连接到Docker容器中的Postgres时出现身份验证错误

Question

I'm getting the following error when I try to connect to a Postgres database inside a Docker container. I'm using pgAdmin 4 on windows as my client.

Password does not match for user "postgres".

My docker-compose file is as follows:

version: "3"
services:
  db:
    image: postgres
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
      - POSTGRES_DB=postgres
    ports:
      - "5433:5432"
    volumes:
      - pgdata:/var/lib/postgresql/data
volumes: 
  pgdata:

Not sure what I'm doing wrong. The file states that the username and password are both postgres . I was able to connect when I just docker run the image. Now I'm using the compose file I seem to be getting this problem.

Answer 1

Fixed by doing the following:

• Stopped container.
• Removed container.
• Removed volume.

Volume must have contained previous configuration.
