  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit tests.

testing/Dockerfile (1)

• 3-3: The update of the Ceph tag from v14.2.6 to v14.2.22 is a good practice to ensure the use of a more recent and potentially more secure version of Ceph. However, it's important to verify compatibility with existing systems and dependencies.

Ensure that this version of Ceph is compatible with the rest of the system and any dependencies. Testing should be conducted to confirm that no new issues are introduced by this update.

README.md (1)

• 50-50: Directing users to OperatorHub for installation simplifies the process and is a good practice. Ensure that the operator listing on OperatorHub is up-to-date with the latest changes and versions.

Verify that the operator listing on OperatorHub is current and reflects the latest changes and versions.
