Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It synchronizes application definitions from a Git repository, ensuring that the desired state of applications is maintained across clusters. Designed for high scalability and automation, Argo CD supports multi-cluster deployments, automated rollbacks, and advanced RBAC policies. This makes it ideal for managing complex Kubernetes environments with precision and reliability.

Before you start

To complete the actions presented below, you must have:

A Scaleway account logged into the console
Owner status or IAM permissions allowing you to perform actions in the intended Organization
A valid API key
Created a Scaleway Kubernetes Kapsule or Kosmos cluster

Deploying the Argo CD application using Easy Deploy

Important

When configuring your Kubernetes cluster, note that certain applications and services, such as Argo CD, may result in additional resources being provisioned. For example, your YAML configuration might create Block Storage volumes or Load Balancers, which could incur extra costs.

In the Scaleway console, navigate to the Kubernetes section under Containers.
Click the name of the cluster where you wish to deploy Argo CD. The Cluster Information tab will display.
Click the Easy Deploy tab. The application dashboard displays.
Click Deploy Application. The application deployment wizard displays.
Choose Application Library to see the list of available applications.
Select the Argo CD application.
Tip
If you cannot find Argo CD on the first page, use the search bar or navigate through the library.
Optionally, customize the default configuration for Argo CD using Helm Charts. If you do not need any customized configuration you can skip this step.
Enter a name (e.g. argocd) and a Kubernetes namespace for your application. If no name is entered, Argo CD will be installed in the default namespace of the cluster.
Click Deploy Application to deploy Argo CD on your Kubernetes cluster.

Retrieving the Argo CD admin password

Access the Kubernetes Dashboard of your cluster and navigate to Secrets under the Config and Storage section.
Click argocd-initial-admin-secret to display the application metadata information.
Click the “eye” icon next to password to reveal the Argo CD admin password. Copy the password.

Connecting to Argo CD

Argo CD uses a LoadBalancer to manage traffic. To check the deployment status, run:

$ kubectl get svc
NAME                               TYPE           CLUSTER-IP      EXTERNAL-IP      PORT(S)                      AGE
argocd-applicationset-controller   ClusterIP      10.39.101.19    <none>           7000/TCP                     5m40s
argocd-dex-server                  ClusterIP      10.36.208.223   <none>           5556/TCP,5557/TCP            5m40s
argocd-redis                       ClusterIP      10.34.58.107    <none>           6379/TCP                     5m40s
argocd-repo-server                 ClusterIP      10.35.236.175   <none>           8081/TCP                     5m40s
argocd-server                      LoadBalancer   10.39.250.191   195.154.xx.yyy   80:30372/TCP,443:32468/TCP   5m40s
kubernetes                         ClusterIP      10.32.0.1       <none>           443/TCP                      55m

Once the external IP status changes from <PENDING> to the assigned external IP, your Argo CD application is up. Copy the IP address and paste it into a web browser. The Argo CD login screen will appear.

Logging into Argo CD

Paste the external IP address of the LoadBalancer service into your web browser to open the Argo CD login screen.
Enter admin as the username and the password retrieved in the previous step to log in.
