Customizing prometheus configuration fails with MountVolume issue

[abouchama]

When we enable the trait --trait prometheus.configmap=prometheus-vol fails with the following error:

Unable to attach or mount volumes: unmounted volumes=[i-resource-000], unattached volumes=[i-resource-000 prometheus-vol default-token-jpfxv i-source-000]: timed out waiting for the condition

Reproducer:

# https://github.com/abouchama/fusedashboard/blob/master/prometheus-jmx-exporter.yaml
oc create configmap prometheus-vol --from-file=prometheus-jmx-exporter.yaml

kamel run --name greetings --configmap=prometheus-vol --dependency=camel-rest --dependency camel-undertow --property camel.rest.port=8080 --open-api greetings-api.json --trait prometheus.enabled=true --trait prometheus.configmap=prometheus-vol --trait prometheus.service-monitor=true --trait prometheus.service-monitor-labels=app=greetings greetings.groovy

@abouchama I think the problem here is that the root property in the prometheus configmap is called rules, while Camel K expects it to be called content.

Can you verify?

[abouchama]

Strange, I have changed rules with content and even though the same error:

MountVolume.SetUp failed for volume "i-resource-000" : configmap references non-existent config key: content

[abouchama]

Got it, we have to change the filename with content in the configmap
e.g;
from

data:
  prometheus-config.yaml: |

to

data:
  content: |
