TODO API with Kubernetes

Just a study of how to deploy a Kubernetes cluster locally.

First of all:

• To run the tests:
  • requirements:
    • Python ^3.8
    • Poetry

poetry shell
poetry install
pytest

How to deploy it? (locally)

• Requirements:

  • Docker
  • minikube
  • kubectl

• Steps:

  1. Clone this repo and navigate to the root project folder todoapi-k8s.

  2. Start the cluster by running:

     minikube start
     

  3. To point your shell to minikube’s docker-daemon, run:

     eval $(minikube -p minikube docker-env)
     

     That way we can use our local docker images, without having to pull them from the docker hub:

  4. Now build the image in the Dockerfile:

     docker build . -t test-k8s/todoapp
     

  5. Apply a configuration to a resource by file name for pods generation:

     kubectl apply -f deployment.yml
     

  6. Finally run the following commands to list your application's pods and services:

     kubectl get pods
     kubectl get svc
     

     The following command will display the URL where your application is running, copy it and access it in your browser at the /docs endpoint:

     minikube service list
     

     Now you can interact with the API!

NOTE: We are using only one replica of the application because SQLite is being used

To view the logs, run the following command passing the name of your pod:

kubectl logs <name-of-the-pod-here>
