Introduction

This is a Java Spring Boot micro service application which exposes a REST API against an in memory MognoDB instance. Intended to be deployed to Azure Kubernetes Services this application is design to demonstrate the features for the Java Applications Insights Codeless jar file.

Getting Started

To use this application you will need to do the following

• Required software
  • Docker desktop
  • kubectl which will be installed with Docker Desktop
  • Azure CLI
• Generate a SAS token from the Azure container blob which has the private preview jar file.
• Update the docker file on line 10 to point to the newly created url including SAS token.
• Deploy an Azure Kubernetes Service to a subscription that you have access to. See: https://docs.microsoft.com/en-us/azure/aks/kubernetes-walkthrough-portal#create-an-aks-cluster
• Get admin credentials from AKS
• Create an Azure Container Registry
• Ensure you can push and pull images to your new ACR. See: https://docs.microsoft.com/en-us/azure/container-registry/container-registry-get-started-docker-cli?tabs=azure-cli
• Grant your AKS cluster access to pull images from your ACR. See: https://docs.microsoft.com/en-us/azure/aks/cluster-container-registry-integration
• Do a docker build in the same directory as the docker file.
• Tag the newly created docker image with the appropriate name from your ACR
  • Example: docker tag cf2afeb88816 dracr.azurecr.io/cosmos-demo:latest
• Push the image
• Update jfr-deploy.yml file with the correct docker image name.
• If everything worked you should be able to do a kubectl apply -f ./jfr-deploy.yml and have a working site.

Example Commands I used

az acr create --name DrAcr --resource-group aks-westus --sku Standard az aks update --name draks --resource-group aks-westus --attach-acr DrAcr az aks check-acr --name draks --resource-group aks-westus --acr DrAcr.azurecr.io az acr update --admin-enabled true --name dracr az acr login --name dracr

before building the docker image you need to generate a sas token for the jar file

Docker build . docker tag cf2afeb88816 dracr.azurecr.io/cosmos-demo:latest docker push dracr.azurecr.io/cosmos-demo:latest
