Container Resource Attributes Collection for Telemetry Data
- Harold Lim
For docker environments, some of the Kfuse APM UI relies on the container_id attribute to be attaches to the Resource attributes of the telemetry data received by Kfuse. In OpenTelemetry, attaching of the container attribute is done at each language SDK. The table below shows whether discovery and adding container_id as resource attribute is supported by the language SDK (out-of-the-box, as part of the resource detectors), when running on a Docker CGroupv2 environment.
Language | Container ID Support | Notes |

Python | Yes | opentelemetry-resource-detector-container is not yet published to pypi. As a workaround, use the following in requirements.txt 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 enviroment variable
