How to run bash script from Nginx - bash

Question

1) I have static site and wand to set "autopull" from bitbucket.
2) I have webhook from bitbucket.
3) I have bash script which do "git pull"
How can I run this script when nginx catch request?
server {
listen 80;
server_name example.ru;
root /path/to/root;
index index.html;
access_log /path/to/logs/nginx-access.log;
error_log /path/to/logs/nginx-error.log;
location /autopull {
something to run autopull.sh;
}
location / {
auth_basic "Hello, login please";
auth_basic_user_file /path/to/htpasswd;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
}
}
I tried lua_block and fastcgi service, but both are failed.
lua does not run os.execute("/path/to/script") and does not write the log.
fastcgi is more successful, but it has not permissions, because my www-data user doesn't have ssh-key in my bitbuchet repo.

Answer 1

Problem solved.
I didnt want to use any script/process on another port because I have several sites and I need port for each.
My final configuration is:
server {
listen 80;
server_name example.ru;
root /path/to/project;
index index.html;
access_log /path/to/logs/nginx-access.log;
error_log /path/to/logs/nginx-error.log;
location /autopull {
content_by_lua_block {
io.popen("bash /path/to/autopull.sh")
}
}
location / {
auth_basic "Hello, login please";
auth_basic_user_file /path/to/htpasswd;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
}
}
Problem was in permission of www-data user and its ssh-kay in repo.

Based on this, create py script
#!/usr/bin/python
from BaseHTTPServer import BaseHTTPRequestHandler,HTTPServer
from subprocess import call
PORT_NUMBER = 8080
autopull = '/path/to/autopull.sh'
command = [autopull]
#This class will handles any incoming request from
#the browser
class myHandler(BaseHTTPRequestHandler):
#Handler for the GET requests
def do_GET(self):
self.send_response(200)
self.send_header('Content-type','text/html')
self.end_headers()
# Send the html message
self.wfile.write("runing {}".format(autopull))
call(command)
return
try:
#Create a web server and define the handler to manage the
#incoming request
server = HTTPServer(('', PORT_NUMBER), myHandler)
print 'Started httpserver on port ' , PORT_NUMBER
#Wait forever for incoming htto requests
server.serve_forever()
except KeyboardInterrupt:
print '^C received, shutting down the web server'
server.socket.close()
Run it and in nginx config add
location /autopull { proxy_pass http://localhost:8080; }
