Update Go Version

Updates the Go version across all relevant files in the Tempo codebase.

Usage

Invoke with /update-go-version

Steps to Perform

1. Get the version

Extract Go version from tools/Dockerfile.

This file is updated by a Renovate workflow automatically.

2. Check if go.mod files need updating

Check these files:

• go.mod (main module)
• tools/go.mod (tools module) If the versions already match, advise user that tools/Dockerfile needs to be updated and merged first to build new image, then stop.

3. Update go.mod files

Update the go X.Y.Z directive in both:

• go.mod (main module)
• tools/go.mod (tools module)

4. Update TOOLS_IMAGE_TAG in build/tools.mk

Fetch the latest tools image tag from Docker Hub:

curl -s "https://hub.docker.com/v2/repositories/grafana/tempo-ci-tools/tags?page_size=5&ordering=last_updated" | jq -r '.results[0].name'

Update TOOLS_IMAGE_TAG ?= main-XXXXXXX with the latest tag.

5. Verify changes compile

make vendor
make build
