Simple PHP app

This is a simple PHP application running in a Kubernetes pod. It uses Nginx as the web server and PHP-FPM for processing PHP scripts.

Prerequisites

• kubectl
• minikube

Deployment

1. minikube start --nodes=2
2. minikube image build -t simpleapp:v1 --all=true .
3. kubectl apply -f fpm-config.yaml -f nginx-config.yaml
4. kubectl apply -f deployment.yaml -f service.yaml
5. echo $(minikube ip):32111 | xclip -selection c
6. In your browser paste (ctrl-v) and load the page

* NOTE: The eval $(minikube docker-env) command is used to set the Docker environment variables so that the Docker CLI can communicate with the Minikube Docker daemon. To verify your terminal is using minikube’s docker-env you can check the value of the environment variable MINIKUBE_ACTIVE_DOCKERD to reflect the cluster name. (printenv MINIKUBE_ACTIVE_DOCKERD).

* NOTE 2: You can update your /etc/hosts file and add minikube ip to your custom local domain like <YOUR-MINIKUBE-IP> minikube minikube.local and then request site by the domain e.g.: minikube:32111

* NOTE 3: For multi node (more then one) you need to use minikube registry addon; For minikube 1.36 it will be this command to make the installation successful: minikube addons enable registry --images="KubeRegistryProxy=registry.k8s.io/kube-registry-proxy:0.4,Registry=docker.io/registry:2.8.3"
