kata-debug

kata-debug is a tool that is used as part of the Kata Containers CI to gather information from the node, in order to help debugging issues with Kata Containers.

As one can imagine, this can be expanded and used outside of the CI context, and any contribution back to the script is very much welcome.

The resulting container is stored at the Kata Containers quay.io space and can be used as shown below:

kubectl debug $NODE_NAME -it --image=quay.io/kata-containers/kata-debug:latest

Building and publishing

The project can be built and publish by calling the following command from the Kata Containers top directory:

make build-and-publish-kata-debug

Users can specify the following environment variables to the build:

  • KATA_DEBUG_REGISTRY - The container registry to be used default: quay.io/kata-containers/kata-debug
  • KATA_DEBUG_TAG - A tag to the be used for the image default: $(git rev-parse HEAD)-$(uname -a)
