+# Docker Hub local mirror
+Since docker.com has limited access to container images there it is necessary to mirror container images locally
+and pull them with an account for more than personal use of a few images.
+That is especially true for maintaining or restoring a K8s cluster as this will exhaust the free contingent fast.
+# Using a storage node
+This has the benefit of using the 10GB link, for example 10.3.6.58:
+Config file `/etc/docker/registry/config.yaml`
+```yaml
+version: 0.1
+http:
+  secret: <some string>
+  addr: 0.0.0.0:5000
+  debug:
+    addr: :5001
+    prometheus:
+      enabled: false
+      path: /metrics
+  headers:

+  remoteurl: https://registry-1.docker.io
+  username: <docker hub account>

+Launch:
+```bash
+sudo podman run -d -p 10.6.16.58:5000:5000 \
+ -v /var/lib/registry:/var/lib/registry \
+ -v /etc/docker/registry/config.yml:/etc/docker/registry/config.yml \
+ --name docker-registry-proxy \
+ --log-driver journald registry:2.8
+```
+Restart with systemd (`/etc/systemd/system/docker-registry-proxy.service`):
+```ini
+[Unit]
+Description=DockerHub Registry Proxy Server
+[Service]
+Restart=on-failure
+ExecStart=/usr/bin/podman start -a docker-registry-proxy
+ExecStop=/usr/bin/podman stop -t 10 docker-registry-proxy
