Description
Install Fedora CoreOS and debug kernel crashes using kdump as described in documentation.
Setup
- Download and verify the latest FCOS next image (pick the right image for your environment).
How to test
- Create an Ignition file. When writing the configuration, add a
crashkernel=300M
section following the example in the documentation. You don't necessarily have to use the same kernel arguments from the documentation, but you can. - Launch your Fedora CoreOS system using this Ignition file. See the Quickstart and the provisioning docs for a guide how to launch FCOS in most environments (bare metal, virtual, cloud, etc).
