how to use the docker image?

[christf]

when running the command as documented in the readme, I get:

docker logs signal-cli
Failed to read local accounts list

What do I need to do to run signal-cli from docker (the flatpak works for me at the moment, I would just prefer to run it somewhere that is not my desktop)?

You need to make sure that the docker user in the container has write access to the volume you're passing to the container. Alternatively run signal-cli inside the container as root: -u root.
