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 
version: 0.1
log:fields:service: registry
storage:cache:layerinfo: inmemoryfilesystem: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
REPOSITORY                                           TAG         IMAGE ID       CREATED         SIZE
mysql                                                5.6         dd3b2a5dcb48   20 months ago   303MB
registry.cn-hangzhou.aliyuncs.com/su03/mycontainer   mysql_5.6   dd3b2a5dcb48   20 months ago   303MB
centos                                               latest      5d0da3dc9764   23 months ago   231MB
registry                                             2.6.2       10b45af23ff3   3 years ago     28.5MB
owncloud                                             latest      327bd201c5fb   4 years ago     618MB[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]
74ddd0ec08fa: Pushed

total 0
drwxr-xr-x 5 root root 55 Aug 25 17:30 centos

4.拉取镜像

[root@localhost ~]# docker pull 192.168.2.190:5000/centos:latest 
latest: Pulling from centos
Digest: sha256:a1801b843b1bfaf77c501e7a6d3f709401a1e0c83863037fa3aab063a7fdb9dc

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 
a2ddb1f22601398d13dcfcc2f6e495883d5b9cf52fce690eefbe8d0cfc787fd0[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

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