Run the docker daemon inside plash
Raw
plash-docker-daemon
#!/usr/bin/env plash-exec
--# usage: plash docker-daemon <DOCKER-ARGS>
--# Run the docker daemon inside alpine linux. Use the PLASH_DOCKER_SOCKET
--# environment variable to select the docker socket, the default is
--# '/tmp/docker.sock'. Note that '/var/run/docker.sock' is not shared between
--# containers and host, so it may not be appropriate as a socket
--#
--#
--# Example:
--#
--# $ sudo plash docker-daemon
--# INFO[2018-02-05T00:20:06.645188781Z] libcontainerd: new containerd process, pid: 19841
--# <snip>
--# INFO[2018-02-05T00:20:07.840933519Z] Daemon has completed initialization
--# INFO[2018-02-05T00:20:07.849471459Z] API listen on /tmp/docker.sock
--from
alpine
--apk
docker
--layer
--entrypoint-script
#!/bin/sh
# we need to "encapsulate" the socket. Docker creates it accesible by the docker
# group, but the gid inside the guest could be anything for the host (closes #8)
