Docker & Container Runtimes

Display a list of available operating systems on Vultr in pretty JSON

Vultr, a Cloud hosting services provider, supports Docker Machine through their own Docker Machine driver, which you can install on Linux Mint 18 and Ubuntu 16.04 using this guide.

With the driver installed, you may then provision Dockerized hosts, or machines, on the Vultr platform using the docker-machine create command. A list of available operating systems on Vultr is accessible via this URL. That’s rendered by the browser in a JSON format that’s painful to read.

To obtain a JSON output that’s a lot more easy on the eyes, use the following curl command.

The output should be like the one shown below. Note that each operating system has an id.

Knowing the id of an operating system, you can now specify it when creating a Dockerized host on the Vultr platform. For example, to create a Dockerized host with Debian 8 Jessie, whose id is 193, as the base operating system, you would type the following command.
