containerd配置

生成默认配置

# containerd config default > /etc/containerd/config.toml

修改默认配置文件:

sandbox_image = "docker.io/w564791/pause:3.1"

• containerd默认是去Google仓库拉镜像,所以在使用时,最后加上镜像仓库地址

containerd.service配置

[Unit]

[Service]
Type=simple
ExecStart=/bin/bash -c "GOMAXPROCS=$(nproc) /usr/local/bin/containerd"
Restart=always
[Install]
WantedBy=multi-user.target

使用crictl 命令
