GitHub Actions with ESP-IDF compilation

Question

I'd like to create a CI flow on GitHub Actions for a compilation process of my ESP-IDF-based project, over my self-hosted runner.

The ESP-IDF require exporting numerous shell variables and other shell-related tasks before the compilation. They provide a an export.sh script for that and expect the user (me) to source export.sh before the compilation steps.

How can I guarantee that all steps under a certain job are done under a custom shell with the ESP-IDF requirements?

I'm aware that I can have multi-line run commands in GitHub Actions, but that will require me to source export.sh on each step, won't it? This will slow down the job.

Thanks

You can use the docker image given by Espressif itself.
