WordPress Example

This example is based on the official Kubernetes WordPress tutorial.

Instructions

Generate the Kubernetes architecture diagram for WordPress manifests:

$ kube-diagrams -o wordpress *.yaml

Start a minikube cluster:

$ minikube start --memory 5120 --cpus=4

Deploy the WordPress application:

$ 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:

$ kubectl get all,sa,cm,secret,pvc,pv,sc -o=yaml > namespace_default.yml

Generate a Kubernetes architecture diagram for the default namespace:

$ kube-diagrams namespace_default.yml

Generate a Kubernetes architecture diagram for the default namespace but hide ReplicaSet objects:

$ kube-diagrams -c hide_replicaset.kd -o namespace_default_without_replicaset.png namespace_default.yml

Delete the WordPress application:

$ 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.

$ kube-diagrams -c custom_diagram.kd -o wordpress_deployed_in_aws_eks namespace_default.yml
