For Upgrading Existing Nodes

Pre-Installation Steps: Install K3s

1. Install K3s:

Run the following command in your terminal to install K3s. This step will automatically download and install K3s while disabling unnecessary components:

curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC="--disable=traefik" sh -s -

2.Configure kubeconfig:

Configure access for the kubectl command-line tool:

mkdir ~/.kube
sudo cat /etc/rancher/k3s/k3s.yaml | tee ~/.kube/config >/dev/null

3.Verify K3s Installation:

After installation, use the following command to confirm that K3s is installed and running correctly:

kubectl get nodes

4.Install Helm:

Helm is a tool for managing Kubernetes applications. Install Helm with the following commands:

wget https://get.helm.sh/helm-v3.11.0-linux-amd64.tar.gz
tar -zxvf helm-v3.11.0-linux-amd64.tar.gz
install linux-amd64/helm /usr/local/bin/helm

5.Install Ingress Nginx:

Use Helm to install Ingress Nginx, which adds HTTP routing rules for applications:

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm upgrade --install ingress-nginx ingress-nginx \
  --repo https://kubernetes.github.io/ingress-nginx \
  --namespace ingress-nginx --create-namespace

6.Use Mounted Disk /mnt/storage:

• Remove the default local-path StorageClass label:

kubectl patch storageclass local-path -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'

• Create and set a new storage class as default:

Create a storageclass.yaml file and include the following content:

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: local-storage
  annotations:
    storageclass.kubernetes.io/is-default-class: "true"
provisioner: rancher.io/local-path
volumeBindingMode: WaitForFirstConsumer
reclaimPolicy: Delete
parameters:
  path: "/mnt/storage"

Apply the StorageClass to the K3s cluster:

kubectl apply -f storageclass.yaml

Update the ConfigMap path to /mnt/storage:

kubectl patch configmap local-path-config -n kube-system --type=json -p='[{"op": "replace", "path": "/data/config.json", "value":"{\n  \"nodePathMap\":[\n  {\n    \"node\":\"DEFAULT_PATH_FOR_NON_LISTED_NODES\",\n    \"paths\":[\"/mnt/storage\"]\n  }\n  ]\n}"}]'

For Upgrading Existing Nodes

1. Remove the old version

Remove the old version before downloading the new version.
