$ oc edit template jenkins-ephemeral -n openshift
The first time a user creates a build configuration using the
Pipeline
build strategy, OpenShift Origin looks for a template named
jenkins-ephemeral in the openshift namespace and instantiates it within
the user’s project. The jenkins-ephemeral template that ships with
OpenShift Origin creates, upon instantiation:
a deployment configuration for Jenkins using the official OpenShift Origin Jenkins image
a service and route for accessing the Jenkins deployment
a new Jenkins service account
rolebindings to grant the service account edit access to the project
Cluster administrators can control what is created by either modifying the content of the built-in template, or by editing the cluster configuration to direct the cluster to a different template location.
To modify the content of the default template:
$ oc edit template jenkins-ephemeral -n openshift
To use a different template, such as the jenkins-persistent template which uses persistent
storage for Jenkins, add the following to your master configuration file:
jenkinsPipelineConfig:
autoProvisionEnabled: true (1)
templateNamespace: openshift (2)
templateName: jenkins-pipeline (3)
serviceName: jenkins-pipeline-svc (4)
parameters: (5)
key1: value1
key2: value2| 1 | Defaults to true if unspecified.
If false, then no template will be instantiated. |
| 2 | Namespace containing the template to be instantiated. |
| 3 | Name of the template to be instantiated. |
| 4 | Name of the service to be created by the template upon instantiation. |
| 5 | Optional values to pass to the template during instantiation. |
When a Pipeline build configuration is created, OpenShift Origin looks for a
Service matching serviceName. This means serviceName must be chosen
such that it is unique in the project. If no Service is found, OpenShift Origin
instantiates the jenkinsPipelineConfig template. If this is not desirable
(if you would like to use a Jenkins server external to OpenShift Origin, for
example), there are a few things you can do, depending on who you are.
If you are a cluster administrator, simply set autoProvisionEnabled to false.
This will disable autoprovisioning across the cluster.
If you are an unpriviledged user, a Service must be created for OpenShift Origin
to use. The service name must match the cluster configuration value of
serviceName in the jenkinsPipelineConfig. The default value is
jenkins. If you are disabling autoprovisioning because you are running a
Jenkins server outside your project, it is recommended that you point this new
service to your existing Jenkins server. See:
Integrating External Services
The latter option could also be used to disable autoprovisioning in select projects only.
