Sharing a unix socket between a Docker container and it's host

Raw

Build the image from the Dockerfile above:

docker build --rm -t cberg-test .

Run a container, sharing the host dir /root/foo:

docker run --rm -v /root/foo:/foo cberg-test

In another shell, write something to the socket (which was created in /root/foo by the container):

echo 'hello docker' | socat - UNIX-CONNECT:/root/foo/bar.sock

See the output of the container in the first shell:

hello docker

Raw

	FROM ubuntu

	RUN apt-get update
	RUN apt-get install -y socat

	VOLUME /foo

	CMD socat UNIX-LISTEN:/foo/bar.sock -
