🛠️ Project 1: Infrastructure Setup

Goal: Provision robust infrastructure, DNS, TLS, and Kubernetes

Example: Provision Hetzner VMs via Terraform

resource "hcloud_server" "worker" { count = 3 name = "worker-${count.index + 1}" server_type = "cx31" image = "ubuntu-22.04" ssh_keys = [hcloud_ssh_key.main.id] user_data = file("init.yaml") }

Automated TLS with cert-manager:

apiVersion: cert-manager.io/v1 kind: ClusterIssuer metadata: name: letsencrypt-prod spec: acme: email: devops@example.com server: https://acme-v02.api.letsencrypt.org/directory privateKeySecretRef: name: letsencrypt-prod solvers: - http01: ingress: class: nginx

---

🚀 Project 2: CI/CD Pipelines

Goal: Git push to production with rollback support

Example: GitHub Actions deploy with Helm

jobs: deploy: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - name: Helm Deploy run: | helm upgrade --install app ./helm \ --namespace production \ --set image.tag=${{ github.sha }}

Secure secrets with SealedSecrets:

apiVersion: bitnami.com/v1alpha1 kind: SealedSecret metadata: name: app-secret spec: encryptedData: password: AgBq...

📊 Project 3: Monitoring and Logs

Goal: Gain full visibility into infrastructure and application health

Prometheus + Grafana via Helm:

helm install monitoring kube-prometheus-stack \ -n monitoring --create-namespace

Grafana dashboard config:

grafana: dashboards: default: nodes: gnetId: 1860 datasource: Prometheus

Loki + Promtail for logs:

promtail: config: clients: - url: http://loki.monitoring.svc:3100/loki/api/v1/push

🔒 Project 4: Security and Access Management

Goal: No shared root access, no plain-text secrets, and always encrypted

RBAC role for developers:

kind: Role metadata: name: dev-readonly rules: - apiGroups: [""] resources: ["pods", "services"] verbs: ["get", "list"]

TLS everywhere: Automated renewals with Let’s Encrypt Secrets: Managed via Vault or SealedSecrets Audit: Access logs and RBAC-based policies
