docker镜像仓库

搭建私有镜像仓库

Docker Hub作为Docker默认官方公共镜像，如果想自己搭建私有镜像仓库，官方也提供registry镜像，使得搭建私有仓库非常简单。
下载registry镜像并启动

[root@docker ~]# docker pull registry
[root@docker ~]# docker run -d -v /opt/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry

测试查看镜像仓库中所有镜像

[root@docker ~]# curl http://192.168.193.128:5000/v2/_catalog
{"repositories":[]}

私有镜像仓库管理

配置私有仓库可信任

[root@docker ~]# cat /etc/docker/daemon.json 
{
    "registry-mirrors":["https://registry.docker-cn.com"],
    "insecure-registries":["192.168.193.128：5000"]
}
[root@docker ~]# systemctl restart docker

打标签

[root@docker ~]# docker tag nginx:1.12 192.168.193.128:5000/nginx:1.12

上传

[root@docker ~]# docker push 192.168.193.128:5000/nginx:1.12
[root@docker ~]# curl http://192.168.193.128:5000/v2/_catalog
{"repositories":["nginx"]}
查看信息
[root@docker ~]# curl http://192.168.193.128:5000/v2/nginx/tags/list
{"name":"nginx","tags":["1.12"]}

下载

[root@docker ~]# docker run -itd --name nginx -p 80:80 192.168.193.128:5000/nginx:1.12
