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.
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.
Switch to the docker user.
# su - docker
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.
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.
