Use a Private Docker Registry for Kubernetes Installations

To use private images while installing Levo's services in your environment, you need to follow 3 steps:

  1. Copy Levo's public Docker images into your registry.
  2. Create a secret in your Kubernetes cluster with the credentials to access your private registry.
  3. Specify a values file to the Levo Helm chart to use your private registry.

Copy Levo's public Docker images into your registry​

An example bash script to do this for AWS ECR has been provided below. Please modify this script to suit your needs.

#!/usr/bin/env bash

# Dependencies: yq, helm, awscli, docker

set -e
trap "exit" INT

region="us-west-2"
registry="your.registry"

helm repo add levoai https://charts.levo.ai || true
helm repo update levoai
images=($(helm template levoai/levoai-satellite | yq -N '..|.image? | select(.)' | sort -u))
images+=($(helm template levoai/levoai-ebpf-sensor | yq -N '..|.image? | select(.)' | sort -u))

for image in "${images[@]}"; do
  src_image=${image#"docker.io/"}
  dest_image="$registry/$src_image"
  repo_name=${src_image%:*}
  aws ecr describe-repositories --repository-names $repo_name --region $region || aws ecr create-repository --repository-name $repo_name --region $region
  echo "Copying $src_image to $dest_image"
  docker buildx imagetools create --tag $dest_image $src_image
done

Create a secret in your Kubernetes cluster with the credentials to access your private registry​

Adapt the following command for your private registry:

kubectl create secret docker-registry ecr-auth --docker-server=your.registry --docker-username=AWS --docker-password=$(aws ecr get-login-password --region us-west-2)

Specify a values file to the Levo Helm chart to use your private registry​
