Currently, when the 'docker-machine' command fails, we only logs "exit status 1' Which is not very helpful in root cause analysis. With this patch, the 'docker-machine' command's stderr output is also logged. # To cause docker-machine command fail $ export DOCKER_MACHINE_NAME=xx $ k3d create 2019/06/13 16:45:31 Created cluster network with ID 6fc91e0e5e912443e6b847f113a6a0bb85ccd610e5232592296d4b199f0347cf 2019/06/13 16:45:31 Error executing 'docker-machine ip' 2019/06/13 16:45:31 Docker machine "xx" does not exist. Use "docker-machine ls" to list machines. Use "docker-machine create" to add a new one. exit status 1
