Deploy Nginx and Phpfpm on Kubernetes Kodekloud


Question: The Nautilus Application Development team is planning to deploy one of the php-based application on Kubernetes cluster. As per discussion with DevOps team they have decided to use nginx and phpfpm. Additionally, they shared some custom configuration requirements. Below you can find more details. Please complete the task as per requirements mentioned below:

1) Create a service to expose this app, the service type must be NodePort, nodePort should be 30012.

2.) Create a config map nginx-config for nginx.conf as we want to add some custom settings for nginx.conf.

a) Change default port 80 to 8091 in nginx.conf.

b) Change default document root /usr/share/nginx to /var/www/html in nginx.conf.

c) Update directory index to index index.html index.htm index.php in nginx.conf.

3.) Create a pod named nginx-phpfpm .

b) Create a shared volume shared-files that will be used by both containers (nginx and phpfpm) also it should be a emptyDir volume.

c) Map the ConfigMap we declared above as a volume for nginx container. Name the volume as nginx-config-volume, mount path should be /etc/nginx/nginx.conf and subPath should be nginx.conf

d) Nginx container should be named as nginx-container and it should use nginx:latest image. PhpFPM container should be named as php-fpm-container and it should use php:7.3-fpm image.

e) The shared volume shared-files should be mounted at /var/www/html location in both containers. Copy /opt/index.php from jump host to the nginx document root inside nginx container, once done you can access the app using App button on the top bar.

Before clicking on finish button always make sure to check if all pods are in running state.

You can use any labels as per your choice.

Note: The kubectl utility on jump_host has been configured to work with the kubernetes cluster.


At first create the configmap according to question

vi configmap.yml

apiVersion: v1
kind: ConfigMap
name: nginx-config
nginx.conf: |
events {}
http {
server {
listen 8091;
index index.html index.htm index.php;
root /var/www/html;
location ~ \.php$ {
include fastcgi_params;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

 Then create the pod

 vi pod.yml

apiVersion: v1
kind: Pod
name: nginx-phpfpm
app: nginx-phpfpm
tier: back-end
- name: shared-files
emptyDir: {}
- name: nginx-config-volume
name: nginx-config
- name: nginx-container
image: nginx:latest
- name: shared-files
mountPath: /var/www/html
- name: nginx-config-volume
mountPath: /etc/nginx/nginx.conf
subPath: nginx.conf
- name: php-fpm-container
image: php:7.3-fpm
- name: shared-files
mountPath: /var/www/html

 Finally create the service

 vi service.yml

apiVersion: v1
kind: Service
name: nginx-phpfpm
type: NodePort
app: nginx-phpfpm
tier: back-end
- port: 8091
targetPort: 8091
nodePort: 30012

 Then apply all configuration

 kubectl apply -f .

 Check the pod

 kubectl get po

 If the pod is running then copy the index.php to nginx-container

 kubectl cp /opt/index.php nginx-phpfpm:/var/www/html/ --container=nginx-container

Then Click on the App Button which is  top right side side of the terminal. If the app is running then the task is done.
