Reading Time: 9 minutes

What is Puppet?

In this tutorial, we will install Puppet on a Ubuntu 18.04 server. Puppet is an open core, server based, task management type of automation software that is primarily used to limit your interactions for many of the mundane, day to day server tasks that used to require personal intervention. 

This software allows you as the server owner to delegate specific functions to the software, thereby freeing you up for more critical business efforts. Puppet is a master/client based system that can interact with both Windows and Linux servers. The Puppet master server is run from a Linux server (a small downside given the time and effort it will save in the long run) but, can control efforts on other server types as well.

Using a Cron Wrapper Script

Reading Time: 4 minutes

This tutorial is intended to do two things: to expand on the Cron Troubleshooting article; and to give an overview of a simple scripting concept that uses the creation of a file as a flag to signify something is running. This is primarily useful when you need to run something continuously, but not more than one copy at a time. You can create a file as a flag to check if a job is already running, , and in turn, check for that flag before taking further action. Continue reading “Using a Cron Wrapper Script”

How To Install Docker on Ubuntu 16.04

Reading Time: 7 minutes

Adding Docker to an Ubuntu server.

Docker is an open-source software tool designed to automate and ease the process of creating, packaging, and deploying applications using an environment called a container. The use of Linux containers to deploy applications is called containerization. A Container allows us to package an application with all of the parts needed to run an application (code, system tools, logs, libraries, configuration settings and other dependencies) and sends it out as a single standalone package deployable via Ubuntu (in this case 16.04 LTS). Docker can be installed on other platforms as well. Currently, the Docker software is maintained by the Docker community and Docker Inc. Check out the official documentation to find more specifics on Docker. Docker Terms and Concepts. Continue reading “How To Install Docker on Ubuntu 16.04”
