Infrastructure as Code - Demo

Deploy Infrastructure-as-Code with Terraform and Ansible.
(GCP Infra, Kubernetes Cluster, CI/CD, Monitoring)

The Big Picture

Applying successfully all manifests will create:

• 5 VMs on GCP (2 controllers, 2 workers, 1 for Nagios Server).
• A Kubernetes Cluster with HA, on 2 controllers and 2 workers.
• Monitoring setup with Nagios, Prometheus/Grafana, Kubernetes Dashboard and KubeOpsView.
• Continuous Integration setup with Jenkins.
• Continuous Deployment setup with ArgoCD.

Specific parts of the Infra, instead of all, can by deployed using the Ansible flags in the manifests.

Requirements

The following should be installed and configured in the host from which the manifests will run:

• Ansible (with kubernetes module)
• gcloud CLI (connected to the GCP project)
• cfssl (for creating kubernets licenses/keys)
• kubectl (will be auto-configured to access the created cluster, after the successful deployment of cluster)

Steps:

1. Deploy Infrastructure on GCP with Terraform.
2. Deploy the Kubernetes Cluster with Ansible.
3. Deploy Monitoring Setup with Ansible.
4. Deploy CI/CD Setup with Ansible.
