Container Resource Attributes Collection for Telemetry Data

For Docker environments, some of the Kfuse APM UI relies on the container_id attribute that attaches to the Resource attributes of the telemetry data received by Kloudfuse. In OpenTelemetry, this attachment is accomplished at the language SDK.

The following list provides the necessary information for you to properly configure your deployment when running on a Docker CGroupv2 environment.

.Net: Has container_id support.

C++: No container_id support.

Go: No container_id support.

Pending unmerged OpenTelemetry PR Detect container id on cgroup v2 #3501.

Java: Has container_id support.

JavaScript and Node.js: Has container_id support.

Use OpenTelemetry Resource Detector for Container. Pinned to version 0.2.2. Versions 0.3.* does not work; see opentelemetry-resource-detector-container does not detect the container id on 0.3.4/0.3.7.

Kotlin: Has container_id support.

Uses same sdk as java.

PHP: Has container_id support.

Python

Has container_id support.

Pending publication of resource/opentelemetry-resource-detector-container to pypi. As a workaround, use the following in requirements.txt file:

opentelemetry-resource-detector-container @ git+https://github.com/open-telemetry/opentelemetry-python-contrib.git@0.43b0hotfix#subdirectory=resource/opentelemetry-resource-detector-container

If using automatic instrumentation, add the following environment variable:

OTEL_EXPERIMENTAL_RESOURCE_DETECTORS=container

yaml

Ruby: Has container_id support.

Use OpenTelemetry::Resource::Detector::Container.

Rust: No container_id support.
