• Docker for Web Hosting 101

    Onyx Point

    Docker, and likewise Linux containers, have taken the development industry by storm. Legacy applications are being re-packaged as micro-services to break away from the heavy application installs and complex dependencies. Although lots of developers already use Docker on their machines for application testing, it's not always clear how Docker applications should be configured for a production web hosting environment. I'm Dan Healy, founder and systems engineer for Healy Technologies. I've accomplished an electrical engineering degree from Old Dominion University as well as a master's of IT and Systems Engineer from University of Maryland University College. My experience includes technical leadership with the Johns Hopkins University enterprise web hosting team and architecting a Docker-based web hosting replacement for student and faculty websites. I also serve as a Senior Systems Engineer for Clever Devices LTD where I provide senior leadership and direction for multi-million dollar public transit technology projects. In this demo, I'll teach you how to create a 3-node HA Docker Swarm cluster with a shared storage, container registry, and a reverse proxy. We'll also discuss some best practices for logs collection.

  • Using CI (Continuous Integration) to automate Linux sysadmin tasks

    In this meetup, I'm going to talk about using CI (Continuous Integration) tools to automate the deployment of sites and applications into production servers. To this end, I'm going to show off using gitlabci runners to build and deploy both a jekyll website, and a ruby application, as well as leveraging docker for the builds. Everyone should be able to leave with the knowledge of: - Install and configure docker engine - Install and configure gitlab ci runners in docker and shell execution modes. - Leverage artifacts between stages to automate distribution of files - Automate deployments to sites into production Extra Details: Our office building may require assistance for wheelchair accessibility.

  • Encrypt your life - a holiday gift!

    Encryption has been a hot topic for years in the tech community and is now heating up in the general public.

This meet up is geared towards beginner to intermediate. If you are advanced, please come as well and bring your friends/family that want to learn. We can always use another short speaker, too.

  • The Fairwinds Game Experience

    AOL / Advertising.com

    Combo meetup brought to you by Baltimore Gamer and Charm City Linux for a different kind of meetup night! We will hear about the creation of AND play the Fairwinds Game. This is an interactive session that does require some knowledge beforehand and computer if you would like to play the game (see instructions below). We will hear from Berend Tober, Fairwinds Game creator, who has been a PostgreSQL user for over 15 years. His experience includes both private industry and federal government roles in systems modeling, network administration, software development and data base management. Agenda: 6pm - Berend will come early to answer any questions about the material or resolve system connectivity issues. Come early if you didn't get a chance to read any of the material a head of time. 6:45pm - overview of the application and discuss some design and architecture issues underlying its development. 7:15pm - game play. Bring your laptop with internet connectivity and the psql client (instructions in the link below) **Must have basic SQL and linux command-line experience** You will want to read the "Fairwinds Overview", "Fairwinds Tutorial" and "Fairwinds SQL Pasteables" reference pages in advance available at https://github.com/bmtober/fairwinds. These documents explain how to connect to a Postgresql data base, basic use of the psql client software, and will prepare you to be a competitive player. 'Fairwinds' is a multi-player on-line, command-line interface game that involves real-time, competitive trading on five simulated markets. Players interact with the game by using either the Postgresql psql client to enter basic SQL commands or an interactive menu system. Note that the presentation is not simply a repeat of the tutorial. The talk will fill in and expand upon what you learn from the tutorial, so advance review is highly encouraged.

    Home Automation with F/LOSS If you're like me, you want to live in the home of the future where automation treats you like royalty. And, if you're like me, you can't stand the idea of running something so important as your home with proprietary software. This talk will overview the current landscape of home-automation technology, see where free software can come in to it, and go over the basics of automating your own home. Bio David Lachut is a PhD Candidate in Computer Science at the Univeristy of Maryland, Baltimore County. His research combines home automation and data analysis to build residential energy management systems. His first linux distro was Ubuntu 7.10, Gutsy Gibbon, but now he spends most of his time with Debian Testing. His secret ambition is to live on the starship Enterprise, or at least to do his part to invent the Enterprise's computer. Parking is free around the Natty Boh campus except on a small park of Conkling where it is pay to park.
