Personal lab (with notes) - minikube with docker
-
date: Mon Oct 24 11:52:09 HST 2016
-
my environment:
- mac
- docker for mac installed, configured, and running
- configured
~/.docker/config.jsonfor public and private images - using mac xhyve
- no VPN running, no proxy needed
- editor:
- atom (w yamlLint)

install
install driver
$ brew install docker-machine-driver-xhyve
# docker-machine-driver-xhyve need root owner and uid
$ sudo chown root:wheel $(brew --prefix)/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve
$ sudo chmod u+s $(brew --prefix)/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve
start minikube with xhyve
# minikube --vm-driver=xxx start
$ minikube --vm-driver=xhyve start
# minikube-start alias
$ echo "alias minikube-start='minikube --vm-driver=xhyve start'" >> ~/.basrhc
or place the config in minikube
$ minikube config set vm-driver xhyve
$ minikube stop
$ minikube start
issues with starting
# just in case - moving .kube out
mv .kube .kube-nbcu-latest/
woohoo - works
$ minikube --vm-driver=xhyve start
Starting local Kubernetes cluster...
Kubectl is now configured to use the cluster.
$ kubectl cluster-info
Kubernetes master is running at https://192.168.64.7:8443
kubernetes-dashboard is running at https://192.168.64.7:8443/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
intersesting - the install does create a .kube and .minikube
