All in all, a very clean and nice build Helm Chart 👍

What do you think about installing ingress-nginx with Tilt and keeping the values so that you can use Tilt without any adjustments?

For this you would have to set the insecure flag so that you don't have to generate a key and install an ingress controller and set * as host.

tilt/namespace.yaml:

...

---
apiVersion: v1
kind: Namespace
metadata:
  name: ingress-nginx

tilt/scrumlr-values.yaml:

backend:
  config:
    natsUrl: nats://nats.nats.svc.cluster.local:4222
  secrets:
    databaseUrl: postgres://postgres:SuperStrongpassword@postgres-postgresql.postgres.svc.cluster.local:5432/scrumlr?sslmode=disable
  extraConfig:
    # Do NOT use this config for production deployments, this flag enables hardcoded, insecure keys
    SCRUMLR_INSECURE: true
ingress:
  enabled: true
  annotations:
    # Websocket optimization https://kubernetes.github.io/ingress-nginx/user-guide/miscellaneous/#websockets
    nginx.ingress.kubernetes.io/proxy-send-timeout: "7200"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "7200"
  hostname: "*"
  ingressClassName: "nginx"

tilt/Tiltfile:

load("ext://helm_resource", "helm_resource", "helm_repo")

helm_repo("nats-repo", "https://nats-io.github.io/k8s/helm/charts/")
helm_repo("ingress-nginx-repo","https://kubernetes.github.io/ingress-nginx")

k8s_yaml(yaml="./namespace.yaml")

helm_resource(
    name="postgres",
    chart="oci://registry-1.docker.io/bitnamicharts/postgresql",
    namespace="postgres",
    flags=["--values=postgres-values.yaml"],
)

helm_resource(
    name="nats-deploy",
    release_name="nats",
    chart="nats/nats",
    namespace="nats",
    resource_deps=["nats-repo"],
)

helm_resource(
    name="ingress-nginx-deploy",
    release_name="ingress-nginx",
    chart="ingress-nginx/ingress-nginx",
    namespace="ingress-nginx",
    resource_deps=["ingress-nginx-repo"],
)

yaml = helm(
    "./../../scrumlr",
    name="scrumlr",
    namespace="scrumlr",
    values=["./scrumlr-values.yaml"]
)
k8s_yaml(yaml=yaml)

Other small things I would change/ nits:

• Rename the k8s directory to helm. Especially with the background that I might want to contribute a current Kustomize deployment (mainly for SKE).
• Inconsistent End of File, the .editorconfig in this repo also suggests a newline at the end of files
