How to update agents?

[LordShadowen]

Apologies if I'm missing something obvious - how are agents (PVE and Docker) updated?

I've just updated Pulse itself for the first time after the original installation to 4.31.0, and that went fine.
But as far as I can tell all the agents remained unchanged, and I don't see any reference on the documentation about this. Only how to install or remove.
I guess I could just redo the installation, but that involves creating a new token... which should not be needed, right?

Actually, come to think of it... have the agents been updated? Is there always a newer version bundled with the Pulse update? Or are they on a different version track? I'm quite unclear about this...

Docker agent auto-updates daily (and on restart) by pulling the latest binary from your Pulse server unless --no-auto-update/PULSE_NO_AUTO_UPDATE is set. For the containerized agent image (it sets PULSE_NO_AUTO_UPDATE=true), redeploy the container to get the new binary or flip that env var back to allow self-updates.

Host/PVE agent doesn’t self-update. Rerun install-host-agent.sh from your Pulse server with the same URL/token; it downloads the current binary and restarts the service. No token rotation is needed unless you want to rotate credentials.

If we ship a breaking or urgent agent change, we’ll call it out in the release notes; you’d just rerun the host installer or redeploy the Docker agent container where auto-update is disabled.
