kong的安装以及简单配置

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

80 executed

成功之后，可以在客户端看到创建了74张表

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.
Database exists. Continue...
debug: Hook:api_health_checks:process() called
debug: Hook:health_checks:process() called
debug: Hook:start-scheduled-snapshots:process() called

debug: Seeding User...
debug: User seed planted
debug: Seeding Kongnode...
debug: Kongnode seed planted
debug: Seeding Emailtransport...
debug: Emailtransport seed planted
debug: Database migrations completed!

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

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

2.9、配置services和routes

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<String,String> userInfo1(){Map<String,String> 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
