Docker Machine Driver

This is the official Docker Machine driver for use with the IONOS Cloud.

Getting Started

Before you begin you will need to have signed-up for a IONOS account. The credentials you establish during sign-up will be used to authenticate when using the Docker Machine driver..

Install Docker Machine

This IONOS plugin will only work with Docker Machine. Before we continue, you will need to install Docker Machine. Docker Machine is included as part of Docker Toolbox. You can gain access to docker-machine by installing Docker Toolbox on Mac OS X or Windows. It is also possible to install just Docker Machine without the rest of the components of Docker Toolbox.

Install Go

The ProfitBricks Docker Machine Driver is written in the Go programming language. Your system will need to have Go installed. Please refer to the Go Install Documentation if you do not have Go installed and configured for your system.

Remember to set $GOPATH and update $PATH. The following are just examples using the export command, you will need to adjust the paths for your particular installation.

export GOPATH=/usr/local/go
export PATH=$PATH:/usr/local/go/bin

Install Driver

With those prerequisites taken care of, we will need to run the following commands to install the ProfitBricks Docker Machine driver:

go get

If you just installed Go, you may get an error indicating the need to configure the $GOPATH environment variable. Once $GOPATH is set properly, the command should complete successfully.

Next we need to build and install the driver itself.

cd $GOPATH/src/
make install

When successful, we will end up with a newly created docker-machine-driver-profitbricks binary in $GOPATH/bin/.

Create a Machine

Before you create a ProfitBricks machine you will need to set two environment variables containing your ProfitBricks credentials. These would be the same username and password that you use to log into the ProfitBricks DCD (Data Center Designer):

export PROFITBRICKS_USERNAME="profitbricks_username"
export PROFITBRICKS_PASSWORD="profitbricks_password"

It is possible to pass your credentials on the command-line using --profitbricks-username and --profitbricks-password if you prefer.

Now run docker-machine create with the relevant parameters. This example will use mostly default values and will therefore be created in the us/las location.

docker-machine create --driver profitbricks test-machine

It should produce results similar to this:

Running pre-create checks...
Creating machine...
(test-machine) Datacenter Created
(test-machine) Server Created
(test-machine) Volume Created
(test-machine) Attached a volume  to a server.
(test-machine) LAN Created
(test-machine) NIC created
(test-machine) Updated server's boot image
Waiting for machine to be running, this may take a few minutes...
Detecting operating system of created instance...
Waiting for SSH to be available...
Detecting the provisioner...
Provisioning with ubuntu(systemd)...
Installing Docker...
Copying certs to the local machine directory...
Copying certs to the remote machine...
Setting Docker configuration on the remote daemon...
Checking connection to Docker...
Docker is up and running!
To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env test-machine

To get detailed information about the possible options, run the command:

docker-machine create --help --driver profitbricks

Available Options

This section describes the available options that can be set. Many of these options can also be set using environment variables. Several of the standard Docker Machine options may be specified multiple times if desired. The ProfitBricks specific options are prefixed with --profitbricks- and the corresponding environment variables have $PROFITBRICKS_ as the prefix.

Option Name(s) Description including [ENV variable]
--driver, -d "profitbricks" The driver to create a new machine with. Set this to "profitbricks" in order to use Docker Machine with ProfitBricks resources. [$MACHINE_DRIVER]
--engine-env "opt" Specify one or more environment variables to set in the engine.
--engine-insecure-registry "opt" Specify which insecure registries to allow with the created engine.
--engine-install-url "" Custom URL to use for engine installation. [$MACHINE_DOCKER_INSTALL_URL]
--engine-label "opt" Specify labels for the created engine.

--profitbricks-datacenter-id "8fc590c3-4cfb-4702-8bd6-XXXXXXXXXX" The ProfitBricks Virtual Data Center Id. If you want to use an existing ProfitBricks Virtual Data Center (VDC), then you can specify a UUID with this option. If you don't specify one, then a new VDC is created.
--profitbricks-disk-size "50" The ProfitBricks volume/disk size in GB. (10, 50, 100, 200, 400) [$PROFITBRICKS_DISK_SIZE]
--profitbricks-disk-type "HDD" The ProfitBricks disk type. You have two choices, either spinning hard disk drive (HDD) storage, or solid state drive (SSD) storage. (HDD, SSD) [$PROFITBRICKS_DISK_TYPE]
--profitbricks-endpoint "" The ProfitBricks Cloud API endpoint. [$PROFITBRICKS_ENDPOINT]
--profitbricks-image "Ubuntu-16.04" A ProfitBricks image name. You have the option to use an image alias such as: "Ubuntu:latest" or a partial image name such as: "Ubuntu-16.04". [$PROFITBRICKS_IMAGE]
--profitbricks-location "us/las" A ProfitBricks regional location. This specifies a physical data center regional location where your VDC exists or will be provisioned. There are currently four available locations: (us/las, us/ewr, de/fkb, and de/fra) [$PROFITBRICKS_LOCATION]

To list the machines you have created, use the command:

docker-machine ls

It will return information about your machines, similar to this:

NAME           ACTIVE   DRIVER         STATE     URL                         SWARM   DOCKER    ERRORS
default        -        virtualbox     Running   tcp://           v1.10.2
test-machine   -        profitbricks   Running   tcp://           v1.10.3

Create a Swarm

Before you create a swarm of ProfitBricks machines, run this command:

docker run --rm swarm create

Then use the output to create the swarm and set a swarm master:

docker-machine create -d profitbricks --swarm --swarm-master --swarm-discovery token://f3a75db19a03589ac28550834457bfc3 swarm-master-test

To create a swarm child, use the command:

docker-machine create -d profitbricks --swarm --swarm-discovery token://f3a75db19a03589ac28550834457bfc3 swarm-child-test
