Nginx proxy and load-balancing settings management automation for marathon mesos environment.
This tool generates Nginx server configuration base on available Marathon tasks. It fetches all Marathon tasks via marathon REST api, then groups it by application. For each application it produces Nginx server definition file. This file, contains by default, reverse proxy and load balancing definition (you can customise this behaviour by providing your own config file template). Default server definition assumes that application will be launch using subdomain (ex. sample-app application will be called with http://sample-app.some-domain.com). It redirects to one of the hosts on which the application is deployed.
To install type in terminal
pip install marathon-proxy-manager
After installation you may launch it using following command:
python -m marathon_proxy_manager --marathon-url http://some-domain:8080 --domain some-domain --delete-unused --override --reload
You should run it with sufficient privileges to write to your Nginx configuration directory and to call service nginx reload
command (or you can provide --out-dir option and ).
To run this as a cron job add this line to the /etc/crontab:
* * * * * root python -m marathon_proxy_manager --marathon-url http://some-domain:8080 --domain some-domain --delete-unused --override --reload 2> /var/log/marathon_proxy_manager/err.log > /var/log/marathon_proxy_manager/out.log
