A Continuous Journey with Jenkins

Transcript

1. A Continuous Journey with Jenkins
2. Meet Me David B. Schott Sr. Biz Dev Eng / Partner SA CloudBees, Inc. 2 dbschott schottsfired
3. Meet Jenkins -An open source automation server -Facilitates Continuous Integration (CI) and Continuous Delivery (CD) -Flexible and extensible with 1550+ Plugins 3
4. Our Journey Begins...
5. Huge success!
6. Weeks later...
7. Attach Agents! Master Agent Execute commands Logs, test results, artifacts
8. - Agents become snowflakes - Competition for resources Weeks later...
9. CloudBees DevOptics - Run Insights - Free* Forever! https://www.cloudbees.com/products/cloudbees-devoptics 9 *
10. Now what? Developers: must we point and click to make things work in Jenkins? 10
11. CI/CD instructions as code Durable Resumable Auditable Reviewable Programmatic Shareable Convert to Pipeline! //Jenkinsfile.groovy pipeline { agent { docker 'maven:3-alpine' } stages { stage('Example Build') { steps { sh 'mvn -B clean verify' } } } }
12. CloudBees Blue Ocean 12
13. A DevSecOps Blue Ocean Pipeline.. “It’s at this point in our journey that we can implement DevSecOps, like so” 13
14. - Increased adoption - More builds, more branches - Additional master load Weeks Later...
15. - No more load issues - Failures are less impactful - Teams have their own - Plugins - Configurations - Build queue Scale Masters!
16. - Optimizing agent resources - Difficulties - Managing - Securing - Governing - Operationalizing Scaling Challenges
17. CloudBees Core https://www.cloudbees.com/products/cloudbees-core 17 Jenkins Operations Center Jenkins Master Project Team 1 Jenkins Master Project Team 2 Jenkins Master Project Team 3 Jenkins Master Project Team 4 Build Agent Build Agent Build Agent Build Agent Build Agent Build Agent RBAC LDAP Plugin Catalog Shared Agents
18. Now what? Kubernetes (K8s), oh my! 18
19. - Fault tolerant by default - Small and nimble - Fewer moving pieces during upgrades - Bin packing Masters in Kubernetes
20. - Launched on demand, as capacity allows - May be defined by end users - Simplified tooling and dependency management - Steps are run in containers - Shared workspace Agents in Kubernetes //Jenkinsfile.groovy pipeline { agent { kubernetes { //cloud 'kubernetes' label 'mypod' yaml """ apiVersion: v1 kind: Pod spec: containers: - name: maven image: maven:3.3.9-jdk-8-alpine command: ['cat'] tty: true """ } } stages { stage('Run Maven') { steps { container('maven') { sh 'mvn -version' } } } } }
21. - How do we treat masters as cattle, not pets? - How do we leverage Cloud services? - How do we onboard new apps more quickly? - What does K8s-native CD look like? Cloud Native Thinking
22. Webhook “The world is envisioned as a repo and not as a kubernetes installation" - Kelsey Hightower GitOps Pattern 22 Desired State Operator Apply
23. Towards a Cloud Native Jenkins 23 Building blocks Pluggable Storage Configuration as Code Jenkins X
24. Configuration as Code https://jenkins.io/projects/jcasc/ 24
25. - Goal: eliminate the need for jenkins_home - How? - Artifact Manager for S3 - Kubernetes Credentials Provider - Logs → Elasticsearch, Fluentd, CloudWatch - Many more, WiP Pluggable Storage /jenkins_home /jobs /plugins ... https://jenkins.io/sigs/cloud-native/pluggable-storage/
