How can I install unix package dependency for cloud composer?

[daniel...@umusic.com]

I'm using Cloud composer to run my airflow instance but not sure how to install packages for the airflow worker bash.

Previously I was running airflow on a google compute engine instance using docker, it was easy to specify requirements via the docker make file.

As someone who is new to kubernetes and Cloud composer, I was wondering if there is something similar I could do for kubernetes/Cloud composer as I previously did for docker?

I looking to install lzop for unix and also would need to update the gsutil boto config file with s3 credentials

How can I find .yml on kubernetes?

any help would be greatly appreciated
