# WordPress Example
|
|
|
|
This example is based on the **[official Kubernetes WordPress tutorial](https://kubernetes.io/docs/tutorials/stateful-application/mysql-wordpress-persistent-volume/)**.
|
|
|
|
## Instructions
|
|
|
|
Generate the Kubernetes architecture diagram for WordPress manifests:
|
|
```sh
|
|
$ kube-diagrams -o wordpress *.yaml
|
|
```
|
|
|
|
Start a minikube cluster:
|
|
```sh
|
|
$ minikube start --memory 5120 --cpus=4
|
|
```
|
|
|
|
Deploy the WordPress application:
|
|
```sh
|
|
$ kubectl apply -f mysql-pass.yaml
|
|
$ kubectl apply -f mysql-deployment.yaml
|
|
$ kubectl apply -f wordpress-deployment.yaml
|
|
```
|
|
|
|
Wait a few minutes for the WordPress application to be deployed.
|
|
|
|
Get all Kubernetes resources in the `default` namespace:
|
|
```sh
|
|
$ kubectl get all,sa,cm,secret,pvc,pv,sc -o=yaml > namespace_default.yml
|
|
```
|
|
|
|
Generate a Kubernetes architecture diagram for the `default` namespace:
|
|
```sh
|
|
$ kube-diagrams namespace_default.yml
|
|
```
|
|
|
|
Generate a Kubernetes architecture diagram for the `default` namespace but hide ReplicaSet objects:
|
|
```sh
|
|
$ kube-diagrams -c hide_replicaset.kd -o namespace_default_without_replicaset.png namespace_default.yml
|
|
```
|
|
|
|
Delete the WordPress application:
|
|
```sh
|
|
$ kubectl delete -f wordpress-deployment.yaml
|
|
$ kubectl delete -f mysql-deployment.yaml
|
|
$ kubectl delete -f mysql-pass.yaml
|
|
```
|
|
Generate a custom diagram where the WordPress application is deployed in AWS EKS.
|
|
```sh
|
|
$ kube-diagrams -c custom_diagram.kd -o wordpress_deployed_in_aws_eks namespace_default.yml
|
|
```
|
|
|
