2. postgresql.conf

listen_addresses = '*'

3.docker-compose.yml

postgres:

4. Run docker-compose up

docker-compose -f docker-compose-env.yml up -d

5. Copy file using docker

docker cp pg_hba.conf {container_name}:{location_pg_hba}

6. Kill exisitng postgres

docker-compose -f docker-compose-env.yml kill postgres
