microk8s 是一个专门为开发人员设计的轻量级单节点k8s包.可以用来替代minikube进行学习.
问题
由gfw,安装microk8s后会发现docker image无法下载的问题.(详细安装步骤参见 https://microk8s.io/#quick-start)
microk8s.kubectl describe pods -A 会有错误提示
[ERROR ImagePull]: failed to pull image [k8s.gcr.io/pause:3.1]
解决办法
docker pull mirrorgooglecontainers/pause:3.1
docker pull mirrorgooglecontainers/heapster-influxdb-amd64:v1.3.3
