选择安装包

选择这个完整版，可以连containerd一起安装。

2 安装

• 解压缩得到一下四个目录

[root@liubei-02 nerdctl-full-1.0.0]# ll
drwxr-xr-x 2 root root      4096 10月 21 21:28 bin
drwxr-xr-x 3 root root        21 10月 21 21:27 lib
drwxr-xr-x 3 root root        17 10月 21 21:27 libexec
drwxr-xr-x 3 root root        17 10月 21 21:22 share

• 拷贝二进制文件

cp ./bin/* /usr/local/bin

• 拷贝启动文件

cp -ra ./lib/systemd/system/* /etc/systemd/system/

• 启动和开机启动

# systemctl enable buildkit containerd 
# systemctl restart buildkit containerd 
# systemctl status buildkit containerd

• cni 插件

[root@liubei-02 nerdctl-full-1.2.1]# makedir /opt/cni/bin
[root@liubei-02 nerdctl-full-1.2.1]# cp -ra ./libexec/cni/* /opt/cni/bin/

3 替代docker

和docker命令几乎相同，举几常用的命令做例子
