keeps getting roll_back

I don't know if any has try this but I kept getting roll_back failures. Also the roll_back eventually failed due to dependencies.

You may want to check out issue #1 to see if your stack is also failing to start because it cannot find the CloudWatch Logs log group.

Note that to see the cfn-init log you would need to set the "Rollback on Failure" option to "No" while setting up the CloudFormation stack.

Then you would be able to ssh to any one of your EC2 instances using the key pair you chose when setting up the CloudFormation stack:

chmod 400 <your-key>.pem
ssh -i "<your-key>.pem" ec2-user@<ec2-public-ip>

From the EC2 instance you may want to check the following log files for any errors:

• /var/log/cfn-init-cmd.log
• /var/log/cloud-init.log
