fix(cassandra): rebuild migration kubectl with patched Go#1610sbaum1994 wants to merge 3 commits into
Conversation
Update kubectl from 1.36.4 to 1.37.0. The official 1.37.0 binaries are built with Go 1.26.6 and remain checksum pinned for amd64 and arm64. Keep kubectl in the runtime image because the Cassandra initialization hook uses this image to run initdb.sh. Signed-off-by: Stephanie Baum <sbaum@nvidia.com>

Risk assessment: moderate build risk, low runtime risk.
Overall, the larger source-build path is a deliberate build-time tradeoff. Runtime behavior and the supported cluster window stay stable while the reported Go vulnerability floor is removed. |

In `@migrations/cassandra/tests/test-execute-sqls.sh`:
- Around line 96-98: Update the kubectl validation in the initialization-script
test to require an actual kubectl exec operation rather than any standalone
kubectl token, while retaining the existing failure behavior when it is absent.
- Around line 106-108: Update the migrations image baseline check around the
KUBECTL_VERSION assertion to require a Kubernetes release built with Go 1.26.6
or later, and update both architecture-specific image digests to matching
artifacts. Validate each artifact’s build metadata rather than checking only the
KUBECTL_VERSION value.

Run each target-architecture kubectl binary during the image build and require GitVersion v1.37.0 with Go 1.26.6 or newer. Tighten the chart contract test to require the non-comment kubectl exec operation used by cluster initialization. Signed-off-by: Stephanie Baum <sbaum@nvidia.com>

In `@migrations/cassandra/Dockerfile`:
- Line 27: Update the kubectl version handling near ARG KUBECTL_VERSION so it
aligns with the Kubernetes server versions supported by Cassandra deployments:
either document or enforce the v1.36–v1.38 server range, or select a client
version compatible with the broader deployment range.

Rebuild Kubernetes kubectl v1.36.4 from its checksum-pinned official source with Go 1.26.6. This retains compatibility with supported Kubernetes v1.35 through v1.37 clusters while clearing the vulnerable Go runtime metadata. Signed-off-by: Stephanie Baum <sbaum@nvidia.com>

TL;DR
Additional Details
kubectl getandkubectl exec; removing kubectl would break first-install initialization.GOPROXY=off, upstream release tags,-trimpath, and an empty build ID.Kubernetes and Go remain existing Apache-2.0/BSD-licensed dependencies. No new dependency or NOTICE change is required.
For the Reviewer
Review the source provenance and metadata checks in
migrations/cassandra/Dockerfile, plus the hook-to-image contract assertion intest-execute-sqls.sh.For QA
No separate QA is required beyond CI. Local validation:
sh migrations/cassandra/tests/test-execute-sqls.shshellcheck migrations/cassandra/tests/test-execute-sqls.shgit diff --checkkubectl-builderbuild forlinux/amd64,linux/arm64The full Bazel suite was not run because this subtree is built and tested through its Dockerfile and shell contract test.
