Issues when changing password in .env and docker-compose.yml

[Lukas Köllner]

Everything worked well I cloned the repository and followerd the setup steps but because I changed the postgres password when running the third setup set I ran into an authentication error for postgres.

PG::ConnectionBad: FATAL: password authentication failed for user "postgres"

I assume I have to change the password somewhere else. I just can't figure out where that is.

I would be grateful if anyone could help me

Assuming you have a .env file in the root folder, update the PGPASSWORD variable in there to match the value of the password in the database's service definition in docker-compose.yml (https://github.com/ryanwi/rails7-on-docker/blob/main/docker-compose.yml#L22)

You can also try hardcoding directly in the rails database config as a first step to make sure things are working https://github.com/ryanwi/rails7-on-docker/blob/main/config/database.yml#L32.

I got it working by changing the password in the .env and docker-compose.yml file. But I also had to log in to postgres using the old password and altering it from there

I got it to work, by:

1. Change password in .env file
2. Change password in docker-compose.yml
3. Remove docker volume rails7-on-docker_pg_data (docker volume rm [container ID])
4. Start app normally with docker compose up
5. Run now advised docker compose run --rm web bin/rails db:setup
