EC2 launch configuration user data is not executed

Question

I've just created a new Launch Configuration to use with an Auto Scaling group. When a new EC2 instance is launched, I would like the script to be executed.

In details:

I have a script deploy.sh that updates my application code using git...
When a new instance is launched by Auto Scaling, it should execute the script that I've provided via User Data in the Launch Configuration (attached on autoscaling group).

My user data is:

#!/bin/bash
/home/ec2-user/deploy.sh

This doesn't work.

Have you looked at your instance's system log? See here: docs.aws.amazon.com/AWSEC2/latest/UserGuide/… — spg

Can you check the permission of your deploy script?

You can login to the instance and check the logs of User Data execution. Logs are at /var/log/cloud-init-output.log

I've checked cloud-init-output.log and seems everything is okay.
I've done another test now and the new instance has the right code.
Probably there was a syntax error in launch configuration user data.

So, the right user data is

#!/bin/bash
/home/ec2-user/deploy.sh

Now I should add yum update before my custom script.
