Understand Pods in Kubernetes

December 17, 2020

kubernetes pods Pods are the smallest deployable units of computing that you can create and manage in Kubernetes.

A Pod contains one or more containers. Containers are grouped into Pods so Kubernetes can provide services that are not supported in containers. For example, Pods provide shared storage/network resources, and a specification for how to run the containers. Docker is the most commonly known runtime, but it can be other types.

In short, Pods enable you to manage several tightly coupled application containers as a single unit.

Kubernetes can run Windows. So the command to manage Pods running Windows are the same as those running Linux. But you should know that you define Windows or Linux when you create the cluster.

In this article, you learn about how Pods work, how you can have multiple containers in a Pod, the lifecycle of a Pod, how Kubernetes handles networking with a Pod, and how to define a Pod using a PodTemplate in a Deployment, Job, or other Kubernetes resource.

Walkthrough on how to handle merge conflicts in Git

July 21, 2020

Git is distributed version control system designed to handle everything from small to very large projects with speed and efficiency.The foundation of DevOps, begins with using source code control. This includes the source control for your Infrastructure as Code.But sometimes, when you check in your code, either you or someone else has been working made a change that creates a conflict between branches.

When the same part of the same file in two branches have been changed, Git won’t be able to figure out which version to use. When such a situation occurs, Git stope your right before the merge commit, where you will need to resolve the conflicts manually.

In this walkthrough, you set up a new repository, make changes to the repository where so changes conflict with those on your local machine, merge the changes, and push the changes to the repository.

Cheatsheet and best practices for Git

July 16, 2020

Git is distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Git is a primary tool for both developers and cloud engineers who are moving to infrastructure as code. Git is the core of a modern version control software, which keeps track of every modification to the code in a special kind of database. If (dare I say “when”) a mistake is made, you can turn back the clock and compare earlier versions of the code to help fix the mistake while minimizing disruption to all team members.

You do not need to have your repository set up to get started with Git. Although you will want to set one up to save your changes and to manage your deployments. Learn more about how to set up your repositories in the previous post.

In this article, you will find a list of resources to use to learn how to get started with Git. The article provides some sample command in a pattern you will use for your code or your infrastructure as a code. There are also references on how to get started learning Git.

Or .. if you prefer you can use the Git Cheatsheet from GitHub. The contribution made in this blog post is to show you common patterns you will use daily.

Set up Git with repository on GitHub or Azure DevOps Repos

July 14, 2020

github
In setting up our production environments, we’re started to get some code that we will want to backup, save, reuse, make changes, and share with others. We will want collaborate. And a source control system is idea for all this.

Git is distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Git is a primary tool for both developers and cloud engineers who are moving to infrastructure as code. In our next post you will learn more about Git workflows. But first, because our blog is related to enterprise production, you will you will want to set up a repository for your code.

The purpose of this article is to provide the steps to get set up and provide the steps for some common scenarios for both GitHub and Azure DevOps so you can get started checking in code.

Walkthrough using Azure Policy to audit and enforce compliance

July 9, 2020

azpolicy Use Azure Policy to manage and enforce your standards for governance and compliance and to assess that compliance at scale. When you implement Azure Policy, you are effectively adding guard-rails for your users. But you also have a way to audit your organization compliance against a particular policy.

In this walkthrough, you will learn the implications of using a Policy in Azure. For this walkthrough, you will use Azure CLI to create a storage account that will not be compliant, but allowing its contents to be accessed using HTTP. Then you will add a Policy that requires HTTPS, and see how you can audit existing, non-compliant resource. You will audit the resource using the portal and using PowerShell script. Then you will create another non-compliant resource and see how Azure blocks the resource during creation.

Setting up Management Group for production in enterprise

June 29, 2020

org1 Once you have set up your first subscription, you can set up your Management Group.

In Azure, management groups are a way to group your subscriptions. When you apply policies and governance to your management group, all of the subscriptions within a management group automatically inherit the conditions applied. Enterprises want management groups as a way to scale your operations no matter how many subscriptions you may have.

For example, you may want to restrict the regions available for your resources to those within a particular region. A policy that reflects that can be applied to a management group and will automatically be applied to all management groups, all subscriptions, and all resources under that management group.

Organize Azure resources using management group, tags, naming convention

June 10, 2020

org1 Once you have set up your Azure administrators, you can begin to consider how to organize your cloud into management groups, subscriptions, resource groups. You will want to develop a naming standard, and way to tag resources.

Although you may be focused initially on just getting your resources deployed, you will want to be able to manage them. For example, a year from now you may want to know who is responsible for the virtual machine that is no longer doing anything, but is costing money. In other words, you may want lifecycle management.

You may want the ability to charge a set of resources to a cost center and to budget those resources. For example, you may want to receive alerts for both the users and for your administrators when costs are out of line with expectations.

And as we all know, it is easier to organize as you go. In this article, you will learn about some key points in organizing your Azure resources.
