Five changes to the scaffold every future chart is copied from:
1. seccompProfile.type: RuntimeDefault in the pod security context, in
line with the rest of the seccomp series (#84). Pod context, because
from there it also covers init containers and any container added
later without being repeated.
2. containerPort 80 -> 8080, clearing AVD-KSV-0117. Note that the usual
justification for this does not hold: a non-root container CAN bind
port 80 on current Kubernetes, because the kubelet sets
net.ipv4.ip_unprivileged_port_start=0 in the pod network namespace.
Measured, not assumed - see the values.yaml comment. The reason to
stay above 1024 is that this is a runtime default rather than a
guarantee, and that every real chart here already does.
3. The ConfigMap placeholder key is renamed from the literal "key" to
"example-setting", clearing AVD-KSV-01010 (secret-scanner patterns
match any key named "key").
4. The image placeholder is fully qualified as ghcr.io/ORG/IMAGE, so the
template stops teaching the unqualified form that produced the
repo's unqualified Docker Hub images.
5. env values are rendered through "quote". Without it a value like
"8080" renders as a YAML number and the API server rejects the whole
manifest ("cannot unmarshal number into Go struct field
EnvVar.value of type string"). Every real chart in the repo already
quotes here; only the template did not. Found by instantiating the
template and installing it, not by rendering it.
Verified by instantiating the scaffold into a working chart per the
README procedure and installing it in k3d: the workload becomes Ready,
the Service routes to the app on 8080 and an ephemeral container added
to the running pod inherits Seccomp: 2 from the pod context.
