The package manager will refresh the package list and see where an upgrade is available. To ensure we have all recent packages - Docker likes to be on an up to date system - we start with a full system upgrade: $ sudo yum update Kinamo cloud hosting customers using a cloud server and wish to deploy Docker, preferably use "sudo". If you are logged on as root, ommit the "sudo" at the commands below. We assume you are using a user that can obtain administrative privileges by using "sudo".
On this machine we will install Docker engine, allowing you to run a docker image (contaner) within docker engine. The cloud server we will use for this article is an empty, base CentOS 7 cloud server, as you can order at Kinamo. This article explains you how to get started with Docker engine on CentOS 7.
