1. 配置多个docker compose yml文件

docker-compose.yml
docker-compose-gray.yml

说明: 此处配置了两个, 配置多个yml文件的好处是可以单独发布某一个容器服务, 不影响其他的docker容器, 配合nginx的负载均衡即可达到不间断服务的目的。

docker-compose.yml 文件内容如下

version: '3.2'

services:
  wufu_webapi:
    build:
      context: ./
      dockerfile: ./manifest/docker/Dockerfile
    image: xxxx_webapi
    container_name: xxxx_webapi
    restart: unless-stopped
    environment:
      TZ: Asia/Shanghai
      LANG: en_US.UTF-8
    volumes:
      - "./manifest:/app/manifest"
      - "./public:/app/public"
      - "./temp:/app/temp"
    ports:
      - "8800:8800"

docker-compose-gray.yml 内容如下

version: '3.2'

services:
  wufu_webapi1:
    build:
      context: ./
      dockerfile: ./manifest/docker/Dockerfile
    image: wufu_webapi1
    container_name: wufu_webapi1
    restart: unless-stopped
    environment:
      TZ: Asia/Shanghai
      LANG: en_US.UTF-8
    volumes:
      - "./manifest:/app/manifest"
      - "./public:/app/public"
      - "./temp:/app/temp"
    ports:
      - "8801:8800"

2. nginx 配置负载均衡

upstream pancm{
  ip_hash;
  server 127.0.0.1:8800 max_fails=1 fail_timeout=60;
  server 127.0.0.1:8801 max_fails=1 fail_timeout=60;
}
server {
    # listen 80;
    listen 443 ssl;
    server_name xxxxx.com.cn;
    ssl_certificate  cert/xxxx/xxxxxx.com.cn.pem;
    ssl_certificate_key cert/xxxx/xxxxxx.com.cn.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    client_max_body_size 100m;


    
    location / {
      proxy_set_header        Host $http_host;
      proxy_set_header        X-Real-IP $remote_addr;
      proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header        X-Forwarded-Proto $scheme;
 
      # Fix the "It appears that your reverse proxy set up is broken" error.
      #proxy_pass          http://127.0.0.1:8800;
      proxy_pass          http://pancm;
      proxy_read_timeout  3000;
 
      proxy_redirect      http:// https://;
  
      # Required for new HTTP-based CLI
      proxy_http_version 1.1;
      proxy_request_buffering off;
    }
}

此nginx配置文件配置了两个轮循服务, 如果有一个服务访问失败就会重定向到另一个服务, 关于nginx的负载均衡还有其他方式,
如: 轮循(默认方式), weight 权重 , ip_hash,最少连接 等, 使用方式可自行百度。

3. 发布

首先安装alibaba cloud toolkit工具, 此处已goland举例, vscode也有这个工具。

alibaba cloud toolkit

配置发布路径及运行参数

alibaba cloud toolkit upload

在上传之后运行的命令

alibaba cloud toolkit select command

如下命令:

cd /data/web/wufu/wufu_webapi && docker compose up --build -d  && sleep 8s && docker compose -f docker-compose-gray.yml up --build -d && echo done!
