apisix 灰度发布

文章目录

1、安装

安装教程：https://apisix.apache.org/zh/docs/apisix/installation-guide/

1.1、基于docker安装

# 下载
git clone https://github.com/apache/apisix-docker.git
cd apisix-docker/example

#启动
docker compose -p docker-apisix up -d

1.2、基于RPM安装

# 安装etcd
ETCD_VERSION='3.5.4'
wget https://github.com/etcd-io/etcd/releases/download/v${ETCD_VERSION}/etcd-v${ETCD_VERSION}-linux-amd64.tar.gz
tar -xvf etcd-v${ETCD_VERSION}-linux-amd64.tar.gz && \
  cd etcd-v${ETCD_VERSION}-linux-amd64 && \
  sudo cp -a etcd etcdctl /usr/bin/
nohup etcd >/tmp/etcd.log 2>&1 &

# 安装 OpenResty仓库
yum install -y https://repos.apiseven.com/packages/centos/apache-apisix-repo-1.0-1.noarch.rpm
# 安装 APISIX 的 RPM 仓库：
yum-config-manager --add-repo https://repos.apiseven.com/packages/centos/apache-apisix.repo
# 安装 APISIX
yum install apisix-2.13.1

#APISIX 安装完成后，你可以运行以下命令初始化 NGINX 配置文件和 etcd：
apisix init
#启动 APISIX
apisix start

2、灰度发布与蓝绿发布测试

三台虚拟机：

服务器	ip	应用
m1	192.168.28.133	apisix(网关)
s1	192.168.28.136	nginx(web服务)
s2	192.168.28.132	nginx(web服务)

s1、s2机器作为负载机器，完全灰度和蓝绿发布的测试机器。

2.1、compose安装nginx

s1和s2两台机器负责提供web服务，两台机器都通过docker安装nginx。安装配置如下。

2.1.1、创建目录

mkdir -p /home/nginx/www /home/nginx/logs /home/nginx/conf
vi /home/nginx/www/index.html

# index.html内容
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>docker测试</title>
</head>
<body>
    <h1>nginx正在运行</h1>

2.1.2、编辑nginx.conf配置文件

vi /home/nginx/conf/nginx.conf

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
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;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
    
    server{
       listen 80;
       server_name localhost;
       charset utf-8;

       location / {
          root   /usr/share/nginx/html/;
          try_files $uri $uri/ =404;
          index  index.html index.htm;
       }
       
       #error_page  404              /404.html;

       # redirect server error pages to the static page /50x.html
       #
       error_page   500 502 503 504  /50x.html;
       location = /50x.html {
           root   html;
       }
    }

vi /home/nginx/docker-compose.yml

version: '3.3'
services:
      nginx:
        image: nginx
        restart: always
        hostname: nginx
        container_name: nginx
        privileged: true
        ports:

2.3、traffic-split插件实现灰度和蓝绿发布

官方教程：https://apisix.apache.org/zh/docs/apisix/plugins/traffic-split/

2.3.1、灰度发布

通过weighted_upstreams的weight属性来实现流量分流。按 1:9 的权重流量比例进行划分，其中10%的流量到达运行在s1服务器，90%的流量到达运行在s2服务器。

3、jenkins与apisix整合，实现负载均衡和灰度发布

jenkins部署脚本参考https://blog.csdn.net/penngo/article/details/126687946


pipeline {
    // 省略的代码
    parameters {
        // 省略的代码
        choice(name: 'type', choices:[
            '灰度发布',
            '负载发布'
        ],description: '发布方式')
    }
    stages {
        // 省略的代码
    }
    post {
        success{
            script {
                def status_balance = 1
                def status_gray = 0
                if(params.type == "灰度发布"){
                    status_balance = 0
                    status_gray = 1
                }
                def route_balance = """curl http://127.0.0.1:9180/apisix/admin/routes/3 -H 'X-API-KEY: dds1c9f0343e5f13rf8dad84bb25c89d' -X PATCH -i -d '{"status": ${status_balance} }'"""
