Attempt to start a basic local registry using the image:

1. Pull registry image

   1. pnispero@PC100942:~/BuildSystem/artifact_storage$ docker pull registry:2
      2: Pulling from library/registry
      619be1103602: Pulling fs layer
      862815ae87dc: Pulling fs layer
      74e12953df95: Pulling fs layer
      6f0ce73649a0: Waiting
      ef4f267ce8ed: Waiting

2. Run the registry

   1. pnispero@PC100942:~/BuildSystem/artifact_storage$ docker run -d \
        -p 5000:5000 \
        --restart=always \
        --name registry \
        -v /mnt/registry:/var/lib/registry \
        registry:2
      6fc1b5baf2faded8842cec71a382a1b9b3a7b6ce6a664c376c2f7a824e3ea17a

3. Push an image to registry

   1. docker tag pnispero/rocky9-env:latest localhost:5000/rocky9-env

   2. docker push localhost:5000/rocky9-env

4. Check /mnt/registry/ and also shell into the registry container and check /var/lib/registry

   1. pnispero@PC100942:~/BuildSystem/artifact_storage$ ls /mnt/registry/docker/registry/v2/
      blobs/        repositories/
      pnispero@PC100942:~/BuildSystem/artifact_storage$ ls /mnt/registry/docker/registry/v2/repositories/
      rocky9-env

   2. pnispero@PC100942:~$ docker exec -it registry /bin/sh
      / # ls /var/lib/
      apk/       misc/      registry/  udhcpd/
      / # ls /var/lib/registry/docker/registry/v2/
      blobs/         repositories/  test.txt
      / # ls /var/lib/registry/docker/registry/v2/repositories/rocky9-env/

5. We'll do something similar when deploying the container to kubernetes, and we can mount sdf as the volume. I also added a 'test.txt' to see if you can store other things besides the images.

The more complicated part will be to run an externally-accessible registry, not localhost, setting up tls/authentication, load balancing,
