## Summary
This PR prepares tika-grpc-docker for the future release of Tika 4.0.0 by
implementing GPG signed release verification, aligning with the tika-docker
repository's approach.
## Background
**tika-grpc has not been officially released yet** - it only exists in Tika
4.0.0-SNAPSHOT. This PR prepares the repository to handle both:
- Current development builds (from source)
- Future production builds (from GPG-signed releases)
## Changes
### Added Files
- **republish-images.sh** - Script to rebuild all versions from GPG-signed
Apache releases (ready for when 4.0.0 releases)
### Modified Files
- **README.md** - Major updates:
- Added pre-release status warning at the top
- Documented current build method (`build-from-branch.sh` for development)
- Documented future build method (`docker-tool.sh` with GPG verification)
- Explained relationship between tika repo Maven builds and this repo
- Clarified when to use each build approach
- **minimal/Dockerfile** - Added comment explaining it requires official
Apache releases (Tika 4.0.0+)
- **full/Dockerfile** - Same note as minimal/Dockerfile
## How It Works
### Current State (Pre-Release)
Build from source using:
```bash
./build-from-branch.sh -b main
```
### Future State (Post Tika 4.0.0 Release)
Build from GPG-signed releases:
```bash
./docker-tool.sh build 4.0.0 4.0.0
```
This will:
1. Download `tika-server-grpc-4.0.0.jar` from Apache distribution mirrors
2. Download the `.asc` GPG signature file
3. Import Apache KEYS
4. Verify the GPG signature
5. Build Docker image with verified JAR
## Alignment with tika-docker
This PR ensures tika-grpc-docker follows the EXACT same pattern as
tika-docker:
- ✅ Downloads from Apache mirrors
- ✅ Verifies GPG signatures
- ✅ Multi-stage builds
- ✅ docker-tool.sh for building
- ✅ republish-images.sh for batch rebuilds
- ✅ build-from-branch.sh for development
## Testing
The Dockerfiles already contain the GPG verification logic (inherited from
tika-docker). They will work automatically once `tika-server-grpc-4.0.0.jar` is
published to Apache distribution mirrors.
Development builds can be tested now with:
```bash
./build-from-branch.sh -b main
```
## Related
This complements the work in apache/tika PR #2462 (TIKA-4578) which adds
Maven-based Docker builds to the tika repository for development purposes.
