Explanation about the project14:55
This is project 1. WordPress Deployment & Service
• Deployment
o Runs a single WordPress instance (replicas: 1).
o Uses the latest WordPress Docker image.
o Connects to the MariaDB database (db) for data storage.
o Reads database credentials from a Kubernetes Secret (db-secret).
o Uses a PersistentVolumeClaim (wb-pvc) for wp-content, ensuring data persistence.
• Service
o Exposes WordPress via a NodePort service on port 30080.
o Allows external access to WordPress through http://<NodeIP>:30080.
2. phpMyAdmin Deployment & Service
• Deployment
o Runs a single phpMyAdmin instance (replicas: 1).
o Connects to the MariaDB database (db) for database management.
o Uses db-secret for MYSQL_ROOT_PASSWORD.
• Service
o Exposes phpMyAdmin via a NodePort service on port 30081.
o Allows external access through http://<NodeIP>:30081.
3. MariaDB (Database) Deployment & Service
• Deployment
o Runs a single MariaDB instance (replicas: 1).
o Stores database credentials (MYSQL_ROOT_PASSWORD, MYSQL_USER, MYSQL_PASSWORD, MYSQL_DATABASE) in a Kubernetes Secret (db-secret).
o Uses a PersistentVolumeClaim (db-pvc) to store MySQL data at /var/lib/mysql, ensuring data persistence.
• Service
o Provides an internal ClusterIP service to allow WordPress and phpMyAdmin to connect on port 3306.
Dependency Flow
1. WordPress → Connects to MariaDB (db) using environment variables from db-secret.
2. phpMyAdmin → Connects to MariaDB (db) for database management.
3. MariaDB (db) → Stores WordPress data and user credentials.
4. Persistent Volumes (wb-pvc, db-pvc) → Ensure that WordPress media content and database data persist even if pods restart.
