3. Create a docker group

Used to pull images to local use, you can download images from the external network and push images from local to private libraries

Click "create Repository" and select docker (group) to create

Used to download from the warehouse. You can download images from external warehouses and images uploaded by yourself.

Configuration parameters

Click "create repository" to create

4. Configure Docker Realm

Configure Docker Bearer Token Realm to the right and click save.

2. Docker configuration

Here we use http, not https, so we need to modify the docker configuration file

Use the command vi /etc/docker/daemon.json to modify the docker configuration file

Add the following parameters: the IP address is the IP address of the private library server, and the port is the port filled in when creating the docker group and docker hosted

{
“insecure-registries”: [“192.168.99.1:8088”, “192.168.99.1:8089”]
}

Then save it. After saving successfully, restart docker

Use docker info to check whether the configuration is successful. If the following information is displayed, the configuration is successful.

3. Upload and download images

1. Download the image

Use docker pull 192.168.99.1:8089/ubuntu to pull the image

Because anonymous pull was checked in the previous configuration, you don't need to log in to pull. If you need to control permissions and prevent anonymous pull, uncheck the following configuration

2. Upload the image

You can query the image just uploaded on nexus

Use docker pull 192.168.99.1:8088/centlocal:1.0 to pull the uploaded image
