### Summary Speed up repeated local builds of `backend/Dockerfile.local` (used by `docker-compose-dev-mysql.yml` and `docker-compose-dev-postgresql.yml`) by caching Go modules and the Go build cache with BuildKit. ### Changes | Where | Change | |---|---| | `backend/Dockerfile.local` | download modules in a separate step that only depends on `go.mod`/`go.sum` | | `backend/Dockerfile.local` | BuildKit cache mounts for `/go/pkg/mod` and `/root/.cache/go-build` in the `make mock`, `make swag`, `make build-plugin` and `make build-server` steps | Without these changes, every source change invalidates `COPY . /app`, so all modules are downloaded again and all plugins are compiled from scratch. With the cache mounts, Go only rebuilds the packages that changed. `backend/Dockerfile` already uses the same go-build cache mount. The image content is unchanged. The file is not used by CI or the release images, so CI does not exercise it. ### Verification Docker 29.5.3 (BuildKit), VM with 2 CPUs / 5 GB, `main` @ `aaca6bd5c` vs. this branch. "Rebuild" = one line appended to `plugins/github/impl/impl.go` (a real content change; `touch` alone does not invalidate `COPY`). | Check | `main` | this PR | |---|---|---| | Build from scratch (`--no-cache`, empty cache mounts) | 434 s | 529 s (includes the separate `go mod download`; noisy on a 2-CPU VM) | | Rebuild after changing one plugin file | **330 s** | **93 s** | | — `make mock` / `make swag` | 47 s / 20 s | 3 s / 4 s | | — `make build-plugin` | 211 s | 72 s | | — `make build-server` | 28 s | 6 s | | Image: same file list under `/app` and `/usr/local/lib` | — | ✅ identical (51 files) | | Run against PostgreSQL 18.6: `GET /ping`, `GET /proceed-db-migration`, 47 plugins loaded (`GET /plugins`), no panic/fatal | ✅ | ✅ | The `FROM … as builder` casing is left untouched so this does not conflict with #9217. -- This is an automated message from the Apache Git Service.
