CI/CD Observability


tracepusher is a new Open Source project that provides a Python script to send traces to OpenTelemetry. The script can be run standalone on the command-line or integrated into GitLab CI/CD pipelines. The CI/CD configuration needs to be extended with a preparation job to generate a unique trace ID for the pipeline run, and consecutive before_script and after_script default definitions for all jobs to generate span IDs, and emit the trace span to OpenTelemetry with the tracepusher script, with a post pipeline job that finalizes the trace. You can create a quick demo setup with an OpenTelemetry collector that accepts HTTP messages using this project which docker-compose.

You can then follow my public learning curve implementing tracepusher into the slow pipeline project in this MR. I also created upstream pull requests and issues, including emphasis on the CI-tagged image, jobs that specify a custom image, before_script/after_script override problem workarounds and Jobs with needs do not download dotenv artifacts by default, causing new trace IDs generated.
