API网关KONG的安装记录
学习用途，以容器的形式运行KONG，步骤如下：
创建网络： 所有模块都基于这个网络运行 docker network create kong-net
2依赖数据库版本： 如果不需要分布式，简单使用:postgres docker run -d --name kong-database –network=kong-net -p 5432:5432 -e “POSTGRES_USER=kong” -e “POSTGRES_DB=kong” -e “POSTGRES_PASSWORD=kongpass” postgres:9.6 (( 初始化数据库 docker run --rm --network=kong-net -e “KONG_DATABASE=postgres” -e “KONG_PG_HOST=kong-database” -e “KONG_PG_PASSWORD=kongpass” -e “KONG_PASSWORD=test” kong/kong-gateway:2.8.1.1-alpine kong migrations bootstrap ))
【3】启动KONG 注意不要携带企业版信息，否则启动有问题 docker run -d --name kong-gateway –network=kong-net -e “KONG_DATABASE=postgres” -e “KONG_PG_HOST=kong-database” -e “KONG_PG_USER=kong” -e “KONG_PG_PASSWORD=kongpass” -e “KONG_PROXY_ACCESS_LOG=/dev/stdout” -e “KONG_ADMIN_ACCESS_LOG=/dev/stdout” -e “KONG_PROXY_ERROR_LOG=/dev/stderr” -e “KONG_ADMIN_ERROR_LOG=/dev/stderr” -e “KONG_ADMIN_LISTEN=0.0.0.0:8001” -e “KONG_ADMIN_GUI_URL=http://localhost:8002” -p 8000:8000 -p 8443:8443 -p 8001:8001 -p 8444:8444 -p 8002:8002 -p 8445:8445 -p 8003:8003 -p 8004:8004 kong/kong-gateway:2.8.1.1-alpine
4试验验证： admin api curl -i -X GET --url http://localhost:8001/services
admin GUI api http://localhost:8002
【５】 增加服务入口验证 命令行如下： curl -i -X POST http://localhost:8001/services –data name=example_service –data url=‘http://mockbin.org’
curl -i http://localhost:8001/services/example_service
添加路由 curl -i -X POST http://localhost:8001/services/example_service/routes –data ‘paths[]=/mock’ –data name=mocking
测试路由: curl -i -X GET http://localhost:8000/mock/request

安装konga做图形管理========== docker run --rm –network=kong-net pantsel/konga -c prepare -a postgres -u postgresql://kong:kongpass@kong-database:5432/konga_db
docker run -d -p 1337:1337 –network=kong-nt -e “DB_ADAPTER=postgres” -e “DB_HOST=kong-database” -e “DB_USER=kong” -e “DB_PASSWORD=kongpass” -e “DB_DATABASE=konga_db” -e “KONGA_HOOK_TIMEOUT=120000” -e “NODE_ENV=production” –name konga pantsel/konga
