Utho Kubernetes Cluster (UKC) Service Expose to Loadbalancer

Deploy Nginx as Node Port

kubectl apply -f https://raw.githubusercontent.com/uthoplatforms/examples/main/nginx-deployment-service.yaml

kubectl get services -o wide

Deploy Loadbalancer via API or via Utho Console Add backend to Loadbalancer by selecting Kubernetes Nodepool or Mannual External IP Address of worker nodes with nodeport as backend port.

Utho Kubernetes Cluster (UKC) Storage Classes

openebs (default)

This is the default storage class, providing read-write once access to applications on storage. If the application does not specify a storage class in the PersistentVolumeClaim (PVC), this storage class will be automatically assigned.

To use this storage class, apply the following YAML:

kubectl apply -f https://raw.githubusercontent.com/uthoplatforms/examples/main/pod-with-default-sc-pvc.yaml

openebs-hostpath (Local PV)

This storage class is based on local hostpath storage, offering read-write once permission on storage. It is suitable when the worker node count is always one.

To use this storage class, apply the following YAML:

kubectl apply -f https://raw.githubusercontent.com/uthoplatforms/examples/main/pod-with-hostpath-sc-pvc.yaml

openebs-nfs (NFS PV)

This storage class is NFS-based, providing read/write access to storage. It should be used when applications need to use shared storage.

To use this storage class, apply the following YAML:

kubectl apply -f https://raw.githubusercontent.com/uthoplatforms/examples/main/pod-with-nfs-sc-pvc.yaml

For dynamic provisioning of storage class, applications need to create Persistent Volume Claims (PVCs) to obtain persistent volume (storage) in the cluster. Based on application requirements, storage can be selected, and if the application does not define a storage class in the PVC, the default storage class (openebs(default)) will be assigned automatically.

Utho Kubernetes Cluster (UKC) Load Balancer

Step 1

Deploy Loadbalancer via API or via Utho Console

Step 2

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.10.0/deploy/static/provider/cloud/deploy.yaml

Step 3 ( this step will nginx service to use given public ip and service will not be in pending mode)
