A short presentation about the concept of Elastic Jenkins.

1. Elastic JenkinsWhat is it and how can I do it?

2. Problem
Multiple masters each
with a pool of slaves
Random amounts of
usage per cluster and
time
Sharing slaves is really
hard

3. Solution
Abstract the underlying compute
Host multiple ephemeral slaves per actual VM
Allow n number of masters to utilize the cluster

4. Docker
Mesos
Kubernetes

5. Java needs to be in each one (just to run
the Jenkins slave process)
Ruby 1.9.3
SQLite
Postgres
Python
Ruby 2.0 Ruby 2.1
Ruby 2.2
Leiningen 1.x
Leiningen 2.x
ZeroMQ
JZMQ
Docker
Bashum

7. Mesos and k8s
The abstraction layer
Hosts both masters and slaves
Can be used in conjunction or separately

8. Let's make it better...

9. ...with CI as Code...

10. How?
Specific Docker images
(not the Build Pipeline Plugin)
External configuration system
Storing everything in git
Workflow...er Pipeline Plugin

11. There's still
something missing

12. Questions?
