Acesta este un mecanism prin care este oferită o interfață către câțiva provideri de servicii cloud.
Pentru a experimenta această interfață, vom folosi VirtualBox pentru mediul care ar simula cloud-ul.
docker-machine create --driver virtualbox docker-localRăsunsul va fi crearea unei mașini dedicate Docker.

To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env docker-local
Pentru a vedea detaliile vom rula docker-machine enc docker-local.
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/home/user1/.docker/machine/machines/docker-local"
export DOCKER_MACHINE_NAME="docker-local"
# Run this command to configure your shell:
# eval $(docker-machine env docker-local)
La instalarea Docker vei putea vedea ce mașini docker sunt instalate local:
$ docker-machine lsVor fi oferite detaliile mașinilor virtuale care vor găzdui containerele de lucru.

docker-local - virtualbox Running tcp://192.168.99.100:2376 v18.06.1-ce
Pentru că s-au creat chei de securitate, va fi posibilă comunicarea pe SSH.
docker-machine ssh docker-localȘi avem în acest moment acces la mașina virtuală.

Toți marii provideri de servicii de cloud permit instanțierea de mașini virtuale gata de a rula containere Docker.
