Enabling Octavia (Openstack) support in a cluster AFTER initial deployment? #349

Closed gerr1t closed 3 years ago

gerr1t commented 3 years ago

Describe the bug Currently, the support for OpenStack Octavia is set in the openshift-install configuration, with the option: octaviaSupport. That option is automatically set to 0 or 1, depending on whether that service is available in the OpenStack cluster. I have an OKD 4 cluster deployed on an OpenStack cluster without Octavia support. However, recently we deployed Octavia in the OpenStack cluster and therefore I would like to enable Octavia support in the existing cluster.

I have read the following documentation, however, it is related to a Kuryr deployment, which we are not using: https://docs.okd.io/latest/networking/load-balancing-openstack.html

Is it possible to enable support for Octavia AFTER the OKD cluster has been deployed without that support?

Version 4.5.0-0.okd-2020-09-04-180756

Hi @gerr1t , sorry for the delay, hopefully you have found your answer by now. It's possible to enable Octavia integration after the fact.

You'll need to edit your openstack cloud provider configuration:

oc edit cm cloud-provider-config -n openshift-config

And make sure that under data.config you have:

[LoadBalancer]
use-octavia = true

See the cloud provider documentation for available configuration options.

The use-octavia is currently not enabled by default, but will be in future versions of OKD.

We're using this trick in CI (to pass service distruption tests), so it works
