Bitbucket runner configuration to call a kas build process

[andreas_jung]

Hello,

I need a hint how to handle variables in a self hosted runner on Linux, using KAS for setting up a Yocto project.

In my bitbucket-pipeline.yml file I have defined as follows:

definitions:
steps:
- step: &build
name: KAS Build
runs-on: [self.hosted, linux.shell]
script:
- kas checkout build.yml
- source generate_key.sh
- kas build --skip repos_checkout build.yml

The kas build.yml file contains:

env:

   KEY_HEX: none

My issue: the script generate_key.sh assigns a key to the variable KEY_HEX .
The kas build call should then forward the variable to the bitbake environment via BB_ENV_PASSTHROUGH_ADDITIONS.

But the variable content is not forwarded to bitbake.

My question is: how to export a variable from the script generate_key.sh  to kas?

I guess all three calls within the script generate child processes that do not know variables from other.

Thank you very much for any advice!

Regards

Andreas
