kubernets中jenkins使用清华源加速插件安装

加速思路

清华源jenkins插件地址

https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

查看json中依然有很多源指向

updates.jenkins-ci.org

思路，在jenkins所在pod中添加一个sidecar，将 updates.jenkins-ci.org 重定向到 mirrors.tuna.tsinghua.edu.cn，不对原有jenkins镜像侵入，方便以后升级

构建proxy-tuna镜像

docker build -t dolphintwo/jenkins-plugins-proxy:v0.1 .

Dockerfile

FROM nginx:1.17.6-alpine
LABEL maintainer="dolphintwo dtdinghui2@gmail.com"

COPY nginx.conf /etc/nginx/nginx.conf

nginx.conf

user  nginx;
worker_processes  auto;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
    log_format  main  ‘$remote_addr - $remote_user [$time_local] "$request" ‘
                      ‘$status $body_bytes_sent "$http_referer" ‘
                      ‘"$http_user_agent" "$http_x_forwarded_for"‘;

    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;

        location /download/plugins {
            proxy_next_upstream http_502 http_504 error timeout invalid_header;
            proxy_set_header Host mirrors.tuna.tsinghua.edu.cn;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
            rewrite /download/plugins(.*) /jenkins/plugins/$1 break;
            proxy_pass https://mirrors.tuna.tsinghua.edu.cn;
        }
    }
}

      volumes:

          persistentVolumeClaim:

　　注意添加sidecar并指定host拦截请求

　　deployment只是本次实验中的示范，应该也可以创建有状态应用中使用

验证

在插件中心更新插件，查询pod中两个容器日志
