Kubernetes

Docker

Build the images and spin up the containers:

docker-compose up -d --build

Run the migrations and seed the database:

docker-compose exec server python manage.py recreate_db
docker-compose exec server python manage.py seed_db

Test it out at:

1. http://localhost:8080/
2. http://localhost:5001/books/ping
3. http://localhost:5001/books

Créer le deployement:

kubectl create -f ./kubernetes/flask-deployment.yml

Créer le service:

kubectl create -f ./kubernetes/flask-service.yml

Appliquer la migration et la source de la database:

kubectl get pods
kubectl exec flask-<POD_IDENTIFIER> --stdin --tty -- python manage.py recreate_db
kubectl exec flask-<POD_IDENTIFIER> --stdin --tty -- python manage.py seed_db

Vue

Construire l'image et la pousser sur le Docker Hub:

docker build -t <DOCKER_HUB_USERNAME>/vue-kubernetes ./services/client \
    -f ./services/client/Dockerfile-minikube

docker push <DOCKER_HUB_USERNAME>/vue-kubernetes

Again, replace <DOCKER_HUB_USERNAME> with your Docker Hub namespace in the above commands as well as in kubernetes/vue-deployment.yml
