One-Click Docker

Introduction

The Vultr One-Click Docker application is a Docker CE host that's ready to run in about a minute. Vultr updates the application regularly, so you'll always have the latest platform for your Docker containers. One-Click Docker comes in both CentOS and Ubuntu flavors.

Pre-Configured User

It is a best practice to run containers as a limited user. One-Click Docker comes pre-configured with a docker user and group for security. If you have other limited users that need to run containers, add them to the docker group.

Installation Test

1. After One-Click Docker deploys, log in as root via SSH.

2. Switch to the docker user.

    # su - docker

3. Test the installation with the Hello World container.

    $ docker run hello-world
   
    Hello from Docker!
    This message shows that your installation appears to be working correctly.

More Information

• The CentOS flavor One-Click Docker offers SELinux support, which is disabled by default. See our guide to enable SELinux on CentOS if you plan to use this feature.
• We recommend the Docker documentation for comprehensive security information.

About One-Click Apps

One-Click apps are updated regularly without notice. When launching a One-Click app, you'll receive our latest version. We do not update deployed instances, and you are responsible for keeping the instance up-to-date. If you design an infrastructure based on One-Click apps and need to ensure the same app version in the future, take a snapshot of the initial deployment and create new instances from the snapshot.
