CircleCI is used to run unit tests on Unix env.

/!\ Disclaimer: the datadog-agent-runner-circle image should never be used for anything else than CircleCI tests /!\

Change the Golang version in this file images/runner/Dockerfile.

Then locally build and push the new image using datadog/datadog-agent-runner-circle:go<new golang version> for the image's name. You will need write access to that repo on DockerHub (the Agent's team should have it).

Example:

cd .circleci/images/runner
docker build --platform=linux/amd64 -t datadog/datadog-agent-runner-circle:go1195 .
docker login
docker push datadog/datadog-agent-runner-circle:go1195

Once your image is pushed, update this file: https://github.com/DataDog/datadog-agent/blob/main/.circleci/config.yml. Change image: datadog/datadog-agent-runner-circle:goXXXX for the tag you just pushed.

Push your change as a new PR to see if CircleCI is still green.

If everything is green, get a review and merge the PR.
