Troubleshooting ERROR: The subscription is not registered to use namespace ‘Microsoft.ContainerInstance’.

While trying to create the Azure Container Instances on one of the newly created Azure Subscription, we came across this strange error, “ERROR: The subscription is not registered to use namespace ‘Microsoft.ContainerInstance'”. So we checked our configuration and the way we were creating the Azure Containers, and it all seemed okay. So we dig a little around by using PowerShell, authenticate to Azure using Login-AzureRmAccount and fire few commands.

The first command we fired was classic Get-Command to check if there are any existing cmdlets to help with Azure Resources and sure enough, there it was:

Remove old docker images from Azure Container Registry

As part of the Continuous Integration process, new builds are generated which contains certain enhancements or modification or bugfixes. For a containerized application deployment, docker images are created as part of builds which then needs to be uploaded to one of the container registries. Over the time, the registry will get filled up. Also as one use more and more space on the container registry, one needs to pay more and more.

There are no inbuilt commands or utilities provided by Docker for this. You have to write complex scripts for doing it. Fortunately, in latest round of the Azure CLI update, Microsoft has added some commands to do this. However, it can be cumbersome to select and remove docker images one at a time.  Continue reading “Remove old docker images from Azure Container Registry”

Updated: Microsoft VSTS converted to Azure DevOps

Visual Studio Team Services (VSTS), Microsoft’s application lifecycle management system, is to undergo a major shake-up and rebranding. Instead of a single Visual Studio-branded service, it’s being split into five separate Azure-branded services, under the banner Azure DevOps.

The five components:

  1. Azure Pipelines, a continuous integration, testing, and deployment system that can connect to any Git repository
  2. Azure Boards, a work tracking system with Kanban boards, dashboards, reporting

Deploy ASP.NET Core App as Azure Containers Instances (ACI)

Microsoft has invested billions in Azure to drive technology and also hired best of the minds on this planet. From last few months, Azure has been launching new container-focused products and services on a regular basis. One of these products is Azure Container Instances. It acts as a bridge between platform as a service and infrastructure as a service architecture. Perhaps it would be okay to call this service as “Container as a Service”. Azure Container Instances (ACI) allows to rapidly create and launch containerized applications, without any overhead and with an easily scriptable set of commands. Designed to work Continue reading “Deploy ASP.NET Core App as Azure Containers Instances (ACI)”

Build ASP.NET Core Web App and deploy as Azure Web App on Containers

Azure Web Apps or Azure App Service Web Apps or simply Azure Websites is a PaaS service from Microsoft Azure which can be used to host web apps or APIs build using a variety of programming languages like ASP.NET, ASP.NET Core, Java, Ruby, PHP etc. It is also optimized for hosting web applications and containers, in case the SDK version required is not already supported by Web Apps. Rather than using ACS (Azure Container Services) and AKS (Azure Kubernetes Service), Azure Web Apps are more suitable for deploying long running containers. Also they become more affordable in terms of pricing as compared to the ACS and AKS. In this post, we’ll discuss how to create a very basic ASP.NET Core App and then deploy it as a container on Azure Web App.  Continue reading “Build ASP.NET Core Web App and deploy as Azure Web App on Containers”
