Azure Kubernetes Service

The Azure Kubernetes Service (AKS) enables speedy cluster deployment and management.

Prerequisites

The following applications are pre-installed in the system.

  • Active Azure account. The Azure subscription includes the following resources: storage, compute, networking, and container service.
  • Cygwin, Helm, and Azure CLI.
  • The Kubernetes command-line tool kubectl.

Deployment Artefacts

Holdings Microservices for Azure Kubernetes Service(AKS) deployment is available as a single release bundle (For example, ms-holdings-helm-postgres-pack-XXX.zip).

The images are available in the path ms-holdings-helm-postgres-pack-XXX\images.

The AKS scripts to run and build images are available in the path ms-holdings-helm-postgres-pack-XXX\helm-chart.

Use the script AKS-helm-install.sh/AKS-helm-postgres-install.sh to deploy the AKS. Use the script AKS-helm-uninstall.sh/AKS-helm-postgres-uninstall.sh to stop and remove the setup for AKS.

The setup folder contains all the necessary files that help in the creation of Resource Group AKS Cluster, ACR, Storage account, storage secret, event hub, and event hub topics.

Usage of Setup files

The following is the usage of each file inside the setup folder(ms-holdings-helm-postgres-pack-XXX\helm-chart\Azure-AKS\Setup).
