Run minikube

Run minikube in macOS(10.13.6)

install minikube

Please follow this tutorial

$ minikube version

minikube version: v0.33.1

install vm driver

I used hyperkit

1. Prepare docker images dependended and Start minikube

Run docker pull the following images on Host terminal:

	k8s.gcr.io/kube-apiserver:v1.13.2
	k8s.gcr.io/kube-controller-manager:v1.13.2
	k8s.gcr.io/kube-scheduler:v1.13.2
	k8s.gcr.io/kube-proxy:v1.13.2
	k8s.gcr.io/pause:3.1
	k8s.gcr.io/etcd:3.2.24
	k8s.gcr.io/coredns:1.2.6

Save the images as k8s.zip:

$ docker save \
	k8s.gcr.io/kube-apiserver:v1.13.2 \
	k8s.gcr.io/kube-controller-manager:v1.13.2 \
	k8s.gcr.io/kube-scheduler:v1.13.2 \
	k8s.gcr.io/kube-proxy:v1.13.2 \
	k8s.gcr.io/pause:3.1 \
	k8s.gcr.io/etcd:3.2.24 \
	k8s.gcr.io/coredns:1.2.6 \
	| gzip -c > k8s.zip

After then, run the following commands:

$ sudo rm /var/db/dhcpd_leases # before you remove it, try 'cat /var/db/dhcpd_leases'
$ minikube stop
$ minikube delete
$ minikube start --vm-driver=hyperkit -v=9

1.1 fail to download ios

Download minikube-v0.33.1.iso and move it into ~/.minikube/iso/ path.

1.2 hang on downloading kubeadm and kubectl

Retry minikube start --vm-driver=hyperkit -v=9 some times.

2. When terminal prints Starting cluster components...

We will start a simple HTTP server in Host by:

$ python -m SimpleHTTPServer

to serve k8s.zip which will be downloaded in vm.

3. Login the vm

$ ssh docker@$(minikube ip) # using password "tcuser"

The /mnt/vda1 has enough space to save k8s.zip, run the following commands:

$ cd /mnt/vda1
$ sudo wget 'http://host_ip:8000/k8s.zip' # (in my case host ip was 192.168.64.3 but you will have to connect to 192.168.64.1)
$ docker load < k8s.zip
$ sudo rm k8s.zip
$ docker images

• If meet the error: starting cluster: kubeadm init error, run following command in vm:

$ sudo kubeadm reset
$ sudo /usr/bin/kubeadm init --config /var/lib/kubeadm.yaml --ignore-preflight-errors=DirAvailable--etc-kubernetes-manifests --ignore-preflight-errors=DirAvailable--data-minikube --ignore-preflight-errors=Port-10250 --ignore-preflight-errors=FileAvailable--etc-kubernetes-manifests-kube-scheduler.yaml --ignore-preflight-errors=FileAvailable--etc-kubernetes-manifests-kube-apiserver.yaml --ignore-preflight-errors=FileAvailable--etc-kubernetes-manifests-kube-controller-manager.yaml --ignore-preflight-errors=FileAvailable--etc-kubernetes-manifests-etcd.yaml --ignore-preflight-errors=Swap --ignore-preflight-errors=CRI

• Check the log in vm

$ sudo journalctl -xeu kubelet

4. Check k8s node

$ kubectl version

will display log in termina:

Client Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.3", GitCommit:"721bfa751924da8d1680787490c54b9179b1fed0", GitTreeState:"clean", BuildDate:"2019-02-04T04:48:03Z", GoVersion:"go1.11.5", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.2", GitCommit:"cff46ab41ff0bb44d8584413b598ad8360ec1def", GitTreeState:"clean", BuildDate:"2019-01-10T23:28:14Z", GoVersion:"go1.11.4", Compiler:"gc", Platform:"linux/amd64"}

and

$ kubectl get nodes

will display log in termina:

NAME       STATUS    ROLES     AGE       VERSION
minikube   Ready     master    17m       v1.13.2

Have fun with k8s!
