From YouTube: GitOps Series - The Process

Description

GitOps is the use of a git repository as a single source of truth for all infrastructure and application deployment code. In this video we will walk through the process of creating Epics of works, break them down into individual tasks, make the necessary code changes, collaborate with peers, approve the changes, then let the automation take over and deploy our changes into production.

A

Hello today I want to talk about git-ops and how gitlab enables get-ups first off.

A

What is get ups git-ops is the using a git repository as the single source of.

A

Truth for all infrastructure and application deployment code, automation.

A

Is used to take that code and deploy it in a stateful manner out to various.

A

Different clouds, for example, using terraform to provision kubernetes.

A

Clusters in any public, publicly available cloud and using helm and.

A

Kubernetes to deploy applications into those scrubber nettie's clusters, but.

A

Today, I want to focus on the process. How does that code get into the git.

A

Repository in the first place, well, it's produced by smart individuals and teams.

A

Who collaborate together to deploy that to create that code and then deploy it?.

A

Into production, for example, infrastructure teams create.

A

Infrastructure code that is then put into the git repository and.

A

Automatically deployed through terraform to the cloud providers, an application.

A

Development teams will create deployment code that will go into the git.

A

Repository into helman kubernetes and automatically be deployed to those.

A

Public kubernetes services collaboration is key to this entire process.

A

Infrastructure teams, development teams, even management project management,.

A

Security and business stakeholders all need to collaborate together to produce.

A

This code in a fast and efficient manner, let me walk you through an example today.

A

I've got my get-ups demo group and I've created an example. Epic called scale. The.

A

Cloud this example, epic, is meant to illustrate the process and tasks that.

A

Are needed to scale up our kubernetes clusters.

A

Because get-ups is a get centric deployment. What we want to do is first.

A

Define what the project is who's going to be involved in it? What information is.

A

Required what coding needs to happen? What changes need to happen to our.

A

Infrastructure is code that should be reviewed and then finally deploy it into.

A

Production so let's take a quick look so in front of me, I've opened up an epoch.

A

In my m4r group and I've just put some very simple goals in here, for example, we.

A

Want to prepare for growth and we need to expand out our cloud capacity. This is.

A

Just an example: I've also got a couple of tasks here that can be checked off as.

A

They're completed.

A

I've pre created three different issues: one for each cloud: four: to represent the.

A

The changes needed for each each environment, for example, to scale my.

A

Azure kubernetes service to 10 nodes. I've got an individual ticket, so this.

A

Epic breaks down work by individual processes and the smallest change.

A

Possible I've got another one for google and a third for amazon. You can see here.

A

That the issue for scaling the amazon cluster has already been completed, we'll.

A

Take a quick look at that. I can click into this and I can see that there was a.

A

Merge request created and it has already been merged and I've got the history of.

A

What happened here, I did this all myself, so no approvals were required. I approved.

A

I self approved, and I merged my code. If I want to see exactly what's changed, I.

A

Just click into the merge request, I can see all the tests that passed before I.

A

Merged it, and after it also what was changed in the comment. History.

A

And making a note that I approved and merged it myself.

A

If I go back and look at a different one, let's take a look at one that hasn't.

A

Been completed first now.

A

Let's take a look at google looks like I've got a work in progress here. Another.

A

Merge request has already been opened, I'm going to click into this and I'm.

A

Going to review this and see: ok, it's still a work in progress, so nothing's.

A

Been changed, I can see what the proposed changes are. I can see that my initial.

A

Note count is going from two to five and there's no comments in this system or.

A

There's excuse me: there's one there's one comment in the system that shows what terraform is reporting back, that that will be changed so in terms of.

A

Get-Ups, it isn't just about the code, it's about the collaboration and get lab.

A

Enables the collaboration everybody to be working on the same page, all teams.

A

Work out of the same tool and are able to see that this is still a work. In.

A

Progress what changes I'm proposing and can make.

A

Comments looks good.

A

Can also assign it to additional people.

A

Can mention addition, people in the comment in the comment.

A

Section tag those people and they'll. Let you get a notification, we can all work.

A

On the same page understanding what code is being changed when it's being changed and who's going to approve it in this case, I'm going to.

A

Self approve, so I'm going to resolve the work-in-progress status, I'm going to.

A

Delete the source, branch and click merge.

A

Now, when I go back to my epoch, which is primarily where stakeholders and.

A

Business stakeholders will view progress. You can see that this is closed and the.

A

Deployments currently underway.

A

Everybody's able to work to work from the same system and understand where.

A

Things are at whether you're an infrastructure or whether you're an application development. All changes follow the same process of defining the.

A

Body of work assigning to individuals collaborating with teammates and then.

A

Deploying that code and using the git repository is that single source of.

A

Truth. Thank you.
