エラー内容

Error running connection boilerplate: Error checking and/or regenerating the certs: There was an error validating certificates for host "192.168.56.101:2376": dial tcp 192.168.56.101:2376: i/o timeout
You can attempt to regenerate them using 'docker-machine regenerate-certs name'.
Be advised that this will trigger a Docker daemon restart which will stop running containers.

$ docker-machine rm dev # => 削除
$ docker-machine create --driver virtualbox --virtualbox-hostonly-cidr 192.168.60.1/24 dev # => optionを追加してcreate
$ docker-machine env dev
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.60.101:2376"
export DOCKER_CERT_PATH="/Users/xxxxxx/.docker/machine/machines/dev"
export DOCKER_MACHINE_NAME="dev"
# Run this command to configure your shell:
# eval "$(docker-machine env dev)"

以上です。
