配置containerd

修改镜像源

~# containerd config default > /etc/containerd/config.toml
~# sed -i "s#k8s.gcr.io/pause#registry.aliyuncs.com/google_containers/pause#g" /etc/containerd/config.toml

镜像加速

#在此行下面加两行
      [plugins."io.containerd.grpc.v1.cri".registry.mirrors]        
        [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
          endpoint = ["https://registry.aliyuncs.com","https://docker.mirrors.ustc.edu.cn", "http://hub-mirror.c.163.com"]
        [plugins."io.containerd.grpc.v1.cri".registry.mirrors."gcr.io"]
          endpoint = ["https://gcr.mirrors.ustc.edu.cn"]
        [plugins."io.containerd.grpc.v1.cri".registry.mirrors."k8s.gcr.io"]
          endpoint = ["https://gcr.mirrors.ustc.edu.cn/google-containers/"]
        [plugins."io.containerd.grpc.v1.cri".registry.mirrors."quay.io"]
          endpoint = ["https://quay.mirrors.ustc.edu.cn"]

设置cgroup驱动

~# sed -i 's#SystemdCgroup = false#SystemdCgroup = true#g' /etc/containerd/config.toml
