[Docker] Build a private warehouse

Docker builds a private warehouse

1 Build a private warehouse

The ip address used below refers to the address of the local machine, which can be viewed by the following command:

$ ip addr

Now start to build a private warehouse: since the registry is also a mirror, we pull it and start a container. Port mapping via 5000:5000.

# 1.拉取私有仓库镜像
sudo docker pull registry
# 2.启动私有仓库容器，宿主机port:容器port
sudo docker run -id --name=registry -p 5000:5000 registry

Then open the browser, enter the following URL, and replace the ip with the local address:

# 3.打开浏览器，输入：http://ip:5000/v2/_catalog
# 看到{"repositories":[]}表示私有仓库搭建成功

Next, we need to trust the private warehouse, and replace the ip with the local address:

# 4.修改daemon.json
sudo vim /etc/docker/daemon.json
# 在该文件中添加一个key即可，用于让docker信任私有仓库地址
# {"insecure-registries": ["ip:5000"]}

If you want to use multiple private repositories, separate them with commas, for example: ["ip1:port1", "ip2:port2"]

Finally restart the docker service:

# 5.重启docker服务
systemctl restart docker
sudo docker start registry

2 Upload the image to the private warehouse

# 1.标记镜像为私有仓库的镜像
sudo docker tag <IMAGE:TAG> ip:5000/<IMAGE:TAG>
# 2.上传标记的镜像
sudo docker push ip:5000/<IMAGE:TAG>

3 Pull the image from the private warehouse

# 拉取镜像
sudo docker pull ip:5000/<IMAGE:TAG>
