Introduction
I have an automation script, that I want to run on different environments, with a cron schedule. I’m using a web-service, and the endpoints are different for each environment.
Also, I would need credentials for calling that web-service apis.

not { changeset pattern: ".*", comparator: "REGEXP" }

}Description
I’m doing following in above file:
- Schedule job every 24 hours:
cron('0 0 * * *') - Not to run on code commit
- Taking credentials from Jenkins using
UsernamePasswordMultiBinding, and exposing in environment variables - Installing python requirements
- Run automation via shell script
- Then running automation run step in parallel, for each environment (dev/stage/prod)
- Setting web service URL in environment variable
