Build a Docker registry private image to resolve the Docker private warehouse push error

applies To: Docker 1.8 Environment: Centos7

Each version of the Docker modification configuration content is different, please be optimistic about the installation of the Docker version.

1) Download Docker Registry private image

# Docker Pull Docker.io/registry

2) Modify the configuration file

# Gedit/etc/sysconfig/docker

Options= '--selinux-enabled--insecure-registry 192.168.137.17:5000 '

Note: The red IP is the modified part

3) Start the registry from the container

# Docker run-d-P 5000:5000--name registry-v/home/dockeruser/data:/tmp/registry docker.io/registry

Note:-D indicates that the container is running in the background

-P maps the host's 5000 port to the container's 5000 port

--name name the container named registry

-V means to change the storage location of the mirror "/tmp/registry" to "/home/dockeruser/data" of the host

Note: This step must be after step 2), otherwise modifying the configuration file will not take effect

4) before uploading to a private registry, you need to specify a new registry destination address, which needs to be preceded by the image name

Prefix of host name and port.

#docker Images Node/helloworld

Get 22d56cbd9e6

#docker tag 22d56cbd9e6 192.168.137.17:5000/node/helloworld

Note: 192.168.137.17:5000 is the IP address and port of the host

5) Upload the tagged image to the private library

# Docker Push 192.168.137.17:5000/node/helloworld
