Openshift Pods Driver
|
|
---------------------
|
|
|
|
Selecting the openshift pods driver adds the following options to the
|
|
:attr:`providers` section of the configuration.
|
|
|
|
.. attr:: providers.[openshiftpods]
|
|
:type: list
|
|
|
|
The Openshift Pods driver is similar to the Openshift driver, but it
|
|
only supports pod label. This enables using an unprivileged service account
|
|
that doesn't require the self-provisioner role.
|
|
|
|
Example:
|
|
|
|
.. code-block:: yaml
|
|
|
|
providers:
|
|
- name: cluster
|
|
driver: openshiftpods
|
|
context: unprivileged-context-name
|
|
pools:
|
|
- name: main
|
|
labels:
|
|
- name: openshift-pod
|
|
image: docker.io/fedora:28
|
|
|
|
.. attr:: context
|
|
:required:
|
|
|
|
Name of the context configured in ``kube/config``.
|
|
|
|
Before using the driver, Nodepool services need a ``kube/config`` file
|
|
manually installed.
|
|
Make sure the context is present in ``oc config get-contexts`` command
|
|
output.
|
|
|
|
.. attr:: launch-retries
|
|
:default: 3
|
|
|
|
The number of times to retry launching a pod before considering
|
|
the job failed.

|
|
:type: list
|
|
|
|

|
|
corresponding label is available for use in this pool.
|

|

|
