docker-compose build --pull breaks dependent builds within same compose file

[solsson]

After 1602ed4 and 078eeea we can no longer run compose files with the following convention:

  productionimage:
    build:
      context: ../
    image: registry/yolean/something
  testservice:
    depends_on:
      - httpd-latest
    build:
      # This dockerfile has "FROM registry/yolean/something"
      context: ../modify-for-testing

An example such build is https://github.com/Reposoft/docker-svn/blob/master/build-contracts/docker-compose.yml where production image builds have local dependencies.

Is it possible to do these modifications through environment variables and/or build args?

[solsson]

Maybe. Those services that depend on a local build will never need pull.

I guess we ruled out use of tags based on https://medium.com/@mccode/the-misunderstood-docker-tag-latest-af3babfd6375#.sv5ir95x1
