1.在原有的docker服务基础上，下拉一个  镜像：

docker pull registry:2.6.2

2.运行：

docker run -d -p 5000:5000 --restart=always --name registry registry:2.6.2

 3.将自己的镜像推送到私有仓库：

    例如：docker.io/langwanghuangshifu/eureka-server:latest

docker push localhost:5000/langwanghuangshifu/eureka-server:latest

    运行提示：

    The push refers to a repository [localhost:5000/langwanghuangshifu/eureka-server]    An image does not exist locally with the tag: localhost:5000/langwanghuangshifu/eureka-server

    此时，会发现推送失败，由于docke hub 为默认的镜像仓库，推送命令实质上为：docker push docker.io/langwanghuangshifu/eureka-server:latest

    因此需要将上述镜像更改镜像标签:

docker tag langwanghuangshifu/eureka-server:latest localhost:5000/langwanghuangshifu/eureka-server:latest

    再次执行：

docker push localhost:5000/langwanghuangshifu/eureka-server:latest

    推送成功：

4.查看私有仓库的镜像：

• 镜像列表：

[root ~]# curl http://localhost:5000/v2/_catalog

{"repositories":["langwanghuangshifu/eureka-server"]}

 

• 具体某个镜像的标签列表：

    curl http://localhost:5000/v2/镜像名/tags/list

        例如：langwanghuangshifu/eureka-server

[root ~]# curl http://localhost:5000/v2/langwanghuangshifu/eureka-server/tags/list

{"name":"langwanghuangshifu/eureka-server","tags":["latest"]}
