Deploy WordPress in Kubernetes.
Deploying WordPress on Kubernetes requires creating several resources, including Deployments, Services, Persistent-Volume-Claims, and MySQL database.
Accessing the Kubernetes Master Node
To access the master node in a Kubernetes cluster, follow these LINK:
Open a terminal session.
Use the SSH protocol to connect:
Replace
user
with your username andmaster-node-address
with the IP address or hostname of the master node.Enter your password or authenticate with your SSH key when prompted.
Once connected, you can perform administrative tasks on the Kubernetes master node.
Create WordPress Directory
To initiate the process of setting up WordPress, begin by creating a directory for WordPress files:
Open your terminal or command prompt and access the Kubernetes master node by SSH and kubeconfig-file.
Navigate to the Kubernetes Master node where you want to store your WordPress files.
Run the following command to create a new directory in the Kubernetes master node:
This command creates a new folder named wordpress
where you can proceed with the installation and configuration of your WordPress site.
Then navigate to the WordPress directory:
To set up a web application using Kubernetes, you'll need to deploy both MySQL and WordPress. This setup involves creating three primary configuration files: a deployment file for MySQL, a PersistentVolumeClaim (PVC) for ensuring the database storage persists, and a deployment file for WordPress. Each component plays a critical role in ensuring your application is resilient, scalable, and has reliable storage.
WordPress Deployment YAML (wordpress-deployment.yaml
):
vi wordpress-deployment.yaml
Ensure you replace placeholder values like your_db_user
, your_db_password
, your_db_name
, and your_mysql_root_password
with appropriate values for your setup.
MySQL Deployment YAML (mysql-deployment.yaml
):
vi mysql-deployment.yaml
Ensure you replace placeholder values like your_db_user
, your_db_password
, your_db_name
, and your_mysql_root_password
with appropriate values for your setup.
PersistentVolumeClaim YAML (persistent-volume-claim.yaml
):
vi persistent-volume-claim.yaml
You can apply these YAML files to your Kubernetes cluster using the kubectl apply -f
command. For example:
kubectl apply -f wordpress-deployment.yaml
kubectl apply -f mysql-deployment.yaml
kubectl apply -f persistent-volume-claim.yaml
Ensure you replace placeholder values like your_db_user
, your_db_password
, your_db_name
, and your_mysql_root_password
with appropriate values for your setup.
This configuration sets up WordPress with a MySQL database backend and a LoadBalancer service for external access to WordPress. Adjustments may be necessary depending on your specific requirements and environment.
