Suppose having a project in a bitbucket repository storing a secret API key in a config file like config.json:

{
    "secret": 
}

Is it possible refer to the "secret" variable from variables in bitbucket pipeline and then deploy this automatically to google App Engine, so that App Engine "knows" the secret variable?

You can use envsubst mand in your pipeline.

Your json file would look like this and be named config_template.json:

{
    "secret": $SECRET
}

The step in your pipline would look like this:

- step:
    name: replace secret
    script:
      # pipe config_template.json to envsubst and store result in a file called config.json
      - cat config_template.json | envsubst > config.json
      # show config.json TODO: Remove this when you are sure it is working!
      - cat config.json
      # Deploy config.json to App Engine here!

This assumes that you have envsubst in your build image and a repository variable called SECRET in your pipeline.
