A summarization about missing init in docker:

For unknown reasons, some docker packages are missing the init binary /usr/bin/docker-init. This is at least true for openSUSE, fedora, CentOS and deepin. This is a bug in docker package and should be reported to the distribution package maintainers. docker run --help shows option --init, but it fails.

My installation from docker repository shows:

$ docker --version
Docker version 18.03.1-ce, build 9ee9f40
$ docker-init --version
tini version 0.13.0 - git.949e6fa
$ docker run --help | grep " --init"
    --init        Run an init inside the container that forwards signals and reaps processes

tini is available on github: https://github.com/krallin/tini docker uses the statically linked https://github.com/krallin/tini/releases/download/v0.13.0/tini-static

Current solutions to get tini in container if docker run option --init fails:

Installing tini in image and using it as ENTRYPOINT: tini installation instructions for Docker images
With x11docker: Downloading a tini-static version and storing it at one of
- ~/.local/bin/x11docker (current user only)
- /usr/local/x11docker (system wide)
Latest tini-static is version 0.18.0: https://github.com/krallin/tini/releases/download/v0.18.0/tini-static
Maybe it is possible to manually install tini-static as /usr/bin/docker-init. Maybe docker will recognize and use it. But even better the distribution packages should be fixed.
