# Driver options and operating system defaults
|
|
|
|
When Docker Machine provisions containers on local network provider or with a
|
|
remote, cloud provider such as Amazon Web Services, you must define both the
|
|
driver for your provider and a base operating system. There are over 10
|
|
supported drivers and a generic driver for adding machines for other providers.
|
|
|
|
Each driver has a set of options specific to that provider. These options
|
|
provide information to machine such as connection credentials, ports, and so
|
|
forth. For example, to create an Azure machine:
|
|
|
|
Grab your subscription ID from the portal, then run `docker-machine create` with
|
|
these details:
|
|
|
|
```bash
|
|
$ docker-machine create -d azure --azure-subscription-id="SUB_ID" --azure-subscription-cert="mycert.pem" A-VERY-UNIQUE-NAME
|
|
```
|
|
|
|
To see a list of providers and review the options available to a provider, see
|
|
the [Docker Machine driver reference](/drivers).
|
|
|
|
In addition to the provider, you have the option of identifying a base operating
|
|
system. It is an option because Docker Machine has defaults for both local and
|
|
remote providers. For local providers such as VirtualBox, Fusion, Hyper-V, and
|
|
so forth, the default base operating system is Boot2Docker. For cloud providers,
|
|
the base operating system is the latest Ubuntu LTS the provider supports.
|
|
|
|
| Operating System | Version | Notes |
|
|
|----------------------------|------------------|-------------------------|
|
|
| Boot2Docker | 1.5+ | default for local |
|
|
| Ubuntu | 12.04+ | default for remote |
|
|
| RancherOS | 0.3+ | |
|
|
| Debian | 8.0+ | experimental |
|
|
| RedHat Enterprise Linux | 7.0+ | experimental |
|
|
| CentOS | 7+ | experimental |
|
|
| Fedora | 21+ | experimental |
|
|
|
|
To use a different base operating system on a remote provider, specify the
|
|
provider's image flag and one of its available images. For example, to select a
|
|
`debian-8-x64` image on DigitalOcean you would supply the
|
|
`--digitalocean-image=debian-8-x64` flag.
|
|
|
|
If you change the base image for a provider, you may also need to change
|
|
the SSH user. For example, the default Red Hat AMI on EC2 expects the
|
|
SSH user to be `ec2-user`, so you would have to specify this with
|
|
`--amazonec2-ssh-user ec2-user`. |
