6. 修改docker镜像获取地址

1. 编辑docker镜像地址
vi /etc/docker/daemon.json

{
  "registry-mirrors": [
    "https://docker.m.daocloud.io"
  ]
}

2. 重启docker服务
systemctl restart docker.service

7. 查看镜像打包历史

dokcer history image-name

root@ubuntufordocker:/etc/docker# docker history hello-world
IMAGE          CREATED         CREATED BY                SIZE      COMMENT
d2c94e258dcb   16 months ago   CMD ["/hello"]            0B        buildkit.dockerfile.v0
<missing>      16 months ago   COPY hello / # buildkit   13.3kB    buildkit.dockerfile.v0
