Docker and Proxmox: Working With Containers and Virtual Machines

Make Use Of ☛ I stopped fumbling with Docker containers after learning these commands
Docker lets applications and their dependencies run consistently on your computer by packaging them into containers, which are portable, isolated environments. It's the ideal solution if you want reliable, repeatable workflows without worrying about whether a tool or system works on your machine.
But effective use of Docker goes beyond installing and running containers. You'll get the best out of Docker when you know the commands that give you visibility, control, and efficiency. Mastery of the right commands transforms Docker into a tool that you can use confidently every day. So, I figured out the top commands you must master to be an accomplished Docker admin.

XDA ☛ I use a 3-2-1 backup strategy for my Proxmox snapshots – here’s how
Since I rely on my dev VMs and self-hosted containers for daily tasks, I have to keep redundant copies of my virtual guests, or risk having to rebuild everything from scratch when one of my home lab experiments backfires. Since I use Proxmox Virtual Environment for the majority of my server tasks, backing up my virtual guest stack is a piece of cake. And no, I’m not talking about the built-in vzdump facility.
Proxmox Backup Server is my preferred tool for the job, as it not only uses compression and deduplication to make my snapshots efficient, but also supports live restore and selective recovery to quickly revive essential VMs and LXCs. However, its real perk is the remote sync facility, which lets me transfer snapshots to another offsite PBS instance for a dedicated 3-2-1 backup setup.

XDA ☛ Proxmox turned my single server into a complete homelab
My self-hosting home lab setup has evolved into a pretty major part of my home, but it's interesting to me to look back and realize how it all started and how quickly it evolved. I got into this whole idea last year when I had to set up Home Assistant for the very first time, but then this year, after seeing so many of my colleagues talk about what they can do with a NAS and what self-hosting can be used for, I wanted to level up my setup.
And that's where Proxmox came into the picture. This virtualization playground has become the backbone of so many things in my home that I legitimately don't want to think about the possibility of having to go back to a time when I didn't have a home server. It turned a single, tiny computer into an incredibly useful tool for my family, and if you're even remotely curious about home labbing, I highly recommend starting here.
