lapis 是基于openresty 扩展的，所以直接将支持prometheus的模块构建进openresty 就可以了
我使用的是nginx-module-vts 模块
环境准备
我已经构建好了支持的基础镜像，可以直接配置即可，具体的可以看下面的参考资料
- docker-compose 文件
version: "3"
services:
api:
build: ./
ports:
- "8080:8080"
volumes:
- "./web:/web"- dockerfile
FROM dalongrong/lapis-1.7.0:metrics
ENTRYPOINT [ "lapis","server" ]- dalongrong/lapis-1.7.0:metrics 镜像
FROM dalongrong/openresty-nginx-module-vts:fat
RUN apk add openssl-dev
WORKDIR /web
RUN /usr/local/openresty/luajit/bin/luarocks install lapis- dalongrong/openresty-nginx-module-vts:fat 镜像
可以参考https://github.com/rongfengliang/openresty-nginx-module-vts - nginx.conf 配置vts 支持
主要是web 中nginx.conf 模版的添加
worker_processes ${{NUM_WORKERS}};
error_log stderr notice;
daemon off;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
vhost_traffic_status_zone;
server {
listen ${{PORT}};
lua_code_cache ${{CODE_CACHE}};
vhost_traffic_status_filter_by_set_key $uri uris::$server_name;
vhost_traffic_status_filter_by_host on;
location / {
vhost_traffic_status_bypass_limit on;
default_type text/html;
content_by_lua '
require("lapis").serve("app")
';
}
location /status {
vhost_traffic_status_display;
vhost_traffic_status_display_format html;
}
location /static/ {
alias static/;
}
location /favicon.ico {
alias static/favicon.ico;
}
}
}
启动&&测试
- 启动
docker-compose up -d- 效果
