Install Kubeflow

Instructions for deploying Kubeflow with the shell

This guide describes how to use the kfctl binary to deploy Kubeflow on Azure.

Prerequisites

You do not need to have an existing Azure Resource Group or Cluster for AKS (Azure Kubernetes Service). You can create a cluster in the deployment process.

Understanding the deployment process

The deployment process is controlled by the following commands:

  • build - (Optional) Creates configuration files defining the various resources in your deployment. You only need to run kfctl build if you want to edit the resources before running kfctl apply.
  • apply - Creates or updates the resources.
  • delete - Deletes the resources.

App layout

Your Kubeflow application directory ${KF_DIR} contains the following files and directories:

  • ${CONFIG_FILE} is a YAML file that defines configurations related to your Kubeflow deployment.

  • kustomize is a directory that contains the kustomize packages for Kubeflow applications.

    • The directory is created when you run kfctl build or kfctl apply.
    • You can customize the Kubernetes resources (modify the manifests and run kfctl apply again).

If you experience any issues running these scripts, see the troubleshooting guidance for more information.

Azure setup

Login to Azure

az login

Initial cluster setup for new cluster

Create a resource group:

az group create -n <RESOURCE_GROUP_NAME> -l <LOCATION>

Example variables:

  • RESOURCE_GROUP_NAME=KubeTest
  • LOCATION=westus

Create a specifically defined cluster:

az aks create -g <RESOURCE_GROUP_NAME> -n <NAME> -s <AGENT_SIZE> -c <AGENT_COUNT> -l <LOCATION> --generate-ssh-keys

Example variables:

  • NAME=KubeTestCluster
  • AGENT_SIZE=Standard_D2_v2
  • AGENT_COUNT=3
  • Use the same resource group and name from the previous step

NOTE: If you are using a GPU based AKS cluster (For example: AGENT_SIZE=Standard_NC6), you also need to install the NVidia drivers on the cluster nodes before you can use GPUs with Kubeflow.

Kubeflow installation

Run the following commands to set up and deploy Kubeflow.

  1. Create user credentials. You only need to run this command once.

    az aks get-credentials -n <NAME> -g <RESOURCE_GROUP_NAME>
    
  2. Download the kfctl v0.7.0 release from the Kubeflow releases page.

  3. Unpack the tar ball

    tar -xvf kfctl_v0.7.0_<platform>.tar.gz
    
  4. Run the following commands to set up and deploy Kubeflow. The code below includes an optional command to add the binary kfctl to your path. If you don’t add the binary to your path, you must use the full path to the kfctl binary each time you run it.

    # The following command is optional, to make kfctl binary easier to use.
    export PATH=$PATH:<path to where kfctl was unpacked>
    
    # Set KF_NAME to the name of your Kubeflow deployment. This also becomes the
    # name of the directory containing your configuration.
    # For example, your deployment name can be 'my-kubeflow' or 'kf-test'.
    export KF_NAME=<your choice of name for the Kubeflow deployment>
    
    # Set the path to the base directory where you want to store one or more 
    # Kubeflow deployments. For example, /opt/.
    # Then set the Kubeflow application directory for this deployment.
    export BASE_DIR=<path to a base directory>
    export KF_DIR=${BASE_DIR}/${KF_NAME}
    
    # Set the configuration file to use, such as the file specified below:
    export CONFIG_URI="https://raw.githubusercontent.com/kubeflow/manifests/v0.7-branch/kfdef/kfctl_k8s_istio.0.7.0.yaml"
    
    # Generate and deploy Kubeflow:
    mkdir -p ${KF_DIR}
    cd ${KF_DIR}
    kfctl apply -V -f ${CONFIG_URI}
    
    • ${KF_NAME} - The name of your Kubeflow deployment. If you want a custom deployment name, specify that name here. For example, my-kubeflow or kf-test. The value of KF_NAME must consist of lower case alphanumeric characters or ‘-’, and must start and end with an alphanumeric character. The value of this variable cannot be greater than 25 characters. It must contain just a name, not a directory path. This value also becomes the name of the directory where your Kubeflow configurations are stored, that is, the Kubeflow application directory.

    • ${KF_DIR} - The full path to your Kubeflow application directory.

  5. Check the resources deployed correctly in namespace kubeflow

    kubectl get all -n kubeflow
    
  6. Open Kubeflow Dashboard

The default installation does not create an external endpoint but you can use port-forwarding to visit your cluster. Run the following command and visit http://localhost:8080.

kubectl port-forward svc/istio-ingressgateway -n istio-system 8080:80

In case you want to expose the Kubeflow Dashboard over an external IP, you can change the type of the ingress gateway. To do that, you can edit the service:

    kubectl edit -n istio-system svc/istio-ingressgateway

From that file, replace type: NodePort with type: LoadBalancer and save.

While the change is being applied, you can watch the service until below command prints a value under the EXTERNAL-IP column:

    kubectl get -w -n istio-system svc/istio-ingressgateway

The external IP should be accessible by visiting http://. Note that above installation instructions do not create any protection for the external endpoint so it will be accessible to anyone without any authentication. You can read more about authentication from Access Control for Azure Deployment.
