DontNoodles

I am still figuring it out since it is my hobby and I'm unable to devote much time to it. But I think it will be something like Ubuntu live disks which enabled you to try Ubuntu by running it from a DVD. You could run anything like web server, save files, settings etc. Only they would not persist after a reboot since every thing was saved in RAM. Only here it'll be a write locked SD card instead of a DVD.

I'm also sure there must be a name for it and step by step tutorial somewhere. If only Google was not so bad these days...

It might not be applicable to you but in many cases single board computers are used where there is minimal changes in files in day to day basis. For example when used for displaying stuff. For such cases, it is useful to know that after installing all the required stuff, the SD card can be turned into read only mode. This prolongs its life exponentially. Temporary files can still be generated in the RAM and if needed, you can push them to an external storage/FTP through a cron job or something. I have built a digital display with weather/photos/news where beyond the initial install, everything is pulled from the internet. I'm working towards implementing what I've suggested above.

I've heard good things about H2O AI if you want to self host and tweak the model by uploading documents of your own (so that you get answers based on your dataset). I'm not sure how difficult it is. Maybe someone more knowledgeable will chime in.

I think I'm not aware of the exporting/publishing part and that's the cause of my woes. I get everything running on the machine with unrestricted access, move to the machine with restricted access go "docker compose up" and get stuck. I'll read up on exporting/publishing, thank you.

Thank you for these links, they look just right. Most tutorials I come across these days are videos. Maybe they are easier to make. These tutorials that allow you to tinker at your own pace seem better to me. Will you mind if I reach out to you over DM if I get stuck at something while learning and am not able to find the right answer easily?

I'm not much into new year resolutions, but I think I'll make a conscious effort to learn Docker in the coming months. Any suggestions for good guides for someone coming from VM end will be appreciated.

I hate it very much. I am sure it is due to my limited understanding of it, but I've been stuck on some things that were very easy for me using VM.

We have two networks, one of which has very limited internet connectivity, behind proxy. When using VMs, I used to configure everything: code, files, settings on a machine with no restrictions; shut it down; move the VM files to the restricted network; boot and be happily on my way.

I'm unable to make this work with docker. Getting my Ubuntu server fetch its updates behind proxy is easy enough; setting it for python Pip is another level; realising the specific python libraries need special keys to work around proxies is yet another; figuring out how to get it done for Docker and python under it is when I gave up. Why can it not be as simple as the VM!

Maybe I'm not looking using the right terms or maybe I should go and learn docker "properly", but there is no doubt that using Docker is much more difficult for my use case than using VMs.

Just want to add for anyone who might attempt this, my IRC client of choice is Pidgin. Open source and works on windows as well as Linux (not sure about iOS). Most tutorials suggest the good old mIRC, but using it after the trial period increasingly becomes a pain with its wait screen with timer.
