What is Docker? & Why you should use it.

If you’re a developer or work in IT, you’ve likely heard of Docker. It’s a  3 year old open source technology that has grown exponentially during its existence. And now, it’s beginning to turn heads in even the most regulated industries. First let’s explore what Docker actually is for those that are unfamiliar. “Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications,” according to the Docker website. The technology consists of two tools, the Docker Engine and the Docker Hub. The Docker Engine is a, “portable, lightweight runtime and packaging tool,” while Docker Hub is a, “cloud service for sharing applications and automating workflows.” The technology is particularly appealing for developers because it is now easier than ever to make sure you develop, test and deploy using the same environment as your colleagues, resulting in less issues caused by differences or missing libraries. Docker also offers developers the flexibility to quickly run their apps anywhere, whether its on laptops, VMs or QA servers. More simply put, “Docker helps developers build and ship higher-quality applications, faster.” Sysadmins are finding the technology useful as well, because of the ability to standardize development environments among other reasons. “Docker helps sysadmins deploy and run any app on any infrastructure, quickly and reliably.” Docker seems to be on the same disruption path as GitHUB, which shook the source control systems, or more lately, how composer “revolutionized” the way we deploy components of a PHP and Symfony application. On the business side, the benefits may be huge. By simplifying the way we deploy apps and creating more manageable...

A quick guide & understanding of GitHub

What is GitHub? Git is an open-source version control system very similar to other version control systems such as Subversion, CVS and Mercurial. What is it used for? When developers are coding, they are making constant changes to the code and releasing new version. Version control systems keep these revisions & store the modifications in a cloud repository allowing developers to easily collaborate, as they can download a new version of what they are building, make changes, and upload the newest revision. Every developer can see these new changes, download them, and contribute. Features in GitHub Let me go over a few of the basic features in GitHub to give you a basic understanding of  what each feature is and what it is used for. Repository A Repository is where all the files for a particular project are stored and provided by a unique link. Forking In GitHub you have the ability to grab another Git members project and create a new project , modifying the code and creating your own version or adding in new features Pull Request A Pull request is used for when you want copy the files however any changes will be notified to the original developer where they can choose to accept the changes or not. Compare Compare shows a list of all the commits unique to a branch, the sum of all the files changed across all of those commits, and a unified difference of all of those changes. It clearly summarizes what the branch represents. Basic Git Commands git clone  this command is used to upload your local directory files to your Git Project. git status  Used to show files that have not been...
