This project focuses on deploying and managing stateful and stateless applications within a Kubernetes cluster. Starting from basic setups, it evolved into a production-grade system architecture—demonstrating practical skills and deep understanding of Kubernetes core concepts.
Practical Implementation Highlights
- Stateful Application Management – MySQL via StatefulSet Deployed MySQL using a StatefulSet to maintain stable network identity.
Ensured dedicated PersistentVolumeClaim (PVC) for safe and persistent storage.
Refactored from an initial Deployment setup to avoid data corruption risks.
- Automated Database Initialization – Job + ConfigMap Used a Kubernetes Job for one-time schema setup.
Managed the SQL script with a ConfigMap, ensuring schema readiness before app connection.
- Cluster-Wide Monitoring – Prometheus Node Exporter via DaemonSet Deployed a DaemonSet to run Prometheus Node Exporter on each cluster node.
Enabled real-time, node-level metrics collection.
Everything I have stated here is included in this Project, this is all you need to get started with K8s
| Component | Role |
|---|---|
Pod |
Base execution unit – represents application processes. |
Deployment |
Manages stateless app replicas with rolling updates and scaling. |
Service |
Provides a stable endpoint for app access inside the cluster. |
StatefulSet |
Manages MySQL with stable identity and persistent storage. |
DaemonSet |
Ensures monitoring agent runs on every node. |
Job |
Handles one-time database schema setup. |
CronJob |
Understood for periodic job execution. |
Ingress |
Understood for routing external HTTP/HTTPS traffic to services. |
| Component | Role |
|---|---|
ConfigMap |
Stores config like SQL init script. |
Secret |
Secures sensitive data like MYSQL_ROOT_PASSWORD. |
PersistentVolume (PV) |
Provides storage for the cluster. |
PersistentVolumeClaim (PVC) |
Requests and binds storage to a StatefulSet. |
| Component | Role |
|---|---|
Namespace |
Creates virtual clusters to isolate project components. |
ServiceAccount |
Pod identity for Kubernetes API interactions. |
Role / ClusterRole |
Namespace-scoped vs cluster-wide permissions. |
RoleBinding / ClusterRoleBinding |
Grants permissions from roles to users or services. |
