Resolvido.
- Primeiro eu mudei o daemon para rodar na porta 2375
- Depois, defino a variável de ambiente como
DOCKER_HOST=<ip>:2375 - Finalmente, consegui comunicar o
docker ps
Eu criei uma VM do VirtualBox com o Ubuntu 16 e o Docker 17.12.0-ce, esse host do docker se chama dockervm e está escutando na porta 2373 .
Agora, em uma máquina Windows (no prompt), eu defino DOCKER_HOST=tcp://dockervm:2373 e executo o comando docker ps e recebo:
error during connect: Get https://dockervm:2373/v1.35/containers/json: http: server gave HTTP response to HTTPS client
Como posso controlar remotamente este host do docker sem host de encaixe seguro ?
Agora eu tentei controlar o host remoto do docker via SSH ( tutorial ) mas quando eu crio o docker-machine eu tenho isso:
PS C:\Users\Roberto> docker-machine create --driver generic --generic-ip-address=192.168.15.115 --generic-ssh-key "c:/users/roberto/.ssh/id_rsa" --generic-ssh-user=jjw ubuntu

You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which might stop running containers.
