Summary

Armkit, Azure Cloud Development Kit (CDK), is an open source software development framework to define cloud Infrastructure as Code (IaC) and provision it through Azure ARM Templates.

It offers a high-level object-oriented abstraction to define Azure resources imperatively using the power of modern programming languages. Using the Armkit library of infrastructure constructs, you can easily encapsulate Azure best practices in your infrastructure definition and share it without worrying about boilerplate logic.

Armkit is available in the following languages:

• JavaScript/TypeScript (Node.js ≥ 12.17.0)

Background

Developers use the Armkit framework in one of the supported programming languages to define reusable cloud components called constructs, which are composed together into stacks, forming an "Armkit app".

They then use the Armkit CLI to interact with their Armkit app. The CLI allows developers to synthesize artifacts such as Azure ARM Templates, deploy stacks to development Azure accounts and diff against a deployed stack to understand the impact of a code change.

The Armkit Construct Library includes a module for each Azure service with constructs that offer rich APIs that encapsulate the details of how to use Azure. The Armkit Construct Library aims to reduce the complexity and glue-logic required when integrating various Azure services to achieve your goals on Azure.

Armkit packages:

• @armkit/core - A library that allows users to build Azure applications contructs.
• armkit-resources - A library for defining Azure resources using programming constructs.
• armkit-cli - A CLI that allows users to run commands to initialize, import, and synthesize Armkit applications.

Examples

Some sample constructs are in examples. This could look like this:

helloArmkit.ts

import { Construct } from "constructs";
import { App, ArmStack } from "@yetics/armkit-core";
import {
  ContainerGroups,
  ContainerGroupPropertiesOsType,
  MicrosoftContainerInstanceContainerGroupsType,
  MicrosoftContainerInstanceContainerGroupsApiVersion,
} from "./.generated/ContainerInstance-2021-03-01";
import {
  Registries,
  MicrosoftContainerRegistryRegistriesApiVersion,
  MicrosoftContainerRegistryRegistriesType,
  SkuName,
} from "./.generated/ContainerRegistry-2019-05-01";

export class HelloArmkit extends ArmStack {
  constructor(scope: Construct, id: string) {
    super(scope, id);

    new ContainerGroups(this, "MyContainerGroup", {
      name: "azurecdktest",
      location: "westeurope",
      apiVersion:
        MicrosoftContainerInstanceContainerGroupsApiVersion["2021_03_01"],
      type:
        MicrosoftContainerInstanceContainerGroupsType.MICROSOFT_CONTAINER_INSTANCE_CONTAINER_GROUPS,
      properties: {
        containers: [
          {
            name: "ubuntu-server",
            properties: {
              image: "ubuntu:18.04",
              command: ["sleep infinity"],
              resources: {
                requests: {
                  cpu: 1,
                  memoryInGB: 2,
                },
                limits: {
                  cpu: 1,
                  memoryInGB: 2,
                },
              },
            },
          },
        ],
        osType: ContainerGroupPropertiesOsType.LINUX,
      },
    });

    new Registries(this, "azurecdktest", {
      name: "azurecdktest",
      location: "westeurope",
      apiVersion: MicrosoftContainerRegistryRegistriesApiVersion["2019_05_01"],
      type:
        MicrosoftContainerRegistryRegistriesType.MICROSOFT_CONTAINER_REGISTRY_REGISTRIES,
      sku: {
        name: SkuName.BASIC,
      },
      properties: {
        adminUserEnabled: false,
      },
    });
  }
}

const app = new App({ outdir: "cdk.out" });
new HelloArmkit(app, "hello-armkit");
app.synth();

Building

Clone the project repository

git clone https://github.com/Yetics/armkit.git

Download dependencies and build node.js

cd armkit/
yarn install
yarn build

Build the examples/basic package:

Go to examples/basic:

cd /examples/basic

Generate the armkit cdk libs:

yarn generate

Translate typescript to node.js:

yarn build

Render ARM template from CDK:

node index.js

Check out the results:

az deployment group create --resource-group <resource-group-name> --template-file @cdk-out/helloarmkit.json
