New version of docker desktop on macos and /var/run/docker.sock

[cmoulliard]

Issue

With the new version of docker desktop on macos, the sock file located historically under /var/run/docker.sock don't exist anymore and has been replaced by a sock created under ~/Library/Containers/com.docker.docker/Data/docker.raw.sock /var/run/docker.sock

To by pass this issue, create a symbolic link as described here : https://stackoverflow.com/questions/44084846/cannot-connect-to-the-docker-daemon-on-macos

sudo ln -s ~/Library/Containers/com.docker.docker/Data/docker.raw.sock /var/run/docker.sock
ls -la /var/run/docker.sock
lrwxr-xr-x@ 1 root  daemon  73 Nov 20 10:03 /var/run/docker.sock@ -> /Users/cmoullia/Library/Containers/com.docker.docker/Data/docker.raw.sock

And to be sure that the java builder will use it, set the following parameter

            .withNewDockerConfig()
              .withDockerHost("unix:///var/run/docker.sock")
            .endDockerConfig()
