私有仓库图例

私有仓库配置

主机名	ip地址	最低配置
registry	192.168.1.30	2CPU,4G内存

[root@registry ~]# yum install -y docker-distribution
[root@registry ~]# systemctl enable --now docker-distribution
[root@registry ~]# curl http://127.0.0.1:5000/v2/_catalog
{"repositories":[]}

客户端配置

所有node节点都需要配置，这里 docker-0001，docker-0002都要配置

[root@docker-0001 ~]# vim /etc/hosts
192.168.1.30	registry
[root@docker-0001 ~]# vim /etc/docker/daemon.json
{"exec-opts": ["native.cgroupdriver=systemd"],"registry-mirrors": ["http://registry:5000","https://hub-mirror.c.163.com"],"insecure-registries":["192.168.1.30:5000","registry:5000"]
}
[root@docker-0001 ~]# docker rm -f $(docker ps -aq)
[root@docker-0001 ~]# systemctl restart docker

上传镜像

[root@docker-0001 ~]# docker tag myos:latest registry:5000/library/myos:latest
[root@docker-0001 ~]# docker push registry:5000/library/myos:latest
The push refers to repository [registry:5000/library/myos]

验证测试

查看镜像名称： curl http://仓库IP:5000/v2/_catalog
查看镜像标签： curl http://仓库IP:5000/v2/镜像名称/tags/list

[root@docker-0002 ~]# vim /etc/hosts
192.168.1.30	registry
[root@docker-0002 ~]# vim /etc/docker/daemon.json
{"exec-opts": ["native.cgroupdriver=systemd"],"registry-mirrors": ["http://registry:5000","https://hub-mirror.c.163.com"],"insecure-registries":["192.168.1.30:5000","registry:5000"]
}
[root@docker-0002 ~]# docker rm -f $(docker ps -aq)
[root@docker-0002 ~]# docker rmi -f $(docker images -aq)
[root@docker-0002 ~]# systemctl restart docker
# 查看镜像名称
[root@docker-0002 ~]# curl http://registry:5000/v2/_catalog
{"repositories":["library/myos","myimg/centos"]}
# 查看镜像标签
[root@docker-0002 ~]# curl http://registry:5000/v2/library/myos/tags/list
{"name":"library/myos","tags":["latest","httpd","phpfpm","nginx","v2009"]}
# 仓库中的 library 是默认路径，允许容器不需要指明地址
[root@docker-0002 ~]# docker run -it myos:v2009
