chore: enable SBOM attestation for image builds (coder#16852)

matifali · web-flow · commit 05ebece03ad2 · 2025-03-11T00:24:14.000+05:00
- Added SBOM (Software Bill of Materials) generation during Docker build to enhance traceability. Refer to Docker documentation on SBOM: https://docs.docker.com/build/metadata/attestations/sbom/ - Updated Docker build scripts to use BuildKit for provenance and SBOM support: https://docs.docker.com/build/metadata/attestations/ - Configured Docker daemon in dogfood image to support the Containerd snapshotter feature to improve performance: https://docs.docker.com/engine/storage/containerd/ > [!Important] > We also need to enable `containerd` on depot runners. > <img width="587" alt="image" src="https://github.com/user-attachments/assets/1d7f87c7-fdcc-462a-babe-87ac6486ad09" /> ## Testing - Tested locally with ` docker buildx build --sbom=true --output type=local,dest=out -f Dockerfile .` to verify that an SBOM file is generated. - Tested in [CI](https://github.com/coder/coder/actions/runs/13731162662/job/38408790980?pr=16852#step:17:1) to ensure the image builds without any errors. Also closes coder/internal#88
