With regular native Docker on Mac, without minikube, I can take the official example from https://docs.docker.com/engine/admin/volumes/volumes/#start-a-container-with-a-volume
run:
docker run -d \
-it \
--name devtest \
--mount source=myvol2,target=/app \
nginx:latest
Then I can run docker inspect devtest
and see that the mount was created:
"Mounts": [
{
"Type": "volume",
"Name": "myvol2",
"Source": "/var/lib/docker/volumes/myvol2/_data",
"Destination": "/app",
"Driver": "local",
"Mode": "",
"RW": true,
"Propagation": ""
}
],
I can run docker volume ls
and see myvol2
If I am using the latest minikube, currently v0.22.3, with a fresh minikube local VM:
minikube delete
rm -rf ~/.kube
rm -rf ~/.minikube
minikube start
Starting local Kubernetes v1.7.5 cluster...
Then use the minikube VM version of Docker with eval $(minikube docker-env)
, then repeat the same command from earlier:
docker run -d \
-it \
--name devtest \
--mount source=myvol2,target=/app \
nginx:latest
Then docker inspect devtest
comes back with an empty mounts section: "Mounts": []
. and docker volume ls
shows no myvol2
. In other words, the Docker volumes seem to simply not work with minikube.
FYI, here is the output of docker version
when working with Minikube v0.22.3:

https://github.com/kubernetes/minikube/issues/3001#issuecomment-446055883 may be the answer. Volume should be in minikube env in this case.
