ko v0.19 unconditionally attempts HTTPS when writing SBOMs, causing the E2E job to fail with "http: server gave HTTP response to HTTPS client" against the plain-HTTP KinD registry (registry.local:5000). Set KO_FLAGS=--insecure-registry in the e2e-matrix env block so that both image pushes and SBOM writes use plain HTTP for the local registry. The flag is already forwarded to `ko apply` via $(KO_FLAGS) in the Makefile apply target, so no Makefile change is needed.

This is a cherry-pick of #3621
Changes
ko v0.19 unconditionally attempts HTTPS when writing SBOMs, which causes
the E2E job to fail with:
against the plain-HTTP KinD registry (
registry.local:5000).Root cause:
ko-build/setup-ko(without a pinnedversion:) picked upko v0.19.1, which introduced mandatory SBOM writes via cosign. cosign uses
HTTPS by default and has no knowledge that
registry.local:5000is a plainHTTP endpoint, so every SBOM push fails.
Fix: set
KO_FLAGS=--insecure-registryin thee2e-matrix.ymljob env.This flag is already forwarded to
ko applyvia$(KO_FLAGS)in theMakefile
applytarget — no Makefile change is required. The flag is scopedto the CI job only; local
make applyagainst production registries (quay.io,ghcr.io) is unaffected.
The fix was verified locally by reproducing the failure against a custom-hostname
plain-HTTP registry and confirming success with the flag set.
