Getting Error While Deploying Raw Yaml to Kubernetes with Variable for config map

[selcuk.kubur]

Hi Community ,

Im trying to deploy raw yaml to kubernates cluster under stored on rancher for specific namespace.

I could deploy without using any volume mounts and config map (using for volume) but couldn’t be successfully with using stored config map on rancher for under this namespace value.

my release created from teamcity successfully.

Im getting array error on validation in this step , any suggest to me? would be appreciated

ValidationError(Deployment.spec.template.spec.containers): invalid type for io.k8s.api.core.v1.PodSpec.containers: got “map”, expected “array”; if you choose to ignore these errors, turn validation off with --validate=false

Hi @selcuk.kubur,

Thanks for getting in touch!

With you mentioning that the error occurs after adding the volume mount and config map, and with the error stating got “map”, expected “array” my best guess would be to change the configMap from a map to an array. The examples I can find of the volumes and configMap seem to suggest it needs to be an array too.

e.g.

  volumes:
    # You set volumes at the Pod level, then mount them into containers inside that Pod
    - name: config
      configMap:
        # Provide the name of the ConfigMap you want to mount.
        name: game-demo

I hope this helps.

Regards,
Paul
