Docker仓库搭建(Registry + Portus)

1.更新系统:

    yum update -y

2. 安装docker-compos

   yum -y install epel-release    #pip安装包在epel源中
   yum -y install python-pip
   pip install -U docker-compose

3.安装git客户端

  yum install -y git

4.复制Portus安装程序

  git clone https://github.com/SUSE/Portus.git

5.配置Docker安装源

  vi /etc/yum.repos.d/docker.repo
    [dockerrepo]
     name=Docker Repository
    baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
    enabled=1
    gpgcheck=1
    gpgkey=
    https://yum.dockerproject.org/gpg

6.安装docker引擎并启动

   yum cleal all && yum makecache
  yum install -y docker-engine
  systemctl start docker.service
  systemctl enable docker.service

./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



8、打开防火墙端口

firewall-cmd --zone=public  --add-port=3000/tcp --permanent
firewall-cmd --zone=public  --add-port=5000/tcp --permanent
systemctl restart firewall.service



9. 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

# ps -ef|grep insecure-registry
root     29486     1  0 01:32 ?        00:00:00 /usr/bin/dockerd --insecure-registry 192.168.0.109:5000

11. 重启Portus容器:

docker start portus_db_1 portus_web_1 portus_crono_1 portus_registry_1

12.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

13.下载镜像测试

    docker pull 192.168.0.109:5000/admin/busybox
