---

1. build web api app from command line

   • dotnet restore
   • dotnet build
   • dotnet publish -o published

2. build docker image locally

   • docker build -t {YOUR-DOCKER-ID}/the-app .

3. run docker image + mongodb locally

   • docker run -d -p 27017:27017 --name mongodb bitnami/mongodb:latest
   • docker run -d -p 80:80 --name webapi --link mongodb {YOUR-DOCKER-ID}/the-app

4. push app container to Docker Hub

   • docker login
   • docker push {YOUR-DOCKER-ID}/the-app

5. use Azure CLI to connect to ACS cluster

   • az login
   • az account set --subscription "{YOUR-AZURE-SUBSCRIPTION-ID}"
   • az acs kubernetes get-credentials --resource-group="{YOUR-ACS-RG-NAME}" --name="{YOUR-KUBE-ACS-NAME}"

6. push mongo service

   • kubectl apply -f mongo.service.yaml

7. push mongo deployment

   • update mongo.deployment.yaml
   • kubectl apply -f mongo.deployment.yaml

8. push app service

   • kubectl apply -f app.service.yaml

9. push app deployment

   • update app.deployment.yaml
   • kubectl apply -f app.deployment.yaml

10. admin UI

    • kubectl proxy
    • localhost:8001/ui
