Docker tools

Docker client applications, including the Docker CLI, can connect to the Triton remote API endpoint to launch and control Docker containers on bare metal across an entire Triton data center. Each data center is a single Triton Elastic Docker Host endpoint.

Quick start

There are just three steps to using Docker on Triton:

  1. Install Triton CLI
  2. Install Triton Docker CLI
  3. Work with Docker containers on Triton

Watch a video to learn more about the Triton Docker Elastic Host and how to get started with the Triton Docker CLI tool.

Install Triton CLI

In order to interact with Docker and other containers on Triton, you must install the Triton CLI tool and set up Triton CLI profiles.

You can use Triton CLI profiles for different data centers and different users. You can switch between profiles by specifying the profile name, as in: triton env <profile name>1.

If your Triton profile was created before Triton CLI version 4.9, you'll have to update it for Docker:

triton profile docker-setup <profile name>

Please see contact support if you encounter any difficulty.

Install Triton Docker CLI

Configuring Docker for Triton requires the Triton Docker CLI, which installs known good versions of the Docker and Docker Compose CLI tools for use with Triton. This script will automatically configure those tools for use with Triton when you use them, making it easy to switch between Docker on your laptop and Docker on Triton.

In a terminal window, run the following command:

sudo bash -c 'curl -o /usr/local/bin/triton-docker && chmod +x /usr/local/bin/triton-docker && ln -Fs /usr/local/bin/triton-docker /usr/local/bin/triton-compose && ln -Fs /usr/local/bin/triton-docker /usr/local/bin/triton-docker-install'

That command will copy the triton-docker shell script from this repo, and link it as triton-compose and triton-docker-install.

To complete the installation, run:

sudo triton-docker-install

This will install the platform-specific versions of the Docker and Docker Compose CLI tools. These versions will not replace any existing Docker or Docker Compose versions you may have installed.

To test Docker, you can run triton-docker info and see your account name in the output. We can see jill, our example user, in SDCAccount: jill here:

$ triton-docker info

You will need to install Docker to build and deploy images from your local environment. This should not be done on Triton or with triton-docker.

Install Docker to build locally

The Docker application should be installed to build and deploy images from your local environment.

Work with Docker containers

Once triton-docker has been installed, you'll be able to run containers on Triton. Get started:

It is possible to work directly with the docker CLI tool on Triton. If you choose not to install triton-docker, you can use docker commands almost exactly as you would on your local machine (with a some exceptions).

However, some docker commands will emit errors and certain newer features are not yet available on Triton. We advise you to use triton-docker, which installs Docker version 1.12.6 and Docker Compose 1.9.0, which have been tested with Triton.

Docker is an open source project and therefore can be released with bugs which will cause problems on Triton.

  1. If you have not installed triton-docker, then you should use eval "$(triton env <profile name>)" to switch between Triton profiles.
