I'm trying to use the langfuse helm chart in my Tiltfile and, although it launches appropriately, I'm having trouble forwarding the port to the web pod specifically. I use k8s_resource to refer to the workload and use extra_pod_selectors to select the specific pod, but it always ends up selecting a random pod to forward the port to.
Here is the first part that applies the helm chart:
helm_repo("langfuse-repo", "https://langfuse.github.io/langfuse-k8s", labels=["langfuse"])
helm_resource(
"langfuse",
"langfuse-repo/langfuse",
resource_deps=["langfuse-repo"],
namespace="langfuse",
labels=["langfuse"],
deps=["configurations/langfuse.yaml"],
flags=[
"--create-namespace",
"--values=configurations/langfuse.yaml",
],
)
I can see that one pod should be selectable by the following label:
> kubectl get pods -l app=web -n langfuse
NAME READY STATUS RESTARTS AGE
langfuse-web-5897965c8c-drwcn 1/1 Running 0 4h37m
So I add this after the helm_resource call:
k8s_resource(
"langfuse",
port_forwards=3000,
extra_pod_selectors=[{"app": "web"}],
labels=["langfuse"],
)
This does then create a PortForward in tilt, but it will randomly apply it to one of the pods created by the langfuse helm chart. I.e. clickhouse or worker or zookeeper:
> tilt get PortForward
NAME CREATED AT
langfuse-langfuse-clickhouse-shard0-0 2025-10-17T02:41:07Z
What am I doing wrong to properly select the single web pod when applying the port forward?
