* [EXPOSE](https://docs.docker.com/engine/reference/builder/#expose) informs Docker that the container listens on the specified network ports at runtime. NOTE: does not actually make ports accessible.
* [ENV](https://docs.docker.com/engine/reference/builder/#env) sets environment variable.
* [ADD](https://docs.docker.com/engine/reference/builder/#add) copies new files, directories or remote file to container. Invalidates caches. Avoid `ADD` and use `COPY` instead.
* [COPY](https://docs.docker.com/engine/reference/builder/#copy) copies new files or directories to container. Note that this only copies as root, so you have to chown manually regardless of your USER / WORKDIR setting, as same as `ADD`. See <https://github.com/moby/moby/issues/30110>
* [COPY](https://docs.docker.com/engine/reference/builder/#copy) copies new files or directories to container. By default this copies as root regardless of the USER/WORKDIR settings. Use `--chown=<user>:<group>` to give ownership to another user/group. (Same for `ADD`.)
* [ENTRYPOINT](https://docs.docker.com/engine/reference/builder/#entrypoint) configures a container that will run as an executable.
* [VOLUME](https://docs.docker.com/engine/reference/builder/#volume) creates a mount point for externally mounted volumes or other containers.
* [USER](https://docs.docker.com/engine/reference/builder/#user) sets the user name for following RUN / CMD / ENTRYPOINT commands.
