Installation

This section shows us how to install operator in our cluster.

Requirements

  1. Kubernetes 1.24+
  2. Kubectl 1.24+

Please make sure the kubectl is properly configured to interact with the Kubernetes environment.

Preparing Images of Coordinators and Shuffle Servers

Run the following command:

cd deploy/kubernetes/docker && sh build.sh --registry ${our-registry}

This compiles RSS with Hadoop 2.8 support und add the Hadoop binaries to the Docker image. Use --hadoop-version x.y.z to choose a different Hadoop version. Use --hadoop-provided false to not include the Hadoop installation in the image.

Creating or Updating CRD

We can refer to crd yaml file.

Run the following command:

# create, cannot use apply here, see https://github.com/apache/incubator-uniffle/issues/774
kubectl create -f ${crd-yaml-file}

# update, make sure the crd-yaml-file is a complete CRD file.
kubectl replace -f ${crd-yaml-file}

Setup or Update Uniffle Webhook

We can refer to webhook yaml file.

Run the following command:

kubectl apply -f ${webhook-yaml-file}

Setup or Update Uniffle Controller

We can refer to controller yaml file.

Run the following command:

kubectl apply -f ${controller-yaml-file}
