Aruba Cloud Driver for Docker Machine

Table of Contents

Overview

The Aruba Cloud Driver is a plugin for Docker Machine which allows you to automate the provisioning of Docker hosts on Aruba Cloud Servers. The plugin is based on the Go Aruba Cloud SDK and Cloud API.

To acquire Aruba Cloud Cloud API credentials visit https://www.cloud.it.

Requirements

Windows and Mac OS X users may install Docker Toolbox package that includes the latest version of the Docker Machine.

Installation

From a Release

The latest version of the docker-machine-driver-arubacloud binary is available on the GithHub Releases page. Download the tar archive and extract it into a directory residing in your PATH. Select the binary that corresponds to your OS and according to the file name prefix:

  • Linux: docker-machine-driver-arubacloud-linux
  • Windows: docker-machine-driver-arubacloud-windows

To extract and install the binary, Linux and Mac users can use the Terminal and the following commands:

sudo tar -C /usr/local/bin -xvzf docker-machine-driver-arubacloud*.tar.gz

If required, modify the permissions to make the plugin executable:

sudo chmod +x /usr/local/bin/docker-machine-driver-arubacloud

Windows users may run the above commands without sudo in Docker Quickstart Terminal that is installed with Docker Toolbox.

Otherwise Windows users can extract the zip manually and add the plugin folder to the PATH environment variable.

From Source

Make sure you have installed Go and configured GOPATH properly.

To download the repository and build the driver run the following:

go get -d -u github.com/Arubacloud/docker-machine-driver-arubacloud
cd $GOPATH/src/github.com/Arubacloud/docker-machine-driver-arubacloud
make build

To use the driver run:

make install

This command will install the driver into /usr/local/bin.

Otherwise, set your PATH environment variable correctly. For example:

export PATH=$GOPATH/src/github.com/Arubacloud/docker-machine-driver-arubacloud/bin:$PATH

If you are running Windows, you may also need to install GNU Make, Bash shell and a few other Bash utilities available with Cygwin.

Usage

You may want to refer to the Docker Machine official documentation before using the driver.

Verify that Docker Machine can see the Aruba Cloud driver:

docker-machine create -d arubacloud --help

Examples

Create using defaults:

docker-machine create --driver arubacloud \
 --ac_username		              "ARU-XXXX" \
 --ac_password			          "xxxxxxx" \
 --ac_admin_password		      "yyyyyyyy" \ 
MyDockerHostName

Create a Smart machine specifying template, endpoint and size:

docker-machine create --driver arubacloud \
 --ac_username		              "ARU-XXXX" \
 --ac_password			          "xxxxxxx" \
 --ac_endpoint			          "dc1" \
 --ac_template	                  "ubuntu1404_x64_1_0" \
 --ac_size				          "Large" \
 --ac_admin_password		      "yyyyyyyy" \ 
 --ac_action		      		  "NewSmart" \ 
MyDockerHostName

Create a Pro machine specifying template, endpoint and size:

If you don't specify an IP Address a new one will be automatically purchased.

docker-machine create --driver arubacloud \
 --ac_username		              "ARU-XXXX" \
 --ac_password			          "xxxxxxx" \
 --ac_endpoint			          "dc1" \
 --ac_template	                  "ubuntu1404_x64_1_0" \
 --ac_size				          "Large" \
 --ac_admin_password		      "yyyyyyyy" \ 
 --ac_action		      		  "NewPro" \ 
MyDockerHostName

Create a Pro machine specifying template, endpoint, size and IPAddress:

docker-machine create --driver arubacloud \
 --ac_username		              "ARU-XXXX" \
 --ac_password			          "xxxxxxx" \
 --ac_endpoint			          "dc1" \

Attach to an existing machine:

Note:

  • In order to attach to an existing machine, this machine must have been created with an SSH key.
  • You must put private and public key in the same folder on the machine where docker-machine commands will be launched, and pass this folder as an argument (Eg. --ac_ssh_key="private_key_path").
  • The name of the machine must be the same that is visible on Aruba Cloud Dashboard
docker-machine create --driver arubacloud \
 --ac_username		              "ARU-XXXX" \
 --ac_password			          "xxxxxxx" \
 --ac_endpoint			          "dc1" \

Get the IP address

docker-machine ip MyDockerHostName

Verify Docker Engine

Verify Docker Engine is installed correctly by running docker commands.

Start with something basic like docker run hello-world, or for a more interesting test, run a Dockerized webserver on your new remote machine.

In this example, the -p option is used to expose port 80 from the nginx container and make it accessible on port 8000 of the host.

$ docker run -d -p 8000:80 --name webserver kitematic/hello-world-nginx
 Unable to find image 'kitematic/hello-world-nginx:latest' locally
 latest: Pulling from kitematic/hello-world-nginx

In a web browser, go to http://<host_ip>:8000 to bring up the webserver home page. You got the <host_ip> from the output of the docker-machine ip command you ran in a previous step. Use the port you exposed in the docker run command.
