Configure your shell to use docker daemon of Minishift eval $(minishift docker-env) export user token registry URL export TOKEN=$(oc whoami -t) export REGISTRY_URL=$(minishift openshift registry) Logging in to Registry docker login -u developer -p $TOKEN $REGISTRY_URL OR we can use directly as, docker login -u developer -p $(oc whoam -t) $(minishift openshift registry) Now you can tag images, push it to respective project to create imagestream docker tag mynodejs $(minishift openshift registry)/myproject/nodejs Push the docker image to registry so that it will create imagestream automatically, docker push $(minishift openshift registry)/myproject/nodejs Now you can create application using the new imagestream, oc new-app --image-stream=nodejs --name app

supports PV of type hostpath. minikube is configured to persist files stored under following directories. /data /var/lib/localkube /var/lib/docker /tmp/hostpath_pv /tmp/hostpath-provisioner any other directory will not persist the data after reboot. To mount host directory inside minikube, $ minikube mount /host-mount-path:/vm-mount-path for example, $ minikube mount ~/mount-dir:/mountexample Mounting /home/user/mount-dir/ into /mountexample on the minikubeVM This daemon process needs to stay alive for the mount to still be accessible... ufs starting This process has to stay open, so open another terminal (if you want more than one mountpath, open one more terminal follow the above procedure)...
