Deployment of a persisted mongodb replica set and a golang api in kubernetes

An example project demonstrating the deployment of a mongodb replica set and a Golang API in Kubernetes. Minikube is used to run k8s locally. kubectl is used to deploy the mongodb replica set. helm is used to deploy the golang API.

1 - Deploy the mongodb replica set

Follow the mongodb readme

2 - Deploy the golang API

Follow the api readme

3 - Test the API

First of all, let's get the API service URL out of minikube.

$ minikube service  person-api --url

Use the outputted URL in your internet browser (e.g.: http://192.168.99.100:31518). You should see Welcome to the person API! displayed

Get persons out of the person API. The expected output is a HTTP status 200 OK and a [] of persons.

$ curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X GET http://192.168.99.100:31518/persons

Now, let's insert our first person. The expected output is a HTTP status 201 Created.

$ curl -i -H "Accept: application/json" -H "Content-Type: application/json" -d '{"first_name":"ray", "last_name":"masson"}'  -X POST http://192.168.99.100:31518/persons

Run again the first curl command. The output should now be something like [{"id":"5ab505c424e8f10001f047b5","first_name":"ray","last_name":"masson"}]
