Motivation
The integration with docker in Flink is currently addressed in many places which often intersect, repeat each other or apply different approaches. This makes it really hard to follow the whole topic for users and maintainers. This FLIP suggests how to unify this topic. It means having one place which has the Dockerfile, all necessary scripts and docs following each other in a consistent way without any repetitions or contradictions.
...
- flink-container/kubernetes relies on flink-container/docker
- Kubernetes standalone job doc example relies on flink-container/docker
- Kubernetes standalone session doc example relies on apache/flink-docker image
- Native kubernetes integration relies on apache/flink-docker image
- Flink helm example is based on Kubernetes standalone session doc example and relies on apache/flink-docker image
- e2e tests rely on build scripts from flink-contrib/docker-flink and flink-container/docker in common_docker.sh
There are also custom Dockerfiles for tests and development purposes. This FLIP keeps them out of scope of this effort.
...
The idea is to keep all docker related resources in apache/flink-docker. It already has a detailed Dockerfile which is well suited for common use cases or at least serves as a good starting point. The suggestion is to make it extensible for other concerns which are currently addressed in other places. This mainly means refactoring of the existing code and introducing more docs as a first step. This effort should enable further improvements and follow-ups for the docker integration with Flink.
This would subsequently mean to adjust all other places to rely on or refer to apache/flink-docker code or docs. Eventually, all other purely docker related places can be completely removed: flink-contrib/docker-flink, flink-container/docker and docs/ops/deployment/docker.md.
