The Docker image for Thingsboard with Cassandra (thingsboard/tb-cassandra) also has a Postgres database to store metadata among other things.

I need to connect to this Postgres database from outside the container with a monitoring and administration tool. For that, I need the user and password that were provided for the database when the image was created, and I couldn't find this information in the Thingsboard documentation. I don't want to change the credentials because that might cause problems with the other components of the Docker container.

Does anybody know this user/password combination?

CodePudding user response：

According to thingsboard compose file:

    environment:
      POSTGRES_DB: thingsboard
      POSTGRES_PASSWORD: postgres

And according to Postgress:

POSTGRES_USER

This optional environment variable is used in conjunction with POSTGRES_PASSWORD to set a user and its password. This variable will create the specified user with superuser power and a database with the same name. If it is not specified, then the default user of postgres will be used.

So user/password should be postres/postgres.
