I'd like to run a service in Bitbucket Pipelines, but it requires a username and password. I do not want to put these credentials into bitbucket-pipelines.yml as I don't want to commit them into the source code.

Unfortunately environment variables configured via the repository or account are not made available for services. Would it be possible to change this behavior and publish the environment variables also for the services, or offer another way for secure variables to be passed to services?
