Lab 3.x - Ubuntu 24LTS and Calico issues and fixes

gclair

Ran into some issues in getting the services to stay up while running under Ubuntu 24.xLTS on bare metal. Fix was to create an /etc/containerd/config.toml with containerd config default | sudo tee /etc/containerd/config.toml and update it to have the setting SystemdCgroup = true

For Calico I needed to add, under the containers: -> env: subsection a new addition of
- name: IP_AUTODETECTION_METHOD
value: cidr=mymainsubnet/24

There are other options for the AUTODETECTION method where one of them is you can give it an interface.

Once that was done and applied, calico came up great and I could reach Endpoints from the right places in the cluster.
