CRITICAL FIX: arm64 images were getting amd64 binaries causing
"exec format error" when running on ARM platforms.
Root cause:
- Dockerfiles had ARG TARGETOS=linux and ARG TARGETARCH=amd64
- FROM --platform=$TARGETOS/$TARGETARCH used these defaults
- buildx couldn't override them, so all builds used amd64
Solution:
- Removed --platform from FROM statement
- Let buildx automatically handle platform selection
- Declared ARGs AFTER FROM to receive buildx values
- buildx automatically sets TARGETPLATFORM, TARGETOS, TARGETARCH
Now each platform builds native binaries:
- linux/amd64 → amd64 binary
- linux/arm64 → arm64 binary
This fixes: exec /usr/local/bin/migrate: exec format error
go.mod requires go >= 1.25.5 but Dockerfiles were using golang:1.23-alpine.
Updated all Go-based Dockerfiles to use golang:1.25-alpine.
Affected files:
- Dockerfile.server
- Dockerfile.scanner
- Dockerfile.migrate
This fixes the build error:
"go: go.mod requires go >= 1.25.5 (running go 1.23.12; GOTOOLCHAIN=local)"
Problem:
- Enabling CGO_ENABLED=1 for SQLite support caused cross-compilation failures
- ARM64 assembly errors when building from amd64 host
- Cross-compilation with CGO requires architecture-specific toolchains
Solution:
- Converted all Dockerfiles to multi-stage builds
- Binaries now compile inside Docker using native platform builders
- Used --platform flag to build for target architecture natively
- Removed binary builds from .goreleaser.yaml (skip: true)
- Updated dockers_v2 to use buildx with multi-platform support
Changes:
- .goreleaser.yaml: Skip standalone builds, use Docker buildx
- Dockerfile.server: Multi-stage build with CGO
- Dockerfile.scanner: Multi-stage build with CGO
- Dockerfile.migrate: Multi-stage build with CGO
Benefits:
- No cross-compilation needed (each platform builds natively)
- Docker buildx handles multi-platform builds automatically
- SQLite support working with CGO enabled
- Cleaner separation between build and runtime environments
Changes:
- Set CGO_ENABLED=1 for gohoarder main binary in .goreleaser.yaml
- Add sqlite-libs and musl to Dockerfile.server
- Add sqlite-libs and musl to Dockerfile.scanner
All Go binaries that interact with SQLite now have CGO enabled:
✅ gohoarder (main binary) - used by server and scanner
✅ migrate (migration tool)
Runtime containers include necessary C libraries:
✅ Dockerfile.server - SQLite runtime support
✅ Dockerfile.scanner - SQLite runtime support
✅ Dockerfile.migrate - SQLite runtime support
This fixes: 'Binary was compiled with CGO_ENABLED=0, go-sqlite3 requires cgo'
