Overview

Single Step Instrumentation (SSI) has specific compatibility requirements that vary by language and environment. This page outlines supported versions, known limitations, and conditions that may impact Single Step Instrumentation for your specific setup.

Operating systems

The following operating systems and architectures are compatible:

Platforms

The following container platforms are compatible:

Platform-specific requirements

Linux virtual machines (VMs)

You may encounter timeouts with smaller VM instances such as t2.micro. In this case, you should upgrade to a larger instance such as t2.small.

Docker containers

• Rootless Docker mode: If you are using Docker in rootless mode (that is, Docker running without root privileges for added security), you need to configure the socket path to ensure SSI can connect to Docker. Update the socket path in /etc/datadog-agent/inject/docker_config.yaml to match your environment. By default, this path is set to /run/user/$UID/docker.sock, but it may vary based on your setup.

• Custom runc shims: If your environment uses custom runc shims (for GPU support or other specialized tasks), you must adjust your configuration to avoid conflicts. SSI requires its own runc shim to enable automatic instrumentation within Docker containers. To ensure compatibility, update the runtimes property in /etc/datadog-agent/inject/docker_config.yaml to include both your custom shim and the Datadog shim.

Kubernetes with Windows pods

For Kubernetes clusters with Windows pods, use namespace inclusion/exclusion or specify an annotation in the application to exclude them from library injection.
