Azure Storage Explorer Emulator for Developers
Azurite open source Azure Storage API compatible server (emulator)
Azurite is an open source Azure Storage API compatible server (emulator). Based on Node.js, Azurite provides cross platform experiences for customers wanting to try Azure Storage easily in a local environment. Azurite simulates most of the commands supported by Azure Storage with minimal dependencies.
Azurite V2 is manually created with pure JavaScript, popular and active as an open source project. However, Azure Storage APIs are growing and keeping updating, manually keeping Azurite up to date is not efficient and prone to bugs. JavaScript also lacks strong type validation which prevents easy collaboration.
Compared to V2, Azurite V3 implements a new architecture leveraging code generated by a TypeScript Server Code Generator we created. The generator uses the same swagger (modified) used by the new Azure Storage SDKs. This reduces manual effort and facilitates better code alignment with storage APIs.
3.0.0-preview is the first release version using Azurite’s new architecture.
Features & Key Changes in Azurite V3
Blob storage features align with Azure Storage API version 2020-04-08 (Refer to support matrix section below)
Queue storage features align with Azure Storage API version 2020-04-08 (Refer to support matrix section below)
SharedKey/Account SAS/Service SAS
Get/Set Queue Service Properties
Preflight Request
Create/List/Delete Queues
Put/Get/Peek/Updata/Deleta/Clear Messages
Features NEW on V3
Built with TypeScript and ECMA native promise and async features
New architecture based on TypeScript server generator. Leverage auto generated protocol layer, models, serializer, deserializer and handler interfaces from REST API swagger
Microsoft Azure Storage Explorer tool can make your life easier to do your Azure Storage Management. Copy – Paste data is a Great and handy feature for Administrators.
Hope this is useful and go try it yourself.
Working with Dapr in WSL2 Remote VSCode and Ubuntu 20.04 distro
Dapr is a portable, event-driven runtime that makes it easy for any developer to build resilient, stateless and stateful applications that run on the cloud and edge and embraces the diversity of languages and developer frameworks.
Developer language SDKs and frameworks
To make using Dapr more natural for different languages, it also includes language specific SDKs for Go, Java, JavaScript, .NET and Python. These SDKs expose the functionality in the Dapr building blocks, such as saving state, publishing an event or creating an actor, through a typed, language API rather than calling the http/gRPC API. This enables you to write a combination of stateless and stateful functions and actors all in the language of their choice. And because these SDKs share the Dapr runtime, you get cross-language actor and functions support.
I’m using Windows Insider Build version 21277-RS with Docker for Windows Edge and Visual Studio Code.
Docker for Windows Edge Version Running.
Because Docker for Windows Edge support WSL2 Engine and Visual Studio Code too, brought me to an idea to build dapr into Ubuntu 20.04 WSL Distro on my Windows Insiders 21277 RS version on my Surface Book 3. There for you must activate the WSL2 integration with my default WSL distro Ubuntu-20.04.
Dapr init ( in the Ubuntu-20.04 WSL2 Linux distro )
Here you find the Dapr dev environment installation types for Dapr init, I did the standalone version. Dapr makes then the following containers :
Dapr Containers.
Then we have the following running :
Dapr Dashboard
Zipkin
Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in service architectures. Features include both the collection and lookup of this data.
Zipkin Traces
Dapr Dashboard
Now we have Dapr running in the WSL2 Ubuntu-20.04 distro, you can use Visual Studio Code on Windows Insiders using Remote WSL and work with your favourite dapr SDK like the list above 😉
From here you can work with your dapr application.
In this guide dapr is running with Docker containers, but you can also install it on Kubernetes or K8s, AKS, Azure any where, see this overview :
Dapr with Kubenetes Containers.
Dapr Overview.
Important Note : Dapr is now production ready with version 1.0 ! Developers, DevOps, AzOps, you can start with it and Build and Test your own microservices and Container apps ! Hope you are having fun with it too 😉
Start Creating Azure Kubernetes Cluster for your Containers.
Managed Azure Kubernetes Service (AKS) makes deploying and managing containerized applications easy. It offers serverless Kubernetes, an integrated continuous integration and continuous delivery (CI/CD) experience, and enterprise-grade security and governance. As a hosted Kubernetes service, Azure handles critical tasks like health monitoring and maintenance for you. The Kubernetes masters are managed by Azure. You only manage and maintain the agent nodes. As a managed Kubernetes service, AKS is free – you only pay for the agent nodes within your clusters, not for the masters. In the following steps you can see the different ways for creating Azure Kubernetes Cluster via the Azure Portal, or via Azure Cloud Shell, or via Azure Resource Template. When the Microsoft Azure Kubernetes Cluster is running, then I will explain the different ways for deploying container workloads on AKS. When your workload is running on Azure Kubernetes Services, you also have to monitor your Container workloads with Azure Monitor Container Insights to keep in Controle. Let’s start with installing Azure Kubernetes Services (AKS)
Installing Azure Kubernetes Cluster via the Portal.
To begin you need of course a Microsoft Azure Subscription and you can start for free here
Basics information of the Azure Kubernetes Cluster
To Create the Azure Kubernetes Cluster, you have to follow these steps and type the right information in the Portal:
Basics
Scale
Authentication
Networking
Monitoring
Tags
Review + Create
At the basics screen you select the right Azure Subscription and the Resource Group. You can create a New Resource Group or one you already made.
At Cluster details, you give your Cluster a name and select the Kubernetes version.
Here you select the Kubernetes Node size for your Container workload and the number of nodes.
You can start a Cluster already with One node, but choose to start with the right size for your workloads.
When you click on Change size, you can choose your nodes to do the job. 😉
Select the right Size node
Then we go to step 2 and that is Scale.
2. Scale options in Azure Kubernetes Cluster
Here you have two options :
Virtual Nodes
VM Scale sets (Preview)
To quickly deploy workloads in an Azure Kubernetes Service (AKS) cluster, you can use virtual nodes. With virtual nodes, you have fast provisioning of pods, and only pay per second for their execution time. In a scaling scenario, you don’t need to wait for the Kubernetes cluster autoscaler to deploy VM compute nodes to run the additional pods. Virtual nodes are only supported with Linux pods and nodes. More information here about Virtual Nodes
To create an AKS cluster that can use multiple node pools, first enable two feature flags on your subscription. Multi-node pool clusters use a virtual machine scale set (VMSS) to manage the deployment and configuration of the Kubernetes nodes. With this Preview feature you can run Linux Containers and Windows Containers on the same Cluster. More information here about VM Scale sets (Preview)
3, Authentication
The service principal is needed to dynamically create and manage other Azure resources such as an Azure load balancer or container registry (ACR). To interact with Azure APIs, an AKS cluster requires an Azure Active Directory (AD) service principal. More information about the Service Principal can be found here
Azure Kubernetes Service (AKS) can be configured to use Azure Active Directory (Azure AD) for user authentication. In this configuration, you can sign in to an AKS cluster by using your Azure AD authentication token.
Cluster administrators can configure Kubernetes role-based access control (RBAC) based on a user’s identity or directory group membership. More information about RBAC for AKS
4. Networking
Configuring the virtual Networks for your Azure Kubernetes Cluster is important for the right IP range but later on also for the Network Security Groups (NSG).
Here you see an example of the Kubernetes NSG which is connected to the Internet by Default after installation, you can deep dive into security but be careful which settings you do here because Microsoft resources must have access to service the Azure Kubernetes Cluster.
NSG created after installation is finished
NSG Rule set Inbound and outbound
In a container-based microservices approach to application development, application components must work together to process their tasks. Kubernetes provides various resources that enable this application communication. You can connect to and expose applications internally or externally. To build highly available applications, you can load balance your applications. More complex applications may require configuration of ingress traffic for SSL/TLS termination or routing of multiple components. For security reasons, you may also need to restrict the flow of network traffic into or between pods and nodes.
Best practices for network connectivity and security in Azure Kubernetes Service (AKS):
Keep Azure Monitoring Enabled and Connect to your Log Analytics workspace or create a new workspace for Container monitoring of your Azure Kubernetes Cluster.
Azure Monitor for containers is a feature designed to monitor the performance of container workloads deployed to either Azure Container Instances or managed Kubernetes clusters hosted on Azure Kubernetes Service (AKS). Monitoring your containers is critical, especially when you’re running a production cluster, at scale, with multiple applications.
Azure Monitor for containers gives you performance visibility by collecting memory and processor metrics from controllers, nodes, and containers that are available in Kubernetes through the Metrics API. Container logs are also collected. After you enable monitoring from Kubernetes clusters, metrics and logs are automatically collected for you through a containerized version of the Log Analytics agent for Linux. Metrics are written to the metrics store and log data is written to the logs store associated with your Log Analytics workspace.
6. Tags
When you build more Azure Kubernetes Clusters for different departments or teams you can TAG your Clusters for organizing your billing and security for example. Here you find more information about tagging.
After this you click on the last step Review and Create The Azure portal will do a validation of your Azure Kubernetes Cluster settings, and when it’s validated you hit Create. But when you want more Automation, you can download the JSON ARM template first and use that.
Installing Azure Kubernetes Cluster via Cloud Shell
Azure Cloud Shell AKS CLI
Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. Cloud Shell lets you use either bash or PowerShell to work with Azure services. You can use the Cloud Shell pre-installed commands to run the code in this article without having to install anything on your local environment.
Here you see an Example of AKS CLI with Auto Scaler with max count of nodes 😉
Installing Azure Kubernetes Cluster via Template
Create Azure Kubernetes Cluster via Template in the Portal
Now you have your Microsoft Azure Kubernetes Cluster (AKS) running in the Cloud, you want to deploy your Container workloads on the Cluster. In the following steps you see different deployments.
Deploy Container workload with Azure DevOps Project
Deployment Center
First you select your repository where your source code is of your workload.
Set the information right and click Next.
Simple example Click Next
Create a Container Registry.
Building Pipeline with Azure DevOps.
Here you see the Building in Microsoft Azure DevOps.
Build, test, and deploy in any language, to any cloud—or on-premises. Run in parallel on Linux, macOS, and Windows, and deploy containers to individual hosts or Kubernetes.
Here you find all the information about Microsoft Azure DevOpsfor your workloads, code and Deployments.
Deploying Container workload completed with Azure DevOps.
Deploy Container Workloads via Visual Studio Code
When you download and install Visual Studio Code on your computer, you can install the Azure Kubernetes extension for VSCode.
Here you see Microsoft Visual Studio Code connected with my Azure subscription where my Azure Kubernetes Cluster is running. With the standard Helm Repository packages for deployment to your AKS Cluster. Here you see a WordPress yaml file which I deployed to the Kubernetes Cluster on Azure.
Just Select your Package and Install on Azure Kubernetes.
From here you can into the Container and read the logs.
I’m using Visual Studio Code a lot for Azure Kubernetes but also for Docker Containers and images.
Making Azure ARM JSON templates and this great for Infrastructure as Code.
Azure Monitoring with Container Insights
In One Dashboard you can see the Status of all your Clusters
Azure Monitor Container Insights Live View
Because we installed Azure Monitor for Containers on the Microsoft Azure Kubernetes Cluster, we can live see what is happening inside the Kubernetes Cluster with the containers. This is a great feature when you have a issue with a Container for troubleshooting fast and see what is happening.
Conclusion
Microsoft Azure Kubernetes Cluster is fast and easy to manage. You can upgrade your Cluster without downtime of your Container workload. With Azure Monitor for Containers you can see what’s happening inside the container and you can set alerts when something went wrong. This keeps you in Controle of the solution. With Deployment center alias Azure DevOps Projects you can deploy your workload via Azure DevOps Pipeline and work on versioning, testplans, Azure DevOps repo and work together with a Team on the following releases. Working with Azure Kubernetes Multi node pools with Linux and Windows on the same Cluster is possible. Try it yourself and start with a Proof of Concept for your Business.
