4. Continuous Integration

5. Jenkins – A quick view as a CI tool.
A Scheduler
Unit of execution is job (project or build or test).
 Jobs can be orchestrated as a workflow to run one after the other.
Global configuration : Common across all jobs.
Job configuration : Specifics to the job.
Highly pluggable. A lot of plugins available
 Job trigger
 Slave choice [usual VM, Docker, Mesos etc]
 For handling artifacts
 Views, Intimation and Reports
 Specific plugins for important QA/build tools (Maven, Gradle, TestNG, Selenium etc).

6. Mesos
 Resource Allocation - Acts as a broker – Manages the robustness around this.

7. Docker
IaaC
Docker images => Docker containers
Predictable environment (when compared to VMs and other
slave boxes)
Quick
Easy lifecycle
Isolated.

8. The Marriage
Mesos Jenkins
Plugin

9. DEMO
Go over the configuration
Trigger a job on Jenkins
See the resource getting allocated
See the docker container getting created
Job executing.

10. Benefits
Mesos-Docker based cloud compute resource pool. IaaS in the
form of containers.
Containers => Mesos & Docker containers
Predictable and determinate Infrastructure.
High Availability using zookeeper and production level systems.
Scalable to 10,000 of nodes.
Heterogeneous cloud setup.
Multitentant
Nodes can be VMs/ Bare metal.
Centralized maintenance & Elastic.

11. Compatibility
Mesos 1.10 + Docker 1.13.1 + Mesos-Jenkins plugin
0.14
