2.2、安装postgres，kong依赖于postgres
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_net2.2、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

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-alpinekong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/kongdebug: Preparing database...
Using postgres DB Adapter.
Database exists. Continue...
debug: Hook:api_health_checks:process() called

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;
}
}
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
