Openshift - Automation Broker - Auto Discovery for charts in custom helm repository

12/17/2019

I have set up the automation broker using the below link and able to see the helm charts on service catalog from 'https://kubernetes-charts.storage.googleapis.com' repository.

https://blog.openshift.com/automation-broker-discovering-helm-charts/

My requirement is to set up a custom helm repository and I have done the same in Nexus.

enter image description here

I am able to add and search the charts from this repository on a kubernetes cluster where helm is installed. But now to automate this process and to see these charts on openshift service catalog, I have configured the nexus url in automation broker config. But I can not see the charts being available on service catalog for my nexus repository.

Can anybody help please?

Update: I also tried the same with openshift ansible service broker and I can see in the debug logs that two of these artifacts (mysql and redis) have been detected but they are not updated on service catalog.

Ansible Service Broker and automation broker is not working with nexus helm (hosted) repository because the index.yaml created in nexus repository is not having absolute url for a helm chart.

apiVersion: '1.0'
entries:
  my-app:
  - appVersion: 5.0.7

the url section should be the full path:

urls:
    - https://<ip>:<port>/nexus/repository/helm-release/my-app-0.1.0.tgz

But ansible service broker in openshift is looking for a absolute url in index.yaml which is being used in the service catalog of that app.

This looks to be a bug with service broker. There should be a fix to read the relative path because url is already given in the registry information of broker config.
