CentOS 6.5.How to make Docker Registry image
This article to share with you is about CentOS 6.5 how to make Docker Registry image, Xiaobian think it is very practical, so share it with you to learn, I hope you can gain something after reading this article, not much to say, follow Xiaobian to see it.
docker pull in China always fails to pull files down properly, now you can make your own mirror server
The steps to create a Docker image are as follows:
This article assumes that the local IP is 192.168.56.101 and the domain name of the Registry service is registry.feedao.com
The first step is to create a centos-registry image by executing the following command:
docker build -t centos-registry https://git.oschina.net/feedao/Docker_shell/raw/start/Dockerfile-registry
Step 2: Create a registry container, listening on ports 22 and 5000.
docker run -d -p 127.0.0.1:33307:22 -p 127.0.0.1:5000:5000 centos-registry
Testing:
[root@docker-base docker-temp]# curl 127.0.0.1:5000
"docker-registry server (dev)" appears, indicating that the registry process is automatically terminated.
Step 3: Configure nginx:
yum -y install nginxservice nginx startecho -e "server {\n listen 80;\n server_name registry.feedao.com;\n location / {\n proxy_set_header Host \$host;\n proxy_pass http://127.0.0.1:5000/;\n }\n}" >>/etc/nginx/conf.d/virtual.conf service nginx reloadecho "127.0.0.1 registry.feedao.com" >> /etc/hosts
Testing:
[root@docker-base docker-temp]# curl registry.feedao.com
"docker-registry server (dev)" appears for success
Step 4: Use your own registry server.
Tag the local image:
docker tag centos-newssh registry.feedao.com/centos-newssh
Push the image of the tag to the registry server:
docker push registry.feedao.com/centos-newssh
Step 5, change the server configuration hosts file, for example, my registry server IP is 192.168.56.101,
Configure hosts on 192.168.56.102 on another server
echo "192.168.56.101 registry.feedao.com" >> /etc/hosts
Then execute:
docker pull registry.feedao.com/centos-newssh
Create container: docker run -d -p 127.0.0.1:33306:22 -m 256M registry.feedao.com/centos-newssh
Login: ssh root@127.0.0.1 -p 33306
Password: 123456
The above is how CentOS 6.5 makes Docker Registry images, Xiaobian believes that some knowledge points may be seen or used in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
