[Docs]: clarification on hashed password

[j4ys0n]

What is your suggestion?

Please mention that if you're entering the hashed password in a docker-compose yaml file that the $ need to be escaped like $$ or else docker will interpret them as variable markers. Also mention that the password should not be contained in quotes.

How will this improve the docs?

Hashed password will work with more run environments

Are you interested in submitting a PR for this?

Sure

That is not code-server specific and already described here: https://docs.docker.com/compose/compose-file/12-interpolation/

[j4ys0n]

Yes, you are correct. It would be nice to include that information as it is relevant. Just my opinion.

Maybe this was added later, but we do mention this in the docs at the moment.

Edit: yeah it was added later #6671
