Installing WordPress on OVHcloud Managed Kubernetes

Find out how to install WordPress on OVHcloud Managed Kubernetes

Last updated April 14th, 2020.

In this tutorial we are going to guide you with the install of Wordpress on your OVHcloud Managed Kubernetes Service.

Before you begin

This tutorial presupposes that you already have a working OVHcloud Managed Kubernetes cluster, and some basic knowledge of how to operate it. If you want to know more on those topics, please look at the OVHcloud Managed Kubernetes Service Quickstart.

You also need to have Helm installer on your workstation and your cluster, please refer to the How to install Helm on OVHcloud Managed Kubernetes Service tutorial.

Installing the Wordpress Helm chart

For this tutorial we are using the Wordpress Helm chart found on Bitnami repository. The chart is fully configurable, but here we are using the default configuration, with only the minimal set of customization to make it work well on OVHcloud Managed Kubernetes Service.

Customizing your install

Maybe you would like your username to be different, or be able to set your password, or choose an external database instead of deploying the MariaDB container...

In order to customize your install, without having to leave the simplicity of using helm and the Wordpress helm chart, you can simply set some of the configurable parameters of the WordPress chart. Then you can add it to your helm install with the --set option (--set param1=value1,param2=value2)

helm install my-first-k8s-wordpress bitnami/wordpress --set allowOverrideNone=true

This will install the needed elements (a MariaDB pod for the database, a Wordpress pod for the webserver with the Worpdress PHP code), allocate the persistent volumes and initialize the services. And at the end, it will give you the connection parameters for your new Wordpress:

$ helm install my-first-k8s-wordpress bitnami/wordpress --set allowOverrideNone=true
NAME: my-first-k8s-wordpress
LAST DEPLOYED: Tue Apr 14 15:14:57 2020
NAMESPACE: default
STATUS: deployed
** Please be patient while the chart is being deployed **

To access your WordPress site from outside the cluster follow the steps below:

1. Get the WordPress URL by running these commands:

  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
        Watch the status with: 'kubectl get svc --namespace default -w my-first-k8s-wordpress'

   export SERVICE_IP=$(kubectl get svc --namespace default my-first-k8s-wordpress --template "{{ range (index .status.loadBalancer.ingress 0
) }}{{.}}{{ end }}")
   echo "WordPress URL: http://$SERVICE_IP/"
   echo "WordPress Admin URL: http://$SERVICE_IP/admin"

2. Open a browser and access WordPress using the obtained URL.

3. Login with the following credentials below to see your blog:

  echo Username: user
  echo Password: $(kubectl get secret --namespace default my-first-k8s-wordpress -o jsonpath="{.data.wordpress-password}" | base64 --decode)

As the instructions say, you will need to wait a few moments to get the LoadBalancer URL. You can test if the LoadBalancer is ready using:

kubectl get svc --namespace default -w my-first-k8s-wordpress

After some minutes, you will get the LoadBalancer URL:

$ kubectl get svc --namespace default -w my-first-k8s-wordpress
NAME                     TYPE           CLUSTER-IP    EXTERNAL-IP     PORT(S)                      AGE
my-first-k8s-wordpress   LoadBalancer   <pending>      80:32296/TCP,443:31838/TCP   2m13s
my-first-k8s-wordpress   LoadBalancer   80:32296/TCP,443:31838/TCP   2m13s

Then you can follow the instructions to get the Admin URL:

$ export SERVICE_IP=$(kubectl get svc --namespace default my-first-k8s-wordpress --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}")
$ echo "WordPress URL: http://$SERVICE_IP/"
WordPress URL:
$ echo "WordPress Admin URL: http://$SERVICE_IP/admin"
WordPress Admin URL:

And putting the URL in your browser will take you to the new blog:

Installing Wordpress

You also use the instructions given by the helm install to get the default username and password for your blog.

In my case:

$ echo Username: user
Username: user
$ echo Password: $(kubectl get secret --namespace default mollified-lynx-wordpress -o jsonpath="{.data.wordpress-password}" | base64 --decode)
Password: 0pdfhdfhfe5

Installing Wordpress

You have a working Wordpress on your OVHcloud Managed Kubernetes Service, congratulations!

Cleaning up

To clean up your cluster, simply use Helm to delete your Wordpress blog.

helm delete my-first-wordpress

It will delete your Wordpress and its associated resources from your cluster:

$ helm delete my-first-wordpress
release "my-first-wordpress" uninstalled
