Platform9 CLI

The pf9ctl release 1.33 is now available (release notes for pf9ctl v1.33) and can be installed by running the following command

Bash

bash <(curl -sL https://pmkft-assets.s3-us-west-1.amazonaws.com/pf9ctl_setup)

Bug Fixes

Fixed To resolve the request of using etcdutl instead of the deprecated etcdctl for restoring ETCD, which serves as the datastore for Kubernetes clusters, PMK now bundles the etcdutl binary alongside etcdctl since the upstream open source etcd project recommends etcdutl for snapshot restore operations going forward.

Fixed Decommissioning a node did not remove the proxy configuration file from /etc/systemd/system/containerd.service.d/00-pf9-proxy.conf. This file prevented the host from being re-added to a cluster. Users were advised to remove the file manually to resolve the issue.

Fixed When the internal package repository returned HTTP 403 errors through the proxy, pf9ctl prep-node failed to install required packages and crashed with a segmentation fault.

Fixed After an ETCD backup, reattaching a master node to the cluster failed. Detached nodes remained stuck in a prolonged converging state and did not reach the ready state required for successful reattachment.

Fixed Onboarding a node with pf9ctl 1.30 to a tenant on v5.11.0 with Kubernetes 1.30 connected the node to the Management Plane but left the projectId in QbertDB as NULL, which caused the node to appear in all tenants instead of being assigned to the correct one.

Fixed In PMK versions 5.12.0 and 5.12.1, vouch failed to create new tokens and roles during redeployment when existing vouch data was present in Consul. The system incorrectly skipped creating new entries if previous entries existed, which caused deployment and node onboarding failures.

Known Issues

Known Issue All existing and new AWS clusters in PMK must be configured with an is_updateflag and restricted security group rules. Without this cluster updates(such as AMI updated) and upgrades may fail. Please reach out to Platform9 support for this configuration.

Known Issue During upgrade of a PMK cluster, uninstallation of pf9-kube package may be incomplete/ stuck, if there are any workloads whose associated containers cannot be cleanly stopped and removed. Contact platform9 support if this is observed.

Known Issue On Rocky Linux 9 (tested on 9.2 and 9.4), platform9's pf9-kube package installs iptables-services as a dependency. With recent updates to the upstream repositories, installation will fail due to a missing dependency on iptables-legacy-* packages.

Known Issue (On Rocky Linux 9) Users will need to install the legacy packages by running dnf install iptables or dnf install iptables-utils on workload cluster nodes. Since this is a recent upstream change, a solution will be provided in upcoming releases by packaging the required packages along with pf9-kube package.

Known Issue AWS clusters using flannel CNI need to be updated to use port 2379 instead of 4001 from1.22 version onwards. Workaround is to go to the "Edit cluster" option on the UI and clicked on "Update cluster" without making any changes. This adds the 2379 ingress rule to the master ELB.

Known Issue When a detach operation is performed on a master node in a multi master cluster, it takes approximately 30 minutes to complete all the detach operations and perform cleanup on the node. Therefore, if you want to reattach this node to any other cluster, you need to wait for the nodelet to stop all the phases and perform cleanup before attempting to reattach the node.

Known Issue In some scenarios, after a node is removed from the qbert clusters, nodelet fails to cleanup the data. Workaround is to check and remove the /var/opt/pf9/kube directory if present, even after the node is deauthorized.

Known Issue Cluster upgrade attempt is blocked on UI post a cluster upgrade failure due to nodes being in a converging/not converged state.

Known Issue Kubelet authorization mode is marked set to AlwaysAllow instead of Webhook.

Known Issue PMK Cloud provider created directly in Sunpike cannot be used to create qbert clusters. Qbert cloud providers will work to create both qbert and sunpike clusters. But cloud providers created directly in sunpike CANNOT be used to create qbert clusters. Please use the appropriate one based on your needs.

PMK 5.13.1 Release Highlights (Released 2025-07-28)

Bug Fixes

Fixed Added a Qbert API to update the CNI network plugin and container CIDR post CNI migration. Previously, after successful CNI migration, the console continued to display Calico as the CNI despite Cilium being active, resulting in misaligned visibility of the active networking backend for users and administrators.
