This is a repo for setting up AKS Namespaces for onboarding in Kubernetes

Goal

• Migrate an Helm Chart to Bicep format to test Bicep extensibility
• Use the Bicepparams experimentatal feature for params, that would replace the values.yaml from Helm
• Use the following new features
  • provider
  • import
  • export
• Export and Import user defined types and functions.

Docs

• Bicep Extensibility - Experminental Feature

• Define Application in Bicep

• AKS Ingress - Web Application Routing

• Bicep Custom Types

bicepconfig.json for preview features

{
  "experimentalFeaturesEnabled": {
    "paramsFiles": true,
    "extensibility": true,
    "symbolicNameCodegen": true,
    "userDefinedTypes": true,
    "resourceTypedParamsAndOutputs": true
  }
}

Bicep Extensibility uses import

• Example to create namespace

@secure()
param kubeConfig string
param nameSpace string

import 'kubernetes@1.0.0' with {
  namespace: 'default'
  kubeConfig: kubeConfig
}

resource coreNamespace 'core/Namespace@v1' = {
  metadata: {
    name: nameSpace
  }
}

Example using bicepparam (replaces json format)

using '../../bicep/main.bicep'

param DeploymentDef = {
  DeploymentId: '2'
  Environment: 'D'
  appName: 'AKS'
  orgName: 'PE'
  prefix: 'AEU1'
}

param DeploymentHubDef ={
  appName: 'HUB'
  orgName: 'PE'
  prefix: 'ACU1'
}

param AKSAppDefs = [
  {
    customDomain: 'aginow.net'
    image: 'mcr.microsoft.com/azuredocs/aks-helloworld:v1'
    nameSpace: 'hello-web-app-routing'
    serviceName: 'aks-helloworld'
    titleMessage: '"Web App Routing ingress" --> Deployed with Azure Bicep'
    clusterName: '01'
    tlsCertName: 'agic01-psthing-com'
  }
]

param VaultName = 'VLT01'

• Example for deploying main.bicep

param (
    [switch]$whatif
)

$Base = $PSScriptRoot
$splat = @{
    Name                  = 'Namespace_Bicep'
    ResourceGroupName     = 'AEU1-PE-AKS-RG-D2'
    TemplateFile          = "$Base\bicep\main.bicep"
    TemplateParameterFile = "$Base\tenants\AKS\values-d2.bicepparam"
}

# requires az.resources 6.6.1 included in AZ 9.7.0
New-AzResourceGroupDeployment @splat -Verbose @PSBoundParameters
