docker私有仓库图例

私有仓库配置

主机名	ip地址	最低配置
registry	192.168.1.100	1CPU,1G内存

[root@registry ~]# yum install -y docker-distribution
[root@registry ~]# systemctl enable --now docker-distribution
[root@registry ~]# curl http://192.168.1.100:5000/v2/_catalog
{"repositories":[]}

仓库配置文件及数据存储路径

• /etc/docker-distribution/registry/config.yml
• /var/lib/registry/
• 默认端口号 5000

查看私有镜像仓库中镜像名称或标签

• curl http://仓库IP:5000/v2/_catalog
• curl http://仓库IP:5000/v2/镜像名称/tags/list

注意：私有仓库中的镜像与docker images 看到的不是一个东西

docker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
cgroup驱动 docker默认 是cgroupfs
registry-mirrors 默认下载仓库，使用国内源能快一点
insecure-registries 私有仓库地址（重点）

#新建daemon.json文件：
[root@docker-0001 ~]# vim /etc/docker/daemon.json
{
    "exec-opts": ["native.cgroupdriver=systemd"],
    "registry-mirrors": ["https://hub-mirror.c.163.com"],
    "insecure-registries":["192.168.1.100:5000", "registry:5000"]
}
[root@docker-0001 ~]# docker rm -f $(docker ps -aq)
[root@docker-0001 ~]# systemctl restart docker

上传镜像

# 上传 myos:latest, myos:httpd, myos:nginx, myos:php-fpm
[root@docker-0001 ~]# docker tag myos:latest 192.168.1.100:5000/myos:latest
[root@docker-0001 ~]# docker push 192.168.1.100:5000/myos:latest

验证测试

[root@docker-0002 ~]# curl http://192.168.1.100:5000/v2/_catalog
{"repositories":["myos"]}
[root@docker-0002 ~]# curl http://192.168.1.100:5000/v2/myos/tags/list
{"name":"myos","tags":["latest"]}
# 使用远程镜像启动容器
[root@docker-0002 ~]# docker run  -itd -p 80:80 192.168.1.100:5000/myos:nginx
