Overview

Gitops template for Open Policy Agent policies development.

This template will:

• Create a local K8s cluster, using k3d.

  • Install ArgoCD.

    • Install ELK stack for monitoring

    • Install Open Policy Agent Gatekeeper and deploy the first policy.

make targets step by step:

1. validate_code: Run github-linter locally and validate code (docker container)

2. prepare_cluster: Install all necessary packages and create a K3d cluster

3. install_argocd: Install ArgoCD and all the argocd applications (OPA, ELK, etc.).

4. port_forward_argocd: Access argocd in localhost:8080

After deployment you will have a K3d cluster with an active ArgoCD installation, Open Policy Agent Gatekeeper and ELK stack for logs and metrics.

To access ArgoCD:

• Check CLI output for ArgoCD UI password.

• In your browser ==> localhost:8080

To access Kibana:

• In a new terminal: kubectl port-forward deployment/kibana-kibana 5601 -n monitoring

• In your browser ==> localhost:5601

In Management ==> Kibana ==> Index patterns, create the index pattern using the 2 available indexes.

Check Logs and Metrics for available data, add filters to Discover for data filtering.
