In this tutorial, you’ll install and use Docker Community Edition (CE) on Ubuntu 20.04. They’re similar to virtual machines, but containers are more portable, more resource-friendly, and more dependent on the host operating system.įor a detailed introduction to the different components of a Docker container, check out The Docker Ecosystem: An Introduction to Common Components.

Otherwise, all cockroach start defaults are accepted. The -join flag specifies the hostname of each node that will initially comprise your cluster.
