Docker Desktop clones the repository into a Docker volume and uses the dev environment details to build the environment locally, then mounts the Docker volume that contains the code into the container. You can find the extension names by their VS Code Marketplace URL item name. You may even determine that the benefits of these paid subscriptions are right for you even if it's not required. There are a few ways to take advantage of this. Because the dev environment needs to include the .NET image, although a very small version of the image, this process may take a few minutes. You need to be at least on Git version 2.29.0. However, I always assume that if something confused me, it must have also confused someone else. People have been using Dockerfiles to create .NET dev environments for a few years already. Docker defines small businesses as those with fewer than 250 employees or less than $10 million annual revenue. VS Code then connects to the container running the environment, starts it up, and opens the project. Although this article will focus on Docker Dev Environments - one of those new features - there are others to be aware of. Extensions that affect the UI are installed but heavy-duty extensions like C# need to be installed into the container directly. For the Docker Dev Environment, you need a few more things, which means using your own Dockerfile that starts with the SDK image and then adds only four lines. This article assumes that you have some familiarity with Docker, and with .NET, Visual Studio Code, and source control. The person you're collaborating with may be working on a completely different project - maybe golang or something with an entirely different set of dependencies. Once I updated to the latest version of Git, Docker Desktop was able to create dev environments from private repos as well. Remember that the environment is isolated in a Docker volume, so they can do this without impacting anything they're working on using their own computer, whether that's on metal or in a separate running (and isolated) dev environment. Use the following steps to ensure that the Service Fabric Yeoman template generator is working on your machine: Node.js and Node Package Manager must be installed on your Mac. Docker already gave us a way to spin up our development environments relatively quickly and for duplicating a teammate's environment, a docker-compose file that referenced the needed images has always been a great way to share. Maintaining a container continuously from your local source code is resource intensive, so by basing the environment on a code stored in a repository such as GitHub, Docker can create the dev environment much more quickly as a one-off when it's time to share. Optional: Build your extended Service Fabric image. That includes pulling the .NET SDK image referenced in Dockerfile. For example, here's the URL for the C# extension: My extensions.json file lists that under recommendations. To stop and clean up the container, use the following command. After making this change, I commit and push the project back to GitHub and then, in Docker Desktop, create a new Dev Environment from the repository. Initially, I didn't understand why a docker-compose feature was considered part of Docker Desktop. Fellow Docker Captain, Ajeet Raina, talks about these differences in this blog post https://collabnix.com/getting-started-with-docker-dev-environments/. There's an easy solution! Some great examples of investing in the Docker platform are new features that arrived in Docker Desktop in 2021. You can watch the log and when it's complete, you'll get another continue button, as seen in Figure 4. I used dotnet new console to create a new project called Hello Code and then opened the folder in Visual Studio Code. Keep in mind that I have slooooow Internet at my house in the countryside so if you have decent speeds, it will be much faster! Now that you see what goes into creating the Dev Environment, it may seem silly to add Dockerfile to every .NET 6 project you may want to share with others. Note that Docker Desktop is also coming to Linux in 2022! Desktop (please complete the following information): Version of Docker Desktop: Visual Studio Code's Remote Container's extension also lets you create development environments. Docker Desktop just does things differently and when you escalate your use into its dev environment sharing features, it does provide a clear advantage. Have a question about this project? Guess which way I prefer? By clicking Sign up for GitHub, you agree to our terms of service and In a new directory, create a file called Dockerfile to build your customized image: You can adapt the image above with a Dockerfile to add additional programs or dependencies into your container. But I'm a .NET developer, so for this preview, I have to feed some info into the project that Docker Desktop will read in order to set up the development environment. The Docker extension for VS Code allows you to right-click on the Dockerfile and choose Build Image. You could be working on one branch and have another in a dev environment. I named mine julielerman/net6devenvironment:latest. My lack of familiarity with Dev Environments in general meant that I had to go through a steep learning curve. Figma File (Source). fun *&>|",{cdOz-,zah%e2#Ld:MlpiX&Wf]Eo9I'6l.Zs2C]a^&Qop0[zL"@z Q^n{a4aIq/6nSa5liOK.^0!w[uhh:r xLA)m?xB We'll take a look at your proposition! Note that if you don't see this prompt, it could be for the same reason that I wasn't getting prompted at first: I'd disabled this feature in the VS Code setting, Extensions: ignore Recommendations. In the Docker Desktop dashboard, there's a new menu shortcut for Dev Environments. Once again, I can verify that .NET 6 is in my environment with dotnet version. When you hover over any of these extensions, a short explanation is displayed saying that the extension needs to run in the Remote Extension Host. Once I updated to the latest version of Git, Docker Desktop was able to create dev environments from private repos. Dev Environments Unable to use without updating Docker. I'll do that from the same computer I'm coding on but I could do it from any computer where Docker Desktop is running. The free usage continues via a Personal License, which applies to most of us, as it's for individuals, education, open-source, and small businesses. Select the Docker icon, and then select Preferences > Daemon > Advanced. To Reproduce btmp8hk48156 }vF|f( PYYcqnw&'GA6H0 (Nr>2On,%{ufL:7O/Hd6G3PD0/rS-q6/y9\'r:WIk|1g*Y^32-"?8p, 9y((O{r^XKi2wWaU lJ@/ozh4lglE BC fakq.lAtGa,'cHo27]14Vg,pi|z^v Visual Studio Code Remote Containers is doing the same thing. Although there are other ways to get Docker onto your development computer, this is certainly the simplest. This document covers how to set up your Mac for development. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. On top of that, by focusing on creating a custom dev environment, I've learned so much in a short time. Additional context If the base .NET image is already on your system, that will be quicker than having to pull the .NET image during the process. Describe the bug With that in mind, I'll keep my source code in a GitHub repository. Docker Desktop also pushes the code for the Hello Code app into the image. I don't mind doing this because it's such a quick task. In the midst of all my app icons. Now that the code and the needed instructions for creating the dev environment are in the repository, anyone with access (mine is public) can create a local dev environment from it. Docker can create Dev Environments from your local source code or from a Git repository. Last updated: March 14, 2022. But I also want to make sure that you understand what Docker Desktop is. It's pointing to the Docker Hub URL where you can read the description of the SDK image. For more information, see our, https://docs.docker.com/cloud/aci-integration/, https://docs.docker.com/cloud/ecs-integration/, https://collabnix.com/getting-started-with-docker-dev-environments/, github.com/dotnet/dotnet-docker/blob/main/src/sdk/6.0/bullseye-slim/amd64/Dockerfile, https://github.com/felipecruz91/docker-dev-env-dotnet-demo/blob/main/.docker/Dockerfile.devenv, https://hub.docker.com/_/microsoft-dotnet-sdk/, mcr.microsoft.com/dotnet/sdk:6.0-bullseye-slim, https://docs.docker.com/desktop/dev-environments/#start-a-dev-environment-from-a-local-folder, http://code.visualstudio.com/api/advanced-topics/remote-extensions#architecture-and-extension-types, marketplace.visualstudio.com/items?itemName=ms-dotnettools.csharp, 716MB image that provides the .NET environment, Small volume (<1MB) that contains the code from the repository, 176MB volume that contains the instance of VS Code server. I initialized the repository and published it to GitHub. To create Service Fabric applications by using Yeoman, follow these steps: After you install the generators, create guest executable or container services by running yo azuresfguest or yo azuresfcontainer, respectively. And you can see in Figure 3 that I've pasted in the URL of my repository. You may have a number of extensions installed in VS Code, but they aren't all installed in this isolated instance of VS Code. For particular revisions, please visit the Docker Hub page. The software can be installed by using HomeBrew, as follows: Current versions of brew cask install java may install a more recent version of the JDK. In fact, there are licensing issues that prevent them from taking care of this for you. The other steps in the Service Fabric for Eclipse documentation are also applicable: build an application, add a service to an application, uninstall an application, and so on. To install or update the Service Fabric plug-in for Eclipse to the latest version, follow these steps. It should take a bit longer than that when it's also creating the dev environment with .NET. So from VS Code I can easily do this from the Source Control tab. ~/Library/Containers/com.docker.docker/Data/database/com.docker.driver.amd64-linux/etc/docker/daemon.json. Create and deploy your first Service Fabric Java application on Linux using Yeoman, Create and deploy your first Service Fabric Java application on Linux using Service Fabric plug-in for Eclipse, Create a Service Fabric cluster in the Azure portal, Create a Service Fabric cluster by using Azure Resource Manager, Understand the Service Fabric application model, Use the Service Fabric CLI to manage your applications, Prepare a Linux development environment on Windows. There's more that gets installed as part of Docker Desktop such as docker scan and even Kubernetes. One reason is that it isn't using the same base image but there may be others. Using Side Menu click on Dev Environments, Click on banners "please update Docker Desktop to continue", Upon failure to trigger an update, proceed to step 5, Restart docker Hoping to retrigger Automatic Update, Observe missing resolution instructions and proceed to several more common locations in search of a solution(See tldr; above), Clicking on "Update docker now" on the Dev Environments Page, Clicking on "Please update Docker Desktop" banner notification, In preferences > General > Under Automatically check for updates - Click "Check for updates now", After launching Docker Desktop display "Update docker now" banner, click "Start Update", Clicking the "bug icon" (i.e Troubleshoot) Click "Check for updates". Now you can quickly start a local copy of Service Fabric whenever you need it by running: Provide a name for your container instance so it can be handled in a more readable manner. Each of those subscriptions offers advanced features and support (docker.com/pricing). Because you've made changes to the project, it's time to commit them and push the updates to the GitHub repository. I tried this magical path and failed, even though it noted my C# code and even when it containerized the app itself. OmniSharp brings you IntelliSense, snippets, CodeLens, debugging support, and many other features that enhance coding in C#. This grants Visual Studio Code the necessary rights to install its server APIs in the container. In fact, the name is a relatively new change as the single moniker for both the Windows and macOS versions of Docker's developer offering. What Docker Desktop created for this environment was: Note that when I created the environment using VS Code's Remote Container, the image it created for the .NET 6-based container was 1.5GB. It's quite possible that by the time this article is published, .NET support will be added. It's .NET with a whole bunch of other things added in. Next, I started the Create Dev Environment a second time. Before you decide to skip to that end result, I'll warn you that it didn't make sense to me until I had gone through the first steps. You can check your version with git version and compare it to the current version shown at git-scm.com/downloads. Already on GitHub? I also want to point out a hiccup I ran into. As I'm writing this in early 2022, you'll notice the PREVIEW icon attached to the menu in Figure 1. This results in quite a bit of chicken pecking, exploration, and subsequent dead ends in commonly recognized locations. Being able to automatically use the dev environments that are already available for Golang, Ruby, Java, and JavaScript is definitely a bonus. This is useful for isolating something that you are working on so that you can have other dev environments running concurrently. In no particular order, the following screenshots are the state and possible locations where I was hoping to find a method to update docker. And it won't mess with the state of your own work. Docker Dev Environments run on your computer, not in the cloud. You can find the version by clicking on the About Docker Desktop menu. The first line is just a comment, so I didn't count it among the four. You don't have to install anything or pull and run images and then shell into them. If you installed a newer version of .NET on your computer, you have to add a global.json file to each project that targets an earlier runtime. After you create and build your Service Fabric application, you can deploy your application by using the Service Fabric CLI: Connect to the Service Fabric cluster that is running inside the container instance on your Mac: From inside your project directory, run the install script: Install the .NET Core 3.1 SDK for Mac to start creating C# Service Fabric applications. For example, one might have a particular version of .NET installed along with all of the dotnet tools you need for your project. You can read more about Docker Desktop licensing in their FAQ: docker.com/pricing/faq. However, as it's for special purposes, the file needs to be tucked into a special subfolder named .docker that must be present at the root of the repository. But you want to look at something a team member or even a friend in the .NET community, is working on in .NET 6. I harassed the very kind Docker engineers to no end and spent a lot of time experimenting and testing things out. And it's a container that you can use yourself or share with others. However, we will be using this container in the next step. Docker Desktop was always free to use. Note that you may have to scroll down to see the Get Started button shown in Figure 2. Suddenly the promise of a ready-to-go development environment seems false. In the past, this was just referred to as Docker Community Edition. A'\,0-M5avT|uf;4R;42|'Q0/0HpL\*RAu$ QQ@URC{ ,y/}6'@NX }js;A&!779#4gg\=psZwk|X4uoy}y@u/U;6$kqI>s] 5;.4>Rz(Q6; 9[s'9#_3/8kBQK`^Y>BFz8j4'GZ7`LW0GEldf. There are so many interesting benefits. For users in those larger orgs, one of the commercial subscriptions (Pro, Team, or Business) is required. I'm almost a little embarrassed to share that confusion now. Creating it from a local folder can impact performance inside the container (read more about that at https://docs.docker.com/desktop/dev-environments/#start-a-dev-environment-from-a-local-folder). It defaults to creating a new dev environment from an existing Git repo. I'll never forget the first time I used a container for SQL Server instead of having to install SQL Server on my computer! On the Dev Environments page, click Create a New Environment and, on the next page, Get Started. But with a little knowledge and a little advanced planning, we .NET developers can benefit from the feature just as easily. But when you create a dev environment from local source or a source code repository, Docker Desktop builds the environment locally and does so in Docker volumes, which avoids any tax on file system performance. Q&XX.Xj*)_=UgkQNRT/F"JCCo?2t=b_3K You may want to do more than run and debug the code that came in this environment and once again, as a .NET developer, well, in this case C#, you will hit another small and surmountable snag. Yet another level is available to Team and Business subscribers where you can take a snapshot of the dev environment and easily share it as a Docker image with other members of your team. For example, Compose V2 can talk directly to Azure and AWS so that you don't have to switch between CLIs for a series of related tasks. The plug-in requires this type of instantiation to work with the Docker container on your Mac. Therefore, I think it's worth exposing myself at the risk of having some readers think Well duh, Julie! You can read more about this feature (referred to as contexts) in the ACI integration docs (https://docs.docker.com/cloud/aci-integration/) and the ECS integration docs (https://docs.docker.com/cloud/ecs-integration/). I'll create mine from the repository into which I've pushed my project and its environment-savvy Dockerfile. This wasn't just to understand how to use the feature, but also why. To build a Service Fabric Java application on your Mac, JDK version 1.8 and Gradle must be installed on the host machine. They start with a runtime image and then add in things like Curl and PowerShell. Note that you may get prompted to install the Remote Containers extension in VS Code. The way to trigger this feature is to add an extensions.json file into the .vscode folder. And because this gets installed in the container, not in the VS Code volume, you have to re-install it in every new Dev Environment you create. Docker Development Environments can be created manually by writing a Dockerfile or much more easily through a wizard in the Docker Dashboard. In the end, it's all about collaboration. Azure Service Fabric doesn't run natively on macOS X. If I were coding in golang, Java, JavaScript, or Ruby, I could head to Docker Desktop to create the dev environment because it has the ability to detect those for project types and reference its own pre-defined dev environments. And there's a lot of value in creating your own customized dev environments anyway. You can build Azure Service Fabric applications to run on Linux clusters by using macOS X. Published in: CODE Magazine: 2022 - March/April For example, For example, if your application is listening on port 8080, add the following -p tag: docker run -itd -p 19000:19000 -p 19080:19080 -p 8080:8080 --name sfonebox mcr.microsoft.com/service-fabric/onebox:u18, The cluster will take a moment to start. With that in place, your .docker/config.json file can point to the image instead of to your Dockerfile. I also wanted to relay some timings, but please keep in mind that this is just on my little MacBook and I have slow Internet! You signed in with another tab or window. You can even make and push that change from this container if you want. Running container-based apps requires running SF on a Linux host. When it is running, you can view logs using the following command or jump to the dashboard to view the clusters health: http://localhost:19080. privacy statement. To create a self-contained environment for my project, I needed a sample project. I already mentioned the ability to have different default .NET runtimes available. There's a feature that allows you to list recommended extensions for a project and VS Code prompts you to install them when you open the folder in VS Code. This installed a native Docker engine (Windows or macOS), the docker-compose CLI, and a simple UI for managing images and containers, called Kitematic. To connect to the cluster before deploying applications run the command below. Docker uses this image as a basis for the final contained environment that it builds for you. When I open the new Dev container in VS Code, I'm prompted to install the recommended extensions (Figure 7). You can directly modify the daemon configuration settings in Docker. Then I closed VS Code and deleted the environment in Docker Desktop but I left the Dev Environment image in place and the two volumes. Notice that at this point, I haven't done anything to containerize this application. Docker Desktop originated as a developer-focused version of the Docker Engine that you can use on your development computers. If your application is listening on certain ports, the ports must be specified by using additional -p tags. For example, consider if you have to install any dotnet CLI tools, such as dotnet-ef. Starting with a clean Docker system (no images, no volumes), it took about 1.5 minutes for Docker Desktop to create the assets. In 2019, Docker encapsulated the engine, docker-compose, and their own UI, referred to as a dashboard, into Docker Desktop. moment with Docker dev environments was opening one up on a computer that doesn't have .NET 6 installed and being able to use the .NET CLI to make changes to source code for a .NET 6 API and run it from the dev container. When you open the environment in VS Code, you will be working with a volume that has its own instance of the VS Code server in it. It's a must for C# developers. After writing all of the above I noticed that the Docker Menu Icon had an exclamation mark and a quick command (CMD+R) to trigger an update. As a .NET developer, my aha! In mid-2021 Docker switched to a mix of licensing scenarios. Consider how this could reduce merge conflict issues when you need to switch tasks quickly. Those won't be in a generic .NET dev environment anyway. In scenarios when you need the same environment repeatedly, just as with any Docker image, you will certainly benefit from that initial pull. tldr; Docker Desktop throws notifications without offering resolution. Imagine you're working on .NET 5 code so .NET 5 is the highest version installed on your computer. Docker Dev Environments allows you to define the tooling, dependencies, and runtime stack to develop your app inside a container. Sign in Well occasionally send you account related emails. After running out of places to look in the desktop app, writing this ticketI observed the monochromatic Docker Menu Icon displaying an exclamation mark. Steps to reproduce the behavior: Expected behavior I hadn't updated Git in a while on the laptop I'm using for this and Docker Desktop couldn't access my repos unless they were public. Additionally, there's a lot more information in the log window when that dev environment Dockerfile is being acted on. You can specify a particular branch if you prefer by adding @branchname to the end of the URL. Before you get started, you'll need: The system requirements for installing Docker Desktop on Mac. By Julie Lerman And finally, I run my very wonderful app to reveal the Hello, Code! Docker Desktop makes this a fully integrated workflow, giving you a simple click-of-the-button way to share your dev environment, pushing it to your Docker hub so that other team members can grab that environment and code from their own Docker Desktop dashboards. But the Docker Desktop-integrated Dev Environments takes this collaboration to the next level by removing the disruptive nature of switching gears, development environments, and your source control workflow when you want to take a look at something that your teammate is working on. You can create the Dev Environment explicitly, build its image, and then push the image to a Docker repository. Service Fabric provides scaffolding tools that help you to create a Service Fabric application from the terminal by using the Yeoman template generator. Getting some revenue from Docker Desktop will enable Docker, the company, to continue to invest in further development. Currently, the Dev Environment builder won't see that folder if it's not named using all lower case, so be sure to do that up front. As I was learning and hadn't done some things correctly, resulting in .NET not getting added into the dev environment, I reached this stage rapidly - in less than 10 seconds. The .NET SDK always targets the latest installed version. Why would you create one from a local folder? However, VS Code provides a solution. Once my dev environment base image existed on my computer, subsequent iterations of creating a new dev environment for this or other .NET 6 projects took less than 10 seconds. Otherwise, the container will think it's finished with its tasks and shut down immediately.
