@mxn neither `docker build` nor `docker compose build` support setting
environment variables from outside during the build. Further as the
`docker-compose` documentation states
> Note: If your service specifies a build option, variables defined in
environment will not be automatically visible during the build. Use the args
sub-option of build to define build-time environment variables.
It is only possible to give arguments to the build step of `docker-compose`
using the `--build-args` option, which can be interpolated with
`${my_env_var}`. But still requires the `Dockerfile` to use `ARG`.
Further I question the Docker version compatibility. First, flink could
provide an automated build on Docker Hub. Second, one could provide a
`Dockerfile.legacy` aswell.
