9-20: Consider enhancing migration process safety.The current migration implementation could benefit from additional safety measures:
- No atomic transaction handling - if a migration fails mid-way, the system could be left in an inconsistent state
- Missing rollback mechanism
- Limited logging for debugging purposes
Consider implementing these improvements:
- Add a backup mechanism before running migrations
- Implement rollback functionality
- Enhanced logging with timestamps and status details
- Add a dry-run mode for testing migrations
Would you like me to provide a detailed implementation for these improvements?
Line range hint
14-19: Improve error handling in migration loop.The current migration loop lacks robust error handling:
- No timeout protection against infinite loops
- Missing explicit error handling for kubectl commands
- No validation of migration success
Consider applying this improvement:
current_version=$(kubectl get configmap -n cozy-system cozystack-version -o jsonpath='{.data.version}') || true + start_time=$(date +%s) until [ "$current_version" = "$VERSION" ]; do + # Add timeout after 30 minutes + current_time=$(date +%s) + if [ $((current_time - start_time)) -gt 1800 ]; then + echo "Error: Migration timeout after 30 minutes" + exit 1 + fi echo "run migration: $current_version --> $VERSION" - scripts/migrations/$current_version + if ! scripts/migrations/$current_version; then + echo "Error: Migration $current_version failed" + exit 1 + fi current_version=$(kubectl get configmap -n cozy-system cozystack-version -o jsonpath='{.data.version}') + if [ -z "$current_version" ]; then + echo "Error: Failed to get current version after migration" + exit 1 + fi done

1-3: LGTM! Clear script purpose declaration.The shebang and comment clearly indicate this is a migration script from version 5 to 6.
1-15: Verify the migration's idempotency.The script should be idempotent to handle potential reruns safely.
Let's verify the current version and existing labels:
✅ Verification successful
Let me analyze the migration script for idempotency without relying on
kubectlcommands, as they're not available in the sandbox environment.Looking at the script's operations:
The first part (
kubectl get secret ... | while read ...) applies labels to PVCs and DVs:
- Uses
--overwriteflag for labels, making it safe to rerun- Temporary files are properly cleaned up with
rm -fThe second part creates/updates the version configmap:
- Uses
kubectl apply -f-which is idempotent by design- The version is set to a fixed value of 6
The migration script is safely idempotent
The script is idempotent because:
- Label operations use
--overwriteflag which safely updates existing labels- ConfigMap creation uses
kubectl applywhich is idempotent by design- Temporary files are properly cleaned up
- No destructive operations are performed that could cause issues on reruns
🏁 Scripts executed
The following scripts were executed for the analysis:

Add error handling for version update.
The version update command should verify success.

Add error handling and safety measures.
While the core logic is correct, the script could benefit from additional error handling and safety measures:
- Missing error handling for kubectl commands
- No validation of base64 decoded content
- Temporary file could persist if script fails between creation and cleanup
Consider applying these improvements:

💡 Codebase verification
Migration script 5 exists but is not executable
The migration script for version 5 exists at scripts/migrations/5 but lacks executable permissions (shown as -rw-r--r--), while all previous migration scripts (1-4) are properly executable. This will cause the migration process to fail since the installer script attempts to execute these files directly.
scripts/migrations/5needs executable permissions to be set usingchmod +x
🔗 Analysis chain
Verify migration script existence.
The version bump from 5 to 6 requires a corresponding migration script at scripts/migrations/5 to handle the transition.
Let me try to gather more information about the migration scripts in the repository to ensure we're looking at the correct path.
Let me check one more thing to specifically look for migration scripts in any numbered directories, as the installer.sh suggests they should exist with version numbers.
🏁 Scripts executed
The following scripts were executed for the analysis:
