Stop build EC2 AMI image if script fails

[Giorgio Cerruti]

Hi there,

I'm new to packer and I facing this issue. Basically, my workflow is to upload a bash script within the EC2 made by packer to install the stack I need to run my application. Now, sometimes something happens and the script fails to exit with an error code not equal 0, but packer still creating the AMI. How can I modify this behavior letting packer stops to build the AMI? I need this because of my CI/CD pipeline. Moreover, I added the `set -e` into my bash script.

Thanks in advance.

You say the script "fails to exit with an error code not equal to 0". So it is failing, and you have `set -e` but you aren't seeing Packer detect that it failed?

Try `set -euo pipefail` instead of just `set -e`.
