kong的安装以及简单配置

kong的安装以及简单配置_第1张图片

    1、下载镜像

2、安装

2.1、创建网络

2.2、安装postgres,kong依赖于postgres

2.3、初始化kong数据表信息

2.4、启动kong

2.5、初始化konga数据信息

2.6、启动konga

2.7、创建连接节点

2.8、创建Upstreams

2.9、配置services和routes

3.0、验证

3.1、其它


1、下载镜像

docker pull postgres:9.6-bullseye
docker pull kong/kong-gateway:2.4.1.0-alpine
docker pull pantsel/konga:0.14.9
  • 这3个镜像的版本必须匹配,否则初始化kong、konga数据时会出现各种问题。

2、安装

2.1、创建网络

docker network create yanshao_net

2.2、安装postgres,kong依赖于postgres

docker run -d --network=yanshao_net --name postgres \
    -p 5432:5432 \
    -e "POSTGRES_USER=kong" \
    -e "POSTGRES_DB=kong" \
    -e "POSTGRES_PASSWORD=kong" \
    postgres:9.6-bullseye

备注:

  • postgres默认端口5432,通过 -p 5432:5432,将5432暴露出来,当前主机可访问,否则只能在容器内访问。
  • -e "POSTGRES_USER=kong"、e "POSTGRES_DB=kong"、-e "POSTGRES_PASSWORD=kong"创建指定的库、用户名、密码
  • 启动成功之后,在数据库客户端检查postgres是否安装成功

 2.3、初始化kong数据表信息

docker run --rm --network=yanshao_net \
  -e "KONG_DATABASE=postgres" \
  -e "KONG_PG_HOST=postgres" \
  -e "KONG_PG_PASSWORD=kong" \
  -e "KONG_PASSWORD=kong" \
kong/kong-gateway:2.4.1.0-alpine kong migrations bootstrap
  •   -e "KONG_PG_HOST=postgres":是启动posgres数据库时,--name指定的名称
  •   -e "KONG_DATABASE=postgres": 指定当前kong使用的数据库类型,这里就是postgres
  •   -e "KONG_PG_PASSWORD=kong" : 数据库密码
  •   -e "KONG_PASSWORD=kong":数据库用户名

kong的安装以及简单配置_第3张图片

 2.4、启动kong

docker run -d --name kong-ee --network=yanshao_net \
  -e "KONG_DATABASE=postgres" \
  -e "KONG_PG_HOST=postgres" \
  -e "KONG_PG_PASSWORD=kong" \
  -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://127.0.0.1:9002" \
    -p 9000:8000 \
    -p 9443:8443 \
    -p 9001:8001 \
    -p 9444:8444 \
    -p 9002:8002 \
  kong/kong-gateway:2.4.1.0-alpine

kong有5个端口需要对外暴露

  • 8000:对应的http请求代理端口,后面配置代理时,需要用到它,这里对外暴露端口改成了9000
  • 8001:  http接口的管理端口
  • 8443:  对应的https请求的代理端口
  • 8444:  https接口的管理端口
  • 8002:  对api做了一些数据分析
  • kong启动之后,可以在浏览器输入:http://127.0.0.1:9002/overview,可以通过这个链接,检查kong是否安装成功

2.5、初始化konga数据信息

docker run --rm --network=yanshao_net  pantsel/konga:latest -c prepare -a postgres -u postgresql://kong:kong@postgres:5432/kong
debug: Preparing database...
Using postgres DB Adapter.

debug: User seed planted

  • 初始化成功之后,在postgres新增了11张表(现在是85张表,之前kong初始化时,创建了74张)

2.6、启动konga

docker run -d -p 1337:1337 --network yanshao_net --name konga \
 -e "DB_ADAPTER=postgres" \
 -e "DB_URI=postgresql://kong:kong@postgres:5432/kong" \
 -e "DB_PASSWORD=kong" \
 -e "NODE_ENV=production" \
 pantsel/konga:0.14.9
  • konga默认端口是1337,这里也需要对外暴露
  • 启动成功之后,输入http://127.0.0.1:1337/register,检查konga是否安装成功
  • 注册konga管理员账号

 2.7、创建连接节点

kong的安装以及简单配置_第6张图片

  • ip是当前主机ip地址,端口是9001(默认是8001,本文对外映射时设置成9001了)

2.8、创建Upstreams

  • 输入name,然后提交
  • 点击刚添加的upstream点击DETAILS添加targets,然后点击ADD TARGET输入target(ip+port)后点击SUBMIT TARGET即可,ip为本地电脑ip保证kong容器内可访问,端口为本地服务端口

  •  本地起一个简单的springboot服务,上面配置的ip + 端口,可直接访问这个springboot服务

kong的安装以及简单配置_第9张图片

 2.9、配置services和routes

kong的安装以及简单配置_第10张图片

  •  输入name、host(可以与前面Upstreams的name保持一致,也可以跟前面配置的ip保持一致)
  • protocol(协议类型,这里是http)
  • port这里是9000,kong启动之后,http的代理端口是8000,启动时做了对外映射,所以这里是9000
  • service保存后,点击service name进入详情页面,然后点击Routes添加路由规则
  • 点击ADD ROUTE输入name、paths(输入转发规则需按回车才生效),Strip Path(是否把匹配成功的paths删除后在转发后端服务器.),Preserve Host(转发后端是否带host参数,默认不带,Protocols 只保留http即可,最后点击SUBMIT ROUTE

3.0、验证

@RestController
@RequestMapping("/user")
public class UserController {

    @PostMapping("/v1/userInfo")
    public Map userInfo1(){
        Map res = new HashMap<>();
        res.put("version","v1");
        res.put("userName","Tiger");
        res.put("address","beijing");
        return res;
    }
}
  •  先在postman请求:http://127.0.0.1:8084/user/v1/userInfo
  • 然后请求:http://localhost:9000/cweb/user/v1/userInfo

 到这里,说明kong可以配置代理并且使用了!

3.1、其它

  • postgres的版本最好选择9.6.X(尝试过12.XX以上的版本都失败了,貌似konga最新的版本只能使用9.6.X以下的版本)
  • kong/kong-gateway最新版本需要当前主机安装openssl,而且需要安装openssl.rand等命令(尝试过,失败了)
  • pantsel/konga无法兼容12.0以上的版本(10.0和11.0没有试过),会有ssl验证的问题
