Open the Docker Desktop menu by clicking the Docker icon in the Notifications area (or System tray): There are additional advantages in having a comprehensive healthcheck. If you're running an ASP.NET web app but you want to use the base Windows image and control all your dependencies, you can add the Web Server and ASP.NET features: There's a standard pattern for installing dependencies from the Internet - here's a simple example for downloading Node.js into your Docker image: The version of Node to download and the expected SHA-256 checksum are captured as environment variables with the ENV instruction. If you want to help test the latest improvements and features and can handle some occasional breakage, use the unstable version. It is now possible to run Docker containers on Windows 10 and Windows Server, leveraging Ubuntu as a hosting base. Docker Desktop delivers the speed, choice and security you need for designing and delivering containerized applications on your desktop. Install Docker Desktop on Windows Double-click Docker Desktop Installer.exe to run the installer. With Compose, you can create a YAML file to define the services and with a single command, can spin everything up or tear it all down. Docker Desktop for Windows is available for free and provides a development environment for building, shipping, and running dockerized apps. You can rely on the regular running of the healthcheck to keep your cache up-to date, so you could cache items for 25 seconds, knowing the healthcheck will run every 30 seconds and refresh them. Multi-stage Dockerfiles make your app entirely portable. Dockerfile The process could be running, but your app could be in a failed state - for a .NET Core app, the dotnet executable may be up but returning 503 to every request. Install tools. If you experience issues for which you do not find solutions in thisdocumentation, on Docker Desktop for Windows issues onGitHub, or the Docker Desktop for Windowsforum, we can help youtroubleshoot the log data. To test your application, run: Choose > Troubleshootfrom the menu. Provide an app name, such as win-container-demo and choose Windows for Operating System. $ docker run -p 49160:8080 -d /centos-node-helloworld.

First, let’s get the tools you would need in this walkthrough: Install Docker on your machine: for Mac, for Windows, or for Linux. Today we'll look at what it takes to build and run an ASP.NET 4.x WebForms app in a Windows container.  February 2020 |, Using Declarative Jenkins Pipelines Michael Friis added this simple but very useful check to the Microsoft SQL Server Express image: The command verifies that the SQL Server database engine is running, and is able to respond to a simple query. For macOS, you can download XQuartz, and for Windows, try VcXsrv. It also makes it easy to see what version is present in a running container, you can just check the environment variable. Interested in Docker? Healthchecks are also very useful if you have expiry-based caching in your app. When the first user request hits, the app is already running warm so there's no delay in sending the response. Consultant and trainer. Microsoft's images are usually updated at the same time as the Windows image, but official images may not be. Microsoft MVP | Docker Captain | Pluralsight Author, Site Reliability Engineering (SRE): The Big Picture, Monitoring Containerized Application Health with Docker, Handling Data and Stateful Applications in Docker, Managing Load Balancing and Scale in Docker Swarm Mode Clusters, Build a Lightweight Dev Rig for Running Windows Docker Containers, Dockerizing .NET Apps with Microsoft's Build Images on Docker Hub, tailing the IIS log files so they get exposed to Docker. Also, remember to have your X server allow remote connections. Instead, you build a new image with the latest patches and replace your running container. See this Stack Overflow question for more info.. Select Next: Docker to continue. The Dockerfile syntax is clean and simple, and you only need to learn a handful of instructions to build production-grade Docker images based on Windows Server Core or Nano Server. Create .NET Core app. Packaging your own app will be a simplified version of step 2. You can check out the app in our dockersamples GitHub repo.  March 2020 |, Monitoring Containerized Application Health with Docker The 1809-based Windows container base image is a Semi-Annual Channel (SAC) release and will reach end of life on May 12th, 2020. Docker works cross-platform and such supports execution on a Windows host, including Windows 10 (Pro or Enterprise). You'll only find that out by testing, but if you do find problems you can just switch to using Server Core. In order to receive your app information, use: $ docker ps $ docker logs As a result, in the example above, Docker mapped the 8080 port of the container to 49160. To support that, Microsoft release regular updates to the base images on Docker Hub, tagging them with a full version number (10.0.14393.693 is the current version). Begin by running an interactive container with docker run -it --rm microsoft/nanoserver powershell and set up your app manually. The main improvement you get from using the Docker engine is that you create images, which are like snapshots of your application, with all its dependencies. Multi-stage Dockerfiles make your app entirely portable. This makes Windows 10 a perfect development environment for Docker use-cases. With some poetic license, let’s loosely call a desktop application a graphical application: a software requiring a canvas to draw on its user interface. Remember that the Dockerfile will be the ultimate source of truth for how to deploy and run your application. They let us bake our existing applications into Docker images and deploy them with the same tools as the rest of the Docker ecosystem. The Dockerfile isn't an explicit deployment guide if some of the steps are hidden. Actually, they don’t need to know anything but the location of the X server and an optional display that they target. See Dockerizing .NET Apps with Microsoft's Build Images on Docker Hub. X requires a server component, allowing interaction within the application to draw their content and get input from the user’s input devices.  April 2020 |, Site Reliability Engineering (SRE): The Big Picture The second statement you see uses the RUN command to tell the container, once it is running, to call mkdir c:\myapp.At this point, it creates a new directory inside our container itself called c:\myapp.. At this point Docker has downloaded and built a containerized application based of the Microsoft/iis image with all the base prerequisites needed for setting up an IIS server. It won't change very often. In our previous series, we looked at how to deploy Kubernetes and create a cluster.We also looked at how to deploy an application on the cluster and configure OpenStack instances so you can access it.

Pluralsight If you use a derived image, make sure it has the same release cadence as the base images. Being slimmed down may have problems though - certain Windows APIs just aren't present in Nano Server, so while your app may build into a Docker image it may not run correctly. Docker containers have changed the way we think about build and test environments since they were introduced five years ago. Without a healthcheck, Docker has no way to know the app is failing. You can run any application in Docker as long as it can be installed and executed unattended, and the base operating system supports the app. You can download and run MSIs using the same approach.

You can right click, and access the menu to change some of the settings. HEALTHCHECK is one of the most useful instructions in the Dockerfile and you should include one in every app you Dockerize for production.  August 2018 |, Handling Data and Stateful Applications in Docker The docker run command creates a new container instance, from the image we just created, and runs it.-v ${PWD}:/app mounts the code into the container at “/app”. The command runs when the container starts, so if your check exercises the main path in your app, it acts as a warm-up. Docker runs a container to compile your source code using the tools in the Docker image. The setup is pretty straightforward and requires nothing more than an X server running in your host.
