Project mention: Your laptop can run a full devops stack here’s how I set mine up | dev.to | 2025-06-19
Push and pull images without Docker Hub rate limits. Harbor has a slick UI and RBAC. Docker Registry UI is minimal and works well.

For updates, I’m using a container called Watchtower that updates my Docker images automatically, together with unattended-upgrades to update system security packages.

Over time, registries accumulate a lot of garbage in the form of blobs referenced by old images that are not needed anymore. Many registry implementations, such as CNCF Distribution, offer garbage-collection mechanisms to delete unreferenced blobs and free up storage space. However, for that to happen, old images (tags) referencing them have to be deleted first.

Additionally at some point people behind this product decided to change the licensing model, and allow the use of community editions for up to 5 nodes. It wasn't my case, but that pushed me to use something more independent. So I started using dockge, then added another service for docker logs, version monitor, and keeps adding applications that are fun to use, for example homebox or bookstack. It was fun until I released the cost of energy and maintenance effort need to keep it running, at my home. Every internet issue, or power issue takes my setup down. Maybe it was not happening very often, but when I wasn’t home, and the hardware was down, there was no chance to fix it remotely. And I started relaying on that service. That is why I simply decided to migrate to hetzner, and podman at the same time, and use remote NFS. However, let's start from the beginning.
