How to run it?
the only requisit to run it is to have a mailgun account and a s3 bucket with the right permissions. check the .env.example file for setting up the env variables.
to try it locally you can run the following commands:
docker-compose up -d --build
then you can access the service at http://localhost:8000
to run it on kubernetes check the services folder there you will find the kubernetes deployment and service files. so you just have to run the following command:
note you need to have at least 2 nodes in your cluster
kubectl apply -f service/deployment.yaml
kubectl apply -f service/service.yaml
