WTF #Docker? (It's most likely me fucking up somewhere tho.)

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!

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!

FYI all, portainer is giving away 3 node business licenses. #kubernetes support since the last time I visited their site, so I'm interested in checking how well that interacts with #talos.
Some of my #homelab machines currently just run a few containers in #docker_compose stacks for services my #homeassistant server is using like node red and I've been using #portainer for simple things like checking status or restarting things without having to ssh into those workers. Most of those containers are going to get migrated into my #k8s cluster, so it'll be interesting to see how well it works as a quick web interface.

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.

I started building an application to schedule posts across multiple social media platforms. Details are irrelevant to this post. Suffice to say, modules are running in a #Docker container on my #SynologyNAS at home. It’s access it when I’m at home. However, I’ll soon travel to Australia for weeks, and …

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!
