Understanding #Docker Internals: Building a Container Runtime in Python
https://muhammadraza.me/2024/building-container-runtime-python/
I was trying to run the Portracker container so I could get a quick overview of the ports currently in use on my server. I couldn't do it because the default port for this container is currently being used by another one. What a paradox!
#docker
🖥️ Communicates with Windows using WinBoat Guest Server to retrieve necessary data and manage applications running in the containerized environment
📋 System requirements: At least 4GB RAM, 2 CPU threads minimum, 32GB free storage space in /var directory, KVM virtualization enabled in BIOS/UEFI
🐳 #Docker installation required for containerization, Docker Compose v2 for compatibility…
Har fått igång #homeassistant och länkat den med #musicassistant . Men jag kan inte söka musik från HA appen utan behöver styra musiken från MA via en webbläsare. Kör i #docker och …
WTF #Docker? (It's most likely me fucking up somewhere tho.)
I'm getting closer with my nginx-rtmp-Docker-container-on-MacOS project!
I started from scratch on the mac a couple days ago, reinstalled docker with homebrew and then realized that part of my problem was that macOS (and windows) has to run docker in a virtual machine container of its own and *that* can mess with networking.
So I have now figured that out. Colima, the vm that seems most popular on macOS, needs a mac specific option (--network-attached) when starting so that it gets the mac network going. Major Aha! moment.
I also learned more completely how to build my own Docker images.
I've gotten to the point where nginx is definitely running, I know the port is open (via nmap on another device), I know nginx is accepting the stream, but nginx still refuses to publish that stream to Youtube (or at least youtube is not seeing it).
I also can ping apple.com and youtube.com from within the container, so access to the outside world is working.
I
So that's where I'm at.
I just figured out how to get into a container and examine the nginx log files now.
At this point I am going to rebuild the container with nginx configured for full debug level logging. Hopefully that provides some more clues on where it is getting stuck.
I give it a 50/50 chance that it is either an nginx configuration/installation problem or another colima virtual machine/networking issue.
I've learned a lot at least and feel better about my overall Docker knowledge!
And I'm documenting on my blog as I go so I'll have a howto produced from this when it finally works!

Für mein #Roadwarrior Notebook habe ich mich entschieden, in #Docker eine #Pihole Installation zu machen. Läuft.
Klasse! :blobcatsunglasses:
AHA! #docker #nginx #mac Success!
After much logging and inspecting and reconfiguring you know what worked? (It's what always works!). Turning it off and on…
It's just a matter of turning the *right* thing off and on.
In this case, it was a matter of rebooting the webcam itself, which I really should have known because it has been unreliable at accepting new settings without a full reboot in the past. Weird that it was making the connection to NGINX but not actually sending data on that connection. The reboot of the webcam appears to have forced the data to be sent to the new proper docker address and on to Youtube.
Unfortunately I tried changing the stream key for Youtube before trying the webcam reboot which creates a new youtube URL, so I'll have to update my YouTube embed codes but oh well, it is worth having success with docker!
I feel much more comfortable working with docker now and understand the build/run workflow more now so I can start customizing my Dockerfile and be confident that I’m not going to miss anything.
Now I should be able to redirect all of my streams off of #footiMac and onto the slightly newer #imac2014 OR... most importantly, anywhere I have this docker container!
Woot!
Thank you everyone who gave tips and pointers along the way.

Finished my little tutorial as I got docker running on my 2014 macOS Ventura era iMac and then added some nginx-rtmp containers.

bam! Docker Mission Accomplished!

All webcam streams have been redirected from a single nginx process on #footiMac (which is also, of course, running this very mastodon #selfhost!) to their own docker containers on another iMac using Docker CLI/Colima.
I can already 'feel' the difference in response time for footiMac and posting/updating on mastodon! Yay!

Comme il fait moche dehors 🌧️
j’ai décidé de faire encore pire :
je lance Windows… dans Linux 😅
Test de WinBoat ⛵️ : une appli qui promet de faire tourner les logiciels Windows sans #VirtualBox, #VMware ni #wine
Mais avec #docker 📦
Si ça marche, je renomme mon PC ”Emultima"
