📝 Walkthrough

Walkthrough

The UBI 9 Dockerfile updates Go to 1.26.8 and installs pinned versions of gopls, goimports, and dlv with CGO disabled. The UBI 10 Dockerfile installs those tools at pinned versions with CGO disabled on all architectures.

Changes

Go toolchain updates

Layer / File(s) Summary
Go toolchain and tools
universal/ubi9/Dockerfile, universal/ubi10/Dockerfile
The UBI 9 image updates Go to 1.26.8 and installs gopls@v0.23.0, goimports@v0.50.0, and dlv@v1.27.2 with CGO disabled. The UBI 10 image installs the same pinned tools with CGO disabled on all architectures, and stops the build if an installation fails.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: ⚪ Minimal · up to 319f8

The images install pinned Go tools across their supported architectures, with no established current-head issue. Full image builds were not run, so normal build validation remains appropriate.

Review details

Systems and components

  • observed — universal (service) was modified; 2 changed files map to changed impact.

Before / after behavior

  • observed — Modified behavior in universal/ubi10/Dockerfile: The ppc64le-specific branch and the non-ppc64le installation path are removed. All architectures now install gopls@v0.23.0, goimports@v0.50.0, and dlv@v1.27.2 with CGO_ENABLED=0; the installations are chained so a failed command stops the build.
  • observed — Modified behavior in universal/ubi9/Dockerfile: The Go version changes from 1.22.5 to 1.26.8. The gopls install changes from version 0.16.2 to 0.23.0; goimports 0.50.0 and dlv 1.27.2 are added. Each tool installation now sets CGO_ENABLED=0.

Pin the Go tools when reproducible image contents are required.

@latest can install different gopls, goimports, and dlv versions during later rebuilds. Select versions tested with Go 1.26.8 and pin all three tools in both Dockerfiles. Do not reuse the README's older gopls versions without testing them against the new toolchain.
