Docker dpage/pgadmin4错误：指定的用户不存在

Question

这是docker-compose.yml文件：

version: '3'

services:
############################
# Setup database container #
############################
  postgres_db:
    image: postgres
    restart: always
    ports:
      - ${POSTGRES_PORT}:${POSTGRES_PORT}
    environment: 
      - POSTGRES_USER=${POSTGRES_USER}
      - POSTGRES_PASSWORD=${POSTGRES_PASSWORD}
      - PGDATA=/var/lib/postgresql/data/pgdata
      - POSTGRES_DB=${POSTGRES_DB}
    volumes:
      - ./data:/var/lib/postgresql/data 
    networks:
      - db_network

  pgadmin:
    image: dpage/pgadmin4:4.19
    restart: always
    ports:
      - 8001:8080/tcp
    environment: 
      - PGADMIN_LISTEN_ADDRESS=0.0.0.0
      - PGADMIN_LISTEN_PORT=8080
      - PGADMIN_DEFAULT_EMAIL=${PGADMIN_DEFAULT_EMAIL}
      - PGADMIN_DEFAULT_PASSWORD=${PGADMIN_DEFAULT_PASSWORD}
    networks:
      - db_network

networks: 
  db_network:
    driver: bridge

.env同一目录下有一个文件。

# The above refers to the name of the postgres container since using docker-compose
# This is because docker-compose creates a user-defined network. Kubernetes also does this.
POSTGRES_PORT=5432
POSTGRES_USER=website
POSTGRES_PASSWORD=website
POSTGRES_DB=wikifakes_main
PGADMIN_DEFAULT_EMAIL=info@my-website.com
PGADMIN_DEFAULT_PASSWORD=my-secure-password 

当执行docker-compose up --builddocker start 时，我可以通过 访问 pgAdmin4 网站localhost:8001。但是，输入凭据后，我收到以下响应：

指定用户不存在

为什么指定的用户不存在，如何更改环境才能登录？

pgadmin4不过，通过创建的 docker登录docker run --rm -e PGADMIN_DEFAULT_EMAIL="info@my-website.com" -e PGADMIN_DEFAULT_PASSWORD="my-secure-password" -p 8001:80 dpage/pgadmin4可以正常工作。

Answer 1

添加tty: true到pgadmindocker-compose.yml 文件中的服务。

  pgadmin:
    image: dpage/pgadmin4:4.19
    restart: always
    ports:
      - 8001:8080/tcp
    environment: 
      - PGADMIN_LISTEN_ADDRESS=0.0.0.0
      - PGADMIN_LISTEN_PORT=8080
      - PGADMIN_DEFAULT_EMAIL=${PGADMIN_DEFAULT_EMAIL}
      - PGADMIN_DEFAULT_PASSWORD=${PGADMIN_DEFAULT_PASSWORD}
    networks:
      - db_network
    # ADD THIS LINE
    tty: true

所以完整的文件将如下所示：

version: '3'

services:
############################

    image: postgres
    restart: always
    ports:

      - POSTGRES_PASSWORD=${POSTGRES_PASSWORD}
      - PGDATA=/var/lib/postgresql/data/pgdata
      - POSTGRES_DB=${POSTGRES_DB}
    volumes:
      - ./data:/var/lib/postgresql/data 
    networks:
      - db_network

      - PGADMIN_DEFAULT_PASSWORD=${PGADMIN_DEFAULT_PASSWORD}

    # ADD THIS LINE, TO BE ABLE TO LOGIN
    tty: true
