AutoScaling

Note: To remove the infrastructure that you have created, just re-run the script and it will prompt you for destroying the infra that you created. Infra that already exists(not created by the script) cannot be destroyed by the script.

1. Clone the VPC branch of the AutoScaling repo in micky.

git clone -b vpc https://mgtsys:[email protected]/mgtsys/AutoScaling.git ~/AutoScaling/vpc

2. Now execute the vpc.sh script to create the VPC.

cd /home/mgt/AutoScaling/vpc && bash vpc.sh

3. You will be asked to enter the following details.

   • Enter your AWS ACCESS KEY:

   • VPC

6. Now, launch the instance from MGT Backend in the newly created VPC and proceed with setting up Admin and WebMaster servers.

IMPORTANT: Make sure your instances are named in the following format Admin = "$projectname-admin" WebMaster = "$projectname-web-master"

It is important for the script to detect the names in mentioned format to fetch the properties.

7. Once the servers are up and running, you can proceed with the cloning the ASG branch of the AutoScaling repo in micky.

git clone -b asg https://mgtsys:[email protected]/mgtsys/AutoScaling.git ~/AutoScaling/asg
