 ## Jenkins X
 [**Jenkins X**](https://jenkins-x.io) is a specialized Jenkins for Kubernetes: This is how it works from a bird eye the CI/CD:  a developer creates a branch, then Jenkins X creates a ephemeral namespace with that branch. The developer tests it and once it is ok, a PR is created, then, the branch is deployed in staging.  When I merge it, it goes to QA, and with a manual command "jx promote" it goes to production.  Jenkins X deletes automatically after N hours the branch namespace.
