How do you guys handle reverse proxies in rootless containers? (lemmy.world)

I've been trying to migrate my services over to rootless Podman containers for a while now and I keep running into weird issues that always make me go back to rootful. This past weekend I almost had it all working until I realized that my reverse proxy (Nginx Proxy Manager) wasn't passing the real source IP of client requests down to my other containers. This meant that all my containers were seeing requests coming solely from the IP address of the reverse proxy container, which breaks things like Nextcloud brute force protection, etc. It's apparently due to this Podman bug: https://github.com/containers/podman/issues/8193

This is the last step before I can finally switch to rootless, so it makes me wonder what all you self-hosters out there are doing with your rootless setups. I can't be the only one running into this issue right?

If anyone's curious, my setup consists of several docker-compose files, each handling a different service. Each service has its own dedicated Podman network, but only the proxy container connects to all of them to serve outside requests. This way each service is separated from each other and the only ingress from the outside is via the proxy container. I can also easily have duplicate instances of the same service without having to worry about port collisions, etc. Not being able to see real client IP really sucks in this situation.

Anyone else unable to log out of Plasma 6? (lemmy.world)

On one of my machines, I am completely unable to log out. The behavior is slightly different depending on whether I am in Wayland or X11.

Wayland

  1. Clicking log out and then OK in the log out window brings me back to the desktop.
  2. Doing this again does the same thing
  3. Clicking log out for a third time does nothing

X11

  1. Clicking log out will lead me to a black screen with just my mouse cursor.

In my journalctl logs, I see:

PSA: Docker nukes your firewall rules and replaces them with its own. in c/selfhosted@lemmy.world
[-] Molecular0079@lemmy.world 67 points 6 months ago

If you use firewalld, both docker and podman apply rules in a special zone separate from your main one.

That being said, podman is great. Podman in rootful mode, along with podman-docker and docker-compose, is basically a drop-in replacement for Docker.

What are some KVM-over-IP or equivalent solutions you guys would recommend for guaranteed remote access and remote power cycle? (lemmy.world)
submitted 11 months ago by Molecular0079@lemmy.world to c/selfhosted@lemmy.world

Currently, I have SSH, VNC, and Cockpit setup on my home NAS, but I have run into situations where I lose remote access because I did something stupid to the network connection or some update broke the boot process, causing it to get stuck in the BIOS or bootloader.

I am looking for a separate device that will allow me to not only access the NAS as if I had another keyboard, mouse, and monitor present, but also let's me power cycle in the case of extreme situations (hard freeze, etc.). Some googling has turned up the term KVM-over-IP, but I was wondering if any of you guys have any trustworthy recommendations.

Patch 2 seems to have drastically slowed down the Vulkan Renderer. Before I was able to get 80-110FPS in the Druid Grove, but now I am only getting 50fps. DX11 seems fine though, but I prefer using Vulkan since I am on Linux.

[SOLVED] If I am using the SWAG proxy in front of a Nextcloud instance, is it safe to ignore some of the warnings in the admin page? (lemmy.world)
submitted 1 year ago* (last edited 1 year ago) by Molecular0079@lemmy.world to c/selfhosted@lemmy.world
2 comments fedilink

I am using one of the official Nextcloud docker-compose files to setup an instance behind a SWAG reverse proxy. SWAG is handling SSL and forwarding requests to Nextcloud on port 80 over a Docker network. Whenever I go to the Overview tab in the Admin settings, I see this security warning:

    The "X-Robots-Tag" HTTP header is not set to "noindex, nofollow". This is a potential security or privacy risk, as it is recommended to adjust this setting accordingly.

I have X-Robots-Tag set in SWAG. Is it safe to ignore this warning? I am assuming that Nextcloud is complaining about this because it still thinks its communicating over an insecured port 80 and not aware of the fact that its only talking via SWAG. Maybe I am wrong though. I wanted to double check and see if there was anything else I needed to do to secure my instance.

SOLVED: Turns out Nextcloud is just picky with what's in X-Robots-Tag. I had set it to SWAG's recommended setting of noindex, nofollow, nosnippet, noarchive, but Nextcloud expects noindex, nofollow.

I've been messing around with podman in Arch and porting my self-hosted services over to it. However, it's been finicky and I am wondering if anybody here could help me out with a few things.

  1. Some of my containers aren't getting properly started up by podman-restart.service on system reboot. I realized they were the ones that depended on my slow external BTRFS drive. Currently its mounted with x-systemd.automount,x-systemd.device-timeout=5 so that it doesn't hang up the boot if I disconnect it, but it seems like Podman doesn't like this. If I remove the systemd options the containers properly boot up automatically, but I risk boot hangs if the drive ever gets disconnected from my system. I have already tried x-systemd.before=podman-restart.service and x-systemd.required-by=podman-restart.service, and even tried increasing the device-timeout to no avail.

When it attempts to start the container, I see this in journalctl:

All the containers are started using docker-compose with podman-docker if that's relevant.

Any help appreciated!

EDIT: So it seems like podman really doesn't like systemd automount. Switching to nofail, x-systemd.before=podman-restart.service seems like a decent workaround if anyone's interested.

I've already tried adding ::/0 to the AllowedIPs option and IPv6 is listed as disabled in the NetworkManager profile.

The problem with PeerTube is that there's no built-in way for creators to get paid. If there are no ads or sponsors, then the only alternative is some kind of value for value system like what Podcasting 2.0 has. Until some kind of well integrated funding system gets built for PeerTube, creators really are not going to be incentivized to publish stuff on the platform.
