+1 for Veeam. I am a backup administrator and this is our tool of choice. I use it for my home machines as well and it works great.

Just remember, you don’t have a backup unless you have tested it.

Terny has the correct answer here OP. While I have never used Docker in an enterprise environment (manufacturing applications aren’t known for supporting any technology from the last decade at least), I have used Docker extensively in my home lab. You don’t want to modify the container itself, but the image it was created from. The data doesn’t reside in the container itself anyway, but typically a volume attached to the container (assuming it stores anything in the first place). Your best bet will be to figure out what image the container was created from, and modify the image. From there, you can update the existing containers to use the new image, or move them elsewhere if you like.

You mentioned these VM’s are in the cloud. Depending on the hyperscaler, it is likely that you could migrate these to a native container service to save on cost since you wouldn’t have to pay for the overhead of a VM.

Hey, we all start somewhere! I ordered mine from keyhive and made the mistake of ordering the DIY version. I usually like to do things myself, but had a hell of a time soldering the SMD diodes on. I would recommend the partially assembled version. Keyhive also lists the other parts you will need. If you order the partially assembled version, you will only need a microcontroller, switches, and caps for a complete keyboard! Keyhive also lists the microcontrollers you can use. Personally, I love the nice!nano. It ads BLE and the battery lasts for quite a while. You will need to solder the microcontroller, but it’s easy to do assuming you have an iron. Let me know if you have more questions!

The Corne is a very popular split keyboard that is very cheap. It requires some level of DIY, but the main board can be had for $33. It can also be made Bluetooth with the nice!nano. You will still need switches and caps, but depending on what you’re after, those can be cheap as well.
