We’ve deployed Elastic Stack 5.0.0 with Docker 19.03.13 (verified) and enabled the experimental Docker functionality.
We’re trying to use the
--ssh default flag in our custom plugin to allow use of the SSH agent on the host. Docker however appears to be ignoring our specifying DOCKER_BUILDKIT=1 before running Docker, as well as ignoring it being specified in the pipeline’s environment. This results in the error
unknown flag: --ssh default
How do we enable Docker’s Buildkit with the Elastic CI Stack?
