kid The path /var/lib/kubelet/ is not shared

Running OS X El Capitan && Docker for Mac 1.12.

Upon ./kid up I always get

Docker for Mac detected
docker: Error response from daemon: Mounts denied:
The path /var/lib/kubelet/
is not shared from OS X and is not known to Docker.
You can configure shared paths from Docker -> Preferences... -> File Sharing.
See https://docs.docker.com/docker-for-mac/osxfs/#namespaces for more info.
..
Waiting for Kubernetes cluster to become available...

until I SIGINT.

But in the "File Sharing" tab in Docker for Mac preferences the directory /private is already set and /var in OS X is a symlink to /private/var, so whatever kid needs in there should be shared already.

$ ls -l /
...
lrwxr-xr-x@  1 root  wheel    11 Mar 12 10:38 var -> private/var

Adding the subdirectory kubelet did not help. Adding the path /var/lib/kubelet to the File Sharing preferences is not possible since it resolves to /private/var/lib/kubelet (because of the symlink) and then overlaps with the /private share:

What to do?

Seems this is a general Docker for OSX issue. Any pointers welcome though, after an hour of googling and reading I'm still at a loss.

I have similar problems. I have changed the paths for the volume mounting for the kublet docker container in the kid script to find both the kublet and docker locations.
I get a bit further but it does not find the docker daemon.

-        --volume=/var/lib/docker/:/var/lib/docker:rw \
-        --volume=/var/lib/kubelet/:/var/lib/kubelet:rw,shared \
+        --volume="/Users/YOUR_USER/Library/Group Containers/group.com.docker/bin/docker":/var/lib/docker:rw \
+        --volume=/private/var/lib/kubelet:/var/lib/kubelet:rw,shared \

Changing the path in the kid script to

+        --volume=/private/var/lib/kubelet/:/var/lib/kubelet:rw,shared \

and creating that directory with permissions 777 makes the "is not shared" error go away.

But then I get

$ ./kid up
Docker for Mac detected
docker: Error response from daemon: mkdir /private: file exists.
Waiting for Kubernetes cluster to become available...

and that's it.

@onekilo79 do you have Docker for Mac installed (not the old Docker Toolbox)? If not, try it. Also what your tried above, mapping the docker binary to /var/lib/docker in the Moby VM, cannot be right.

I tried both. I never got this project to start with anything.

I also never got the minikube with a running k8s app either.

Aug 04 '16 10:08 onekilo79

I did get a minikube 0.7.1 session up and running using mac non-beta client 1.12.1 and using the dvm Docker version manager to downgrade docker client to 1.11.1. Do not use the docker-env settings from minikube.

Ah, running into this, too. Shoot.

Changed host path to /private/var/lib/kubelet as suggested by @nem75 but getting the somewhat cryptic error:

docker: Error response from daemon: linux mounts: Path /private/var/lib/kubelet is mounted on /private but it is not a shared mount..

I am getting this issue as well, with current master (ie, post #15 as it's at 1.3.5 now)

I'd call this really a docker bug, fwiw, that it de-references symlinks, but :-/

+1 Having the same issue any luck with this?

Sep 03 '16 14:09 mamluka

same here +1

+1 to this issue. targeting /var/log since the containers should also be compatible with gnu/linux distributions - but ofcourse, osx's /var is just a symlink.
