31-33: LGTM! Consistent implementation of security contexts across all components.The addition of security contexts at both container and pod levels follows Kubernetes best practices and is implemented consistently across all components (base, frontend, meta, datanode, and flownode).
Consider documenting the recommended security context values in the chart's values.yaml file to guide users in setting appropriate security configurations.

87-262: Consider adding security context examples.While the security context configuration options are well documented, it would be helpful to add example configurations to demonstrate recommended security settings for production deployments.
Consider adding examples like:
| base.podTemplate.main.securityContext | object | `{}` | The configurations for security context of main container. | +For example: +```yaml +securityContext: + runAsNonRoot: true + runAsUser: 1000 + readOnlyRootFilesystem: true +```

58-60: Verify pod-level security context propagation.
The pod-level security contexts (podTemplate.securityContext) should be verified to ensure they are properly propagated to the pods.

✅ Verification successful
Security context configuration is properly implemented
The verification shows that security contexts are correctly implemented at both pod and container levels:
- Container-level security contexts (*.podTemplate.main.securityContext) are properly propagated to individual containers with correct indentation
- Pod-level security contexts (*.podTemplate.securityContext) are correctly set at the pod spec level
- The implementation is consistent across all components (frontend, meta, datanode, flownode)
- Default empty security contexts ({}) are provided in values.yaml, allowing users to override with custom configurations

17-17: Verify compatibility with the new initializer version
The initializer version has been updated from v0.1.3-alpha.3 to v0.1.3-alpha.6. Since this is an alpha version, please ensure:
- The new version is compatible with the current GreptimeDB version (
v0.9.5) - The changes between alpha.3 and alpha.6 have been tested in a staging environment
✅ Verification successful
Let me gather more information about version compatibility by checking the chart dependencies and requirements.
Based on the gathered information, I can now generate the final response:
Version update appears safe to proceed
The initializer version bump from v0.1.3-alpha.3 to v0.1.3-alpha.6 aligns with the chart's appVersion (v0.9.5). The changes are minor (within the same alpha series) and the operator chart is being updated in parallel, suggesting coordinated testing by the maintainers. No explicit version constraints or compatibility issues were found in the chart configuration.
