Install ArgoCD on Minikube on an Ubuntu

Step 1:Install Minikube

minikube is local Kubernetes, focusing on making it easy to learn and develop for Kubernetes.

All you need is Docker (or similarly compatible) container or a Virtual Machine environment

Install Docker

sudo apt-get update
sudo apt-get install docker.io -y
sudo usermod -aG docker $USER #my case is ubuntu
systemctl restart docker

To download latest minikube setup refer minikube official download page

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

Install Minikube on Ubuntu

sudo install minikube-linux-amd64 /usr/local/bin/minikube && rm minikube-linux-amd64

To check minikube version on Ubuntu

minikube version

Output:

Step 2:Install kubectl

The Kubernetes command-line tool, kubectl, allows you to run commands against Kubernetes clusters. You can use kubectl to deploy applications, inspect and manage cluster resources, and view logs

Download kubectl binary with curl on Ubuntu using below command

 curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

Install kubectl

sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

To check kubectl version on Ubuntu

kubectl version --client --output=yaml

Output:

Step 3:Start MiniKube on Ubuntu

Start the minikube Kubernetes cluster on Ubuntu

minikube start

output:

To Check the status of Minikube

minikube status

Output:

minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured

Step 4:Install ArgoCD on Minikube

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes.

Just like other Kubernetes tools, ArgoCD requires a namespace with its name. Therefore, we will create a namespace for argocd.

kubectl create ns argocd

ArgoCD can be installed using its manifests. First, you’ll need to download these manifests and apply them to your Minikube cluster.

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

This will create the necessary resources for ArgoCD within the argocd namespace.

Let’s verify the installation by getting all the objects in the ArgoCD namespace.

kubectl get all -n argocd

Output:

Step 5:Access ArgoCD UI on Browser

By default, the ArgoCD server is not exposed outside the cluster. You can expose it using port-forwarding to access the ArgoCD UI.

kubectl port-forward svc/argocd-server -n argocd --address 0.0.0.0 8080:443

The ArgoCD UI will be available at http://localhost/IP:8080. Access it through your web browser.

Now we can go to a browser and open instance_ip:8080

You will see a privacy warning. Just ignore the warning, click on Advanced and then hit on Proceed to localhost (unsafe) to continue to the GUI interface. (Your browser setting may present a different option to continue).

Get the initial password for the admin user to log in

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

Use the generated password to log in as the admin user in the ArgoCD UI.

Successfully installed ArgoCD on minikube.
