Docker仓库搭建（Registry + Portus）
1、安装CentOS 7.2（步骤略）2、更新系统
1
yum update -y
3、安装docker-compose
1
2
3
yum -y install epel-release #pip安装包在epel源中
yum -y install python-pip
pip install -U docker-compose
4、安装git客户端
1
yum install -y git
5、复制Portus安装程序
1
2
git clone
https://github.com/SUSE/Portus.git
6、配置Docker安装源

vi /etc/yum.repos.d/docker.repo
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
enabled=1
gpgcheck=1
gpgkey=
https://yum.dockerproject.org/gpg
7、安装docker引擎并启动

./compose-setup.sh -e 192.168.0.109
#安装过程中会下载registry、mariadb、rails、ports_web等几个docker镜像
#如果网络不好可以先下载对应的几个docker镜像文件
#然后上传到portus服务器上并用docker load命令加载。
#镜像的具体版本号以实际为准。

###################
Make sure port 3000 and 5000 are open on host 192.168.0.109
Open http://192.168.0.109:3000 with your browser and perform the following steps:
1. Create an admin account
2. You will be redirected to a page where you have to register the registry. In this form:
- Choose a custom name for the registry.
- Enter 192.168.0.109:5000 as the hostname.
- Do *not* check the "Use SSL" checkbox, since this setup is not using SSL.
Perform the following actions on the docker hosts that need to interact with your registry:
- Ensure the docker daemon is started with the '--insecure-registry 192.168.0.109:5000'
- Perform the docker login.
To authenticate against your registry using the docker cli do:
$ docker login -u <portus username> -p <password> -e <email> 192.168.0.109:5000
To push an image to the private registry:
$ docker pull busybox
$ docker tag busybox 192.168.0.109:5000/<username>busybox
$ docker push 192.168.0.109:5000/<username>busybox
9、打开防火墙端口
1
2
3
firewall-cmd --zone=public--add-port=3000/tcp --permanent
firewall-cmd --zone=public--add-port=5000/tcp --permanent
systemctl restart firewall.service
10、Portus初始化
1
在浏览器中打开创建默认管理员用户
连接到本docker仓库（也可以是其他仓库，必须是registry 2.0以上版本）
10、上传镜像测试
修改文件/lib/systemd/system/docker.service中的ExecStart增加--insecure-registry 192.168.0.109:5000并重启docker服务
1
2
systemctl daemon-reload
systemctl restart docker.service
检查docker服务
1
2
# ps -ef|grep insecure-registry
root 29486 10 01:32 ? 00:00:00 /usr/bin/dockerd --insecure-registry 192.168.0.109:5000
下载busybox镜像并上传到私有的仓库中（安装结束时有操作提示）
docker pull busybox
docker tag busybox 192.168.0.109:5000/admin/busybox
docker login -u admin -p admin123 192.168.0.109:5000
docker push 192.168.0.109:5000/admin/busybox
检查Portus界面的镜像信息
11、服务器重启后处理
应该先启动
比较符合实际情况
