Description: Deploy an example workload into an existing kubernetes cluster.
Metadata:
  cfn-lint: { config: { ignore_checks: [W9002, W9003, W9004, W9006, E9008] } }
Parameters:
  KubeClusterName:
    Type: String
Resources:
  # This resource creates a ConfigMap in the target cluster. It retrieves and decrypts a kms encrypted
  # kubernetes config file, which is automatically created when customers deploy an EKS cluster with the Quick Start.
  # For bring-your-own-cluster, the customer must encrypt and upload a config file prior to launching the stack.
  #
  # The "URL" property is an exact representation of a regular kubernetes resource manifest, available by link.
  KubeManifestURLExample:
    Type: AWSQS::Kubernetes::Resource
    Properties:
      ClusterName: !Ref KubeClusterName
      Namespace: my-ns
      # Kubernetes manifest URL
      Url: https://k8s.io/examples/controllers/nginx-deployment.yaml
  # This resource creates a ConfigMap in the target cluster. It retrieves and decrypts a kms encrypted
  # kubernetes config file, which is automatically created when customers deploy an EKS cluster with the quickstart,
  # for bring-your-own-cluster the customer must encrypt and upload a config file prior to launching the stack.
  #
  # The "Manifest" property is an exact representation of a regular kubernetes resource manifest, on stack create
  # `kubectl create --save-config` is called, on stack update `kubectl apply` and on stack delete `kubectl delete`
  #
  # The following elements are available to be used in other cloudformation resources using !GetAtt:
  # ResourceVersion, SelfLink, Uid
  KubeManifestExample:
    Type: AWSQS::Kubernetes::Resource
    Properties:
      ClusterName: !Ref KubeClusterName
      Namespace: kube-system
      # Kubernetes manifest
      Manifest: !Sub |
        apiVersion: v1
        kind: ConfigMap
        metadata:
          name: test
        data:
          # examples of consuming outputs of the HelmExample resource below's output. Creates an implicit dependency, so
          # this resource will only launch once the HelmExample resource has completed successfully
          GrafanaId: ${HelmExample}
  # This resource deploys the kubernetes service catalog from it's helm chart.
  #
  # using !GetAtt you can fetch Name (release name) and Namespace, as well as all of the created resources, who's keys
  # are the resource type + an index for the case where a chart creates more than 1 of a Kind (eg. ConfigMap0 fetches
  # the 1st ConfigMap created)
  HelmExample:
    Type: AWSQS::Kubernetes::Helm
    Properties:
      ClusterID: !Ref KubeClusterName
      # Namespace is optional. In most cases it's best to leave this out so
      # that a namespace is dynamically generated. If namespace does not exist
      # it will be created.
      #
      # Namespace: example-ns
      #
      Chart: grafana/grafana
      Repository: https://grafana.github.io/helm-charts
      #
      # Name can be specified, if not helm will generate one.
      # Name: myRelease
      # If Version isn't specified, latest will be used.
      # Version: 1.0.1
      # Custom values can optionally be specified.
      Values:
        testFramework.enabled: true
        imagePullPolicy: Always
      # If there are a lot of values, or they contain ambiguous types (eg, enable: "true" or count: "1") then values can
      # be passed as yaml enclosed in a string literal
      # ValueYaml: |
      #   deep:
      #     nested:
      #       list:

      #         - "1"
Outputs:
  # Examples for using the outputs of the KubeManifestExample resource
