Mittlerweile habe ich, ich weiß nicht mehr, wie viele #proxmox #Server und #Backup Server in Betrieb, ich weiß auch nicht mehr, mit wie vielen #Linux #Container|n #lxc und virtuellen Maschinen #kvm.
Darin laufen zudem #docker #portainer #dockge #kubernetes und noch mehr Instanzen, dass ich so langsam nicht mehr weiß, wie ich die alle administrieren kann.
Mal ganz abgesehen von den herkömmlichen öffentlichen Servern, die ein #upgrade benötigen.

Isn't part of the fun breaking the containers, then learning how to do it on bare metal, then going back to containers for convenience once you understand it?

Anytime I see "docker..." in open-source projects install docs, I run away screaming. If your app isn't trivial to build locally, who do you expect to contribute? IMHO, #Docker has never been open-source friendly. It's a barrier, not a feature.

I turned on debug mode for nginx and it seems to be making the connection to Youtube and sends data so I am really at a loss as to what is going wrong!! #docker #mac #nginx #colima #rtmp #youtube #containerizeit

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!

Are you #selfhosting an #email server?
I just published a #Docker image for the latest #Postfix version 3.10.5, based on #archlinux.
The email server is fully customizable. For usage on a Virtual Private Server (#VPS). Just use the Docker registry provided by the project. 👇

@benpocalypse I like #Docker, it keeps things neatly separated. I can roll out a service on every client system the same and controlled way. It can be very efficient. But you shouldn’t just slab sh*t together.
We build our images from scratch. God knows what’s in it otherwise.
And if something goes sideways, I hop into the container and see what’s broken like on bare metal.
But if I just follow Howto’s with no interest for the details, I’m just a script kiddie.
