Quickstart on Kubernetes

This quickstart guide will help you install the LevoAI eBPF Sensor on a Kubernetes cluster.

Prerequisites​

  • Kubernetes version >= v1.18.0
  • Helm v3 installed and working.
  • The Kubernetes cluster API endpoint should be reachable from the machine you are running Helm.
  • kubectl access to the cluster, with cluster-admin permissions.
  • At least 4 CPUs
  • At least 8 GB RAM

Copy Authorization Key from Levo.ai​

The Satellite uses an authorization key to access Levo.ai.

  • Login to Levo.ai.
  • Click on your user profile.
  • Click on User Settings
  • Click on Keys on the left navigation panel
  • Click on Get Satellite Authorization Key

Copy your authorization key. This key is required in subsequent steps below.

Add Helm Charts Repository​

helm repo add levoai https://charts.levo.ai && helm repo update levoai

Add LevoAI Auth Key​

export LEVOAI_AUTH_KEY=<'Authorization Key' copied earlier>

Install Satellite​

helm upgrade --install -n levoai --create-namespace \
  --set global.levoai_config_override.onprem-api.refresh-token=$LEVOAI_AUTH_KEY \
  levoai-satellite levoai/levoai-satellite
info

Please refer to install satellite in kubernetes for detailed instructions.

Check satellite connectivity​

Execute the following to check for connectivity health:

# Please specify the actual pod name for levoai-tagger below
kubectl -n levoai logs <levoai-tagger pod name> | grep "Ready to process; waiting for messages."

If connectivity is healthy, you will see output similar to below.

{"level": "info", "time": "2022-06-07 08:07:22,439", "line": "rabbitmq_client.py:155", "version": "fc628b50354bf94e544eef46751d44945a2c55bc", "module": "/opt/levoai/e7s/src/python/levoai_e7s/satellite/rabbitmq_client.py", "message": "Ready to process; waiting for messages."}

Install eBPF Sensor​

# Replace 'levoai-haproxy' with the values you noted down from previous step if 
# Sensor was installed on a different cluster than satellite.
# Use appropriate environment value for levoEnv to segregate API assets in Levo dashboard.

helm upgrade levoai-sensor levoai/levoai-ebpf-sensor \
  --install \
  --namespace levoai \
  --create-namespace \
  # --set sensor.satelliteUrl=levoai-haproxy \
  --set sensor.levoEnv=<Application environment>

Check sensor health​

# Please specify the actual pod name for levoai-sensor below
kubectl -n levoai logs <levoai-sensor pod name> | grep "Initial connection with Collector"

If connectivity is healthy, you should see output similar to below.

2022/06/13 21:15:40 729071  INFO [ebpf_sensor.cpp->main:120]    Initial connection with Collector was successful.

Please contact support@levo.ai if you notice health/connectivity related errors.
