From YouTube: An early look at OpenShift 3.3: Getting Started

Description

This video highlights how a customer obtains a consistent experience between various frameworks in OpenShift 3.3. He could easily switch between .NET, Node.js and Java.

The model to build, iterate and deploy was easy and familiar. Joe was also able to work directly from the web browser for ad-hoc templates and search docker hub for community images as well.

Hi, my name is to Speicher fifteen I'm, going to talk to you today, a bit about some of the upcoming features. An open shift. I'm gonna show them to you with the the open source community origin bits. What's coming on, one three release which will eventually make their way into Red Hat products open shift, dedicated container platform and online. Hopefully some things are subject to change the way I'm going to do this I'm with paying a couple scenarios as a couple.

A

Different personas are people so first I'm going to start out as this employee who's new to a team team's been working with Java nodejs have been playing around micro services, but I've come from a background of of dotnet and I want to get familiar with this open ship thing that they're playing with and I learned about.

A

Hey, there's this cool online developer preview, what you didn't sign up and easily get started so I'm gonna do that so I've logged on I'll say my name is: is Joe coder, so I'm gonna come up with my some playground. The to mess around with it was pretty simple: I'm gonna create a project, so there's all kinds of technologies I wanted to toy with I see you got some instant apps, some Java, some PHP Ruby. What?

A

If something that people are working, whether they're talking about no GIS and and so let me, let me see what they got for note. She is so cool, there's no GS for I'll just going to grab this, give it some name so I'll, say yeah! That's my web app! That sounds good I'll play around with the example they've given to me and okay. This sounds good. Let's just create this application.

A

Okay, so I see I can manage my app I can get some command line tools for now. I'm, just gonna play around with the online bits so through the web browser. So let me continue here.

A

Okay, great so I see some things are going on here, my web, app that I created it looks like the build is running so if I wanted to I, could click on that I see? There's logs here, love logs um Matt looks like it pulled down all the dependencies. It's already pushing the the image back up that it had been built. It looks like, and it's uh it's almost done so let me go back to your view and see what I've done.

A

Health checks sounds important, I'll check back on that later, but now I just want to get something going in my playground.

A

So no deployments have no group services. Ok, I, see yeah deployments now kicking off, because the build completed great I do remember that I wanted to connect the database to this, and then I mentioned they were manga was commonly used so come over here and I'll I'll pick a friend and say: hey, you know I'm new to the team. What do you recommend and no idly enough?

A

They just give me this big blob of JSON to play around with and say I can just import it and like I'm, not sure what that really means, but I can see here that I have a an import. Eml Jason I would have expected. It checked in the source control some point, but I won't get on my friend for that right now. So I'll flip over I'll take a look at what they gave me.

A

I've grabbed the database templates and well I'm glad he gave me that file, because I probably would have struggled a little bit typing all this in. Maybe there was something back here in this catalog, but I trust. My my new coworker I probably should use what they gave me.

A

Yeah probably want to apply it and just use the results of that template. So, okay parameters, typical developer, I, take all the defaults and come back overview.

A

Okay, cool, so I see my web apps been running builded completed a little bit ago and now I starting to see some metrics that are involved with this. So I might hand this out. That couple friends is my hack and I might want to make sure that there's some high availability. So if my application goes down and the time it takes to come back up that people weren't, you know experiencing any downtime. So let me go ahead and scale this up to have some backup services there so I see now my database is firing out.

A

Well, that's as good, so since I'm using this note just for an end to this back and I'm going ahead and group the service together. So let me do that over here. Grab the so that's nice! It it tight ease it up a bit. It allows me to see them together, link together as I think of them. Logically of how I use my node.js front-end to consume my DB back-end? Well, okay, so I, guess, I'm familiar with the platform now I would like to play around with a couple other things.

A

So one is like I know that technology better that I have but I didn't really look for dotnet well, I, see, there's some dot and that stuff here, that's that's cool.

A

Let's just give it a simple name: I'll try! The sample comes with it again, some guidance and, let's flip back over to the overview, to see. What's going on, I see it builds running already, I can jump over and see the logs I can follow the logs and oh yeah and I'm used to seeing all this where it's pulling the dependencies and now getting ready to perform the build. So this is this is familiar territory to me as well.

A

So all this is good, so don't only it was easy for me to get going with no Jazz I'm now able to use the technology that I'm familiar with the dotnet stuff and I can start playing around with this as well so good as that's gonna, along building I had a I'd skipped on the before and I was looking at this and I wasn't sure what deploying image was so I I remembered my previous job I used to use this other.

A

Docker image from dr. hub, but wait a minute. This is I'm. Looking for this, it's telling me that it's actually run there's a root user. That seems like that's pretty important, that I know about this and I don't want to cause any issues of my my new job here, so I'm gonna, just back out of here and I'll, probably go with just the ones that I've been told. I should use or have been approved for usage. So there you go.

A

You see I've easily been able to walk through this without much in the way of assistance figure out how I deploy an application I kind of both the the web front-end the database and also some other technology I'm familiar with in the dotnet leveraging direct access to dr.

A

hub, as well as access to raw files in the backend as well and again, I could say: I'm gonna, leverage, the same back-end database service and I could link it up to that service and now I have kind of consistent view of what my app is the front end, which is the dotnet MongoDB and the back end and have a clean console and how I view those settings, so that was Joe coder, getting started with openshift 3-3 upcoming release. So an early preview of those feature you.
