Introduction to Jenkins X

If you've been to tech conferences, you probably have noticed that most talks are for advanced users. This is especially the case when talking about #kubernetes.

We need to focus on folks that have not heard or ever touched modern frameworks or technologies. Not everyone knows or is an expert with Helm, Draft, Chartmuseum, Prow, Lighthouse, Docker, Kubernetes, and many other open-source tools.

Yes, these people exist and many times are ignored as an audience at large conferences.

This week at DevOps World | Jenkins World in Lisbon, I wanted to introduce folks to Jenkins X in the simplest way. It was amazing to see just how many people attended and asked questions. Thank you to all of those who attended!

20. © 2019 All Rights Reserved. 20 Jenkins X Capabilities Pipelines in Jenkins X • Pipelines are declarative (YAML) • Each stage runs on its own ephemeral pod • PR vs. Release Pipelines • Dozens of pre-configured builder images
21. © 2019 All Rights Reserved. 21 Jenkins X Capabilities Triggering Pipelines • Prow / Lighthouse • Via ChatOps PR comment “/test this” or “/approve” • GitHub Statuses Triggered via different events
22. © 2019 All Rights Reserved. 22 Jenkins X Capabilities Monitor Pipelines Several methods to monitor Pipeline activity # get build logs for a pipeline >$ jx get build logs # get pipeline activity for an app >$ jx get activity -f appname The Jenkins X UI
23. © 2019 All Rights Reserved. 23 Jenkins X Capabilities Monitor Pipelines Install the UI # Install the UI >$ jx add app jx-app-ui --version=0.1.26 # Launch UI in browser >$ jx ui -p 9845
