An Introduction to  WordPress on Kubernetes Helm

WordPress is a popular content management system used globally. It has the capability to run websites of different sizes, based on the web traffic as well as the amount of content. Interestingly, deploying WordPress on Kubernetes is another way to horizontally scale a website while effortlessly handling sudden traffic surges.

Helm acts as Kubernetes’s package manager. In other words, it is responsible for packaging, configuring as well as deploying appreciation and services in a Kubernetes cluster.

Furthermore, Helm relies on a packaging format called charts. To put it in simpler terms, a Helm chart can be described as a collection so YAML files describing a related set of Kubernetes resources.

According to our experts, we can set up a WordPress instance on a Kubernetes cluster. This offers a hosting infrastructure that can be scaled easily. Additionally, it offers resilience and flexibility.

How to deploy WordPress on Kubernetes Helm Chart

Today, we are going to take a look at deploying WordPress on Kubernetes with Helm Chart:

1. First, we have to add the repository with the WordPress Helm chart we plan to deploy:

   helm repo add [repositoryname] [repositoryaddress]
2. Next, we have to update Helm repositories with the following command:

   helm repo update
3. After that, we have to install the cart as seen below:

   helm install [releasename] [repositoryaddress] Then we have to wait for the chart to be deployed successfully.
4. Next, we can use minikube to open a new terminal window and enter this command in order to emulate the LoadBalancer:

   minikube tunnel
5. Once the Running status is displayed by minikube, we have to minimize this window and return to the previous one.
6. Then, we will check if the deployment is ready with this command:

   kubectl get all
7. Then, we have to run the following command to export the SERVICE_IP environment variable:

   export SERVICE_IP=$(kubectl get svc --namespace default wp-test-wordpress --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}")
8. Finally, we can display the IP address of the service with the echo command.
9. Once we enter the address in the browser’s address bar, the WordPress installation will start.
