After upgrading to Docker Engine 29, Drone/Harness pipelines failed with: unable to connect to docker engine: Error response from daemon: client version 1.41 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer version. The bundled Drone runner image used an old Docker client (API 1.41) while Docker Engine 29 raised its minimum accepted API version to 1.44, so the runner could no longer talk to the daemon.

The bundled Drone runner client (API 1.41) was rejected by Docker Engine 29's raised minimum API version (1.44). Options: upgrade Docker Engine to 29.3.0 or later, which dropped the minimum accepted API version back to 1.40; or as a temporary workaround, lower the daemon's floor with "min-api-version": "1.24" in daemon.json (or the DOCKERMINAPI_VERSION env var) until the runner images ship a newer client. Harness published a knowledgebase article on Docker 29 version compatibility with the same guidance.
