Deploying WordPress in Amazon EKS with RDS in Backend

WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database.

Let’s begin with configuring EKS cluster

select the appropriate Cluster Service Role or create a new one

the endpoint should be public so that we can access the site.

Create the cluster and wait till it becomes active. Now we need to add a Node group to this cluster, where the pods will be launched

In the Node IAM role this policy have to be attached ->

AmazonEKSWorkerNodePolicy

AmazonEC2ContainerRegistryReadOnly

AmazonEKS_CNI_Policy

select the instance type as needed

select the minimum and max nodes to be present in case the load keeps varying

wait for the node-group to get ready

now connect to the cluster by ->

aws eks --region <region-code> update-kubeconfig --name <cluster-name>

It is necessary to be using the aws commands with same user that created the cluster.

Let’s create a deployment with the wordpress image ->

kubectl create deployment <name> --image=<image-name>

Let’s scale the deployment to 2 replicas ->

kubectl scale deployment <name> --replicas=<number>

Now we see two pods running

Expose port no. 80 so that client and the database can connect to pod

CREATING THE DATABASE WITH AWS RDS

Let’s use MySQL database

Wait till the database is Available

connect to mysql server and create the database on it

Now open the wordpress webui and enter the details as required, when everything is correct then this page will appear

After successful login this page appears, now we can use WordPress!
