Notes / Known Issues

  • Secret names

LP 1906732 highlighted an issue where kubernetes-worker units would overwrite existing secrets when deployed as different application names. This lead to some worker units losing the ability to authenticate with the cluster. This has be resolved by ensuring new secrets are uniquely named in the form: auth-$username-$random.

  • Juju and GCP

LP 1761838 describes an issue with Juju and Google cloud where deployments may fail due to FAN networking. Workaround this by disabling FAN configuration for Google cloud models:

juju model-config -m <model_name> fan-config="" container-networking-method=""

What’s new

  • Calico VXLAN support

The Calico charm now supports enabling VXLAN encapsulation for Calico network traffic. This provides an easier alternative to the direct routing or IPIP encapsulation modes, making it possible to run Calico on any Juju cloud without special cloud configuration. For more details, see the [Calico CNI documentation page][cni-calico].

  • CoreDNS operator charm support

The CoreDNS component can now be deployed as an operator charm inside the Kubernetes cluster instead of being managed by the cdk-addons snap. This allows for more control over the component, including additional configuration options and easier contribution of bug fixes or upgrades to that component.

Details on how to set this up can be found in the CoreDNS section of the Addons page.

  • Kubernetes Dashboard operator charm support

The Kubernetes Dashboard component can now be deployed as an operator charm inside the Kubernetes cluster instead of being managed by the cdk-addons snap. This allows for more control over the component, including additional configuration options and easier contribution of bug fixes or upgrades to that component.

Details on how to set this up can be found in the Kubernetes Dashboard section of the Addons page.
