尝试Docker Dev Environments

起因

nginx中大量相似的配置，仅仅前端项目的文件名，端口不同，因此考虑用shell生成
注意，因为我的nginx.conf文件不用改动，仅仅需要生成 default.conf文件，因此，以下文件为default.conf文件。
shell文件内容，根据自己需要进行增删

一、 生成结果展示

# financeapi server配置 由脚本生成
server {
    listen 1001;
    location  /financeapi/fsb/uploadFile/ {
        return 307 http://10.10.10.10/financeapi/fsb/uploadFile/;
    }
    location  /financeapi/ {
        if ($request_uri ~* "financeapi(/.*$)") {
            set  $path_remainder  $1;
        }
        proxy_pass http://$remote_addr:8079/$path_remainder;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_cookie_path / "/; HTTPOnly; SameSite=Lax; Max-Age=86400";
    }
    location / {
        root /home/docker/frontApp/finance-web/dist;
        index index.html;
        try_files $uri $uri/ /index.html;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_cookie_path / "/; HTTPOnly; SameSite=Lax; Max-Age=86400";
    }
    location = /auth/oauth2/authorize {
        rewrite ^  http://auth.lj.com/auth/oauth2/authorize;
    }
   
}

# financeapi server配置 生成成功


# csmapi server配置 由脚本生成
server {
    listen 1002;
   	...手动省略
}
# csmapi server配置 生成成功

... 其他省略

二、shell脚本

gen_nginx.sh 内容

#!/bin/bash
# 获取服务器配置
# source ./server-config.sh
source /etc/nginx/conf.d/server-config.sh

# nginx配置文件路径
# DEFAULT_CONF_PATH="./tmp_default.conf"
DEFAULT_CONF_PATH="/etc/nginx/conf.d/default.conf"

# 清空已存在的所有内容
echo '' > $DEFAULT_CONF_PATH 

# 开始生成 nginx配置
for index in "${!servers[@]}"
do
    server_element=${servers[$index]}
    IFS=':' read -r api_path back_app_port index_root <<< "$server_element"
    cat <<EOF >> $DEFAULT_CONF_PATH

# $api_path server配置 由脚本生成
server {
    listen $((START_PORT+index));
    location  /$api_path/fsb/uploadFile/ {
        return 307 $FILE_SERVER_URL/$api_path/fsb/uploadFile/;
    }
    location  /$api_path/ {
        if (\$request_uri ~* "$api_path(/.*\$)") {
            set  \$path_remainder  \$1;
        }
        proxy_pass $PROTOCOL\$remote_addr:$back_app_port/\$path_remainder;
        $PROXY_HEADER
    }
    location / {
        root /home/docker/frontApp$index_root;
        index index.html;
        try_files \$uri \$uri/ /index.html;
        $PROXY_HEADER
    }
    location = /auth/oauth2/authorize {
        rewrite ^  $PROTOCOL$AUTH_DOMAIN/auth/oauth2/authorize$is_args$args;
    }
   
}

# $api_path server配置 生成成功

EOF
done

配置文件内容，因为考虑尽量不依赖第3方工具，因此还是采用shell文件进行配置

#!/bin/bash

# 服务器配置数组
# 有新增的服务，修改以下配置
# ========================start========================================
#  序号=nginx开放端口:apiPath:indexRoot
servers=(
    # DT2.5项目  start
    "financeapi:8079:/finance-web/dist"
    "csmapi:8003:/csm-web/dist"
    "serverapi:8003:/mall-pc-web/dist"
    "saasapi:8081:/saas-web/dist"
    "tradeapi:8003:/trade-web/dist"
    # DT2.5项目  end
)

# ========================end========================================


# 其他参数配置
# 认证登录http前缀
AUTH_DOMAIN="auth.lj.com"

# 测试环境网关URL
FILE_SERVER_URL="http://10.10.10.10"

# 协议
PROTOCOL="http://"

# 公共header部分
PROXY_HEADER='proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_cookie_path / "/; HTTPOnly; SameSite=Lax; Max-Age=86400";'

# 起始端口
START_PORT=1001

三、 随Docker启动而执行

因为考虑到编排方便，用的是docker-conpose,
重点为“command” 那段配置，且 “nginx -g 'daemon off;” 作用为：

version: "3"
services:
  nginx:
    image: nginx:1.21.1
    container_name: os_nginx
    hostname: os_nginx
    privileged: true
    ports:
      - 8080:80
      - 1000-1099:1000-1099 #公共应用端口
    volumes:
      - ./deploy/nginx/sys/resolv.conf:/etc/resolv.conf
      - ./deploy/nginx/html/index.html:/home/docker/html/index.html
      - ./deploy/nginx/conf.d/:/etc/nginx/conf.d/
      - /app/dockerService/custService/frontend_updater/app/frontApp/:/home/docker/frontApp/
    command: sh -c "chmod +x /etc/nginx/conf.d/gen_nginx.sh && /etc/nginx/conf.d/gen_nginx.sh && nginx -g 'daemon off;'"
    networks:
      oversea_bridge:
        ipv4_address: 172.160.0.5
