A Helm chart deployed to AKS that stores TODOs in an Azure Cosmos DB MongoDB API
Stands up an Azure Kubernetes Service (AKS) cluster and a MongoDB-flavored instance of
Azure Cosmos DB. On top of the AKS cluster, we also deploy a Helm Chart with a simple
Node.js TODO app bitnami/node, swapping out the usual in-cluster MongoDB instance
with our managed Cosmos DB instance.
Prerequisites
Install Pulumi.
Install .NET 5
We will be deploying to Azure, so you will need an Azure account. If you do not have an account, sign up for free here.
Setup and authenticate the native Azure provider for Pulumi.
Running the Example
In this example we will provision a Kubernetes cluster running a public Apache web server, verify we can access it, and clean up when done.
Get the code:
$ git clone git@github.com:pulumi/examples.git $ cd examples/azure-cs-aks-cosmos-helmCreate a new stack, which is an isolated deployment target for this example:
$ pulumi stack initSet the required configuration variables for this program:
$ pulumi config set azure-native:location westus2Deploy everything with the
pulumi upcommand. This provisions all the Azure resources necessary, including an Active Directory service principal, AKS cluster, and then deploys the Apache Helm Chart, all in a single gesture (takes 5-10 min):$ pulumi up Type Name Status Info + pulumi:pulumi:Stack azure-cs-aks-cosmos-helm-dev created 1 warning + ├─ kubernetes:helm.sh/v3:Chart node created + │ ├─ kubernetes:core/v1:Service node created + │ └─ kubernetes:apps/v1:Deployment node created + ├─ example:component:CosmosDBMongoDB mongo-todos created + │ ├─ azure-native:documentdb:DatabaseAccount cosmos-mongodb created + │ └─ azure-native:documentdb:MongoDBResourceMongoDBDatabase todos created + ├─ example:component:AksCluster demoaks created + │ ├─ azuread:index:Application app created + │ ├─ random:index:RandomPassword pw created + │ ├─ tls:index:PrivateKey ssh-key created + │ ├─ azuread:index:ServicePrincipal service-principal created + │ ├─ azuread:index:ServicePrincipalPassword sp-password created + │ ├─ azure-native:containerservice:ManagedCluster demoaks created + │ └─ pulumi:providers:kubernetes k8s-provider created + ├─ azure-native:resources:ResourceGroup cosmosrg created + └─ kubernetes:core/v1:Secret mongo-secrets created Outputs: Endpoint: "http://20.73.205.163"Now your database, your cluster, and application are ready. An output variable will be printed to provide the application endpoint.
