[root@centos79 ~]#

2.启动docker registry

命令:

mkdir -p /data/registry

docker run -itd -p 5000:5000 -v /data/registry:/var/lib/registry --name my_registry registry:latest

[root@centos79 ~]# mkdir -p /data/registry
[root@centos79 ~]# docker run -itd -p 5000:5000 -v /data/registry:/var/lib/registry --name my_registry registry:latest

[root@centos79 ~]#

3.查看运行的docker容器

命令:

docker ps | grep my_registry

netstat -antulp | grep 5000

[root@centos79 ~]# docker ps | grep my_registry
010c6b9f3935   registry:latest        "/entrypoint.sh /etc…"   18 seconds ago   Up 16 seconds   0.0.0.0:5000->5000/tcp, :::5000->5000/tcp                                              my_registry
[root@centos79 ~]# netstat -antulp | grep 5000

[root@centos79 ~]#

4.本地配置docker registry,并保存

命令:

vim /etc/docker/daemon.json

添加前:

[root@centos79 ~]# cat /etc/docker/daemon.json 
{
  "registry-mirrors": ["https://ykjpg821.mirror.aliyuncs.com"]
}
[root@centos79 ~]#

添加后:

[root@centos79 ~]# cat /etc/docker/daemon.json 
{
  "registry-mirrors": ["https://ykjpg821.mirror.aliyuncs.com"],
  "insecure-registries": ["172.20.10.12:5000"]
}
[root@centos79 ~]#

5.重启docker

命令:

systemctl reload

systemctl stop docker

systemctl start docker

systemctl status docker

[root@centos79 ~]# systemctl daemon-reload
[root@centos79 ~]# systemctl stop docker
Warning: Stopping docker.service, but it can still be activated by:

6.启动docker registry

命令:

docker ps -a | grep my_registry

docker start my_registry

docker ps -a | grep my_registry

[root@centos79 ~]# docker ps -a | grep my_registry
010c6b9f3935   registry:latest        "/entrypoint.sh /etc…"   26 minutes ago   Exited (2) 15 minutes ago                                                                                          my_registry
[root@centos79 ~]# 
[root@centos79 ~]# docker start my_registry
my_registry
[root@centos79 ~]# docker ps -a | grep my_registry
010c6b9f3935   registry:latest        "/entrypoint.sh /etc…"   26 minutes ago   Up 2 seconds            0.0.0.0:5000->5000/tcp, :::5000->5000/tcp                                              my_registry
[root@centos79 ~]#

7.上传镜像进行验证

命令:

docker images | grep nginx

docker tag nginx:latest 172.20.10.12:5000/nginx:1.0

docker images | grep nginx

docker push 172.20.10.12:5000/nginx:1.0

[root@centos79 ~]# docker images | grep nginx
nginx                        latest        605c77e624dd   23 months ago   141MB
[root@centos79 ~]# docker tag nginx:latest 172.20.10.12:5000/nginx:1.0
[root@centos79 ~]# docker images | grep nginx
172.20.10.12:5000/nginx      1.0           605c77e624dd   23 months ago   141MB
nginx                        latest        605c77e624dd   23 months ago   141MB
[root@centos79 ~]# docker push 172.20.10.12:5000/nginx:1.0 
The push refers to repository [172.20.10.12:5000/nginx]

[root@centos79 ~]#

 8.检查本地私有仓库

命令:

curl -XGET http://172.20.10.12:5000/v2/_catalog

curl -XGET http://172.20.10.12:5000/v2/nginx/tags/list

[root@centos79 ~]# curl -XGET http://172.20.10.12:5000/v2/_catalog
{"repositories":["nginx"]}
[root@centos79 ~]# 
[root@centos79 ~]# curl -XGET http://172.20.10.12:5000/v2/nginx/tags/list
{"name":"nginx","tags":["1.0"]}
[root@centos79 ~]#

至此,docker registry私有仓库搭建完毕!
