Rootless Podman Quadlet

[jennydaman]

This guide sets up Nextcloud-AIO using Podman in rootless mode and Quadlet behind a reverse proxy.

0. Install Podman

Podman version 4.8.0 or above is required. Older versions of Podman require workarounds, see edit history and discussion below.

1. Set up a reverse proxy

Consult the upstream documentation on how to do this: https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md

An example Caddyfile might look like this:

cloud.example.com {
    reverse_proxy localhost:11000
}


https://cloud.example.com:8443 {
    reverse_proxy localhost:11001 {
        transport http {
            tls_insecure_skip_verify
        }
    }
}

2. Create Systemd Unit File

Create the file ~/.config/containers/systemd/nextcloud-aio-mastercontainer.container with the following content:

[Unit]
Description=Nextcloud AIO Master Container
Documentation=https://github.com/nextcloud/all-in-one/blob/main/docker-rootless.md
After=local-fs.target
Requires=podman.socket

[Container]
ContainerName=nextcloud-aio-mastercontainer
Image=docker.io/nextcloud/all-in-one:latest
PublishPort=127.0.0.1:11001:8080
Volume=nextcloud_aio_mastercontainer:/mnt/docker-aio-config
Volume=/run/user/1001/podman/podman.sock:/var/run/docker.sock:ro
Network=bridge
SecurityLabelDisable=true

Environment=APACHE_PORT=11000
Environment=APACHE_IP_BINDING=127.0.0.1
Environment=WATCHTOWER_DOCKER_SOCKET_PATH=/run/user/1001/podman/podman.sock

[Install]
WantedBy=multi-user.target default.target

Important notes:

• Change /run/user/1001/podman/podman.sock to the path of your Podman socket (podman info --format '{{ .Host.RemoteSocket.Path }}')
• Nextcloud-AIO wants to create and join itself to a network called nextcloud-aio. The option Network=bridge enables this behavior, for details see podman network connect not implemented for slirp4netns containers/podman#19577 (comment)

Also, create the file ~/.config/containers/systemd/nextcloud-aio-mastercontainer.volume:

[Volume]
VolumeName=nextcloud_aio_mastercontainer

3. Start the Services

systemctl --user daemon-reload
systemctl --user start nextcloud-aio-mastercontainer

4. (Optional) Configure Containers to Restart After Reboot

Podman is daemonless so unlike Docker, containers do not restart automatically after reboot.

To enable restart of Podman containers after reboot, see containers/podman#20418 (comment)

5. Business As Usual

Go to https://cloud.example.com:8443 to access the Nextcloud AIO interface and start the Nextcloud server.

Notes

Backups and mastercontainer self-updating might not work, these details have yet to been sorted out.

[jennydaman]

Known issues

I've encountered some problems, however it is unknown whether these are actual bugs related to Podman or just usage errors.

• Built-in backup solution with BorgBackup doesn't really work.
• Master container updates might not work.

For, now, you can manually update the mastercontainer by running

systemctl --user stop nextcloud-aio-mastercontainer.service
podman pull docker.io/nextcloud/all-in-one:latest
systemctl --user start nextcloud-aio-mastercontainer.service

[loeffelpan]

Thanks. Will take some time until FCOS includes this.
I will stay with the monkey patch until then.

[p-fruck]

FYI Podman 4.8.0 has been released a few days ago and is already present in the Fedora 39 repos. Should be only a matter of the CoreOS auto updater to pick that up.
@jennydaman could you please set Podman >= 4.8.0 as the required version in the top level discussion comment? This discussion has become quite complex to follow

[loeffelpan]

@jennydaman Your quick fix doesn't work anymore as @szaimen did this commit: f935993
Maybe you can pull latest commits from upstream to your repo for the fix?

[jennydaman]

@p-fruck and @loeffelpan done

[daniarla]

Is there any workarounds for borgBackup?
Right now it only fails with some error on the directory configured (probably because is running without root permissions) or at least is only what is stated in the logs.

In fact, the database always starts with:
chmod: /var/run/postgresql: Operation not permitted
in the logs

[Verhoeckx]

Will this solution also work with a Podman compose file?

What is de advantage of using a systemd unit file?

[jennydaman]

podman-compose would probably work, how to use it is not documented here.

On the surface level, the main advantage of Quadlet is convenient for people who like systemd and are already comfortable with its syntax.
Other than that, there are a few technical advantages of systemd. For instance, the workflow for lifecycle management (creating, starting, restarting, removing) of podman containers using systemd is better than using podman directly (e.g. systemctl --user stop container both stops and removes the container). For deployment, it's nice to use systemd as the services manager directly because it's what controls everything else. In the case of Nextcloud-AIO, it's possible to specify nextcloud-aio-mastercontainer's dependence on podman.socket and have systemd make things work instead of having to start the socket and nextcloud-aio-mastercontainer manually.

[Verhoeckx]

@jennydaman: thanks for the clarification! I didn't know that it was possible to start containers (with Podman) in unit files! Seems like a clean/efficient solution!

[jennydaman]

Soft reset instructions

systemctl --user stop nextcloud-aio-mastercontainer
containers=$(podman ps -a -f 'name=^nextcloud-aio' --format='{{.Names}}')
podman stop $containers
podman rm $containers
systemctl --user start nextcloud-aio-mastercontainer

[loeffelpan]

Hey, I'm using podman (rootless) in favor of docker on FCOS. My first attempt to get this working like described above ended in an error at domain check. Maybe this is a networking issue as caddy is proxying to host-ip:11000 and the domaincheck-container is only listening at loopback interface.
So I tried to use curl from the host to domaincheck-container and that worked.

Next step was to skip domaincheck but that ended in an Slim Application Error.
Any help would be appreciated. Please feel fre to ask for more information. I will provide what you need.

Bonus:
How should the reverse proxy container be configured to allow domaincheck to be successful?
My Caddy is proxying to the host's IP as loopback with default slirp4netns is not working. Should I use bridged networking for other Containers? By now I understood that's a workaround for AIO, but in containers/podman#19577 they say that bridge networking will be default in podman 5. Any thoughts?

[p-fruck]

Hey there @loeffelpan, are you running behind cloudflare? If so, this might be the reason for your domaincheck issues. When disabling the domaincheck, do the application errors look similar to the ones described in this comment? #3487 (reply in thread) If so, this will be fixed in a newer version of podman. 4.7.0 doesn't contain this fix and I haven't tested 4.7.2 until yet, but I don't think it includes my fix already. Until the fixed podman version is released, you can also patch the source code of your nextcloud AIO as described by @jennydaman here: #3487 (reply in thread)

[kri164]

How do you turn off domaincheck? Can I use this?

Environment=SKIP_DOMAIN_VALIDATION=true

[loeffelpan]

@kri164 Yes. Correct.

[loeffelpan]

@p-fruck You're correct. With slirp4netns loopbacks are difficult. I got this now working with APACHE_IP_BINDING=0.0.0.0.
Thanks.

Is the need of Network=bridge also solved with podman 4.7.2? I understand containers/podman#19577 that podman network connect for slirp4netns will not be fixed? So bridged network is simply needed, not longer a workaround.

If I an correct this should be mentioned in the initial post for anyone who is joining this discussion.

[p-fruck]

Interestingly, my local setup is created with the network in bridge mode by default (podman 4.7.0). Might have to do with my system default (Fedora CoreOS 39 beta), though I did not check any further. @loeffelpan what exactly would you like to mention? Afaict the default network mode of podman might deviate depending on how the given linux distribution packages podman, so I would simply mention that bridge network must be used (as already done by @jennydaman )

[loeffelpan]

I think this should not differ between distros. I'm also on podman 4.7.0 with FCOS 38.
And for rootless containers slirp4netns is default. bridge is default for rootless containers. This is also mentioned in the docs of podman run:
slirp4netns[:OPTIONS,…]: use slirp4netns(1) to create a user network stack. This is the default for rootless containers.
bridge[:OPTIONS,…]: Create a network stack on the default bridge. This is the default for rootful containers.

I was pointing to this one from the initial post.

Important notes:

• Change /run/user/1001/podman/podman.sock to the path of your Podman socket (podman info --format '{{ .Host.RemoteSocket.Path }}')
• Network=bridge is a necessary workaround for a slirp4netns bug

There is Network=bridge mentioned as a workaround for a bug. But it turned out that this is not a bug and will not be changed.

Allover, I think @jennydaman should modify this as simply needed and not a workaround. Regardless of distro/package differences or rootful/rootless setups.

[p-fruck]

This error seems like its the same I mentioned above, related to podman.

[loeffelpan]

I'm confused that this question has not beeing asked. Maybe I missed something.
With only the mastercontainer as quadlet unit file. All the other nextcloud containers are gone after reboot.
How to start/deploy them in this setup?

[loeffelpan]

Thats quite a good idea. Thanks! @szaimen
Another option would be something like this as cronjob (not tested yet).

@reboot containers=$(podman ps -a -f 'name=^nextcloud-aio' --format='{{.Names}}'); podman start $containers

[jennydaman]

@loeffelpan and @szaimen thanks for bringing podman-restart.service to my attention, I've made a comment to upstream containers/podman#20418 (comment) and also modified the instructions here.

[loeffelpan]

In my case (on FCOS) podman-restart.service is disabled on any reboot.
@p-fruck You are on FCOS as well. Is this default behaviour and I have to set it to enable with ignition?

[p-fruck]

Can confirm that its disabled by default. This should not be anything CoreOS specific though. You can enable it in the ignition file for new installations, but a simple systemctl --user enable podman-restart.service should be fine too, since the ignition is only applied once.

[loeffelpan]

I did this. But for some reason (maybe zincati update finaliziation?) its disabled again. Any idea?

[loeffelpan]

Anyone using collabora in this setup?
I tried but got tons of errors and login page was loading infinite.

Without collabora nextcloud is working fine.

[p-fruck]

Not using collabora yet but I had some DNS issues trying to access my IdP when configuring OIDC for SSO. Can you try to curl https://kbw3.de and nslookup kbw3.de within your nextcloud-aio-nextcloud container? For me, the DNS started working again after invoking nslookup in the container manually, though this might have been an issue with my setup...

[loeffelpan]

curl https://kbw3.de from inside the nextcloud container is working fine. Seems not to be an DNS issue.

[p-fruck]

It depends. For me curl was working but the php request didn't until I executed nslookup for the domain once. Apparently the dns entry had to be cached first for some odd reason

[loeffelpan]

To solve this I started another discussion which brought me on the right track.
It seem that Collabora needs CAP_MKNOD to run. Unfortunately docker provides this capability by default. Podman does not.
But even when @szaimen adds this capability to his API commands for creating the collabora container it still needs root to use this capability.

So running collabora in our rootless setup isn't possible right now - regardless docker or podman.
And running collabora in AIO in a rootful setup is only possible with docker, not with podman as CAP_MKNOD is missing so far.

Is SELinux enabled on Silverblue? As it's basically Fedora, it should.
On FCOS I saw some AVC deny messages in the audit.log when sharing a socket to a container. My setup runs in permissive mode by now due to other issues and it works. I did not figure it out how to modify SELinux to allow sharing sockets with containers.

[szaimen]

Maybe this helps? https://github.com/nextcloud/all-in-one#are-there-known-problems-when-selinux-is-enabled

[loeffelpan]

Indeed that would help. But disabling security is not my way to go. I'm looking for a way to allow socket access by rule for SELinux instead.

[p-fruck]

Honestly, I feel like running with SELinux in enforcing mode and disabling security opts for the master container only might be the way to go. If you want to build your own SELinux policy, maybe this reply can help ;)

[kri164]

Some notes from my last install. Hope it helps.

cgroups

Running containers as rootless requires cgroups version 2. Version 1 or hybrid mode v1/v2 doesnt work. Check the status
mount | grep '^cgroup' | awk '{print $1}' | uniq
To change this add a kernel command line parameter to the boot loader and reboot
systemd.unified_cgroup_hierarchy=1

SELinux

Check the status with command
sestatus
If enabled you should mount volumes with big Z letter as option
Volume=/run/user/1000/podman/podman.sock:/var/run/docker.sock:Z

Netavark

Todays versions of Podman comes with Netavark module, but existing installations are configured for CNI. If you have problems with intercontainer DNS resolution, switch it.
Check current status
podman info | grep networkBackend
then install "aardvark-dns netavark" packages
and finally switch
podman system reset
WARNING: It will complete WIPE of your container environment, all networks, volumes, images will be erased!

Backup restore

Backup restore doesnt work during initial installation. Error is "Permission denied". Not sure if common bug or rootless install only. As a workaround, you can symlink backup directory to /tmp and use it for import
ln -s /home/aio/backup /tmp/backup
Regular backup works fine.

[bennypowers]

Thank you for these instructions. I was able to get this working through cloudflare tunnel by adding a "Bypass - include everyone" rule for the zero trust app. (Allow - include everyone did not work because it continued to ask for cloudflare OTP, which broke the mobile apps with "Malformed server configuration").

I will need to make modifications to config.php, namely default_phone_region and perhaps also trusted_proxies. Is there an environment variable I can declare in the nextcloud-aio-mastercontainer.container unit which will set those?

[p-fruck]

Hi, I don't think so but you could use some kind of script/init-container which executes the occ command as described here

[bennypowers]

For future reference, I solved this (from the host OS) by editing the file at ~/.local/share/containers/storage/volumes/nextcloud_aio_nextcloud/_data/config/config.php

[ghost]

Fedora 39 here.
It seems I need to put the capital Z: Volume=/run/user/1000/podman/podman.sock:/var/run/docker.sock:Z
However SELinux is getting in the way:

Maybe this one help https://github.com/dpw/selinux-dockersock

[p-fruck]

In case you do not want to deal with SELinux policies, you might want disable SELinux labeling for socket as explained in the docs

[ghost]

@p-fruck That seems to work.
So for Fedora you also need to set: SecurityLabelDisable=true

Any way to create a policy on Fedora Core OS? I can't figure it out.

[p-fruck]

I think this question should be asked in the podman discussions. There official answer seems to be disabling SELinux labels for the specified container though. Feel free to link to link your discussion here ;)

[loeffelpan]

On any mastercontainer update I got this error (in the logs of watchtower container):
crun: cannot set memory swappiness with cgroupv2

Same on starting newly created mastercontainer.
Any idea?

[loeffelpan]

Am I the only one with problems on updates (of mastercontainer or any other container of aio)?

[bennypowers]

for me, at the moment, automated updates always fail to restart containers, and occasionally crash the ncaio container as well.

[loeffelpan]

Yeah. Containers can be created but not started. Seems due to the above error concerning memory swapiness.
I found this issue but no solution.
containers/podman#13916

Maybe someone can take a look?

[bennypowers]

I'm not sure that I have the same issue as you, although the symptoms are similar (ncaio crashing or not starting containers)

here are my latest watchtower logs. note the date is feb 2 although just this morning (feb 4) I experienced aio stopping all containers and failing to start them

If the problem is docker.io limits, I can temporarily solve by authenticating, but it seems like something deeper is going on here

[loeffelpan]

You're right. Seems to be not the same error.
Mine is clearly related to swapiness like in the mentioned issue.

[daniarla]

Hey!
After a couple of days fighting with podman and nextcloud-aio on debian and getting the error:

NOTICE: PHP message: Could not start domaincheck container: Could not start container nextcloud-aio-domaincheck: Server error: `POST http://localhost/v1.41/containers/create?name=nextcloud-aio-domaincheck` resulted in a `500 Internal Server Error` response:

{"cause":"executable file not found in $PATH","message":"container create: lookup init binary: exec: \"catatonit\": exec (truncated...)

It seems that for some reason podman needs catatonit in order to create other containers. I didn't know that it could have saved a couple of days of troubleshooting.

I'm just documenting it here in case that someone has the same problem!

[Lippiece]

Trying this on Arch Linux arm on RPi 5 (it may or may not be the case) is and I get the following:

When connected to localhost:11001: Slim Application Error. Then after page refresh: Domaincheck container is not running.

In the journal:

Also on podman start nextcloud-aio-domaincheck:

[dsreyes1014]

How are you guys running caddy with this setup ? Are you running it with podman-rootless or with podman-root?

[MastaG]

I'm using nginx as the reverse proxy and ssl offloader.
The problem I'm facing is that the public IP used by nginx for listening on port 80 and 443 resides on the same server.
When I enter the nextcloud container with: podman exec -it nextcloud-aio-nextcloud sh
I cannot connect with https://my_nextcloud_domain/ because the public IP lives on the same host as my rootless containers.
I think that's a limitation of podman's bridge driver?
Or did somebody found a workaround for this?

[Schlunze]

i had success by adding npm proxy environment variables.

For some reason, curl fails when run inside the container, but curl -4 works normally. As such:
NOTICE: PHP message: Could not get digest of container nextcloud/aio-domaincheck:latest cURL error 7: Failed to connect to auth.docker.io port 443 after 4003 ms: Couldn't connect to server (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://auth.docker.io/token?service=registry.docker.io&scope=repository:nextcloud/aio-domaincheck:pull
I suspect this is due to some ipv6 misconfiguration. Can someone hint me where to look?

[Lippiece]

Resolved by adding

[Container]
...
DNS=8.8.8.8

[Lippiece]

It would appear that this is not propagated to the child containers. Any ideas on how to change DNS for all the Nextcloud containers?

Edit: Ah, no matter, this is resolved by changing DNS for the machine and/or router.

[Lippiece]

[septatrix]

That seems unrelated and more like a corrupt disk

[DWW256]

Do I have to use a reverse proxy? Or can I just publish the container to 8443 directly by changing to

PublishPort=127.0.0.1:8443:8080

...

Environment=APACHE_PORT=8443

as the Nextcloud AIO documentation defaults to doing?

[rexbron]

After a server reboot, I could not get the AIO container up with:

Trying to fix docker.sock permissions internally...
Adding internal www-data to group root
Docker socket is not readable by the www-data user. Cannot continue

The permissions on /run/user/1000/podman/podman.sock was 600, and needs to be 660.

No idea why a reboot changed that... wasted 4 hours on this...

[Lippiece]

Is there anything useful in systemctl --user status podman.socket? Does the socket unit look like it's described in podman docs? Are permissions in the parent folders (/run/user/1000/podman/ and /run/user/1000/) correct? I also recommend docs on rootless setup, just to be sure.

If nothing helps, does chmod 660 /run/user/1000/podman/podman.sock resolve this? If so, one workaround may be to run this on user session start.

running the chmod does fix this. What I don't know is why it changes.

[rexbron]

After updating the mastercontainer, I encountered the same socket permission error. podman.sock was 660

Adding UserNS=keep-id changed the error to

Cannot connect to the docker socket. Cannot proceed.
nextcloud-aio-mastercontainer[1957555]: Did you maybe remove group read permissions for the docker socket? AIO needs them in order to access the docker socket.

chmod 777 /run/user/1000/podman.sock got the mastercontainer booted but is probably a bad idea.

Suggestions for further investigation?

[ignaciolg]

I've AIO working, but every time that I reboot my server, the nextcloud containers do not start, even if AIO is up&&running.

Is there a way to auto run the "child" containers without the need to access AIO page and press the button?

[ignaciolg]

seems to need to write custom quadlets in podman to get this up&&running after each reboot

Re-read the instructions.

Specifically:

Change /run/user/1001/podman/podman.sock to the path of your Podman socket (podman info --format '{{ .Host.RemoteSocket.Path }}')

There is no --volume /var/run/docker.sock:/var/run/docker.sock:ro with podman.

[vwbusguy]

You actually can do this if you enable to podman socket as root and having the podman-docker package installed or just point directly to the podman socket. The problem seems to be that the socket doesn't work with SELinux enabled, even with passing :Z, so you need to --security-opt label:disable.

[vwbusguy]

Here's my currently working example:

sudo podman run --init --sig-proxy=false --name nextcloud-aio-mastercontainer --restart always -eAPACHE_PORT=8081 --publish 80:80 --publish 8080:8080 --publish 8443:8443 --replace  --security-opt label:disable --volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config --volume /run/podman/podman.sock:/var/run/docker.sock:ro nextcloud/all-in-one:latest

It's working for me --security-opt label:disable , Thank you @vwbusguy

[vwbusguy]

For context, I believe this is similar to why you also need to disable SELinux when you're doing podman in Kubernetes as well. I realize that it isn't ideal for everyone, but it is a reality for some similar podman deployment operations and not only a Nextcloud AIO issue.

(In this case, you do not need to disable SELinux on the host, but just disable it in the specific podman run!)

[Macr0Nerd]

Hello! I'm attempting to run Nextcloud in this fashion but I have some concerns. For context, my environment is is using Podman Quadlets on a Fedora VM. Users and permissions are managed using FreeIPA. All persistent volumes are stored on NFS shares that are also Kerberized. I am running this as a specific user using the above configurations (although I am heavily considering the manual installation in a Pod to allow this to run rootless under root). The reason I bring this up is that I can't actually start the Nextcloud container itself as it can't chown the data directory to www-data:root. This is because the data directory is on an NFS that has IDs mapped, and if I attempt to change the ownership to www-data:NCDATA_GID it ends up as nobody:root in the container. I will include my configurations below, but I believe I need more idmaps but I'm not entirely sure. The Nextcloud container runs under the service user ncdata which is centrally managed.

Note: nextcloud_data_dir was just an attempt to get perms right. That's why it hasn't been configured yet

Ok I think I just need to map UID 33 into the container, but I'm figuring out how to get NFS to export UID 33.

[vwbusguy]

Ref. https://www.redhat.com/sysadmin/rootless-podman-nfs but you have an extra complexity with sssd.

Also, this discussion: containers/podman#16018

[rgolangh]

I created a tool to manage podman and quadlets from repositories, and with it this installation can be run like so:

pq install nextcloud

The tool is using git repositories with folders containing all the quadlet files. The default the tool works with is https://github.com/rgolangh/podman-quadlets , but you can use your own of course.

If you're interested please check-out https://github.com/rgolangh/pq - PRs or issues/discussions and feedback are welcomed.

[vwbusguy]

This is cool - it seems like a sort of helm chart way to deploy things with podman. Do you also have a way to update the existing deployment with newer image refs?

[rgolangh]

the beauty is that podman does that for you using podman auto-update.service and to opt-in just add this to the quadlet file:

[container]
AutoUpdate=registry

This should result in a label on the container podman creates to be picked up by auto-update.
See https://docs.podman.io/en/latest/markdown/podman-auto-update.1.html

[vwbusguy]

Excellent work! I love that you also have a repo ref for Valkey as well!

When going into https://127.0.0.1:8443 I get an SSL_ERROR_INTERNAL_ERROR_ALERT error. Not sure what to do. I'm not sure how to get my custom Caddyfile in there tbh.

[rexbron]

Can you post your caddyfile?

After updating to version 30.0.2, the AppAPI feature is flooding my logs with errors related to accessing the docker.sock.

[app_api] Error: Could not connect to Docker daemon
	POST /apps/app_api/daemons/verify_connection
	from <redacted> at Dec 1, 2024, 11:22:38 AM

Suggestions? Disable AppAPI? Point it in the right direction somehow?

[vwbusguy]

Install podman-docker and system enable --now podman.socket should get that to work

[rexbron]

Both were already installed prior to this update. Are you suggesting podman.socket needs to be enabled for the root user?

podman.socket is enabled as the podman user. My intent is to use podman as a rootless user.

podman.socket is enabled as the podman user. My intent is to use podman as a rootless user.

Do you have DOCKER_HOST set?

$ env | grep DOCKER_HOST
DOCKER_HOST=unix:///run/user/1000/podman/podman.sock

[rgolangh]

It is worth making sure podman.socket is active as the user

systemctl is-active --user  podman.socket 

[Extarys]

Anyone managed to make onlyoffice work? I cannot access the host from within the container.
curl -I https://host... is unreachable from within the mastercontainer.
