Lab: Build Application Components

In this lab we will build Docker containers for each of the application components and setup the back-end database.

Prerequisites

• Clone this repo in Azure Cloud Shell.
• Complete previous labs:
  • AKS

Instructions

1. Create Azure Container Registry (ACR)

   • Use the same resource group that was created for AKS (in lab 1)

   • In this step, you will need a unique name for your ACR instance. Use the following step to create the ACR name and then deploy.

     # Use the UNIQUE_SUFFIX from the first lab. Validate that the value is still set.
     echo $UNIQUE_SUFFIX
     
     export RGNAME=kubernetes-hackfest
     export ACRNAME=acrhackfest$UNIQUE_SUFFIX
     
     az acr create --resource-group $RGNAME --name $ACRNAME --sku Basic
     

2. Run bash script to authenticate with Azure Container Registry from AKS

   • Running this script will grant the Service Principal created at cluster creation time access to ACR.

      sh reg-acr.sh

3. Deploy Cosmos DB

   • In this step, create a Cosmos DB account for the Mongo api. Again, we will create a random, unique name.

     # Use the UNIQUE_SUFFIX from the first lab. Validate that the value is still set.
     echo $UNIQUE_SUFFIX
     
     export RGNAME=kubernetes-hackfest
     export COSMOSNAME=cosmos$UNIQUE_SUFFIX
     
     az cosmosdb create --name $COSMOSNAME --resource-group $RGNAME --kind MongoDB
     

   • You can validate your Cosmos instance in the portal. The credentials and connect string will be used in the next lab.

4. Create Docker containers in ACR

   • In this step we will create a Docker container image for each of our microservices. We will use ACR Builder functionality to build and store these images in the cloud.

     cd ~/kubernetes-hackfest
     
     # the $ACRNAME variable should be set from step 1
     echo $ACRNAME
     
     # set a version (make this anything you would like)
     export VERSION=v4
     
     az acr build -t hackfest/data-api:$VERSION -r $ACRNAME --no-logs ./app/data-api
     az acr build -t hackfest/flights-api:$VERSION -r $ACRNAME --no-logs ./app/flights-api
     az acr build -t hackfest/quakes-api:$VERSION -r $ACRNAME --no-logs ./app/quakes-api
     az acr build -t hackfest/weather-api:$VERSION -r $ACRNAME --no-logs ./app/weather-api
     az acr build -t hackfest/service-tracker-ui:$VERSION -r $ACRNAME --no-logs ./app/service-tracker-ui
     

   • You can see the status of the builds by running the command below.

     az acr build-task list-builds -r $ACRNAME -o table
     
     az acr build-task logs -r $ACRNAME --build-id aa1
     

   • Browse to your ACR instance in the Azure portal and validate that the images are in "Repositories."
