PHP + POSTGRESQL + REDIS in K8s
Challenge
This project shows how to create a setup for a local env with PHP, PGSQL, and REDIS in K8s that could be used for day-to-day development.
It is tested locally, but it can be used also for pipeline like the gitlab-ci, or using your own docker-registry or DigitalOcean / Heroku and tested in the cloud like Azure, AWS EKS...
Working with helm charts/kustomization/docker-compose and recently mostly with GitOps in AWS in an awesome infra with Flux+CrossPlane+SOPS+Traefik+Calico, I'll consider this project a basic project that shows a multi-approach to configure the kube environments.
It is using the normal k8s base64 secrets, but can be configured also with secret-manager/rotation ect..

- How to use the networks and the persistent volumes.
Files / Folders
| WHERE | WHAT | WHY |
|---|---|---|
| /deploy.sh | To run with args start / stop' |
Makes the pods and forward the APP port 8000 to localhost |
| /php/ | Contains the docker build folder with the PHP code APP and the Kube manifests to deploy. |
NGINX Proxy to serve PHP8-PFM |
| /postgresql/ | Contains the Kube POSTGRESQL manifests to deploy. |
Sample employees data to load |
| /redis/ | Contains the Kube REDIS manifests to deploy. |
Basic Redis with AUTH |
Get ready!
The Kube project is composed of 3 components:
1. A PHP-FPM + NGINX as Deployment
2. A Postgres database as StateFulSet.
3. A Redis server as a caching server as Deployment.
The bash script ./deploy.sh will create the ENV to test it locally.
:~# chmod a+x deploy.sh
:~# ./deploy.sh start
-
It builds a PHP8-FPM docker image named 'php' with the APP files, and the necessary libraries to run PostgreSQL and Redis (similar to a pipeline stage).
-
Then the script will deploy the pods (deployments, configmaps, secrets, services)
- You can visit https://localhost:8000 from your browser the result.
Get down!
The bash script ./deploy.sh will shutdown the ENV.
:~# ./deploy.sh stop
Remove Docker images
:~# docker image prune -a
