一.distribution

1.扩展源下载docker-distribution并启动

[root@localhost ~]# yum info docker-distribution

[root@localhost ~]# yum install -y docker-distribution.x86_64

[root@localhost ~]# systemctl start docker-distribution

[root@localhost ~]# cd /etc/docker-distribution/registry/

[root@localhost registry]# cat config.yml

        layerinfo: inmemory
    filesystem:
        rootdirectory: /var/lib/registry  #默认的镜像存放大致路径
http:
    addr: :5000   #端口

2.打标签并认证安全仓库

[root@localhost ~]# docker images

[root@localhost ~]# docker tag centos:latest 192.168.2.190:5000/centos:latest

[root@localhost ~]# vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"],
"insecure-registries": ["192.168.2.190:5000"]
}

[root@localhost ~]# systemctl restart docker

3.推送到私人仓库

[root@localhost ~]# docker push 192.168.2.190:5000/centos:latest 
The push refers to repository [192.168.2.190:5000/centos]

二.registry

1.拉取registry的镜像

[root@localhost ~]# systemctl stop docker-distribution.service 

[root@localhost ~]# docker pull registry:2.6.2

2.运行容器并打标签

-v指定把镜像存储到宿主机的/registry目录下

[root@localhost ~]# docker run -itd --name myregistry -p 5000:5000 -v /registry:/var/lib/registry registry:2.6.2

[root@localhost ~]# docker tag nginx:latest 192.168.2.190:5000/nginx:latest

3.认证安全仓库

[root@localhost ~]# vim /etc/docker/daemon.json 
{
"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"],
"insecure-registries": ["192.168.2.190:5000"]
}

[root@localhost ~]# systemctl restart docker

4.推送到私人仓库
