Implementation of the repo on the hardware rke

1) Bootstrapping

• Installation of RKE2 on the admin, dev and prod cluster

• Installation of metalLB by creating a namespace

  1. kubectl create namespace metallb-system

  2. kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.15.2/config/manifests/metallb-native.yaml

• Install argoCD

  1. kubectl create namespace argocd

  2. kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

Create a IP POOL

1. nano metallb-config.yaml

apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:
  name: default-pool
  namespace: metallb-system
spec:
  addresses:
    - 192.168.56.100-192.168.56.120
---
apiVersion: metallb.io/v1beta1
kind: L2Advertisement
metadata:
  name: default
  namespace: metallb-system

Accessing the argocd

ssh -L 8081:192.168.56.100:443 arcade@117.250.206.138

Get the Password of the argocd and then change it later

kubectl -n argocd get secret argocd-initial-admin-secret \-o jsonpath="{.data.password}" | base64 -d && echo

Registering the Cluster by installing the argocd cli

Step1: cpy the Dev Kubeconfig file

scp worker1@192.168.56.11:/etc/rancher/rke2/rke2.yaml ~/dev.yaml

Step2: cpy the prod Kubeconfig file

scp worker2@192.168.56.12:/etc/rancher/rke2/rke2.yaml ~/prod.yaml

step3: Change the API SERVER

nano ~/dev.yaml

Replace this

server: https://127.0.0.1:6443

With this

server: https://192.168.56.11:6443

Confirm with this

kubectl --kubeconfig=/home/master/dev.yaml get nodes

Same way for the prod cluster

scp worker2@192.168.56.12:/etc/rancher/rke2/rke2.yaml ~/prod.yaml

Edit the API SERVER

nano ~/prod.yaml

REplcae the API SERVRE

server: https://192.168.56.12:6443

TEst it

kubectl --kubeconfig=/home/master/prod.yaml get nodes

Login To ARGOCD

argocd login 192.168.56.100 --insecure

master@mastervm:~$ argocd login 192.168.56.100 --insecure
Username: admin  
Password: 
'admin:login' logged in successfully
Context '192.168.56.100' updated
master@mastervm:~$ 

Enter the password tht u changed after u logged in using UI

Add the cluster

Dev cluster

argocd cluster add --kubeconfig /home/master/dev.yaml default

Prod cluster

argocd cluster add --kubeconfig /home/master/prod.yaml default

List the clusters

argocd cluster list

⚠️ Warning: THe cluster names will be default which u can rename from the UI or u can rename by rm the clusters and renaming and then joining(Search Internet for mre info).
