How to update Hawser?

[Paebbels]

The installation instructions are these:

curl -fsSL https://raw.githubusercontent.com/Finsys/hawser/main/scripts/install.sh | bash

As I noticed, this method isn't setting up a Debian package repository.
How to (automatically) update Hawser?

---

I suspect running the install.sh again will overwrite my settings e.g. the token in /etc/hawser/config.

Is there an update.sh or is there an setting to install.sh for updating?

Alternatively, running Hawser via Docker is offered. This is not a practical solution, because it requires GitLab SSH runners besides the normal Docker runners on every machine to deploy Hawser (>50 in my case).

Moreover, the token is handed over via environment variable, this is unsafe.

I just tried running the install script again and it left my token intact.

I've read the install.sh:

• There is a check for an existing configuration file:
  if [ ! -f "$CONFIG_DIR/config" ]; then
• If the configuration file template changes, a user won't notice.
• It doesn't check if /etc/systemd/system/hawser.service was modified by the user.
  Unlikely but possible. A warning should be printed.
• It doesn't stop hawser before modifications.
• It doesn't start hawser after modifications.
