Hello Phil,
The "withCredentials" step exposes the credentials as Shell Environment
Variables, not as groovy variables.
You can find more details
on
https://support.cloudbees.com/hc/en-us/articles/203802500-Injecting-Secrets-into-Jenkins-Build-Jobs
Regarding Docker credentials, did you consider using the Pipeline Docker
Plugin and a "docker.withRegistry(...) {}" build wrapper? You can find a
sample here:
