root password for setting up.

Maybe you could name your env var differently to make its use more obvious, like PT_ROOT_PASSWORD? Otherwise, admins may not know if it’s DB password[1] or root account password.

[1] yeah, I know, it’s dumb because that password is in config file but still, it’s better to have obvious env var.

That's the right place to go 👍

much like what @ldidry said, I would rename the environment variable to something even more explicity. PT_INITIAL_ROOT_PASSWORD seems fitting, because:

• we make explicit the scope (PT and not Postgres)
• we make explicit this only applies at the initialization
• we make explicit the user name

Additionally I would add a note to:

• https://docs.joinpeertube.org/lang/en/docs/configuration.html
• https://github.com/Chocobozzz/PeerTube/blob/develop/support/doc/production.md#administrator

@ALL: Thanks for your review! ☺

@ldidry I will make a change, PASSWORD was a "placeholder" name, is really better PT_INITIAL_ROOT_PASSWORD.

@rigelk : Thanks for the pointers to the documentation.

Is it a good idea to let run password validation on this?

Note: The validation is about pasword length https://github.com/Chocobozzz/PeerTube/blob/develop/server/helpers/custom-validators/users.ts#L10

Apart from a typo, LGTM.

update:

• Fixed some typo.
• Fixed style, removing useless semicolon
