- docker查看创建的内部网段的信息
docker network inspect net1
- docker移除创建的内部网段
docker nerwork rm net1
- docker私服Harbor搭建
- 登录阿里云镜像仓库
docker login --username=username registry.cn-hangzhou.aliyuncs.com
- 推送镜像到阿里云镜像仓库
docker tag nginx registry.cn-hangzhou.aliyuncs.com/pascall/nginx
docker push registry.cn-hangzhou.aliyuncs.com/pascall/nginx
