Patch version bump of the Go Docker base image (1.26.3 → 1.26.5) in the build stage of the Dockerfile.

Summary

This is a mechanical, Renovate-generated dependency update that bumps the Go builder image by two patch versions. The change is a single-line tag swap with no behavioral, API, or architectural impact.

Correctness: No logic, edge-case, or build risks introduced. The go.mod directive (go 1.26.3) specifies a minimum Go version; building with 1.26.5 satisfies it. Other files referencing 1.26.3 (.tool-versions, Dockerfile.dist, module files) remain valid — patch versions are backward-compatible and will be updated by their own Renovate PRs.

Security: No secrets, permissions, workflows, or auth-related files are modified. The mutable-tag pattern (:1.26.5 without a digest pin) is consistent with the pre-existing convention; no new risk is introduced by this PR.

Intent & coherence: Automated patch maintenance by Renovate bot — authorization is implicit in the mechanical nature of the change and the project's configured auto-merge policy.

Style & conventions: The new value follows the identical major.minor.patch tag pattern as the previous value. No style deviation.

Documentation: No user-facing documentation references the specific Go builder image version. No staleness introduced.

No findings above the severity threshold.

PR: #3372 — Update docker.io/library/golang Docker tag to v1.26.4 (main)
Author: red-hat-konflux[bot] (Renovate / MintMaker)
Scope: 1 file changed, 1 addition, 1 deletion

Summary

Routine patch version bump of the Go build base image in the Dockerfile from golang:1.26.3 to golang:1.26.4. This is an automated dependency update created by the MintMaker/Renovate bot.

Analysis

Dimension	Result
Correctness	✅ Single-line tag bump in the build stage. Go patch versions are backward compatible. The go.mod directive (go 1.26.3) specifies minimum version and is fully compatible with the 1.26.4 toolchain.
Security	✅ Patch updates typically include bug and security fixes. Updating promptly is best practice.
Intent & coherence	✅ Standard automated dependency update. Well-scoped, single-purpose change.
Style & conventions	✅ Follows existing Dockerfile patterns. Tag-based reference is consistent with the build stage convention in this repo.
Documentation	✅ No documentation impact.
Cross-repo contracts	✅ No API, schema, or interface changes.

Findings

No findings.

Scope: Automated patch version bump of Go Docker base image (1.26.3 → 1.26.5) in Dockerfile.

Summary

This is a single-line, automated Renovate/MintMaker dependency update that bumps the Go compiler Docker image tag from 1.26.3 to 1.26.5. Patch version updates deliver bug fixes and security patches with no breaking changes.

Analysis

Dimension	Assessment
Correctness	✅ Syntactically valid FROM instruction. go.mod specifies go 1.26.3 as minimum — building with 1.26.5 is fully compatible.
Security	✅ Patch releases include security fixes. No new attack surface. Net-positive change.
Intent & coherence	✅ Standard automated dependency update from red-hat-konflux[bot]. Branch name, labels, and PR body all consistent.
Style / conventions	✅ No changes to code style. Maintains existing Dockerfile format.
Documentation	✅ No documentation updates needed for a base image tag bump.
Cross-repo contracts	✅ No API, schema, or interface changes.

No findings above the severity threshold.

Review — ✅ Approve

Scope: Automated patch version bump of the docker.io/library/golang Docker base image from 1.26.3 to 1.26.4 in Dockerfile.

Analysis

Dimension	Assessment
Correctness	Single-line base image tag bump. Go patch versions are backward compatible; building with Go 1.26.4 while go.mod specifies go 1.26.3 is fully supported. No logic changes.
Security	Patch updates typically include security and bug fixes — this update is beneficial.
Intent & coherence	Properly scoped automated Renovate update. Other version references (go.mod, .tool-versions, Dockerfile.dist) use different package managers or images (ubi9/go-toolset) and are managed by separate Renovate rules. No consistency issue.
Style	Matches existing Dockerfile conventions (full docker.io/library/ prefix, tag-only versioning).
Documentation	No documentation changes required.
Cross-repo contracts	Not applicable — no API or schema changes.

Notes

• The Dockerfile is the only file referencing docker.io/library/golang — no other files were missed.
• Dockerfile.dist uses a different base image (ubi9/go-toolset) with its own digest pin, managed separately.
• The go.mod files specify the Go language version directive, not the Docker image version — these are independently managed and the slight version difference is expected and safe.

No findings. Safe to merge.

Review of #3372 — Update docker.io/library/golang Docker tag to v1.26.5

Verdict: ✅ Approve

Summary

This is an automated patch version bump of the Go Docker build image from 1.26.3 to 1.26.5, generated by MintMaker/Renovate. The change modifies a single line in the Dockerfile.

Dimensions reviewed

Dimension	Findings
Correctness	✅ No issues — patch bump is compatible with go.mod minimum version (go 1.26.3 ≤ 1.26.5)
Security	✅ No issues — no secrets, injection vectors, auth/permission changes
Intent & coherence	✅ Mechanical dependency update; authorization implicit
Style & conventions	✅ Change follows existing Dockerfile patterns
Documentation currency	✅ No documentation references the Go version
Cross-repo contracts	✅ No exported interfaces or API surfaces modified

Notes

• The Go version in go.mod (1.26.3) is a minimum version directive and is compatible with the updated Docker image (1.26.5). Renovate typically updates these independently.
• The build stage uses a tag without a digest pin, while the final stage (ubi9/ubi-minimal) is digest-pinned. This is a pre-existing pattern, not introduced by this PR.

Review

Outcome: Approve

Summary

Mechanical patch-version bump of the Go build image from golang:1.26.3 to golang:1.26.4 in Dockerfile, generated by MintMaker/Renovate. The change is a single-line value substitution that follows the existing pattern. No logic, security, API, or documentation concerns.

Findings

Severity	Category	File	Description
low	version-consistency	Dockerfile:19	The Dockerfile is bumped to golang:1.26.4, while Dockerfile.dist still uses go-toolset:1.26.3, and go.mod / .tool-versions also reference 1.26.3. For a Go patch release this is benign — go.mod's go directive is a minimum-version floor, and Renovate manages each dependency independently. No action needed on this PR; the other files will be updated by their own Renovate PRs.

Dimensions evaluated

• Correctness: No logic, edge-case, or test-integrity concerns. The only observation is the expected cross-file version skew noted above.
• Security: No secrets, injection patterns, permission changes, or supply-chain concerns introduced. The mutable tag (no digest pin) on the golang build image is a pre-existing pattern not introduced by this PR.
• Intent & coherence: Mechanical dependency bump by an automated bot. Authorization is implicit from the change's nature.
• Style & conventions: Value-only change follows existing Dockerfile pattern exactly.
• Documentation currency: No documentation impact.
• Cross-repo contracts: No exported interfaces or APIs modified.

Low-severity Observations

1. Go version skew — Dockerfile.dist (Dockerfile, line 19): This PR bumps Dockerfile to Go 1.26.4 while Dockerfile.dist still uses ubi9/go-toolset:1.26.3 (pinned by digest). These are different base images managed by separate Renovate rules, so the temporary skew is expected and will resolve when the go-toolset:1.26.4 image is published and picked up.

2. Go version skew — go.mod / .tool-versions (Dockerfile, line 19): Several files (.tool-versions, go.mod, tools/go.mod, tools/kubectl/go.mod, acceptance/go.mod) still reference Go 1.26.3. These are managed independently and the patch-level discrepancy is benign for Go's compatibility guarantees.

Findings

High

• [protected-path] Dockerfile:19 — This PR modifies Dockerfile, which is a protected infrastructure file requiring human approval. The PR has no linked issue providing authorization for the change. While the PR is a Renovate-managed patch bump of the Go base image (1.26.3 → 1.26.4), protected-path changes always require explicit human review and approval regardless of the change's nature.
  Remediation: A human reviewer with infrastructure approval authority should verify and approve this Dockerfile change.

Review

Findings

Medium

• [protected-path] Dockerfile — This PR modifies Dockerfile, which is a protected path requiring human approval. The PR is an automated Renovate dependency update (golang 1.26.3 → 1.26.4) with a clear rationale in the PR body, but human review is always required for changes to governance and infrastructure files regardless of context.
