Task control options

All tasks have control options in addition to their task inputs. For more information, see Control options and common task properties.

Output variables

This task defines the following output variables, which you can consume in downstream steps, jobs, and stages.

KubectlOutput
Stores the output of the kubectl command.

Remarks

What's new in Version 1.0.

  • Added a new service connection type input for easy selection of Azure AKS clusters.
  • Replaced the output variable input with an output variables section that we added in all tasks.

Use this task to deploy, configure, or update a Kubernetes cluster by running kubectl commands.

Service connection

The task works with two service connection types: Azure Resource Manager and Kubernetes Service Connection, described below.

Azure Resource Manager

Set connectionType to Azure Resource Manager and specify an azureSubscriptionEndpoint to use an Azure Resource Manager service connection.

This YAML example shows how Azure Resource Manager is used to refer to the Kubernetes cluster. This is to be used with one of the kubectl commands and the appropriate values required by the command.

variables:
  azureSubscriptionEndpoint: Contoso
  azureContainerRegistry: contoso.azurecr.io
  azureResourceGroup: Contoso
  kubernetesCluster: Contoso
  useClusterAdmin: false

steps:
- task: Kubernetes@1
  displayName: kubectl apply
  inputs:
    connectionType: Azure Resource Manager
    azureSubscriptionEndpoint: $(azureSubscriptionEndpoint)
    azureResourceGroup: $(azureResourceGroup)
    kubernetesCluster: $(kubernetesCluster)
    useClusterAdmin: $(useClusterAdmin)

Kubernetes Service Connection

Set connectionType to Kubernetes Service Connection and specify a kubernetesServiceEndpoint to use a Kubernetes service connection.

This YAML example shows how a Kubernetes Service Connection is used to refer to the Kubernetes cluster. This is to be used with one of the kubectl commands and the appropriate values required by the command.

- task: Kubernetes@1
  displayName: kubectl apply
  inputs:
    connectionType: Kubernetes Service Connection
    kubernetesServiceEndpoint: Contoso

Kubernetes Service Connection considerations when accessing AKS

You can create a Kubernetes service connection with any of the following options.

  • KubeConfig
  • Service Account
  • Azure Subscription

Screenshot of choosing a Kubernetes service connection authentication method.

When selecting the Azure Subscription option, Kubernetes needs to be accessible to Azure DevOps at service connection configuration time. There may be various reasons a service connection cannot be created, for example you created a private cluster or the cluster has local accounts disabled. In these cases, Azure DevOps can't connect to your cluster at service connection configuration time and you'll see a stuck Loading namespaces screen.

Screenshot of choosing a Kubernetes service connection authentication dialog stuck at loading namespaces.

Starting with Kubernetes 1.24, long-lived tokens are no longer created by default. Kubernetes recommends not using long-lived tokens. As a result, tasks using a Kubernetes service connection created with the Azure Subscription option don't have access to the permanent token required to authenticate and can’t access your Kubernetes cluster. This also results in the frozen Loading namespaces dialog.

Use the Azure Resource Manager Service Connection to access AKS

For AKS customers, the Azure Resource Manager service connection type provides the best method to connect to a private cluster, or a cluster that has local accounts disabled. This method is not dependent on cluster connectivity at the time you create a service connection. Access to AKS is deferred to pipeline runtime, which has the following advantages:

  • Access to a (private) AKS cluster can be performed from a self-hosted or scale set agent with line of sight to the cluster.
  • A token is created for every task that uses an Azure Resource Manager service connection. This ensures you are connecting to Kubernetes with a short-lived token, which is the Kubernetes recommendation.
  • AKS can be accessed even when local accounts are disabled.

Service connection FAQ

I receive the following error message: Could not find any secret associated with the service account. What is happening?

You are using the Kubernetes service connection with Azure Subscription option. We are updating this method to create long-lived tokens. This is expected to be available mid-May. However, it is recommended to start using the Azure service connection type and not o use long-lived tokens as per Kubernetes guidance.

I'm using AKS and don't want to change anything, can I continue to use tasks with the Kubernetes service connection?

We are updating this method to create long-lived tokens. This is expected to be available mid-May. However, please be aware that this approach is against Kubernetes guidance.

I'm using the Kubernetes tasks and Kubernetes service connection but not AKS. Should I be concerned?

You tasks will continue to work as before.

Will the Kubernetes service connection type be removed?

Our Kubernetes tasks work with any Kubernetes cluster, regardless where they are running. The Kubernetes service connection will continue to exist.

I’m an AKS customer and everything is running fine, should I act?

There is no need to change anything. If you are using the Kubernetes service connection and selected Azure Subscription during creation, you should be aware of the Kubernetes guidance on using long-lived tokens.

I'm creating a Kubernetes Environment, and have no option to use service connections

In case you can’t access your AKS during environment creation time, you can use an empty environment and set the connectionType input to an Azure Resource Manager service connection.

I have AKS configured with Azure Active Directory RBAC, and my pipeline doesn’t work. Will these updates resolve that?

Accessing Kubernetes when AAD RBAC is enabled is unrelated to token creation. To prevent an interactive prompt, we will support kubelogin in a future update.

Commands

The command input accepts kubectl commands.

This YAML example demonstrates the apply command:

- task: Kubernetes@1
  displayName: kubectl apply using arguments
  inputs:
    connectionType: Azure Resource Manager
    azureSubscriptionEndpoint: $(azureSubscriptionEndpoint)
    azureResourceGroup: $(azureResourceGroup)
    kubernetesCluster: $(kubernetesCluster)
    command: apply
    arguments: -f mhc-aks.yaml

This YAML example demonstrates the use of a configuration file with the apply command:

- task: Kubernetes@1
  displayName: kubectl apply using configFile
  inputs:
    connectionType: Azure Resource Manager
    azureSubscriptionEndpoint: $(azureSubscriptionEndpoint)
    azureResourceGroup: $(azureResourceGroup)
    kubernetesCluster: $(kubernetesCluster)
    command: apply
    useConfigurationFile: true
    configuration: mhc-aks.yaml

This YAML example shows the use of how to use the scale command to decrease the number of replicas in a deployment to 0.

- task: Kubernetes@1
      displayName: 'Scale down deployment $(k8sDeployment) to 0'
      inputs:
        connectionType: 'Kubernetes Service Connection'
        kubernetesServiceEndpoint: $(kubernetesServiceConnection)
        command: 'scale'
        arguments: 'deployment/$(k8sDeployment) --replicas=0'
        namespace: $(namespace)

Secrets

Kubernetes objects of type secret are intended to hold sensitive information such as passwords, OAuth tokens, and ssh keys. Putting this information in a secret is safer and more flexible than putting it verbatim in a pod definition or in a Docker image. Azure Pipelines simplifies the addition of ImagePullSecrets to a service account, or setting up of any generic secret, as described below.

ImagePullSecret

This YAML example demonstrates the setting up of ImagePullSecrets:

    - task: Kubernetes@1
      displayName: kubectl apply for secretType dockerRegistry
      inputs:
        azureSubscriptionEndpoint: $(azureSubscriptionEndpoint)
        azureResourceGroup: $(azureResourceGroup)
        kubernetesCluster: $(kubernetesCluster)
        command: apply
        arguments: -f mhc-aks.yaml
        secretType: dockerRegistry
        containerRegistryType: Azure Container Registry
        azureSubscriptionEndpointForSecrets: $(azureSubscriptionEndpoint)
        azureContainerRegistry: $(azureContainerRegistry)
        secretName: mysecretkey2
        forceUpdate: true

Generic Secrets

This YAML example creates generic secrets from literal values specified for the secretArguments input:

    - task: Kubernetes@1
      displayName: secretType generic with literal values
      inputs:
        azureSubscriptionEndpoint: $(azureSubscriptionEndpoint)
        azureResourceGroup: $(azureResourceGroup)
        kubernetesCluster: $(kubernetesCluster)
        command: apply
        arguments: -f mhc-aks.yaml
        secretType: generic
        secretArguments: --from-literal=contoso=5678
        secretName: mysecretkey

Pipeline variables can be used to pass arguments for specifying literal values, as shown here:

    - task: Kubernetes@1
      displayName: secretType generic with pipeline variables
      inputs:
        azureSubscriptionEndpoint: $(azureSubscriptionEndpoint)
        azureResourceGroup: $(azureResourceGroup)
        kubernetesCluster: $(kubernetesCluster)
        command: apply
        arguments: -f mhc-aks.yaml
        secretType: generic
        secretArguments: --from-literal=contoso=$(contosovalue)
        secretName: mysecretkey

ConfigMap

ConfigMaps allow you to decouple configuration artifacts from image content to maintain portability for containerized applications.

This YAML example creates a ConfigMap by pointing to a ConfigMap file:

    - task: Kubernetes@1
      displayName: kubectl apply
      inputs:
        configMapName: myconfig
        useConfigMapFile: true
        configMapFile: src/configmap

This YAML example creates a ConfigMap by specifying the literal values directly as the configMapArguments input, and setting forceUpdate to true:

    - task: Kubernetes@1
      displayName: configMap with literal values
      inputs:
        azureSubscriptionEndpoint: $(azureSubscriptionEndpoint)
        azureResourceGroup: $(azureResourceGroup)
        kubernetesCluster: $(kubernetesCluster)
        command: apply
        arguments: -f mhc-aks.yaml
        secretType: generic
        secretArguments: --from-literal=contoso=$(contosovalue)
        secretName: mysecretkey4
        configMapName: myconfig
        forceUpdateConfigMap: true
        configMapArguments: --from-literal=myname=contoso

You can use pipeline variables to pass literal values when creating ConfigMap, as shown here:

    - task: Kubernetes@1
      displayName: configMap with pipeline variables
      inputs:
        azureSubscriptionEndpoint: $(azureSubscriptionEndpoint)
        azureResourceGroup: $(azureResourceGroup)
        kubernetesCluster: $(kubernetesCluster)
        command: apply
        arguments: -f mhc-aks.yaml
        secretType: generic
        secretArguments: --from-literal=contoso=$(contosovalue)
        secretName: mysecretkey4
        configMapName: myconfig
        forceUpdateConfigMap: true
        configMapArguments: --from-literal=myname=$(contosovalue)

Troubleshooting

My Kubernetes cluster is behind a firewall and I am using hosted agents. How can I deploy to this cluster?

You can grant hosted agents access through your firewall by allowing the IP addresses for the hosted agents. For more details, see Agent IP ranges
