```bash
kubectl krew install oadp
```
#### Via krew manifest (for testing or custom indexes)
```bash
curl -LO https://github.com/migtools/oadp-cli/releases/download/${{ github.ref_name }}/kubectl-oadp.yaml
kubectl krew install --manifest=kubectl-oadp.yaml
```
#### Manual installation
1. Download the appropriate binary for your platform
2. Extract the archive
3. Add the binary to your PATH
4. Verify installation: `kubectl oadp --help`
### Supported Platforms
- Linux (amd64, arm64)
- macOS (amd64, arm64)
- Windows (amd64, arm64)
### Files Included
- **Binary archives**: Platform-specific kubectl-oadp binaries with LICENSE
- **checksums.txt**: SHA256 checksums for all binaries
- **kubectl-oadp.yaml**: Final krew plugin manifest with populated SHA256 values
### For Krew Index Maintainers
The `kubectl-oadp.yaml` file contains the complete krew plugin manifest with all SHA256 checksums populated and can be used directly for krew index submissions.
