What's the difference between a virtual machine and Docker?

Yep, still confused but still watching

VMs run their own kernel.
Containers share the host's kernel.

Virtualisation and emulation are separate like virtual box vs pcem

Docker container can virtualise if you don’t share the kernel. You could move vms across platforms too

Love your content Tim, keep up the great work man!

This is a great description of the difference really. The dependencies really is what makes it so great I think.

Wow, I have been using dockers for years and this is like the most layman explanation I have heard. All the container and shipping analogies finally make it make sense.

Tim, your content has been foundational in my understanding of containers, docker, proxmox, nuc (but lenovo tiny) clustering, and now I have your ansible kubernetes video tee’d up for next weekend. Thank you for everything you do and the way you share all of this incredibly useful information so clearly 🫡

Tim, Another great post! Your posts always adds something to my knowledgebase. I've based my (rebuilding) of my home lab(s) on what you have done with your VMs and Docker. I was running most things in VMs (up to 140 on VMware, XCP-ng, and Proxmox. Plus desktops with VirtualBox and VMWare WS). Now I have 80+ dockers with Rancher and Portainer as appropriate. Still have a lot of VMs too, but fewer than before. :)

Not that it really matters from Docker’s perspective, but only Linux is built on Linux. MacOS and most other Apple OSs are built on a Mach microkernel with FreeBSD userland around it. FreeBSD/NetBSD/OpenBSD are descendants of the Berkeley Unix version that predates Linux, and can use Linux libraries to satisfy Linux dependencies. Windows is built on sysadmin tears.

First short video that I really like. Keep doing that.

I have about a dozen raspberry pis doing "stuff" - Just acquired an old 6i7 nuc - put in 16GB and a 1TB M2. Put down Proxmox V7 as base - next step is Ubuntu as an LXC (not a VM) then Docker on that, and they go crazy with docker containers... Also run a Synology DS918+ with Docker (and Plex) - update it to DSM7, move Plex "under" docker. Planning on doing it all with ANsible so that is is a documented and b) repeatable.

I'm so confused how this works and I've been trying to learn about it.

Containers are the answer to Linux dependency hell. Forget about snap packages and all that, just use containers.

[adriancoanda]

Docker is similar to android the apk are like docket containers

[WRod]

Great content. Thanks for all ur hard work

[aniislive]

I think the next step will be podman self hosting. Any plans for that

[ewenchan]

I think that when people talk about containers, they need to SPECIFY whether they're talking about LXC containers vs. Docker containers because those are two VERY different things.

[captainleo]

Sorry bro but from my lack of knowledge I went from hearing you talking about PC stuff to cargo ships and then back to PC stuff.

More simple, virtual machine is an abstraction of a physical machine and container is an abstraction of a host process. The purpose is the same in the end, to make machines and applications portable anywhere, like a money with the Federal Reserve (joke). Nice explain dude ;)

This us why I don't use that shit .
