How to express field_path to complex label name?

[worldspawn]

Hello,

I would like to know how this should be written.

env {
            name = "ORLEANS_CLUSTER_ID"
            value_from {
              field_ref {
                field_path = "metadata.labels['orleans/clusterId']"
              }
            }
          }

This results in a literal value of metadata.labels['orleans/clusterId']. I can't find any examples for such a scenario. Is it supported?

Have also tried "metadata.labels.'orleans/clusterId'" "metadata.labels.orleans/clusterId" but they fail on run.

If this can/cannot be done could you also add a note in the relevant section deployment and/or pod documentation.

Terraform version, Kubernetes provider version and Kubernetes version

Terraform version: 0.14.6
Kubernetes Provider version: 2.0.2
Kubernetes version: 1.19.7

Are you able to get this to work outside of Terraform using YAML? I can't find any documented example of a fieldPath with a slash in it which leads me to suspect that this might not be possible.

The docs do have an example of using a volume to get the pod labels – that might be a possible workaround: https://kubernetes.io/docs/tasks/inject-data-application/downward-api-volume-expose-pod-information/#store-pod-fields

@worldspawn did you ever find a solution to this? I'm coming up against the same issue.

No I gave up 🤷‍♂️
