【microk8s 1】ubuntu20.04 snap安装docker

参考 之前装过一次，好像镜像代理有问题，找找资料，重新试试。 microk8s 获取节点成员

root@k8s-master-2K4G:~# microk8s kubectl get nodes
NAME              STATUS   ROLES    AGE   VERSION
k8s-master-2k4g   Ready       19d   v1.22.4-3+adc4115d990346

snap 安装docker

root@k8s-master-2K4G:~# sudo snap install docker
error: cannot install "docker": Post https://api.snapcraft.io/v2/snaps/refresh: proxyconnect tcp:
       dial tcp 127.0.0.1:7890: connect: connection refused
root@k8s-master-2K4G:~# 

我好像是用了snap 的代理 配置： 启动代理
