type: script
scripts:
    - signing.sh 

Creating a script

Look at example.sh for an example shell script. You can rename and copy the file for your own purposes. In order for the script to be executed, declare it in the recipe

When creating a script, please make sure

• ...its filename ends with .sh.
  • This follows convention for (especially bash) shell scripts.
  • autorun.sh only executes files that match *.sh.
• ...it starts with a shebang like #!/usr/bin/env bash.
  • This ensures the script is ran with the correct interpreter / shell.
• ...it contains the command set -oue pipefail near the start.
  • This will make the image build fail if your script fails. If you do not care if your script works or not, you can omit this line.
