Diet Monkey

Shrink resources available on server.

• We run the script shrink.js which shrinks the allocated memory of the server if the utilization is less.
• It connects to the digital ocean droplets and reduced the memory.
• The scipt can be run as

node shrink.js

• Our droplet size was shrinked from a memory of 1gb to 512mb.

Restart Monkey

Restart server. Check if services properly restarted.

• We run the shell script restart.sh which initiates the server restart.

sh restart.sh

• It first calls the file reboot.js which reboots the server.

echo "Preparing to reboot server"
#call reboot script to reboot
node reboot.js

• Next, we induce a 30 second delay in the script so the server is back up fully.

echo "Getting services back up"
#30 seconds delay to allow for server to back up
sleep 30

• Further, it runs the restartplaybook.yml file using ansible to get the services back up.

#playbook to run the application back
ansible-playbook -i inventory restartplaybook.yml

• We can go the browser and run the application on port 3000 to see if it is back up.
