安装containerd
sudo apt install containerd
从https://github.com/containernetworking/plugins的release中下载最新的cni插件二进制文件，放入/opt/cni/bin
在/etc/cni/net.d下创建文件10-containerd-net.conflist
内容为
{
“cniVersion”: “1.0.0”,
“name”: “containerd-net”,
“plugins”: [
{
“type”: “bridge”,
“bridge”: “cni0”,
“isGateway”: true,
“ipMasq”: true,
“promiscMode”: true,
“ipam”: {
“type”: “host-local”,
“ranges”: [
[{
“subnet”: “10.88.0.0/16”
}],
[{
“subnet”: “2001:4860:4860::/64”
}]
],
“routes”: [
{ “dst”: “0.0.0.0/0” },
{ “dst”: “::/0” }
]
}
},
{
“type”: “portmap”,
“capabilities”: {“portMappings”: true}
}
]
}
注：目前以非root用户直接运行kubelet/tests/pod_create_test会出错，需要将/run/containerd/containerd.sock设为当前用户可读写
可以使用指令 sudo chmod a+rw /run/containerd/containerd.sock
