database - Postgres服务不断重启

Question

我正在使用postgres服务运行以下docker compose:

version: "3"
services:
  db:
    image: postgres:latest
    restart: always
    container_name: dev_db
    environment:
        - POSTGRES_HOST_AUTH_METHOD = trust
    ports:
    - 5435:5432
    volumes:
    - dev_data:/var/lib/postgresql/data
    - ./dbscripts/postgres:/docker-entrypoint-initdb.d    
volumes:
   dev_data:

但是，我的容器不断重启，当检查日志时，我收到以下消息:

Error: Database is uninitialized and superuser password is not specified.
       You must specify POSTGRES_PASSWORD to a non-empty value for the
       superuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".
       You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all
       connections without a password. This is *not* recommended.
       See PostgreSQL documentation about "trust":
       https://www.postgresql.org/docs/current/auth-trust.html

有人知道这个问题的根源吗？

我认为docker无法读取您的环境变量，因为它的设置不正确。正确的语法是

environment:
    - "POSTGRES_HOST_AUTH_METHOD=trust"
