拉取上传镜像

拉取镜像

docker pull <registry>[:<port>]/[<namespace>/]<name>:<tag>
# registry  :仓库服务器地址;不指定默认是docker hub
# port      :端口;默认443,因为是https协议;
# namespace :名称空间,指是哪个用户的仓库,如果是顶层仓库,可以省;
# name      :仓库名;
# tag       :标签名;默认是latest版本;

上传镜像

docker push [OPTION]NAME[:TAG]

搭建私有仓库distribution

docker 提供的开源registry,只能作为存储镜像的仓库,没有额外的功能(比如管理页面等);

# 拉取镜像
[root@localhost ~]# docker pull registry
Using default tag: latest
latest: Pulling from library/registry

# 启动registry容器
[root@localhost ~]# docker run -d --name registry -p 5000:5000 -v /data/registry:/var/lib/registry registry:latest

从私有仓库上传下载镜像

# 给本地仓库打上合适的标签
[root@localhost ~]# docker tag busybox:latest 192.168.100.61:5000/busybox:v0.1
[root@localhost ~]# docker images

# 上传镜像(失败原因:docker上传下载默认只支持https协议,搭建的私有仓库是http协议
[root@localhost ~]# docker push 192.168.100.61:5000/busybox:v0.1
The push refers to repository [192.168.100.61:5000/busybox]
Get https://192.168.100.61:5000/v2/: http: server gave HTTP response to HTTPS client

# 将私有仓库认证为安全仓库,重启
[root@localhost ~]# vim /etc/docker/daemon.json
{
  "registry-mirrors": ["https://xxxxxx.mirror.aliyuncs.com"],    # 这个是我的阿里云镜像加速器地址
  "insecure-registries": ["192.168.100.61:5000"]
}
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker

# 再次上传镜像
[root@localhost ~]# docker push 192.168.100.61:5000/busybox:v0.1
