An introduction to Dapr. And we took a picture of the group:

a couple of weeks ago I was trying to deploy MongoDB in AKS using the MongoDB Enterprise Operator and had trouble finding a simple tutorial to make the thing work. This post intends to fill that gap with a straight to the point approach. Prerequisites # Be sure to deploy AKS with a set of nodes with at least 8GB of RAM. I used Standard_D3_v2

So you are new to Dapr and you are trying to understand how it works with you .NET Core application. You already tried launching your app with the Dapr CLI and then you find yourself wondering on how to debug the mix with Visual Studio Code. Well, follow this simple steps and you’ll be ready:

A common challenge when building cloud applications is how to manage the credentials in your code for authenticating to cloud services. In this session we’ll explore how to keep your credentials safe and how you can work without saving those credentials in the developers machines and therefore avoid an accidental upload to source control.

What if I tell you that it’s possible to connect you AKS pods to an Azure Key Vault using identities but without having to use credentials in an explicit way? Well with AAD Pod Identities you can enable your Kubernetes applications to access Azure cloud resources securely using Azure Active Directory (AAD) including Azure Key Vault.

Durante el mes de Octubre tuve la suerte de grabar en LinkedIn Learning mi primer curso online sobre Kubernetes. Aun me queda mucho por aprender y mejorar en este formato, ya que mientras grabas los cursos no recibes feedback inmediato como sí ocurre cuando das una charla o haces una presentación.

Recently I learned about GitOps which is a way to manage your Kubernetes clusters and the applications you run on top using Git. The idea is that you can declaratively describe the desired state of your systems in Git and roll out changes as soon as merges occur. You can immediately see the main benefits of such an approach: Your Git repositories become the single source of truth for both your infrastructure and application code, allowing the teams to increase productivity and stability (you get the Git log to audit changes).

Two weeks ago I got an email message from Microsoft Azure explaining that Azure Kubernetes Services had been patched but that I had to restart my nodes (reboot the clusters) to complete the operation. The first thing you need to know is that, when things like this happens, the Azure platform creates a file called /var/run/reboot-required in each of the nodes of your cluster.

After collaborating with the Azure Ansible container I decided to also develop a Developer Container for those who want or need to use the Azure Blockchain Development Kit for Ethereum to create smart contracts, taking away the burden of installing Python, Truffle, Ganache and NodeJS on your machine. Once again I collaborated with Chuck Lantz and the container definition resulted in the following two files:

Last year I was working on a project for deploying Azure services using Ansible, and let me tell you something: Back then a feature like Visual Studio Remote Containers would have helped us so much! Why? Because just installing Visual Studio Code, the Remote Development Extension Pack, and Docker you have a killer combo that makes it possible to create a Development environment in a snap and share it with your source code.

Recently I had to update a bunch of Log Analytics Workspaces resources to enable the Container Monitoring Solution. So I came up with this ARM Template that I want to share with you: { "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#", "contentVersion": "1.0.0.0", "parameters": { "LogAnalyticsWorkspaceName": { "type": "string", "metadata": { "description": "Log Analytics Workspace name" } } }, "variables": { "workspaceResourceId": "[resourceId('Microsoft.OperationalInsights/workspaces/', parameters('LogAnalyticsWorkspaceName'))]", "containerSolutionName": "[concat(parameters('LogAnalyticsWorkspaceName'), '-containers')]" }, "resources": [ { "type": "Microsoft.OperationsManagement/solutions", "apiVersion": "2015-11-01-preview", "name": "[variables('containerSolutionName')]", "location": "[resourceGroup().location]", "plan": { "name": "[variables('containerSolutionName')]", "product": "[concat('OMSGallery/', 'ContainerInsights')]", "promotionCode": "", "publisher": "Microsoft" }, "properties": { "workspaceResourceId": "[variables('workspaceResourceId')]" } } ], "outputs": {} } Hope it helps!
