kong和konga的安装教程

kong是一个网关服务，konga是一个连接kong的免费开源的管理工具客户端，Kong自带的管理工具需要付费。

1、安装docker-compose，通过docker客户端启用docker-compose

2、编辑compose.yml文件

version: '3'
services: 
  kong-database:
    image: postgres:9.6
    restart: always  #每次总是启动
    networks: 
      - kong-net
    environment:
      POSTGRES_USER: kong
      POSTGRES_DB: kong
      POSTGRES_PASSWORD: kong
    ports:
      - "5432:5432"

  kong-migration:
    image: kong:latest
    command: "kong migrations bootstrap"
    networks: 
      - kong-net
    restart: on-failure
    environment:
      - KONG_DATABASE=postgres
      - KONG_PG_DATABASE=kong
      - KONG_PG_PASSWORD=kong
      - KONG_PG_HOST=kong-database
    links: 
      - kong-database #连接的是kong-database服务的
    depends_on:
      - kong-database #依赖于kong-database服务

    networks:
      - kong-net
    environment:
      KONG_DATABASE: postgres
      KONG_PG_HOST: kong-database
      KONG_PG_PASSWORD: kong
      KONG_PROXY_LISTEN: 0.0.0.0:8000
      KONG_PROXY_LISTEN_SSL: 0.0.0.0:8443
      KONG_ADMIN_LISTEN: 0.0.0.0:8001
    depends_on:
      - kong-migration
    links: 
      - kong-database
    healthcheck:
      test: ["CMD", "curl", "-f", "http://kong:8001"]
      interval: 5s
      timeout: 2s
      retries: 15
    ports:
      - "8001:8001"
      - "8000:8000"
      - "8443:8443"

#以下两个是konga  GUI
#######################
  konga-prepare:
    image: pantsel/konga:latest
    command: "-c prepare -a postgres -u postgresql://kong:kong@kong-database:5432/konga"  #注意是用户名：密码@数据库服务名称：端口
    networks:
      - kong-net
    restart: on-failure
    links:
      - kong-database
    depends_on:
      - kong        #依赖kong服务
      - kong-database #依赖kong-database服务

  konga:
    image: pantsel/konga:latest
    restart: always
    networks:
      - kong-net
    environment:
      DB_ADAPTER: postgres
      DB_HOST: kong-database
      DB_USER: kong
      DB_DATABASE: konga
      DB_PASSWORD: kong #必须加上密码，不然会失败
    depends_on:
      - kong
      - kong-database
    ports:
      - "1337:1337"
networks:
  kong-net:
    driver: bridge

3、在yml文件目录先执行命令

docker-compose up -d

4、添加kong，特别注意需要添加为ip:8001，localhost跟127.0.0.1都无法添加成功
