Grafana Loki sink Label Expansion issue with helm chart

[Amikuto]

Hello!

I'm trying to deploy Vector via helm chart.
I need to add some labels to Loki. According to your documentation I need to add the following value to values.yaml file:

labels: 
    k8s_container_name: {{ kubernetes.container_name  }}

But this configuration crashes with the help error, Helm does not see the kubernetes.container_name function.
I found the following solution to the problem.

k8s_container_name: '"{{ "{{" }} kubernetes.container_name {{ "}}" }}"'

However, now the following value is in the config map:

k8s_pod_namespace: '"{{ kubernetes.pod_namespace }}"'

Unfortunately, with a single quote, vector does not see this configuration and I do not receive any logs at all

Could you help me please?

I believe:

k8s_container_name: "{{ "{{" }} kubernetes.container_name {{ "}}" }}"

Should work. I would check what the config map ends up being rendered with.

Solution that works for me

"k8s_pod_name": "{{`{{kubernetes.k8s_pod_name}}`}}"
