Today’s infrastructure

5

• 220+ Jenkins instances

• Beefy machines(total ~250 cores, ~1.5TB RAM)

• A few dedicated slaves(e.g. for Windows and Mac)

Today’s infrastructure

6

• Managing 10s of Jenkins is “easy”, managing 100s of them is time consuming

• We want to spend our time on areas that add value: • Harden digital signature and packaging services• Ease publication/promotion (Maven central, Nexus, ...)• Better support of static analysis tools (SonarQube, …)• Better integration with GitHub

Today’s infrastructure

7

• We also want to offer better performance• Pool our hardware to use it more efficiently• QoS - better isolation and control over resources usage• Be able to add additional resources more easily

• Either cloud-based or on-premise

Next generation status quo

14

Already running on new infra:• Every new provisioned JIPP

• Early adaptors like Xtext

• ~40 Jakarta EE projects

CBC and cluster problems

15

• We had some stability issues in the beginning

• Responsive and excellent support by CloudBees

• Cluster is now much more stable

Migrating OSS Jenkins instances to CBC

16

• How?• No built-in solution for mass migration of jobs• => Custom solution

• What needs to be moved?• Job configurations• Views• Credentials• Maven settings

FAQ

20

• Why does my build take so long and how can I make it faster?

• What are Jenkins pipelines and why/when should they be used?

Copyright (c) 2018, Eclipse Foundation, Inc. | Made available under the Eclipse Public License 2.0 (EPL-2.0)

Jenkins Pipelines

21

• Store your job config in your repo

• Config linked to code

• Config history

• Scripted Pipeline vs Declarative Pipeline

• Recommended for docker based builds

Best practices

24

• Modular builds and tests => Parallelization

• Play fair and don’t be a resource hog

• Build configuration in Code => Pipelines

• Docker
