lua-resty-shell 是一个很不错的项目，让我们可以无阻塞的执行shell命令，之间的通信
是通过socket （一般是unix socket）
环境准备
version: "3"
services:
app:
build: ./
ports:
- "8080:80"
volumes:
- "./app/:/opt/app/"
- "./nginx.conf:/usr/local/openresty/nginx/conf/nginx.conf"
FROM openresty/openresty:alpine-fat
LABEL author="[email protected]"
WORKDIR /sockproc
COPY ./sockproc/ /sockproc/
RUN make sockproc
COPY entrypoint.sh /entrypoint.sh
COPY sockproc.sh /sockproc.sh
COPY shell.lua /usr/local/openresty/lualib/resty/shell.lua
ENTRYPOINT [ "/entrypoint.sh" ]
- dockerfile 说明
dockerfile 同时进行了socket 服务的构建以及shell lua 封装的copy，entrypoint 进行服务的启动
entrypoint.sh:
#!/bin/sh
sh /sockproc.sh
exec /usr/local/openresty/bin/openresty -g "daemon off;"
sockproc.sh:
#!/bin/sh
/sockproc/sockproc /tmp/shell.sock
openresty 集成测试
app/app.lua
local shell = require("resty.shell")
local args = {
socket = "unix:/tmp/shell.sock",
}
function call()
local status, out, err = shell.execute("cat /proc/sys/kernel/random/uuid", args)
ngx.say(out)
end
return call
- openresty content_by_Lua 阶段调用lua shell 封装
+ user root;
http {
+ lua_package_path '/opt/app/?.lua;;';
+ location /test {
+ content_by_lua_block {
+ require("app")()
+ }
