postgres docker : role "root" does not exist

I am running docker-compose in Github-Action. docker-compose.yml has following service definition for postgres

  postgres:
    container_name: postgres
    image: postgres:12
    restart: always
    volumes:
      - ./test/data/init.sql:/docker-entrypoint-initdb.d/init.sql
    environment:
      POSTGRES_DB: "pgdb"
      POSTGRES_USER: "pguser"
      POSTGRES_PASSWORD: "fr2Yitl4BgX"
    ports:
      - "${POSTGRES_PORT:-5432}:5432"
    healthcheck:
      test: [ "CMD-SHELL", "pg_isready" ]
      interval: 10s
      timeout: 5s
      retries: 5
    networks:
      - "local-api"

But when container start on serf-hosted Github-Action runner, I see following

postgres    | 2021-12-02 19:48:33.537 UTC [414] FATAL:  role "root" does not exist
postgres    | 2021-12-02 19:48:43.984 UTC [424] FATAL:  role "root" does not exist
postgres    | 2021-12-02 19:48:54.265 UTC [433] FATAL:  role "root" does not exist
postgres    | 2021-12-02 19:49:04.410 UTC [443] FATAL:  role "root" does not exist

What is missing here ?

    I’m getting a similar error when trying to run a pg_restore on the postgresql docker container, I had set up postgresql on docker-compose and was trying to restore a db (from my prev postgresql) to it. Just had the initial user as "postgres". Some errors I’d get:

    1. pg_restore: error: connection to server at "localhost" (127.0.0.1), port 5432 failed: FATAL: role "root" does not exist

    2. createuser: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL: role "root" does not exist

    On research I found my pg_restore command needed to specify the User for it to work (tried specifying role, that failed)

    Here’s the working pg_restore command. Perhaps you can do similarly and find a way to specify user in yours?

    #on docker container of psql, command that failed
pg_restore --verbose --clean --no-acl --no-owner -h localhost --role=postgres -d thedbname /home/psql_backups/psql_myapp_220423.dumpbackup

#command that worked
pg_restore --verbose --clean --no-acl --no-owner -h localhost -U postgres -d thedbname /home/psql_backups/psql_myapp_220423.dumpbackup

# lastly (for those doing a pg_restore), from psql commandline, if the restore seems to have worked but don't see data, you may be on the wrong db

    should set POSTGRES_DB and POSTGRES_USER in healthcheck

    healthcheck:
    test: [ "CMD-SHELL", "pg_isready -d $${POSTGRES_DB} -U $${POSTGRES_USER}" ]
