Hey friends,
Welcome to #AzureSpringClean, an initiative from Joe Carlyle and Thomas Thornton where Iām honored to be able to participate in again for the 4th year already. Thanks guys for trusting me once more for sharing some Azure knowledgeā¦
This time, I wanted to try and guide you through the buzzword of the last couple of years, containersā¦ and more specifically, what different options you have in Azure to run your containerized workloads.
Ever since I joined Microsoft (Sept 2019) and started working in the Azure Technical Trainer team, I deployed a demo Azure Kubernetes Service (AKS) with a few sample containers. Helping me in walking training attendees through the architecture, the management concepts and what it takes to run containerized workloads using the advanced capabilities coming with Kubernetes on Azure.
Knowing this AKS cluster got deployed about 20 months back, it also meant my setup was getting a little bit out-of-date. Interesting enough, it ran for almost 500 days (I considered waiting to publish this article to celebrate its anniversaryā¦)
Hi all,
Iāve deployed me an AKS - Azure Kubernetes Service environment that I use in my Azure training class deliveries almost every week (yes, every AZ-course touches on AKS and Containersā¦)
The Problem My AKS environment was running fine all this time (a bit over a year), allowing me to rely on existing deployed Kubernetes services, as well as building new services as a live demo. Until this morning, where all of a sudden, my own services didnāt start at all, but the kube-system services did. The error message I noticed for this service was ImagePullBackOff and ErrImagePull.
Hey there,
Iāve been doing quite a lot with Docker and the different Azure Container Services offerings like Azure Container Instance and Azure Kubernetes Services.
As you probably know, the starting point of a containerized application is the Dockerfile. Look at this like an instruction script, which tells Docker what needs to happen, in order to grab the application source code, compile it and produce the container image.
Besides the complexity of running containers by itself, I personally think writing a Dockerfile is equally difficult and complex. So I am more than happy to know that Visual Studio (2017 and 2019) comes with some interesting Container Tools. Aside from helping in debugging containerized workloads, providing some interaction with the Docker engine, it also helps in compiling a Dockerfile for you.
Hey there,
At the recent DockerCon (virtual) Conference, Docker announced a more tightened partnership with Microsoft, boosting the adoption and integration of Docker containers for Windows Server as well as Azure-running workloads. A first announcement involved a cool integration with Azure Container Instance (ACI), a low-level container runtime on Azure, allowing you to run a container without the typical complexity. While ACI has been around for 2 or more years already, it now becomes possible to manage and run your ACI-based containers directly from the Docker commandline.
Hi again,
In about every Azure training delivered the last few months, I am talking about Docker and Azure Kubernetes Services - AKS
Along these months, the amount of āsample PODSā I am running within the Kubernetes cluster was continuously growing, resulting in a less efficient demo scenario to show.
So cleaning up these running PODS was my 5 seconds action this Saturday morning. While not super hard, it actually took me a bit longer than 5 seconds (more like 10min :)), since I forgot a few ābasicsā on how Kubernetes is running PODS.
Hey there,
With the May update of Windows 10 (named Windows 2004 :) ) being available since this week, together with DockerCon virtual conference, I think it was the right time to (finally) migrate my current Docker Desktop in Hyper-V mode to the new WSL 2 (Windows Subsystem for Linux).
In short, the process was smooth, straight forward, and not having any real impact on my ādemo environmentā Iām using continuously during my Azure training workshops and public speaking gigs.
Iām excited about this next project that finally got live, thanks to a bit of quiet time during the Holidays. While it is not up to the full 100% of what I had in mind, I didnāt want to hold back the content any longer, since Azure is moving already that fastā¦
The original idea of this material was based on a workshop I created for Microsoft Internal (Azure Developer Series) in Sept 2018 as a contractor, which was a combination of slides, videos and lab guides. The workshop existed in both in-person and virtual delivery format. At that time, the sample application was rather basic. Early July 2019, I got asked to work on an update of the content, and extend it with Azure DevOps, which was well-adopted in the market already, but still unknown to a lot. Instead of just working on āupdatesā, I decided to start from scratch, and work towards a more ābusiness readyā application, using SimplCommerce, an Open Sourced E-commerce platform application, built in .NET / .NET Core, and supporting different database back-ends.
