Feature Enhancements

Changes to Deploying the Serverless Agent

  • To prioritize between Security and Availability in deployments, configurable Serverless Agent Priority Modes have been introduced. For more information, see Configure Priority Modes.

  • To reduce the load on the Orchestrator Agent, the following changes are introduced:

    • A single Workload Agent sidecar will now secure all containers within a task, whereas before each container would run its own Workload Agent.
    • The Workload Agent now runs within the sidecar container with only the pdig instrumentation stack remaining in the workload container.

For this enhancements to work, your system requires one of the following:

  • serverless-patcher v5.0.0 or above for CloudFormation template
  • Terraform provider v1.23.3 or above

Availability of sysdig_serverless_agent_info

Serverless Agent now exposes the Prometheus metric, sysdig_serverless_agent_info. This metric provides the following labels:

  • agent_type
  • container_id
  • serverless_account_id
  • serverless_cloud_vendor
  • serverless_cluster_id
  • serverless_task_id
  • serverless_version

Known Issues

The Workload Agent versions 4.2 and prior will not receive policies when connected to the Orchestrator v5.0.0.

For more information, see the Compatibility Matrix.
