CoreOS Stack and Instance Setup in AWS

NOTE: These instructions are not meant for production installs, but only for demos and proof-of-concept projects. A reboot or shutdown from the AWS interface will wipe the content of your instance.

Step 1:

Go to AWS Cloud Formation to create a new stack:

https://console.aws.amazon.com/cloudformation/home?region=us-east-1#/stacks/new

On that page you will upload the following template file.

This template file is an amended version of the "official" template from CoreOS. Primary changes:

• Default root volume size is set to 50GB.
• Firewall settings are fully open.
• Default instance type is set to m3.xlarge 
• Minimum cluster size is set to 1.
  
  

Step 2:

Fill in stack details as required.

Step 3:

You can leave these fields blank.

Step 4:

Review and click the Create button.

Step 5:

You will see the creation of the stack in progress. Click on the stack name to see the logged events, so as to catch any errors that may appear.

Step 6:

When the stack is created, click on the box in the top left corner.

Step 7:

Click on EC2.

Step 8:

Go to the Instances list.

Step 9:

You should now be able to find your new instance in the list.

Step 10:

Login with the appropriate PEM file selected in Step 2 and username core.
