Examples of DevOps with Galaxy?

Hey. Looking for advice on the full CI/CD approach some of you all might be leveraging. Thinking:
Github/Bitbucket
Jenkins
Galaxy/mLabs

Any good articles on this?

How are you approaching environment deployment/mgmt for qa/staging/prod with Galaxy in your CI/CD? Are you just spinning up non-prod environments as needed and then taking down?

Any thoughts on nodechef vs galaxy yet?

Thanks. -W
