Summary

I'm planning to do a Talk on https://www.meetup.com/es/cloud-native-sevilla/ on 30th May with the title "Cloud Friendly Jenkins".

I would like to use https://ci.jenkins.io/ to present things like snippets configuration, agents builds, etc.

Reproduction steps

Hi @carlosrodlop , let's get started with a few (public) elements that can be used or referred to about the Jenkins infra and our usage of Jenkins with some "Cloud Native" systems:

• Ephemeral agents in Kubernetes clusters:
  • Controller running in Kubernetes and agents on the same cluster but different namespace (infra.ci.jenkins.io, private): https://github.com/jenkins-infra/kubernetes-management/blob/19f16d5fd67b866d43dad83b6b4929d6eca977e4/config/jenkins_infra.ci.jenkins.io.yaml#L122C15-L122C25
  • Controller running in a VM and agents in a Kubernetes cluster (ci.jenkins.io, public): https://github.com/jenkins-infra/jenkins-infra/blob/b7219b29e1cfe860d6ecad3929da43310cf21b99/hieradata/clients/controller.sponsorship.ci.jenkins.io.yaml#L115-L117 (and ERB template generating JCasc YAML: https://github.com/jenkins-infra/jenkins-infra/blob/b7219b29e1cfe860d6ecad3929da43310cf21b99/dist/profile/templates/jenkinscontroller/casc/clouds.yaml.erb#L233)
• Ephemeral agents running in Azure VMs (used for safe Docker):
  • Controller running in Kubernetes and agents in Azure VMs (infra.ci.jenkins.io, private): https://github.com/jenkins-infra/kubernetes-management/blob/19f16d5fd67b866d43dad83b6b4929d6eca977e4/config/jenkins_infra.ci.jenkins.io.yaml#L284
  • Controller running in a VM and agents in Azure VMs (ci.jenkins.io, public): https://github.com/jenkins-infra/jenkins-infra/blob/b7219b29e1cfe860d6ecad3929da43310cf21b99/hieradata/clients/controller.sponsorship.ci.jenkins.io.yaml#L345 (and ERB template generating JCasc YAML: https://github.com/jenkins-infra/jenkins-infra/blob/b7219b29e1cfe860d6ecad3929da43310cf21b99/dist/profile/templates/jenkinscontroller/casc/clouds.yaml.erb#L6)

Additionnaly, if you have a Jenkins LDAP account, you can log in on ci.jenkins.io and check the build output (expected to be public for contributors).

Default for plugins is to be built inside pod agents so you can check the Pod YAML in the build output:

Another "Cloud Native" tool we use is Docker Bake: it allows us to build multi platform Docker images for Jenkins (Controller and agents) at once (by platform we mean not only the usual Linux x86_64 and arm64, but also numerous Windows container images, Linux s390x CPU, etcs.)

• https://ci.jenkins.io/job/Packaging/job/docker-agent/job/master/ (public)

Thanks for the CNCF talk @carlosrodlop 👏
