Updating server

[Helixoo]

Hello, I updated my server with sudo apt update && sudo apt upgrade -y and my server crashed and I restore it from the last snapshot. What can I do for updating the system without crashing the server? Or is it updating when its compatible with dokploy?

Hi @Helixoo! I'm Dosu and I’m helping the dokploy team.

@Helixoo This is a common issue — running apt upgrade can update Docker Engine from v27.x to v29.x, which breaks Traefik routing because Docker 29.x raised its minimum API version requirement . Kernel updates can also trigger reboots that cause container networking failures [1].

To safely update your system without breaking Dokploy:

1. Pin Docker packages so apt upgrade doesn't touch them:

   sudo apt-mark hold docker-ce docker-ce-cli containerd.io

   This lets you update everything else safely .

2. Run upgrades selectively — after apt update, review what will be upgraded with apt list --upgradable before running apt upgrade.

3. Take a snapshot before upgrading (which you're already doing — good practice).

4. If Docker does get upgraded to v29.x, the fix is to update Traefik to v3.6.7+ which supports the newer Docker API version .

Dokploy itself doesn't manage or schedule OS updates — that's up to you. The key takeaway is to hold Docker packages at their current version and only upgrade Docker intentionally when you've confirmed Traefik compatibility.

To reply, just mention @dosu.
