Intro to Docker

Overview

Docker is a set of tools that provide a runtime for creating, managing and orchestrating containers. Docker provides the ability for developers, system admins, or hobbyists to provision a container that can be configured as similarly to a virtual machine without all of the resource intensity. This series introduces the usage of the Docker client to run containers, managing the Docker daemon, using Docker Machine for provisioning runtime environments for the Docker toolset, Docker Compose for orchestrating and managing multi-container applications, as well as Docker Swarm for distributing those containers across multiple nodes in a cluster of machines. Stay tuned to get started with Docker!
Intro to Docker Overview
In this episode, Daniel and Justin give a general overview of what to expect in the upcoming Intro to Docker series. They cover topics like who is the intended audience, what the scope of the series will cover, and what are some specific topics that will be addressed.

[SOUND]. In this segment we're gonna take a quick look at what you can expect from our upcoming Introduction to Docker series. Justin, could you do us the immense favor of giving us at least a general overview of what we can look forward to? So Docker is a new tool on the scene that has made, well, provisioning these environments that we need to use reproducibly, over and over and over again. Whether it be Red Hat, Linux, and it is standardized to Linux, but also applications contained within those environments. It just makes it really easy, makes it fast, makes it reproducible, and has an entire tool set that allows us to manage all of those differences Excellent, now obviously this is a type of cloud service I do believe. And we're gonna have different people wanting to come in take a look at, Docker that's very interesting, maybe that's applicable for what I'm doing. Which lends us to the question of who is the intended audience for this because it can't cover a wide scope, correct? So the intended audience, let me back up just for a moment. There are cloud components and it is used for provisioning cloud services that's kind of the push. But the actual Docker tool will reside on your local machines. so there's kind of a playoff there. Now, as far as intended audience, there is an assumption that you have basic knowledge of Bash or command line type interactions, and most of our focus will be in a Bash-like environment. And being able to install, download, and some understanding of basic Operating System configuration. Because that's the entire purpose of dockers, creating what's called a docker image that will then spin up containers that behave like very light weight VMs, instead of provisioning full scale VMs. So, you need to have a little bit of experience there, as far as Linux understanding and command line understanding. But that's about it. All right, well I guess that lands us to what are some of the specific topics that we'll cover. Just give our good audience there a taste of what's to come. Well a taste, it does vary. And sadly, Docker is one of those things where like this is pretty easy, this is pretty easy, and then it can really crank up at certain points. So what are we gonna cover? Well, how do I run a container? And this is assuming I've all ready got Docker installed. We're actually gonna talk about installing Docker on all three major Operation System environments, which has gotten a great deal easier in the recent times. But how do I run a container? How do I get an image? What is an image? And how is that related to a container? How can I build a custom image? When I build a custom image, how do I distribute that? If I want to deploy to a cloud service, or I want to save it somewhere, what do I do then? How can I use this to make very large kind of architectural decisions? I focus mostly on application development, because well, that's what I do. But there are other use cases, and then we take a look at some of the more advanced tools, such as machine compose and swarm. Then, they add on to the standard docker tool set to allow for a really scaling up and out. Awesome stuff. Now a lot of the series that we do here at ITProTV lend themselves to either being a technical skill, or a certification, or exam-based type of series. Which one of those categories would you say this falls under? So this is definitely a technical skill. This is for someone who wants to know, well I know a little bit about computers. I've been diving into some development, or even infrastructure management right? Maybe you're working with developers and they're like hey, I need this, maybe this is something you can pass off to them. Hey, if you need to simulate an Ubuntu environment for your application to run in, here's how you get this set up. It is definitely just about learning the basics there, getting things up and running and not about obtaining a certification. We do not cover the entire breadth of the Docker ecosphere. [LAUGH] So definitely, just an introduction there. All right, well Justin that sounds awesome. We do appreciate your input on this topic. We appreciate you guys. Hopefully if it sounds like something you're interested in, we'll see you in the upcoming series. [SOUND]
