Emby and Jellyfin with Podman

Posted by KarlP on 24 May, 2024 None comments

I had some “unplanned outages” with my home infrastructure, and had to quickly get something up to watch some TV. I was planning on running plex again, when the “main” infrastructure is up again, but took a moment to try out Emby and Jellyfin, to see what they’re like. I’m just running them as quick demos from my main PC, so I had zero intention of setting up some permanent custom linux. And I’ve gotten pretty happy with podman these days, instead of root docker, so….

Emby

$ podman run -d -p 8096:8096 -v $(realpath some-place-to-keep-config):/config:z  -v /mnt/<some local path to tv>:/mnt/share-tv:z emby/embyserver:latest

Pretty normal really. Add as many volume maps as you need for different media types, remembering that everything for the last X years insists that tv and movies are kept in entirely separate top level directories…. for… reasons…. The :z is “normal” to get the mapping permissions right

I’ve not yet tested whether it’s finding things well with local web browsing, might need a –network=host but… nothing special.

Jellyfin

Same same…. Just had to map the port differently, as I was running them both side by side to give them a try…

$ podman run -d -p 8097:8096 -v $(realpath media-jellyfin/config):/config:z -v $(realpath media-jellyfin/cache):/cache:z  -v /mnt/blah/somewhere/tv:/mnt/share-tv:z jellyfin/jellyfin:latest

Now to just see how they both go?

Home Assistant Matter Server with Podman

Posted by KarlP on 28 June, 2023 None comments

Yet more updates, turns out as of a few days ago, they now actually provide a container of the matter server _without_ all the home assistant OS cruft. so it’s even easier:

$ podman run -v /etc/localtime:/etc/localtime:ro -v /run/dbus:/run/dbus:ro  -d --network=host ghcr.io/home-assistant-libs/python-matter-server:stable

(Original below)

so, home assistant only formally supports matter via an home assistant “Addons” which are only supported by the Home Assistant “OS”. That’s… not a cool way of runnings for me, and all it really does is run a docker server wrapping an external service they made, python-matter-server

The Docker service they made is here: https://github.com/home-assistant/addons/tree/master/matter_server This… doesn’t run nicely with podman, but it can mostly be worked around pretty easily.

So, assuming you have home assistant already running on localhost, under podman:

$ podman run -v /etc/localtime:/etc/localtime:ro -v /run/dbus:/run/dbus:ro  -d --network=host -e SUPERVISOR_API=http://localhost docker.io/homeassistant/aarch64-addon-matter-server:latest

The -e SUPERVISOR_API call doesn’t actually do anything, because you don’t actually have the home assistant supervisor, but it might be helpful in some cases, and shows you how to do it anyway.

Originally there were more instructions, below, but they actually went and fixed my bug report eventually, so you no longer need anything other then “usual” podman invocations on their default image.

Unfortunately you will need to edit a few layers, as they seem pretty against letting this be run easily without their entire OS

# First make sure we're up to date
$ podman pull docker.io/homeassistant/aarch64-addon-matter-server
# now, run that, and get a shell in it, we need to edit...
$ podman run -d docker.io/homeassistant/aarch64-addon-matter-server
390841611cf49675741ec72ea91341aef628fd6865bba51eeee9d0f1533473b8
$ podman exec -it -l /bin/bash
root@390841611cf4:~#

Ok, now, what are we fixing? Well, the log line from that bug report linked first… Despite closing my issue, they actually fixed this later…

That… actually means you don’t need to do any image fuckery at all… Lets just do some magic podman to replicate the docker file sufficiently…

Podman and OpenCart

Posted by KarlP on 26 April, 2023 None comments

I have been doing some experiments with shopping cart systems, and was trying to run them on podman for some “quick” testing. (I’m not much of a container expert, but I don’t have a php setup on my workstation right now, so this seemed like a good time to become one)

Now, OpenCart installation instructions are super manual but that shouldn’t be too hard right?

Well, after a bit of faffing around, looking for an nginx+php-fpm container ready to go, I just fell back and tried:

$ podman run -p 8081:80 -d -v ./opencart-4.0.2.1/upload:/var/www/html php:8-apache

This runs ok, but you’ll instantly get problems trying to access it:

Warning: mkdir(): Permission denied in /var/www/html/system/storage/vendor/twig/twig/src/Cache/FilesystemCache.php on line 50
Warning: file_put_contents(/var/www/html/system/storage/logs/error.log): Failed to open stream: Permission denied in /var/www/html/system/library/log.php on line 34
Warning: file_put_contents(/var/www/html/system/storage/logs/error.log): Failed to open stream: Permission denied in /var/www/html/system/library/log.php on line 34RuntimeException: Unable to create the cache directory (/var/www/html/system/storage/cache/template/c3). in /var/www/html/system/storage/vendor/twig/twig/src/Cache/FilesystemCache.php on line 53

Ok… you are clever and wise, and have been around computers. You understand, in your bones, that podman’s rootless containers means that “apache” is really running as your normal user id, but thinks it has another id inside the container. You do a lot of reading about “podman unshare” but, you really don’t give a shit what fucking UID is being used inside the php apache container?! You finally find what sounds like the right solution, which sounds exactly right, but… not… quite?

$ podman run -p 8082:80 -d --userns=keep-id -v ./opencart-4.0.2.1/upload:/var/www/html php:8-apache
0e726377f1ecdf7120cdd74f9c9b89b424eba6602c01c167440da91e7069685a

$ podman logs -l
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 10.0.2.100. Set the 'ServerName' directive globally to suppress this message
(13)Permission denied: AH00072: make_sock: could not bind to address [::]:80
(13)Permission denied: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs

Ok, this is because apache runs as root to bind port 80 inside the container, even though you’re always going to map it from the outside anyway, that sucks. Ok, one more bit of magic right? We can just tell the container that it’s allowed to bind to low ports!

podman run -p 8083:80 -d --userns=keep-id --sysctl net.ipv4.ip_unprivileged_port_start=0 -v ./opencart-4.0.2.1/upload:/var/www/html php:8-apache

And you finally get the OpenCart installation page at http://localhost:8083 None of this addresses the rest of the installation, like “removing the install folder once you’re done” and “configure mysql…”
