linux安装containerd和nerdctl

目前nerdctl最新版是2.0.0-rc.1, containerd 2.0

nerdctl-full-2.0.0-rc.1中包含了containerd 2.0,cni, nerdctl,所以直接下载这个包即可，如果nerdctl有更新，可以把以下代码中的2.0.0-rc.1替换为对应版本号即可

对于root用户

wget https://mirror.ghproxy.com/https://github.com/containerd/nerdctl/releases/download/v2.0.0-rc.1/nerdctl-full-2.0.0-rc.1-linux-amd64.tar.gz
tar Cxzvf /usr/local nerdctl-full-2.0.0-rc.1-linux-amd64.tar.gz
cp /usr/local/lib/systemd/system/*.service /etc/systemd/system/
systemctl enable buildkit containerd
systemctl start buildkit containerd

 

对于非root用户

wget https://mirror.ghproxy.com/https://github.com/containerd/nerdctl/releases/download/v2.0.0-rc.1/nerdctl-full-2.0.0-rc.1-linux-amd64.tar.gz
sudo tar Cxzvf /usr/local nerdctl-full-2.0.0-rc.1-linux-amd64.tar.gz
containerd-rootless-setuptool.sh install

如果提示exec: "newuidmap": executable file not found in $PATH. 则需要安装uidmap

 

注意，这个rootless-setuptool目前不支持centOS 7及其以下。

 

完成后nerdctl的使用方法就和docker基本一致

nerdctl compose与docker-compose 用法基本一致
