This is my docker-compose file :

Answer 1

Modify your docker-compose.yml file as below:

version: '2'
services:
  db.postgres:
    container_name: db.postgres
    image: postgres:10
    environment:
      - POSTGRES_USER=myuser
      - POSTGRES_PASSWORD=myuserpassword
      - POSTGRES_DB=mydb
    ports:
      - '5432:5432'
    volumes:
      - ./pgdata:/var/lib/postgresql/data

Then drop your current data entirely and re-run docker-compose up.
