overwriting the Dockerfiles on different branches.

Thanks,

Phil
