s3_api

Flask app who list bucket contents when hitting the / endpoint.

Contents

• terraform folder: Holds the code to create an S3 bucket. (Default name: super-duper-crazy-bucket)
• docker folder: Holds the app.
• k8s folder: Holds the config to deploy the app to k8s.

How to build the infra

cd terraform
terraform init
terraform plan
terraform apply

How to run the container locally

cd docker
docker build -t api .
docker run -p 5000:5000 -d -e AWS_ACCESS_KEY_ID="<Your_Access_Key>" -e AWS_SECRET_ACCESS_KEY="<Your_Secret_Key>" -e BUCKET="<Your_Bucket_Name>" api
curl localhost:5000/

Deployment to k8s

First you need to update the deployment.yml with the BUCKET name of choice (Default: super-duper-crazy-bucket)

The deployment expects the k8s secrets accesskey and secretkey to be present in the cluster, so please have them created before deploying the app:

kubectl create secret generic accesskey --from-literal=AWS_ACCESS_KEY_ID=<Your_Access_Key>
kubectl create secret generic secretkey --from-literal=AWS_SECRET_ACCESS_KEY=<Your_Secret_Key>

Then you can apply the changes:

cd k8s
kubectl apply -f deployment.yml

Now you should expose the container, this will create a service and expose the container's port (5000) to the outside: kubectl expose deployment s3-api-deployment --type=LoadBalancer --port=5000

You can now check that the service is running: Minikube: minikube service s3-api-deployment will open a browser with the bucket name and contents or a "Not Found" if the bucket name is invalid.
