Running the server

Docker compose

You can run the server in docker compose:

version: '2.1'
services:
  app:
    image: aghost7/jokemongo
    environment:
      jokemongo.db.url: 'mongodb://db/jokemongo'
    ports:
      - 8066:8066
  db:
    image: mongo

Kubernetes

This simple app was mainly built so that I can experiment with kubernetes clustering with a stateful app. As a result, its fairly simple to get going. This will be split into two parts: how to get the app running in kubernetes with the least amount of effort and how to get it running with replication.

If you don't already have kubernetes locally, make sure to check out minikube.

Doing it the wrong way

Spin up the cluster:

minikube start
kubectl apply -f k8s/technically-incorrect-deployment.yml

And you can now interact with the app using:

curl $(minikube service jokemongo --url) \
	-d 'What is the motto of people who harvest organs? We de-liver.'

And also:

curl $(minikube service jokemongo --url)

Doing it the right way

Azure

WIP

Requirements:

  • Azure Account
  • Azure CLI of installed

Create the resource group:

az group create --name jokemongo --location canadacentral

Create the kubernetes cluster:

az aks create \
	--resource-group jokemongo \
	--name jokemongo-cluster \
	--node-count 1 \
	--enable-addons monitoring \
	--generate-ssh-keys

Load up the kubectl context:

az aks get-credentials --resource-group jokemongo --name jokemongo-cluster

Create the not-so-secret secret:

kubectl create -f k8s/sample-secret.yml

Create the resources:

kubectl create -f k8s/replicated-deployment.yml
