Quick Start Guide

Installing the latest Release

These quick start instructions assume you have a Kubernetes cluster available to you and kubectl is properly configured.

Install Kueue

Install and configure a compatible version of Kueue by executing this command:

kubectl apply --server-side -k "https://github.com/project-codeflare/appwrapper/hack/kueue-config?ref=v0.27.0"

Before continuing, ensure Kueue is ready by executing this command:

kubectl -n kueue-system wait --timeout=300s --for=condition=Available deployments --all

Finally, you need to create a default ClusterQueue and LocalQueue with a quota of 4 CPUs to enable Kueue to schedule workloads on your cluster. The yaml shown below accomplishes this:

apiVersion: kueue.x-k8s.io/v1beta1
kind: ResourceFlavor
metadata:
  name: "default-flavor"
---
apiVersion: kueue.x-k8s.io/v1beta1
kind: ClusterQueue
metadata:
  name: "cluster-queue"
spec:
  namespaceSelector: {} # match all.
  resourceGroups:
  - coveredResources: ["cpu"]
    flavors:
    - name: "default-flavor"
      resources:
      - name: "cpu"
        nominalQuota: 4
---
apiVersion: kueue.x-k8s.io/v1beta1
kind: LocalQueue
metadata:
  namespace: "default"
  name: "user-queue"
spec:
  clusterQueue: "cluster-queue"

You can either copy this yaml to your local file system and do a kubectl apply -f <name-of-local-file> or apply it remotely by doing:

kubectl apply -f https://raw.githubusercontent.com/project-codeflare/appwrapper/main/hack/default-queues.yaml

Install AppWrapper

Install the most recent AppWrapper release by doing:

kubectl apply --server-side -f https://github.com/project-codeflare/appwrapper/releases/download/v0.27.0/install.yaml

Before continuing, ensure AppWrappers are ready by executing this command:

kubectl -n appwrapper-system wait --timeout=300s --for=condition=Available deployments --all

Validate the Install

Finally, validate the installation by creating a simple AppWrapper and verifying that it runs as expected.

Create an AppWrapper by executing:

kubectl apply -f https://raw.githubusercontent.com/project-codeflare/appwrapper/v0.27.0/samples/wrapped-pod.yaml

You should quickly see an AppWrapper with the Running Status. The sample contains a single Pod with an init container that runs for 10 seconds, followed by a main container that runs for 5 seconds. After the main container completes, the Status of the AppWrapper will be Succeeded. We show some kubectl commands and their expected outputs below:

% kubectl get appwrappers
NAME         STATUS
sample-pod   Running

% kubectl get pods
NAME         READY   STATUS     RESTARTS   AGE
sample-pod   0/1     Init:0/1   0          14s

% kubectl get pods
NAME         READY   STATUS    RESTARTS   AGE
sample-pod   1/1     Running   0          18s

% kubectl get pods
NAME         READY   STATUS      RESTARTS   AGE
sample-pod   0/1     Completed   0          30s

% kubectl get appwrappers
NAME         STATUS
sample-pod   Succeeded

You can delete the AppWrapper with:

kubectl delete -f https://raw.githubusercontent.com/project-codeflare/appwrapper/v0.27.0/samples/wrapped-pod.yaml
