March 2022 Linux Agent Release

Summary of Changes/Improvements

  • 5.4.2 - This minor release addresses an issue where the agent could, in rare circumstances, incorrectly identify the container associated with a connection in a multi-container K8S pod.

  • Origin value for now set as Lacework - The Label and Origin values are now set to Lacework on agent packages instead of the OS value. Issue a sudo apt update -y command to overwrite package repo information in the local apt cache to reflect the updated Label and Origin fields, and use the newly generated repository.

  • Enhanced Lacework Helm chart configurations - Starting in Agent v5.4.1, you can configure custom labels to the agent Helm chart. You can also reference existing secrets in your Helm charts (instead of creating a new secret).

    • Add proxy configuration to Agent Helm charts - Lacework supports a new proxyUrl parameter that specifies a proxy server URL to route agent traffic.

    • Allow custom labels to be added to Helm chart - Lacework allows you to associate customized labels to resources created by the Helm chart to distinguish and identify the resources with a new labels parameter.

  • Ecosystem certification - Lacework now supports the following new certified ecosystems, allowing you to deploy agents to these environments with assurance.

    • Flatcar Container
    • Linkerd
    • Azure Kubernetes (AKS)
  • Use Ubuntu 21.04 images for datacollector docker images - Lacework now uses Ubuntu version 21.04 as the base image for the agent’s Docker image. Previously, the Docker images were based on Ubuntu version 18.04.

  • Modify the Install script of the Lacework Docker Agent on a GCE host - You can now use the agent install script to install a Dockerized agent on a GCE host. See Install on a GCE Host for details.
