Deploy Apache

1. Review PHP/Apache deployment YAML

Inspect the YAML file ~/workshop/k3s/php-apache.yaml and validate the contents using the following command:

cat ~/workshop/k3s/php-apache.yaml

This file contains the configuration for the PHP/Apache deployment and will create a new StatefulSet with a single replica of the PHP/Apache image.

A stateless application does not care which network it is using, and it does not need permanent storage. Examples of stateless apps may include web servers such as Apache, Nginx, or Tomcat.

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: php-apache
spec:
  updateStrategy:
    type: RollingUpdate
  selector:
    matchLabels:
      run: php-apache
  serviceName: "php-apache-svc"
  replicas: 1
  template:
    metadata:
      labels:
        run: php-apache
    spec:
      containers:
      - name: php-apache
        image: ghcr.io/splunk/php-apache:latest
        ports:
        - containerPort: 80
        resources:
          limits:
            cpu: "8"
            memory: "8Mi"
          requests:
            cpu: "6"
            memory: "4Mi"

apiVersion: v1

    run: php-apache

2. Deploy PHP/Apache

Create an apache namespace then deploy the PHP/Apache application to the cluster.

Create the apache namespace:

kubectl create namespace apache

Deploy the PHP/Apache application:

kubectl apply -f ~/workshop/k3s/php-apache.yaml -n apache

Ensure the deployment has been created:

kubectl get statefulset -n apache
Workshop Question

What metrics for your Apache instance are being reported in the Apache web servers (OTel) Navigator?

Workshop Question

Using Log Observer what is the issue with the PHP/Apache deployment?

Tip: Adjust your filters to use: k8s.namespace.name = apache and k8s.cluster.name = <your_cluster>.
