我使用這樣的 docker-compose.yml

  postgres_container:
    container_name: postgres_container
    image: postgres:13.3
    environment:
      - POSTGRES_DB=$POSTGRES_NAME_DB
      - POSTGRES_USER=$POSTGRES_USER
      - POSTGRES_PASSWORD=$POSTGRES_PASSWORD
      - PGDATA=$POSTGRES_PGDATA
    ports:
      - $POSTGRES_LOCAL_PORT:$POSTGRES_DOCKER_PORT
    user: postgres
    volumes:
      - ./postgres/scripts/init.sql:/docker-entrypoint-initdb.d/init.sql
      - .:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U admin -d pgdb"]
      interval: 10s
      timeout: 5s
      retries: 5
      start_period: 10s
    restart: unless-stopped
    deploy:
      resources:
        limits:
          cpus: '1'
          memory: 4G

其中$POSTGRES_PGDATA=/var/lib/postgresql/data/pgdata

Answer 1

我添加 pgdata 卷

- pgdata:/var/lib/postgresql/data

並添加

volumes:
  pgdata:

這個對我有用

Answer 2

我在 docker-compose.yml 的最后部分添加卷

version: '3.3'
services:
postgres:
    image: postgres:13
    environment:
       - POSTGRES_DB=mybd
       - POSTGRES_USER=myuser
       - POSTGRES_PASSWORD=passuser
    ports:
      - 5432:5432
    volumes:
      - postgres_data:/var/lib/postgresql/data
volumes:
postgres_data:
