一.本地Docker部署及添加配置

1.docker 部署kong konga参考：https://www.cnblogs.com/jerryqm/p/12901036.html

1. 创建kong-net网络

docker network create kong-net

2. 启动PostgreSQL容器

docker run -d --name kong-database \
--network=kong-net \
-p 5432:5432 \
-e "POSTGRES_USER=kong" \
-e "POSTGRES_DB=kong" \
-e "POSTGRES_PASSWORD=kong" \
postgres:11.7

3. 运行临时Kong容器迁移数据库

docker run --rm \
--network=kong-net \
-e "KONG_DATABASE=postgres" \
-e "KONG_PG_HOST=kong-database" \
-e "KONG_PG_PASSWORD=kong" \
-e "KONG_CASSANDRA_CONTACT_POINTS=kong-database" \
kong:latest kong migrations bootstrap

4. 启动Kong容器

docker run -d --name kong \
--network=kong-net \
-e "KONG_DATABASE=postgres" \
-e "KONG_PG_HOST=kong-database" \
-e "KONG_PG_PASSWORD=kong" \
-e "KONG_CASSANDRA_CONTACT_POINTS=kong-database" \
-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, 0.0.0.0:8444 ssl" \
-p 80:8000 \
-p 443:8443 \
-p 8001:8001 \
-p 8444:8444 \
kong:latest

测试kong

curl -i http://localhost:8001/

konga dashboard

# 迁移konga数据表到pgsql
docker run --name konga --rm \
--network=kong-net \
pantsel/konga -c prepare -a postgres -u postgresql://kong:kong@kong-database:5432/kong

# 启动konga
docker run -p 1337:1337 -d \
--network=kong-net \
-e "DB_ADAPTER=postgres" \
-e "DB_HOST=kong-database" \
-e "DB_USER=kong" \
-e "DB_PASSWORD=kong" \
-e "DB_DATABASE=kong" \
-e "KONGA_HOOK_TIMEOUT=120000" \
-e "DB_PG_SCHEMA=public" \
-e "NODE_ENV=production" \
--name konga \
pantsel/konga

2.添加插件可以在 /usr/local/share/lua/5.1/kong/plugins下 挂载插件的文件夹，配置参考：https://blog.csdn.net/weixin_40027906/article/details/86679366，修改的运行kong命令如下

docker run -d --name kong \
     --network=kong-net \
     -e "KONG_DATABASE=postgres" \
     -e "KONG_PG_HOST=kong-database" \
     -e "KONG_PG_PASSWORD=kong" \
     -e "KONG_CASSANDRA_CONTACT_POINTS=kong-database" \
     -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, 0.0.0.0:8444 ssl" \
     -p 8000:8000 \
     -p 8443:8443 \
     -p 127.0.0.1:8001:8001 \
     -p 127.0.0.1:8444:8444 \
     # 挂载插件
     -v /Users//k8s/kong/kong/plugins/ipFilter/schema.lua:/usr/local/share/lua/5.1/kong/plugins/ipFilter/schema.lua \
     -v /Users//k8s/kong/kong/plugins/ipFilter/handler.lua:/usr/local/share/lua/5.1/kong/plugins/ipFilter/handler.lua \
     # 注册插件
     -v /Users/k8s/kong/kong/plugins/constants.lua:/usr/local/share/lua/5.1/kong/constants.lua \
     kong:latest

常用的命令

进入容器 docker exec -it --user root ce2b9f93f3c5 /bin/bash
插件目录：/usr/local/share/lua/5.1/kong/plugins/
kong admin url: http://kong:8001

可以看见，ipFilter插件挂载成功

3.设置service router的参考这篇 : 传送门

4. 使用redis 设置黑名单

在kong插件中使用redis

查看容器log

docker log -f 容器id

172.22.0.1 - - [03/Dec/2020:06:07:03 +0000] "GET /hao123 HTTP/1.1" 200 76914 "-" "PostmanRuntime/7.26.8"
2020/12/03 06:07:33 [error] 24#0: *72799 [kong] handler.lua:32 [ipFilter] IP 172.22.0.1  access denied, client: 172.22.0.1, server: kong, request: "GET /hao123 HTTP/1.1", host: "127.0.0.1:8000"
172.22.0.1 - - [03/Dec/2020:06:07:33 +0000] "GET /hao123 HTTP/1.1" 403 30 "-" "PostmanRuntime/7.26.8"

二.k8s集群部署

k8s配置管理

kubectl create configmap kong-plugin-auth --from-file=auth -n dev

auth是当前目录下的的文件夹，里面是自定义插件的lua script

plugins: 
  configMaps:
  - name: kong-plugin-auth
    pluginName: auth

遇见的错误

1.k8s 集群内 Redis: ERR illegal address

Redis-正确设置Redis的的白名单，应该在白名单中添加 ECS的私有IP及密码（k8s节点ip） 如果想使用公共IP，则需要两个都换成公有地址
