Walkthrough

The Dockerfile for the Ubuntu container disk image in the Kubernetes application package was updated to include the installation of the NVIDIA driver package nvidia-dkms-535. This addition is achieved by appending a command to install the driver using apt-get via guestfish --remote, following the installation of Kubernetes components. No changes were made to the declarations of exported or public entities.

Poem

In the Dockerfile, a tweak so neat,
NVIDIA drivers now complete!
With guestfish magic, drivers install,
Kubernetes runs for one and all.
Now GPUs hum in harmony,
Thanks to this container symphony!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (Invoked using PR comments)

There is still some issues with driver load.

It does not work with gpuOperator.valuesOverride.gpu-operator.driver.enabled=false:

Same as with gpuOperator.valuesOverride.gpu-operator.driver.enabled=true:

Also it significantly increases pipeline time, and decreases the user flexibility, so I would keep it as-is for now.
