How to query or obtain images in a private registry

Docker queries or obtains images in a private registry, using

docker search 192.168.1.8:5000

The command did not work after testing.

solve:

1. Get the image of the warehouse class:

[root@shanghai docker]# curl -XGET http://192.168.1.8:5000/v2/_catalog

{"repositories":["nginx"]}

2. Get the tag list of a certain image:

[root@shanghai docker]# curl -XGET http://192.168.1.8:5000/v2/image_name/tags/list

{"errors":[{"code":"NAME_UNKNOWN","message":"repositoryname not known toregistry","detail":{"name":"image_name"}}]}

[root@shanghai docker]# curl -XGET http://192.168.1.8:5000/v2/nginx/tags/list

{"name":"nginx","tags":["latest"]}

[root@shanghai docker]#

PS: View all tags of images in the Docker image repository

#!/bin/sh

repo_url=https://registry.hub.docker.com/v1/repositories
image_name=$1

curl -s ${repo_url}/${image_name}/tags | json_reformat | grep name | awk '{print $2}' | sed -e 's/"//g'

In fact, the implementation method is to query through the restful API of the image repository, then simply process the returned json result and print it out.

The above script is implemented to query only from hub.docker.com. If you use other warehouses, you can modify the warehouse URL as needed.
