k3d

Compiling

In order to debug k3s it is first necessary to recompile it with debug symbols.

cd k3s
DEBUG=true make

NOTE: currently make support for debug symbols is available on the master branch.

A v1.23.6-rc4+k3s1 fork with the patch is available here: https://github.com/moio/k3s/tree/v1.23.6-rc4+k3s1-dbg

With k3d, you will have to specify the image you just built. Run:

docker images

to get its name and version and then append --image <IMAGE_NAME> to the k3d create commandline.

After creation, find the container name you want to debug:

docker ps

Then debug it with

./util-debugger-k3d.sh <CONTAINER_NAME>
