Sync Options

Common Sync Options

PrunePropagationPolicy=foreground - Wait for pruned resources to be deleted
CreateNamespace=true - Auto-create namespace
Validate=false - Skip kubectl validation
PruneLast=true - Prune resources after sync
RespectIgnoreDifferences=true - Honor ignore differences
ApplyOutOfSyncOnly=true - Only apply out-of-sync resources

Best Practices

Use automated sync for non-production
Require manual approval for production
Configure sync windows for maintenance
Implement health checks for custom resources
Use selective sync for large applications
Configure appropriate retry policies
Monitor sync failures with alerts
Use prune with caution in production
Test sync policies in staging
Document sync behavior for teams
