FR: Allow setting SSM parameter for state in Docker

[jaxxstorm]

What are you trying to do?

I'm trying to run a host in AWS Fargate, using Docker. tailscaled supports using an AWS SSM parameter for storing state, but there's no env var that exists for using it, unlike kubernetes.

How should we solve this?

Add an env var to container boot that allows setting the SSM parameter

What is the impact of not solving this?

You can get around this by using EXTRA_ARGS but it's not ideal

Anything else?

No response

As a work around you can set TS_TAILSCALED_EXTRA_ARGS="--state=arn:aws:ssm:..."
