kepler's CI build and lint jobs are pinned to Go 1.24. The Dockerfile uses golang:1.24 and golangci-lint is on v2.1.6. When go.mod moves past 1.24 (dependabot bumped x/net to v0.55.0, which needs Go 1.25), both jobs break.

Bumped the Dockerfile base image to golang:1.25, and golangci-lint to v2.9.0 in .pre-commit-config.yaml. golangci-lint v2.9.0 builds against Go 1.25.

Covers the first checkbox from #2491. The Go 1.26 step needs goreleaser and other tooling to catch up, so splitting that out makes sense.

The CI workflow file (.github/workflows/pr-checks.yaml) also pins golangci-lint to v2.1.6 and should be bumped to v2.9.0 in the same pass. Same one-line change. Happy to push that as a follow-up commit or have a maintainer apply it directly.

We also need to update the go version in go.mod as well

Hi @molloyzak13! Thanks for opening this PR to keep our dependencies up to date.

I noticed you bumped the builder image to golang:1.25 in the Dockerfile, but the go.mod file is still set to go 1.24.0. Because all of our GitHub Actions workflows use go-version-file: go.mod to resolve the Go version, this creates a split-brain scenario: our CI and tests will continue running on Go 1.24, while the production Docker images will build with Go 1.25.

To ensure our CI accurately reflects the production build environment, could you also run go mod edit -go=1.25.0 (and update the toolchain version if necessary) so that go.mod is in sync with the Dockerfile?

Thanks again!

Signed the DCO and bumped go.mod to go 1.25.0 to match the Dockerfile builder image. Dropped the old toolchain go1.24.9 line since it's redundant with the new go directive. Ran make deps (go mod tidy + go mod verify) and everything resolves cleanly. Thanks for catching the mismatch.

Ah yep, the DCO sign-off landed in the commit message body but not as a proper Signed-off-by trailer. I'll amend the commits with -s and push. One sec.

Done. Amended all three commits with -s so the DCO check should pick up the Signed-off-by trailers now. No code changes, just the sign-off metadata. Thanks for the nudge.

Pushed. go.mod is at go 1.25.0 and all commits have proper Signed-off-by trailers now. DCO check is green. No other changes. Ready for another look when you get a chance.

@molloyzak13 Thank you for the PR. You would need to update lint version here too.

kepler/.github/workflows/pr-checks.yaml

Line 62 in 96430b4

version: v2.1.6

@molloyzak13 could you implement @sunya-ch's review feedback please?

Edit: Actually I just noticed this is covered by the other similar PR: https://github.com/sustainable-computing-io/kepler/pull/2496/changes#diff-7a6a4578fe04c4fc86b28e2dc9672e48d1a9f721315e540b90bac0ef12263053R62

So perhaps we just need to merge both at the same time
