docker-编写redis和redis命令

Question

我使用windows docker工具箱，我对我缺少的东西感到困惑。我想使用redis指挥官(https://www.npmjs.com/package/redis-commander)和一个来自docker hub的docker图像redis。

我使用了上面链接中的docker-compose.yml：

version: '3'
services:
  redis:
    container_name: redis
    hostname: redis
    image: redis

  redis-commander:
    container_name: redis-commander
    hostname: redis-commander
    image: rediscommander/redis-commander:latest
    build: .
    restart: always
    environment:
    - REDIS_HOSTS=local:redis:6379
    ports:
    - 8081:8081

现在，我可以使用工具箱IP在端口8081上启动应用程序，它显示未定义的redis server: local:redis:6379:0

因为我正在使用工具箱，所以我假设我必须在撰写文件中放入一些正确的IP。

在$ docker run --name some-redis -d redis中单独使用redis

works和我可以在本地连接到服务器:6379

但是REDIS_HOSTS=local:redis:6379意味着什么呢？

有什么帮助来正确设置它吗？

我想你错过了链接你的两个容器。redis容器需要port + link，而redis命令需要正确的环境。您只能将容器名称用于链接/环境。

version: '3'
services:
  redis:
    container_name: redis
    hostname: redis
    image: redis
    ports
        - 6379:6379
    links: redis-commander

  redis-commander:
    container_name: redis-commander
    hostname: redis-commander
    image: rediscommander/redis-commander:latest
    build: .
    restart: always
    environment:
        - REDIS_HOSTS=redis
    ports:
        - 8081:8081

为了修复这个问题，你需要像这样连接redis和redis命令：

version: "3.9"

services:
  redis:
    image: redis:6.2.5
    command: redis-server --requirepass ${REDIS_PASSWORD}
    volumes:
      - redis:/var/lib/redis
      - redis-config:/usr/local/etc/redis/redis.conf
    ports:
      - ${REDIS_PORT}:6379
    networks:
      - redis-network

  redis-commander:
    image: rediscommander/redis-commander:latest
    restart: always
    environment:
      REDIS_HOSTS: redis
      REDIS_HOST: redis
      REDIS_PORT: redis:6379
      REDIS_PASSWORD: ${REDIS_PASSWORD}
      HTTP_USER: root
      HTTP_PASSWORD: root
    ports:
      - 8081:8081
    networks:
      - redis-network

volumes:
  redis:
  redis-config:

networks:
  redis-network:
    driver: bridge

或者说：

version: "3.9"

services:
  redis:
    image: redis:6.2.5
    command: redis-server --requirepass ${REDIS_PASSWORD}
    volumes:
      - redis:/var/lib/redis
      - redis-config:/usr/local/etc/redis/redis.conf
    ports:
      - ${REDIS_PORT}:6379
    links:
      - redis-commander

  redis-commander:
    image: rediscommander/redis-commander:latest
    restart: always
    environment:
      REDIS_HOSTS: redis
      REDIS_HOST: redis
      REDIS_PORT: redis:6379
      REDIS_PASSWORD: ${REDIS_PASSWORD}
      HTTP_USER: root
      HTTP_PASSWORD: root
    ports:
      - 8081:8081

volumes:
  redis:
  redis-config:
