k8s operation and maintenance in mind - how to make kong gateway deployed to k8s managed custom static resources?

purpose

Use kong directory as /data/reportsstatic resource server, in order to test directory was /data/reportscreated under the file report.html, as follows:

<html>
<head></head> <body><h1>测试报告</h1></body> </html>

First, write a custom template nginx

Get kong custom configuration nginx

[root@justmine ~]# kubectl -n [kong所在的命名空间] exec -it [kong pod完全限定名] sh 
[root@justmine ~]# cat /usr/local/kong/nginx.conf

The nginx.conf copied out the content, the new nginxtemplate will be modified in this content, avoiding the revised unable to start kong container.

Add hosting static resource allocation

worker_processes auto;
daemon off;

pid pids/nginx.pid;
error_log /dev/stderr notice;

worker_rlimit_nofile 65536;

events {
    worker_connections 16384;
    multi_accept on;
}

http {
    include 'nginx-kong.conf';
    # 上面为kong本身配置，下面为提供静态资源的配置。
    server {
        listen 8005 default_server;
        index index.html;
        root /kong/nginx/www;
    }
}

Save the file above to k8s

[root@justmine ~]# kubectl -n [kong所在的命名空间] create configmap kong-nginx-custom-config --from-file=/data/kong/custom_nginx.template

Second, the configuration kong

Mount Custom Configuration

volumes:
- configMap:
          defaultMode: 420
 name: kong-nginx-custom-config  name: kong-nginx-custom-config ---中间省略--- - mountPath: /usr/local/kong/nginx.conf  name: kong-nginx-custom-config  subPath: custom_nginx.template

Mount static resource directory

- mountPath: /kong/nginx/www
          name: staging-test-reports
---中间省略--- - hostPath:  path: /data/reports  type: DirectoryOrCreate  name: staging-test-reports

Add services and routing

#!/bin/bash

set -e
IFS=$'\n\n'

echo ""
echo "Start building the cnd-sure-route dynamically..."

declare svcName="自定义服务名称"
declare kongServiceBaseUrl="http://[kong admin地址]/services"
declare sureRouteSvcUrl="http://localhost:8005"

# resilience handle
# Maximum time in seconds that you allow the whole operation to take. declare maxTime=5 # Maximum time in seconds that you allow the connection to the server to take. declare maxConnectTime=2 declare retryCount=5  ## add services function createService() { curl -X POST $1 \ --connect-timeout $2 \ --max-time $3 \ --retry $4 \ -H "accept: application/json" \ -H "Content-Type: application/json" \ -d "{ \"name\": \"$5\", \"url\": \"$6\"}"; } createService $kongServiceBaseUrl $maxConnectTime $maxTime $retryCount $svcName $sureRouteSvcUrl  ## add routes declare kongRouteBaseUrl="http://[kong admin地址]/routes" declare kongRouteDomain="[路由绑定的域名]" function createRoute() { declare svcResponse=$(curl -X GET $kongServiceBaseUrl/$5 --connect-timeout $2 --max-time $3 --retry $4) declare JQ_EXEC=`which jq` declare svcId=$(echo $svcResponse | ${JQ_EXEC} .id | sed 's/\"//g') declare defMethods="[\"GET\"]" set +e if [ -n "$8" ]; then defMethods=$8 fi if [ -z "$svcId" ]; then echo "Warnning, failed to get the service[$5] identifier, route cannot be created."; else curl -X POST $1 \ --connect-timeout $2 \ --max-time $3 \ --retry $4 \ -H "accept: application/json" \ -H "Content-Type: application/json" \ -d "{ \"service\": "{\"id\":\"$svcId\"}",\"paths\": "[\"$6\"]",\"methods\": "$defMethods",\"strip_path\":$7,\"hosts\": "[\"$kongRouteDomain\"]"}"; fi set -e } declare sureRouteRouteUrl="/" createRoute $kongRouteBaseUrl $maxConnectTime $maxTime $retryCount $svcName $sureRouteRouteUrl true echo "" echo "Dynamicly building the cnd-sure-route successfully !!!"

Note: You can also use kong dashboad completion of the above shell script.

Third, the test

Do a background of software workers
