For Kublr Kubernetes clusters deployed on vSphere, you may encounter an update error that requires manual unmounting of CD/DVD drive 1 from each virtual machine using the vCenter console.
Elasticsearch is only supported on the AMD64 architecture. If you are using an ARM64 cluster, you can use tag 7.17.9 for the cluster nodes. Refer to the following link for more information: Use Elasticsearch v7.16.3 or Above.
vSphere CSI limitation: Please refer to the VMWare documentation for information on vSphere functionality supported by the vSphere Container Storage Plug-in.
CRI change limitation: When deploying an Ingress controller in hostPort mode (typically for vSphere or BareMetal installations), DNAT rules may not be cleaned properly. This is an open issue in the Felix project. If your Ingress NGINX controller connection times out, please reboot the worker nodes.
SUSE SLES 12 sp5 can’t be run with ContainerD CRI (Docker is end of support in Kuberntes v1.24.0). Kublr can’t find the correct way for automatically installing containerd-ctr utilities, but fully supports Kubernetes installation with preinstalled ContainerD CRI and containerd-ctr utilities.
Google Cloud Platform SUSE SLES 15 sp4 can’t use the Google Cloud Engine CSI PD driver. The root cause is the relocation of /lib/udev to /var/lib/udev on the root file system. Please use custom CSI drivers installation and disable Kublr CSI support via the cluster spec:
