I am using docker-compose with multi-stage Dockerfiles to build and run multiple services. This works, but the "build" portion of each multi-stage build is largely copy-and-pasted between each service's Dockerfile. I want to reduce the copy-and-paste / centralize the common build logic in one spot.
Reading https://engineering.busbud.com/2017/05/21/going-further-docker-multi-stage-builds/ I could create a local image with the shared build steps and have the service Docker files depend on it, but I want the development experience to be a simple docker-compose up. Creating a local build image means a developer would have to know to run docker build [common_build_image] first so that the build image exists locally and THEN run docker compose up to build and run all the services that depend on it.
There doesn't appear to be a way to include a Dockerfile into another Dockerfile. FROM does not appear to support local paths.
Is there a way to accomplish what I want? Of course I can use a shell script to tie everything together, but that is basically what multi-stage builds was trying to solve in the first place.
