It is bad practice because of point 2 and if you have multiple replicas you can probably get different versions running simultaneously (never tried it). Get Rennovate. It creates PRs to increment the version number and it tries to give you the release notes right in the PR.

Borg / k8s / Docker are not the same thing. Borg is the predecessor of k8s, a serious tool for running production software. Docker is the predecessor of Podman. They all use containers, but Borg / k8s manage complete software deployments (usually featuring processes running in containers) while Docker / Podman only run containers. Docker / Podman are better for development or small temporary deployments. Docker is a company that has moved features from their free software into paid software. Podman is run by RedHat.

There are a lot of publicly available container images out there, and most of them are poorly constructed, obsolete, unreprodicible, unverifiable, vulnerable software, uploaded by some random stranger who at one point wanted to host something.

VLANs are lower than IP so you don’t need a router to have a VLAN, but you will need a router to get packets between the networks. I don’t think a WiFi repeater works. You likely need separate WiFi client and AP devices so you can put your WiFi on a different channel. Otherwise you’re probably halving your WiFi performance when connecting to the other network over the same airwaves.

Unless you can convince the other network to route your IP addresses, this setup will give you another layer of NAT and may cause problems with online games.

The ones on Amazon are intended to run GPUs for crypto farms, but they’re all brands you’ve never heard of with dubious claims and they’ve all got at least one review where either the device was defective or something was installed incorrectly and it caused damages.

I did this but buying these on Amazon is scary. Try to find one that won’t burn your house down.
