安装container和nerdctl和buildkit

https://blog.csdn.net/omaidb/article/details/128677718

buildkit项目地址：https://github.com/moby/buildkit
nerdctl 也可以和 buildkit 结合使用来构建容器镜像。

使用nerdctl构建docker镜像

参考:

修改Dockerfile

https://blog.csdn.net/omaidb/article/details/121434775

构建镜像

# 构建镜像
./Dockerfile |nerdctl build -t 镜像名:tag

# 构建镜像
nerdctl build -t 镜像名:tag .

# 查看构建好的镜像
nerdctl images

containerd配置代理

老是替换源太麻烦了,直接上代理
https://segmentfault.com/a/1190000020363043

# 创建/etc/systemd/system/containerd.service.d目录
mkdir /etc/systemd/system/containerd.service.d

# 配置代理
cat > /etc/systemd/system/containerd.service.d/proxy.conf << EOF
> [Service] 
> Environment="HTTP_PROXY=socks5://127.0.0.1:1080" 
> Environment="HTTPS_PROXY=socks5://127.0.0.1:1080"  "NO_PROXY=localhost,127.0.0.1,192.168.0.0/16,10.0.0.0/8,docker-registry.somecorporation.com,isdp30x2.mirror.aliyuncs.com,hub-mirror.c.163.com,mirror.baidubce.com"'
> EOF

# 重启containerd服务
systemctl daemon-reload
systemctl restart containerd

# 查看配置的代理
systemctl show --property=Environment containerd.service
