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 [email protected]"
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;
}
}
}

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
