Any API or Web UI project to manage a Docker private registry?

Question

I can't find how to manage images in a private registry. I can push or pull an image because i know the id but how to get the list of pushed images ?

Take for example a person who wants to see the available images under the private registry of his organization. How can she do ?

Unless I'm mistaken, I can't find API or Web UI to discover the registry content like the index.docker.io do with the public registry.

Are there any open source projects to manage this ?

thanks.

Answer 1

Are there any open source projects to manage this ?

There is a containerized web application that provides administration of one-to-many private registries. Its name is Docker Registry UI and it is FOSS.

The source is on Github and you can run it in a container like so:

docker run -p 8080:8080 -v my_data_dir:/var/lib/h2/ atcol/docker-registry-ui

Disclaimer: I wrote the web-app as I could not find one myself. I believe this answers your question (as quoted).

Thanks Thomas !

To allow the use of the search API, you must start the container by specifying the value of the environment variable SEARCH_BACKEND like this :

docker run -d -e SEARCH_BACKEND=sqlalchemy -p 5000:5000 --name registry samalba/docker-registry 

Then i have a result for this query :

GET http://registry_host:5000/v1/search?q=base  Result : {     "num_results": 1,     "query": "base",     "results": [{"description": "", "name": "test/base-img"}] } 

To list all images, you can do this :

GET http://registry_host:5000/v1/search  Result : {     "num_results": 2,     "query": "",     "results": [        {"description": "", "name": "test/base-img"},        {"description": "", "name": "test/base-test"}] } 

And to know the available versions of an image :

GET http://localhost:5000/v1/repositories/**test/base-img**/tags  Result : {   "0.1": "04e073e1efd31f50011dcde9b9f4d3148ecc4da94c0b7ba9abfadef5a8522d13",   "0.2": "04e073e1efd31f50011dcde9b9f4d3148ecc4da94c0b7ba9abfadef5a8522d13",   "0.3": "04e073e1efd31f50011dcde9b9f4d3148ecc4da94c0b7ba9abfadef5a8522d13" }
