revelc33 / somesome Goto Github PK

The original exercise was proposed with Ansible. However, I suggested doing it with Kubernetes/Docker.

To facilitate testing, I also added the option to deploy it locally using Docker, but both options are available:

• Docker run
• Kubernetes manifests

To deploy the solution, you just need to execute a single command (in a Linux environment with Docker or Kubernetes available).

git clone https://github.com/revelc33/somesome.git && cd somesome/scripts && bash launcher.sh

The main deployment file is a script (launcher.sh) that initiates a menu that basically calls one of the chosen deployment options:

• Docker (dockerDeploy/main.sh):
  • This option requires Docker to be installed locally, and the user must have permissions to run Docker. Of course, the Docker service must also be running.
• Kubernetes (kubernetesDeploy/main.sh):
  • This option requires kubectl and envsubst to be installed.

If you prefer to deploy manually, you can follow these steps:

git clone https://github.com/revelc33/somesome.git && cd somesome

cd frontend
sudo docker build -t maquema/frontend:hoy .
sudo docker run -p 81:8000 -e BACKEND_DOMAIN=localhost -t maquema/frontend:hoy &

cd ../backend
sudo docker build -t maquema/backend:hoy .
sudo docker run -p 80:5001 -e SERVICE_CLOCK_PORT=5001 -t maquema/backend:hoy &

To test the application, open your browser and enter http://127.0.0.1:81

(The goal of this test is to deploy a simple "clock" web application (frontend + backend) in a container machine using Docker.)

|-- backend/        (Clock service sources (Python/Flask), Dockerfile, and Kubernetes manifests.)
|   |-- src/
|   |   |-- [backend service source code]
|   |-- Dockerfile
|   |-- backend.yaml (Kubernetes manifest)
|
|-- frontend/       (Frontend sources , Dockerfile, and Kubernetes manifests.)
|   |-- src/
|   |   |-- [frontend service source code]
|   |-- Dockerfile
|   |-- frontend.yaml (Kubernetes manifest)
|
|-- scripts/        (Script for deploying locally in Docker with Docker run.)
|   |-- build-docker-and-deploy.sh (script to build Docker image and deploy locally)
|   |-- deploy-kubernetes.sh (script to deploy in Kubernetes)
|   |-- launcher.sh  (The main script for full deployment.)

|-- README.md (project documentation)

Kubernetes Deployment (requires 'kubectl' pointing to the correct Kubernetes cluster and envsubst tool instlled) (tested in EKS and Minikube).

• Run frontend and backend services using Docker (DONE)
• Configure the backend application using environment variables (DONE)
• Don't run services as root (DONE)
• Configure and deploy EVERYTHING using a single command, i.e., a bash script (DONE)
