Kloudfuse can be installed on a shared Kubernetes cluster. Within the shared cluster, it is highly recommended to have a dedicated node group for running Kloudfuse.
Using Node Affinity, Taints and Tolerations to Deploy Kloudfuse on the Dedicated Node Group.
Add Taint to Node Group
Ensure that the nodes have NoSchedule
taint, e.g., dedicated=kfuse:NoSchedule
taint. It is recommended that the taint is configured through the cloud provider, rather than kubectl
. This ensures that the taints are persisted across node restart or replacement.

On EKS, refer to https://docs.aws.amazon.com/eks/latest/userguide/node-taints-managed-node-groups.html .
Add Label to Node Group
Ensure that the nodes have a custom label for Kloudfuse, e.g., dedicated=kfuse
.

Helm Custom Values
Tolerations
In the default values.yaml
, each services Kfuse service has a tolerations
section that is defaulted to []
. Copy and overwrite the tolerations
sections in the custom_values.yaml
. Using the example taint configuration above, add the following in each tolerations section:
Code Block |
---|
tolerations: - key: "dedicated" operator: "Equal" value: "kfuse" effect: "NoSchedule" |
FAQ
Kloudfuse pods are getting scheduled and run on other nodes (not on the nodes dedicated for Kloudfuse).
...
Node Affinity
In the default values.yaml, each Kfuse service has a affinity.nodeAffinity
section. Copy and overwrite the the nodeAffinity
sections in the custom_values.yaml. Using the example label configuration above, add the following in each nodeAffinity section:
