Co-hosting 2 sessions in the Azure Hybrid Cloud Study Hall Series

I am very excited to be a part of a new Microsoft Azure Hybrid Cloud Study Hall series. This is a free fourteen-part weekly series that starts in April running through June.

In this study hall, you will learn how you can manage your on-premises, edge, and multi-cloud resources, and how you can deploy Azure services anywhere with Azure Arc and Azure Stack.

In this series, each session covers working with hybrid cloud resources using Azure services and hybrid cloud technologies. In these sessions we will:

  • Answer your questions live
  • Walk-through how to configure hybrid cloud resources
  • Walk-through how to deploy hybrid cloud resources
  • Walk-through how to manage hybrid cloud resources

In these sessions, together with you, we will work through Microsoft Learn modules focused on Azure Arc and Azure Stack HCI.

We have a solid lineup of speakers from Microsoft and the community! And I will be co-delivering two sessions myself.

Speaking at MMS 2022 in Person!

MMSMOA is back in person for 2022. I am excited to be heading back to present a session and be on some panels!

Here is the MMS website: https://mmsmoa.com

My session will be with my friend and co-author of my latest book John Joyner.

Here are the session details:

Azure Arc: Extending Hyperscale Cloud Management to Your Datacenter

Description:

Learn about Microsoft’s Azure Arc service, a new multi-cloud management platform that belongs in every cloud or DevOps estate. The premise of Azure Arc is compelling: why not extend familiar management tools proven in Azure to on-premise and other cloud networks? A practical scenario-based tour will get you up to speed quickly, with instruction and demos that are heavy with hands-on experience. If your organization has resources across the hybrid cloud, multi-cloud, and edge environments, then this session is for you. You will learn how to configure and use Azure Arc to uniformly manage workloads across all of these environments.

What you will learn:

  • Introduces the basics of hybrid, multi-cloud, and edge computing and how Azure Arc fits into that IT strategy
  • Insights into Azure native management tooling for managing on-premises servers and extending to other clouds
  • Detail an end-to-end hybrid server monitoring scenario leveraging Azure Monitor and/or Microsoft Sentinel that is seamlessly delivered by Azure Arc
  • Define a blueprint to achieve regulatory compliance with industry standards using Azure Arc, delivering Azure Policy from Microsoft Defender for Cloud

Dok Talks #121 – Running Stateful Apps in Kubernetes Made Simple

I am giving a talk for the Data on Kubernetes Community (DoKC) Community next week. They are a user group like community that focuses on how to build and operate data-centric applications on Kubernetes. Be sure to check them out! The DoK website is: https://dok.community.

My talk is titled: “Running Stateful Apps in Kubernetes Made Simple

ABSTRACT OF THE TALK

Eventually, the time will come to run a stateful app in Kubernetes. This can be a scary thing adding more moving parts to a Kubernetes cluster and deploying as well as managing your app on Kubernetes when it requires state.

In this talk, Steve Buchanan will take you through a journey of understanding how storage works in Kubernetes, how to Persistent state with pods, what storage options are available with Azure Kubernetes Service, best practices, and a demo of deploying a stateful app to AKS.

In the demo, I will show how to deploy stateful Worpress & Jenkins workloads on Azure Kubernetes Service using the GitOps model with Argo CD.

KEY TAKE-AWAYS FROM THE TALK

Overview of Storage in Kubernetes covering Storage Classes, Persistent Volumes, & Persistent Volume Claims. Overview of Azure Storage, Best Practices to running stateful apps in Kubernetes.

Cloudbusting Podcast Guest EP130 – Diving into Jucy Lucy, & Root Canal’s with a little Kubernetes, Azure Arc, & GitOps on the side

This was a fun podcast with Jez Ward, and Dave Chapman of Cloudreach. They run a podcast called Cloudbusting. On the podcast they focus on transformation, leadership, ways of working and emerging technology they explore the significant impact that cloud is having on people and businesses.

On this podcast episode, we set out to answer very important questions such as what are Jucy Lucy’s?, what are root Canals like today? oh, and yeah we also spend some time talking about what Containers, Kubernetes, & GitOps are and how they fit in the cloud.

Registering an Azure Kubernetes Service Cluster with Argo CD

Argo CD is a GitOps operator and the goal of it is to be able to deploy apps to Kubernetes. In the majority of cases, we want to use Argo CD to deploy apps to many clusters.

Argo CD itself is deployed as a set of pods on a Kubernetes cluster. By default with an Argo CD deployment, the cluster it is running on is set as “in-cluster” (https://kubernetes.default.svc). When apps are configured for deployment a Kubernetes Cluster under Destination is required. They can be deployed to either the “in-cluster” K8s cluster or an external K8s cluster.

In order to deploy apps to an external Kubernetes cluster, you will need to register an external K8s cluster with Argo CD.

If you want to see the clusters you have registered with your Argo CD one way is through the web UI. Once you log in navigate to Settings and then Clusters to see them.

You can also see the clusters you have in the Argo CD CLI. To use the Argo CD CLI you need to log into the Argo CD API Server as shown in the following screenshot.

To see what clusters are registered from the CLI you can run

argocd cluster list

You will notice that you will only see the In-Cluster K8s cluster until you add an external one. Also, note that you are not able to register a new K8 cluster in the Argo CD web UI. You can only register a new K8s cluster from the Argo CD CLI. Within the Argo CD web UI you can delete the default in-cluster K8s cluster. This is not recommended.

If you click on the In-Cluster K8s cluster you can modify some settings of the in-cluster K8s cluster in the Argo CD web UI such as the name of it and its namespace. Not useful when you want to have more control over the settings around the K8s cluster you will be deploying apps to.

In my example, my Azure subscription has two AKS clusters. You can see this in the following screenshot. The arriving-gelding-k8s cluster is my In-Cluster object in Argo CD. The selected-worm-k8s is not my In-Cluster so I want to add this one to my Argo CD.

To add the new external cluster run use the following steps.

Step 1: Add your target K8s cluster to ArgoCD via the context in your kubectl config.

-For AKS you can simply log into your Azure subscription from VS Code on your computer and then run

 az aks get-credentials –resource-group RGNAME –name AKSCLUSTERNAME

This will add the context for your AKS cluster to your kubeconfig file.

-For the process on your setup refer to the following link as it may differ:  https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters

Step 2: List the K8 cluster contexts in your current kubeconfig file to ensure your target cluster has been added. Do this by locally running:

kubectl config get-contexts -o name

Step 3: Install a Service Account (argocd-manager), into the kube-system namespace of your kubeconfig file context:

argocd cluster add CONTEXTNAME

It will look like this:

After completing the previous steps you can run argocd cluster list again or go into the portal. You will see your new cluster added.

That wraps up this blog post. Now you should be able to deploy to more than just your In-Cluster Kubernetes cluster. Check back soon for more posts on Argo CD, GitOps, Kubernetes, and Azure topics.
