Generating a Kata Containers payload for the Confidential Containers Operator

Confidential Containers Operator consumes a Kata Containers payload, generated from the CCv0 branch, and here one can find all the necessary info on how to build such a payload.

Requirements

  • make installed in the machine
  • Docker installed in the machine
  • sudo access to the machine

Process

  • Clone Kata Containers 
    git clone --branch CCv0 https://github.com/kata-containers/kata-containers
    • In case you've already cloned the repo, make sure to switch to the CCv0 branch 
      git checkout CCv0
    • Ensure your tree is clean and in sync with upstream CCv0 
      git clean -xfd
git reset --hard <upstream>/CCv0
  • Make sure you're authenticated to quay.io 
    sudo docker login quay.io
  • From the top repo directory, run: 
    sudo make cc-payload
  • Make sure the image was upload to the Confidential Containers runtime-payload registry

Notes

Make sure to run it on a machine that's not the one you're hacking on, prepare a cup of tea, and get back to it an hour later (at least).
