Administration

Please note, the following commands can only be executed if you have direct access to the build cluster environment.

Create a new Jenkins instance

Run jenkins-new-instance.sh <project_id> '<project_display_name>'

e.g. for Eclipse CBI: jenkins-new-instance.sh technology.cbi 'Eclipse CBI'

Deploy a Jenkins instance

Run make deploy_<project_id>

e.g. for Eclipse CBI JIPP: make deploy_technology.cbi

Reload one or more Jenkins instance(s)

Run jenkins-reload.sh <project_id> [<project_id2>]

e.g. for Eclipse CBI JIPP: jenkins-reload.sh technology.cbi

Jenkins instance configuration options

Every Jenkins instance has it's own folder under instances/<project_id>, which contains a config.jsonnet file.

A minimal configuration in instances/technology.cbi/config.jsonnet would look like this:

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI"
  }
}

Executing make deploy_<project_id> in the Jiro root directory, creates all necessary files in the target folder utilizing templates from the templates/ directory.

Most configuration options are set by default and only need to be specified if they differ from the default.

Set a specific Jenkins version

By default the latest Jenkins version specified in https://github.com/eclipse-cbi/jiro-masters/masters.jsonnet is used. For testing purposes or in case of a regression, other versions can be specified.

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI",
  },
  jenkins+: {
    version: "2.263.3",
  }
}

Additional Jenkins plugins

List of plugins that are installed by default:
https://github.com/eclipse-cbi/jiro-masters/jiro.libsonnet

Additional plugins can be specified like this:

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI",
  },
  jenkins+: {
    plugins+: [
      "cloudbees-disk-usage-simple",
      "embeddable-build-status",
    ],
  },
}

Additional plugins for multiple JIPPs (e.g. all ee4j.* instances) can be specified in:
templates/plugins.libsonnet

Resource packs

Additional resource packs can be configured.

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI",
    resourcePacks: 3,
  },
}

Please note: by default, one resource pack is granted. If the project requests one additional resource packs, you need to specify the absolute number (2).

Adapt Jenkins controller resources according to the number of static agents

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI",
  },
  jenkins+: {
    staticAgentCount: 3,
  }
}

Set additional permissions

By default the LDAP group is determined by the fullName of the project. All members of the LDAP group get committer-level permissions, e.g. reading, configuring and starting jobs.

If the LDAP group differs from the fullName it can be set explicitly like this:

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI",
    unixGroupName: "eclipse.cbi"
  }
}

If people, who are not committers on the project, should get access to a Jenkins instance or committers should get additional permissions, they can be added individually:

local permissionsTemplates = import '../../templates/permissions.libsonnet';

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI",
  },
  jenkins+: {
    permissions+:
      permissionsTemplates.projectPermissions("webmaster@eclipse.org", ["Agent/Connect", "Agent/Disconnect"])
  }
}

Please note: requests for adding non-committers require a +1 from a project lead.

Set light theme

Jiro instances use a dark theme by default. If you are afraid of the dark, you can set a light theme.

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI",
  },
  jenkins+: {
    theme: "quicksilver-light",
  }
}

Set deployment options

Specific deployment options like host, prefix or cluster can be set.

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI",
  },
  deployment+: {
    host: "foundation.eclipse.org",
    prefix: "/ci/"+ $.project.shortName,
    cluster: "okd-c1",
  }
}

Set additional JCasC options

Specific JCasC options like static build agents, plugin configs, etc can be defined in instances/<project_name>/jenkins/configuration.yml.

E.g. instances/technology.cbi/jenkins/configuration.yml

jenkins:
  nodes:
  - permanent:
      labelString: "docker-build"
      launcher:
        ssh:
          credentialsId: "[...]"
          host: "13.77.107.72"
          jvmOptions: "-Xmx256m -Xms256m"
          sshHostKeyVerificationStrategy:
            manuallyProvidedKeyVerificationStrategy:
              key: "[...]"
      mode: EXCLUSIVE
      name: "fmlw3-ubuntu1804"
      nodeDescription: "4vCPU, 16GB RAM, Hosted @ Azure"
      remoteFS: "/home/genie.cbi/jenkins-agent"
      numExecutors: 2
      nodeProperties:
      - watcher:
          offlineAddresses: "releng@eclipse.org"
          onlineAddresses: "releng@eclipse.org"

unclassified:
  slackNotifier:
    teamDomain: "eclipsefoundation"
    tokenCredentialId: "[...]"

Build tools

Maven

Maven specific folders/configurations are created by default.

Gradle

Create Gradle specific folders/configurations (e.g. ~/.gradle)

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI",
  },
  gradle+: {
    generate: true,
  }
}

This will create a volume mount for /home/jenkins/.gradle/gradle.properties with the following content:

eclipseRepoPassword=<password>
eclipseRepoUsername=<username>

This is required for deploying artifacts to repo.eclipse.org.

sbt

Create sbt specific folders/configurations (e.g. ~/.sbt)

{
  project+: {
    fullName: "technology.cbi",
    displayName: "Eclipse CBI",
  },
  sbt+: {
    generate: true,
  }
}
