I've decided that rather than just taking notes in my own wiki to be forgotten I'm going to start a rudimentary blog.
Here's post 1 of 2 on running #traefik in #podman with Quadlets. The end goal in part 2 will be getting #headscale running for a fully controlled #tailscale VPN. Stay tuned!

Incredible how Alexander Larsson was ahead of times with that reply about sharing libraries, it's basically the approach by Docker images... but OSTree, used by Flatpak, predates Docker and it is even more efficient with its by-file deduplication. And the recent #ComposeFS by the same author will allow #Podman containers to have the same deduplication not only on disk but even on RAM (to my understanding)
Finally moved my home server off of docker and onto podman. The holdout was Taiga which was using docker compose. Despite already deploying a few simpler services with podman, I still didn't know before this how podman does hostnames, how to set up a network with a quadlet, and using PVCs.
My favourite troubleshooting trick of "Delete it and get it to recreate when you restart the thing" turned out to the be the correct choice after a day of furtleing about with #podman networking.

Podman Compose vs Docker Compose https://mydeveloperplanet.com/2023/06/21/podman-compose-vs-docker-compose/
#podman #Docker
Ive built a setup for hosting websites which consists of:
* Host running #microos with #podman
* #Treafik and #sshpiper at the edge
* #Nginx, php-fpm, #mariadb + phpmyadmin + nginx or #postgres + dbadmin, openssh for each site
It actually works quite well, openssh keybased access is to transfer files into the containers, traefik does the reverse proxying.
I'm just wondering if its a sustainable and maintainable setup. Sometimes just going with a "standard" solution seems so much easier.
Estoy experimentando con el CMS #Ghost. Si queréis instalar el contenedor #Docker sobre #Podman en #Fedora, este es el comando que mejor me ha ido hasta ahora:
podman run -d --name nombre-contenedor --userns=keep-id -e NODE_ENV=development -e url=http://localhost:3001 -p 3001:2368 -v /ruta/dentro/de/tu/directorio/personal:/var/lib/ghost/content:Z docker.io/ghost
Podman Quadlets 與 Podman Desktop
➤ 簡化容器管理，提升開發效率
✤ https://podman-desktop.io/blog/podman-quadlet
Podman Quadlets 是一種利用 Systemd 聲明式管理容器的新方法，適用於小型應用或開發環境，避免了 Kubernetes 的複雜性。Podman Desktop 擴展 “Podman Quadlet” 簡化了 Quadlets 的管理，提供視覺化界面來列出、生成、編輯和監控 Quadlets，讓使用者更容易地利用 Systemd 管理容器，實現自動啟動、重啟等功能。
+ 感覺這個 Quadlets 真的解決了在單機開發環境下使用 Kubernetes 的過重問題，Podman Desktop 的整合讓操作更方便了！
+ 終於可以告別繁瑣的指令了，透過圖形界面管理容器，對於新手來說很友善。
#Podman #容器 #Systemd #DevOps
Looking for #Linux #Containers for your CI/CD pipeline? #foundata built a collection of OCI images with
functional systemd (not just a shim!) unprivileged execution support – perfect for tools like #Podman.

Also ideal for #Ansible #Molecule testing, see them in action with a collection: https://github.com/foundata/ansible-collection-acmesh/tree/main/extensions/molecule
New release: #Ansible Skeletons v2.2.0 by https://foundata.com! Now with full Molecule and #Podman support

my #build #container framework:
sudo unshare \
--fork \
--mount \
--uts \
sh -c "
mkdir -p $ROOTFS/proc
mkdir -p $ROOTFS/sys
mkdir -p $ROOTFS/dev
mount -t sysfs /sys $ROOTFS/sys
mount -t proc /proc $ROOTFS/proc
mount --rbind /dev $ROOTFS/dev
hostname $MACHINE
su $USER
export PUAVO_CACHE_PROXY=$PUAVO_CACHE_PROXY
sudo unshare --root $ROOTFS $CMDLINE
"
Been testing out the #virtiofs support now baked into #proxmoxVE. It works, had to do some #selinux adjustments on #fedora to allow my #podman containers to use the mountpoint. Added this policy
```
(allow container_t unlabeled_t ( dir ( read write )))
```
In raw speed it is definitely not a winner - #nfs is easily double the speed. But on this particular VM I don't need the speed - it is nice that this is all self-contained now, and I can actually remove NFS altogether.

#genai #container #podman #rag
Dear #podman users,
am I looking in the wrong spot or is there no systemd timer for "podman image prune"? I thought I had seen something like this in relation to the podman-auto-update service, but fail to find anything on that?
How are people solving the cleanup of images?
