Bug

Description

If you follow steps here: https://repo1.dso.mil/platform-one/big-bang/bigbang/-/blob/master/docs/guides/deployment_scenarios/quickstart.md

up to the point where you terraform apply It'll get stuck module.big_bang.data.external.Wait_for_load_balancer: Still reading... [10h11m4s elapsed]

After sshing into the k3d VM I:

• Checked namespaces and only saw flux-system, bigbang, and kube default namespaces.
• I verified registry1 creds and that images were being pulled correctly
• k describe hr bigbang -n=bigbang

BigBang Version

What version of BigBang were you running?

• 1.11.0, but the error message makes me think it could be touching latest code some how.
• Proof of 1.11.0:

kubectl get gitrepository -n bigbang
# NAME               URL                                                                    READY   STATUS                                                              AGE

Note the error message: Message: Helm install failed: template: bigbang/templates/istio/controlplane/secret-tls.yaml:1:46: executing "bigbang/templates/istio/controlplane/secret-tls.yaml" at <.Values.istio.ingress.key>: nil pointer evaluating interface {}.key

Made me look in the repo: https://repo1.dso.mil/platform-one/big-bang/bigbang/-/blob/662b13db5b0c3e41de8e44d3e2f3d79897da524b/chart/templates/istio/controlplane/secret-tls.yaml https://repo1.dso.mil/platform-one/big-bang/bigbang/-/blob/e75fc5d185d985ff54f589d250439496654b72e3/chart/templates/istio/controlplane/secret-tls.yaml

^-- This seems to be the file referenced. There was a change about 2 days ago that looks like it could result in a nil pointer type error, but the only way that logic could possibly happen is if it was trying to deploy latest, when it should be pinned to a specific version.
