WalkthroughUpdated docker_build_image_version in cookiecutter.json. Upgraded template go.mod dependencies across gRPC, Protobuf, OpenTelemetry, Prometheus, golang.org/x, and internal packages; added new indirect dependencies (backoff/v5, yaml v3). No source code or public API changes. Changes

- Updated default Go version from 1.24 to 1.25 in the cookiecutter template
- Updated multiple Go dependencies including gRPC, Protocol Buffers, OpenTelemetry, and Prometheus libraries
- Added new indirect dependencies to support updated packages

🧹 Nitpick comments (2)
cookiecutter.json (1)
8-8: Nit: avoid using alpine:latest for reproducible builds.Pin the base image to a specific Alpine release (e.g., major.minor) to prevent surprise changes when “latest” moves. Optional but recommended for stability.
{{cookiecutter.app_name}}/go.mod (1)
3-3: Templating the Go version is fine; consider decoupling naming and adding toolchain (optional).Using docker_build_image_version for the go directive works because Cookiecutter selects a single value. To improve clarity, consider a separate go_version variable, and optionally add a toolchain directive for consistent compiler resolution.
Apply this minimal change (keep existing variable if you prefer):
-go {{cookiecutter.docker_build_image_version}} +go {{cookiecutter.docker_build_image_version}} +toolchain go{{cookiecutter.docker_build_image_version}}.0Optionally, if you want to decouple variables (requires updating cookiecutter.json too):
-go {{cookiecutter.docker_build_image_version}} +go {{cookiecutter.go_version}}And in cookiecutter.json (additional change outside this hunk), define a distinct go_version:
{ "go_version": ["1.25", "1.24"], "docker_build_image_version": ["1.25", "1.24"] }

cookiecutter.json (1)
10-10: Approve — Go 1.25 added and templates look alignedQuick verification performed across the repo:
- cookiecutter.json contains the updated matrix:
"docker_build_image_version": ["1.25", "1.24"]- Templates use the cookiecutter variable (so the default/first choice "1.25" will be applied):
- {{cookiecutter.app_name}}/Dockerfile: FROM {{cookiecutter.docker_build_image}}:{{cookiecutter.docker_build_image_version}}
- {{cookiecutter.app_name}}/go.mod: go {{cookiecutter.docker_build_image_version}}
- No .github/workflows directory or hard-coded FROM golang:* images were found by the repo-wide scan.
Action: No changes required in this template repo. If you maintain downstream CI pipelines or external repos generated from this template, update their setup (actions/setup-go, Dockerfiles, or other CI configs) to use Go 1.25 as needed.
{{cookiecutter.app_name}}/go.mod (4)
288-295: Large OpenTelemetry upgrades; verify any sample/instrumentation code remains compatible.The OTEL modules jumped to v1.37.0. If the template includes sample traces/metrics or generated code, double-check usage and configuration flags remain valid. No blocker if the template has no such code.
224-227: Prometheus bumps; watch for minor API/semantic changes.client_golang v1.23.0 and friends can introduce small changes (e.g., histograms, collectors). If the template exports any metrics helpers, sanity-check registration and collectors. Otherwise safe to proceed.
70-72: Both backoff/v4 and backoff/v5 are indirect — no direct imports foundrg search returned matches only in go.mod and go.sum; no .go source files import github.com/cenkalti/backoff/v4 or /v5.
- Checked locations:
- {{cookiecutter.app_name}}/go.mod — lines 70–71: backoff/v4 v4.3.0 // indirect and backoff/v5 v5.0.3 // indirect
- {{cookiecutter.app_name}}/go.sum — entries referencing both v4 and v5 (grep hits around lines 1489–1493)
Action: none required — coexistence is transitive and safe as-is.
312-313: Deprecated x/tools entries are indirect only — no direct usage found.Quick check (rg) shows these modules only appear as indirect entries in go.mod/go.sum; there are no direct imports in the template.
Files to note:
- {{cookiecutter.app_name}}/go.mod (lines 312–313)
golang.org/x/tools/go/expect v0.1.1-deprecated // indirect golang.org/x/tools/go/packages/packagestest v0.1.1-deprecated // indirect
- {{cookiecutter.app_name}}/go.sum (entries referencing those modules at lines ~3328–3331)
Recommendation (optional): leave as-is since they’re indirect, or run
go mod tidy/ update the toolchain dependency (golang.org/x/tools v0.36.0 is present indirectly) to prune/update these if you want to remove deprecated artifacts. Not a blocker.
