Hi Everyone, I was trying to increase the size of a container and did something stupid after a week of putting in a lot of work into the docker LXC. I accidentally converted it to a template. All my services are now in town and that including my reverse proxy etc.

What can I do to undo my mistake?

Thank you kindly.

RightClick on the template --> Clone
Click to expand...
That what I did, unfortunately for some reason I get anything to work, the Docker LXC had Portainer and I belive this is not working when cloned and since this was not configured with a static IP, and all the services were pointing staticky to the Dynamic IP of the docker container, its a mess. I was hoping to revert the template back, so everything would get restored.

I had Traefik running on the docker and so all my SSL certs are gone.

I created a new Traefic instance temporarily, but I think since the certs were already issued to the other container, there is some issue with that, its not working as well.

The above are the configuration changes that happen when you convert a container to template. You can manually "undo" them following a procedure similar to https://forum.proxmox.com/threads/undo-convert-to-template.35386/

This is not an official way, obviously

I ended up re-creating the entire project from ground up again. The issue was that I could not get all the dots to connect. Since docker and portainer were on that LXC, After recreating everything, I also ended up deciding to move the services out of the LXC to a VM and also backup everything.
