Using Argo CD

Creating Kubernetes resources using kubectl apply -f can be inefficient. As a developer, managing resources based on code stored in Git enhances control and traceability. APL integrates with Argo CD to provide a seamless GitOps experience, streamlining your deployment process.

Create Kubernetes resources with Argo CD

Start by navigating to the apps section in the APL console, where you will find an app named Argo CD. Click on it to proceed.

Argo CD App in APL Console

In Argo CD, notice that an application specific to your team has already been set up. This application syncs with any manifest present in the Gitea repository designated for your team.

Argo CD Team Application Overview

After clicking on the app and selecting APP DETAILS, you'll find the REPO URL.

Return to the APL console, select the Gitea app in the apps section. In Gitea you will see a repository titled otomi/team-<name>-argocd.

Let's demonstrate the capabilities of Argo CD by adding some manifests to the repository:

  1. Create a file named deploy-nginx.yaml in the repository.

  2. Insert the following contents into the file:

    apiVersion: apps/v1
    kind: Deployment
    metadata:
    name: nginx
    labels:
    otomi.io/app: nginx
    app: nginx
    spec:
    replicas: 1
    selector:
    matchLabels:
    app: nginx
    template:
    metadata:
    labels:
    app: nginx
    spec:
    containers:
    - name: nginx
    image: nginxinc/nginx-unprivileged:stable
    resources:
    limits:
    memory: '128Mi'
    cpu: '200m'
    requests:
    memory: '64Mi'
    cpu: '100m'
    ports:
    - containerPort: 8080
    ---
    apiVersion: v1
    kind: Service
    metadata:
    name: nginx
    spec:
    selector:
    app: nginx
    ports:
    - port: 80
    targetPort: 8080
  3. Commit the changes to the repository.

Once you return to the Argo CD application, click on the team<name> application.

The application is configured for automatic syncing, so a manual SYNC is not needed.
