# Migrating Everything to Proxmox - Part 1

</div>

It was almost inevitable that this would happen. After getting more
comfortable with Proxmox, I realized that I needed more reliability for
the applications running on my RPis. Things are running fine on my RPi,
but it was a matter of time before disaster struck. So begin my efforts
to move everything over to Proxmox.

## A Dance with Docker

While almost everything could run on or built for Docker one way or
another these days, running complicated applications on Docker will
eventually uncover some really esoteric behaviours. So I stuck to using
LXC containers for most of my applications. I used Docker for the
applications that I can deploy and leave them alone, hence Redis,
WikiJS, and WatchTower. WatchTower ensures that the containers stay
healthy and updated.

## Preparing The Base

With the easiest stuff out of the way, I started preparing the LXC
container templates. I opted for two templates: CentOS 7 and Debian 10.
I updated them, added my SSH public keys, installed the basic tools, and
it was good to go.

## Taking Apart Services on RPi

As a result of my messy installations on RPi, I had to scrounge around
for the configs and data for Gitea and Apache httpd. After that, it was
a quick tarball to be transferred over to their respective containers.
This time, I\'ve created a separate container dedicated for PostgreSQL
and MySQL. Doing so was somewhat liberating; I now know where I can
access and isolate my databases.

## The Disaster

What is a migration without a major data loss disaster? So, I lied
previously about the \'simple\' applications I run on Docker. I tried
migrating my Nextcloud instance to Docker. Sound simple right? Mount the
NFS directory on the Docker host, spin up the Nextcloud Docker image
with the directories and the already-migrated PostgreSQL user and tables
ready, and magic would take place. Turns out a new Nextcloud instance
would immediately nuke /data to set up a \'clean slate\'. My NFS
directory was clean enough, I\'ll say. To make things worse, I was
putting off scripting for my Btrfs snapshots and backups. With them, I
could\'ve easily rolled back my changes.

The silver lining was that I did not keep any important information on
the instance. As the old adage goes, backup before doing stupid things.
This cowboy move was a hard lesson for me.

## Conclusion

This concludes Part 1. Most of my time was spent untangling all the
services that I was experimenting on my RPi and deciding what gets to
live or not. So far, I\'ve learned a hard lesson and had to plan out my
migration before doing so. I only look forward for the rest to come.
