Upgrading Golang Version
This skill automates the comprehensive Go version upgrade process across all components of the Chainloop project.
Process
1. Confirm Target Versions
Ask the user:
- What Go version they want to upgrade to (e.g., "1.25.3")
- Whether they also want to upgrade Atlas migrations Docker image (if yes, ask for target Atlas version, e.g., "0.38.0")
2. Get Docker Image Digest
Pull the official golang Docker image and extract its SHA256 digest:
bash
docker pull golang:X.XX.X
Extract the SHA256 digest from the output (format:
).
3. Update Source Code
IMPORTANT: Do NOT update
per project policy.
Pattern to replace:
4. Update Docker Images
Update all Dockerfiles with the new version and SHA256 digest. See files-to-update.md for the complete list.
Pattern to replace:
dockerfile
FROM golang:X.XX.X@sha256:OLD_DIGEST AS builder
With:
dockerfile
FROM golang:X.XX.X@sha256:NEW_DIGEST AS builder
5. Update GitHub Actions
Update
in all workflow YAML files. See
files-to-update.md for the complete list.
Pattern to replace:
6. Update Documentation
Update the version reference in
under "Key Technologies":
markdown
- **Language**: Go X.XX.X. To know how to upgrade go version, see docs/runbooks
7. Update Atlas Docker Image and CLI (Optional)
If the user requested an Atlas upgrade:
7a. Pull the Atlas Docker image and extract its SHA256 digest:
bash
docker pull arigaio/atlas:X.XX.X
Extract the SHA256 digest from the output (format:
).
7b. Update ./app/controlplane/Dockerfile.migrations
Pattern to replace:
dockerfile
# from: arigaio/atlas:X.XX.X
# docker run arigaio/atlas@sha256:OLD_DIGEST version
# atlas version vX.XX.X
FROM arigaio/atlas@sha256:OLD_DIGEST as base
With:
dockerfile
# from: arigaio/atlas:X.XX.X
# docker run arigaio/atlas@sha256:NEW_DIGEST version
# atlas version vX.XX.X
FROM arigaio/atlas@sha256:NEW_DIGEST as base
IMPORTANT: Before updating the version in common.mk, ALWAYS test that the Atlas version is available via the curl command:
bash
curl -sSf https://atlasgo.sh | ATLAS_VERSION=vX.XX.X sh -s -- --version
If the command fails or the version is not available, do NOT update common.mk. Only the Docker image should be updated in this case.
Update the Atlas CLI installation version in the
target:
Pattern to replace:
makefile
curl -sSf https://atlasgo.sh | ATLAS_VERSION=vX.XX.X sh -s -- -y
With the new version (note: use
prefix for the version):
makefile
curl -sSf https://atlasgo.sh | ATLAS_VERSION=vX.XX.X sh -s -- -y
8. Verify Changes
Run verification commands:
If errors occur, address them before completing the upgrade.
9. Final Checks
- Ensure all license headers are updated (2024 → 2024-2025 or add current year)
- Run if any proto files were affected
- Run if any constructor dependencies changed
- Verify changes with
Important Notes
- Always use SHA256 digests for Docker images for security and reproducibility
- The dagger module () must NOT be updated
- Test thoroughly as Go upgrades can introduce breaking changes
- Multiple components use Go: CLI, Control Plane, and Artifact CAS
