Katib Examples with Argo Workflows Integration

Here you can find examples of using Katib with Argo Workflows.

Note: You have to install Argo >= v3.1 to use it in Katib Experiments.

Installation

To deploy Argo Workflows v3.1.3, run the following commands:

kubectl create namespace argo
kubectl apply -n argo -f https://github.com/argoproj/argo-workflows/releases/download/v3.1.3/install.yaml

Check that Argo Workflow components are running:

$ kubectl get pods -n argo

NAME                                  READY   STATUS    RESTARTS   AGE
argo-server-5bbd69cc6b-6nvb6          1/1     Running   0          20s
workflow-controller-5f48fb7c8-vw9bp   1/1     Running   0          20s

After that, run below command to enable Katib Metrics Collector sidecar injection:

kubectl patch namespace argo -p '{"metadata":{"labels":{"katib-metricscollector-injection":"enabled"}}}'

Note: Argo Workflows are using docker as a default container runtime executor. Since Katib is using Metrics Collector sidecar container and Argo Workflows controller should not kill sidecar containers, you have to modify this executor to emissary.

Run the following command to change the containerRuntimeExecutor to emissary in the Argo workflow-controller-configmap

kubectl patch ConfigMap -n argo workflow-controller-configmap --type='merge' -p='{"data":{"containerRuntimeExecutor":"emissary"}}'

Verify that containerRuntimeExecutor has been modified:

$ kubectl get ConfigMap -n argo workflow-controller-configmap -o yaml | grep containerRuntimeExecutor

  containerRuntimeExecutor: emissary
