2)发布到自己的仓库

docker仓库构建

实验准备： 一台服务器 一台客户端
1.自定义仓库

1）自定义仓库配置

注意 这个配置文件里边的ip地址和下边的Ip地址要一致 都写服务器的ip地址

  1. docker run -d -v /opt/registry:/var/lib/registry -p 5000:5000 --restart=always registry
  2. # 开启官方镜像仓库设置 端口开机自启动  默认是443端口 我们的客户端认为不安全 就需要下边这个配置文件 让客户端觉得安全
  3. vim /etc/docker/daemon.json
  4. {
  5. "insecure-registries": ["192.168.88.10:5000"]
  6. }
  7. systemctl restart  docker   # 重启
  8. docker ps -a  # 查看

2）上传

上传格式 仓库地址/Username/ImageName:tar
docker push 仓库地址/Username/ImageName:tar
例子：docker push 192.168.88.10:5000/tomcat:v1``.``0

3）查看

curl  -XGET http://192.168.88.10:5000/v2/_catalog  #查看已有镜像

4）客户端配置

vim /etc/docker/daemon.json
{
"insecure-registries": ["192.168.88.10:5000"]
}
systemctl restart  docker   # 重启
docker ps -a  # 查看
curl  -XGET http://192.168.88.10:5000/v2/_catalog  #查看已有镜像

5）从仓库下载

docker pull 192.168.88.10:5000/tomcat:v1.0

2.harbor 仓库
都在文档里自己看
