Updates

How the agent updates itself, in stages and with signed releases.

The agent updates itself. There’s nothing to schedule.

How it works

  • The dashboard indicates which version each server should run.
  • New releases go through a test stage before the general stage.
  • Every release has an ed25519-signed manifest with each file’s SHA-256 and size. The updater refuses anything that doesn’t match.
  • The agent is never downgraded by accident.

If something goes wrong

If the new release gets into a crash loop, the agent rolls back to the previous one on its own, without automatically retrying that release.

Install a specific version

curl -fsSL https://get.sentinnel.com.br/install.sh | sudo bash -s -- --version 1.0.12
