Serverless

Status

Overview

Serverless Operator allows deploying the Serverless component in the Kyma cluster in compatibility with Lifecycle Manager.

Architecture Diagram

Install

Create the kyma-system namespace:

kubectl create namespace kyma-system

Apply the following script to install Serverless Operator:

kubectl apply -f https://github.com/kyma-project/serverless/releases/latest/download/serverless-operator.yaml

To get Serverless installed, apply the sample Serverless CR:

kubectl apply -f https://github.com/kyma-project/serverless/releases/latest/download/default-serverless-cr.yaml

Development

Prerequisites

• Access to a Kubernetes (v1.24 or higher) cluster
• Go
• k3d
• Docker
• kubectl
• Kubebuilder
• yq

Installation in the k3d Cluster Using Make Targets

1. Clone the project.

   git clone https://github.com/kyma-project/serverless.git && cd serverless/

2. Create a new k3d cluster and run Serverless from the main branch:

   make run-main

NOTE: To clean up the k3d cluster, use the make delete-k3d make target.

NOTE: If you have k3d already running, you can use the install-* targets to install Serverless in different flavors.

Using Serverless Operator

• Create a Serverless instance.

  kubectl apply -f config/samples/default-serverless-cr.yaml

• Delete a Serverless instance.

  kubectl delete -f config/samples/default-serverless-cr.yaml

• Use external registry.

  The following example shows how you can modify the Serverless Docker registry address using the serverless.operator.kyma-project.io CR:

  kubectl create secret generic my-secret \
      --namespace kyma-system \
      --from-literal username="<USERNAME>" \
      --from-literal password="<PASSWORD>" \
      --from-literal serverAddress="<SERVER_ADDRESS>" \
      --from-literal registryAddress="<REGISTRY_ADDRESS>"

  NOTE: For DockerHub:

  • SERVER_ADDRESS is "https://index.docker.io/v1/",
  • USERNAME and REGISTRY_ADDRESS must be identical.

  cat <<EOF | kubectl apply -f -
  apiVersion: operator.kyma-project.io/v1alpha1
  kind: Serverless
  metadata:
  name: serverless-sample
  spec:
      dockerRegistry:
          enableInternal: false
          secretName: my-secret
  EOF
