Web Assembly aka WASM is currently gaining a lot of attention into the container community - for legit reasons! WASM is a web-optimized code format that significantly improve web application performances running on browsers. However, it is gaining more and more attention in the container world lately, because of its sandbox/isolation hence - safety, near-native… Continue reading Exploring WASM, WASI with .net7 & Docker

Elastic self-hosted pool for Azure DevOps (on Kubernetes)
UpdateThere is a follow up post with some updates, you can read here. Introduction If you are using Azure Pipelines, then you surely have used Microsoft-hosted agent. With Microsoft-hosted agents, maintenance and upgrades are taken care of for you. However, there are times when self-hosted agents are needed (i.e. customized images, network connectivity requirements etc.).… Continue reading Elastic self-hosted pool for Azure DevOps (on Kubernetes)
Bridge to Kubernetes – be confident on shipping software
Bridge to Kubernetes is a successor of Azure Dev Space. Distributed software’s are comprised of more than one services (often referred as micro-services), they depend on each other (one service invoking APIs of another service) to deliver capabilities to end users. While separations of services bring flexibility in delivering features (or bug fixes) faster, it… Continue reading Bridge to Kubernetes – be confident on shipping software
Manage Kubernetes running anywhere via Azure Arc
Azure Arc (currently in preview) allows attach and configure Kubernetes Clusters running anywhere (inside or outside of Azure). Once connected the clusters shows up in Azure portal and allows applying tags, policies like other resources. This brings simplicity and uniformity managing both cloud and on-premises resources in a single management pane (Azure Portal). Azure Arc… Continue reading Manage Kubernetes running anywhere via Azure Arc
Restricting Unverified Kubernetes Content with Docker Content Trust
Docker Content Trust (DCT) provides the ability to use digital signatures for data sent to and received from remote Docker registries. These signatures allow client-side or runtime verification of the integrity and publisher of specific image tags. Image source: Docker Content Trust Through DCT, image publishers can sign their images and image consumers can ensure… Continue reading Restricting Unverified Kubernetes Content with Docker Content Trust
Azure AD Pod Identity – password-less app-containers in AKS
Background I like Azure Managed Identity since its advent. The concept behind Managed Identity is clever, and it adds observable value to any DevOps team. All concerns with password configurations in multiple places, life cycle management of secrets, certificates, and rotation policies suddenly irrelevant (OK, most of the cases).Leveraging managed identity for application hosted in… Continue reading Azure AD Pod Identity – password-less app-containers in AKS
Azure AD App via ARM Template Deployment Scripts
Background ARM templates offer a great way to define resources and deploy them. However, ARM templates didn’t have any support to invoke or run scripts. If we wanted to carry out some operations as part of the deployment (Azure AD app registrations, Certificate generations, copy data to/from another system etc.) we had to create pre… Continue reading Azure AD App via ARM Template Deployment Scripts
Terraforming Azure DevOps
Background In many organizations, specially in large enterprises there’s a need to automate Azure DevOps projects and Teams members. Manually managing large number of Azure DevOps projects, Teams for these projects and users to the teams, on-boarding and off-boarding team members are not trivial. Besides managing the users sometimes, we just need to have an… Continue reading Terraforming Azure DevOps
Inter-process communication on Windows Containers
Background Legacy monolith applications that are built to run on single beefy server can take advantage of containers to simplify the deployment model and also potentially opens possibility to re-architect piece by piece without triggering a complete rewrite. I ran into a scenario where I am considering wrap up a large monolith (with many threads… Continue reading Inter-process communication on Windows Containers
Linkerd in Azure Kubernetes Service cluster
In this article I would document my journey on setting up Linkerd Service Mesh on Azure Kubernetes service. Background I have a tiny Kubernetes cluster. I run some workload there, some are useful, others are just try-out, fun stuffs. I have few services that need to talk to each other. I do not have a… Continue reading Linkerd in Azure Kubernetes Service cluster
