1.22+ck1 Bugfix release

October 21, 2021 - charmed-kubernetes-807

What’s new

• Configurable default PodSecurityPolicy

A new pod-security-policy config option has been added to the kubernetes-master charm. This option allows you to override the default PodSecurityPolicy that is created by the charm.

• Configurable Nvidia APT sources

New config options have been added to the containerd charm: nvidia_apt_key_urls, nvidia_apt_sources, and nvidia_apt_packages. These provide better support for Nvidia GPUs in air gapped deployments by allowing you to specify where the Nvidia Container Runtime and CUDA packages are pulled from.

• Better OpenStack credential handling

The openstack-integrator charm now checks for updated cloud credentials from Juju every time its update-status hook runs, ensuring that cloud credentials are properly detected a short time after they change. To expedite this process, you can use the new openstack-integrator charm’s new refresh-credentials action to force a recheck immediately.

1.22

September 1, 2021 - charmed-kubernetes-761

What’s new

• Calico BGP Service IP Advertisement

The Calico charm now supports advertising Kubernetes service IPs using Border Gateway Protocol (BGP). More information can be found in the CNI with Calico page.

• Improved load balancer provider support

Support for load balancing the Kubernetes control plane is being improved with two new relation endpoints: loadbalancer-external and loadbalancer-internal. This change adds support for Azure native load balancers for the Kubernetes control plane, and improves LB configurability while still simplifying the relations needed between the various components of the cluster.

Component upgrades

• cephcsi 3.3.1 (note: see upstream notes if upgrading from a previous release)
• kube-dns 1.17.3 (note: coredns 1.8.3 is the default DNS provider)
• nginx-ingress 1.0.0-beta.3
• metrics-server 0.5.0

Notes and Known Issues

• LP 1935992 Code cleanup

  Previously deprecated features have been removed in this release. This includes the following kubernetes-master features:

  • addons-registry config
  • create-rbd-pv action and related templates
  • monitoring-storage config
  • kube-dns interface
  • migrate_from_pre_snaps code

  The following deprecated kubernetes-worker features have been removed in this release:

  • allow-privileged config
  • kube-dns interface
  • registry action and related templates

• LP 1907153 Snap install failure in LXD

  Snaps may fail to install when the kubernetes-master charm is deployed to a LXD container. This happens when the version of snapd on the host does not match the version inside the container. As a workaround, ensure the same version of snapd is installed on the host and in LXD containers.
