It’s kind of magical because you don’t have to create and manage a virtual machine to run the container on if it’s a simple application. Although first you need to define specs for the instance. Azure will create a container and run it as an Azure Container Instance. Right click on the image and choose Run instance. Which is fine if you aren’t trying to orchestrate a number of images and that matches my case. Running the Container from the ImageĪ cool feature of this registry is that you can right click and run an image. There’s more to the story but it is beyond the scope of my goals here. Naturally I tweeted my confusion:Ī discussion ensued with input from Rich Lander and Steve Lasker at Microsoft where first they confirmed that this was expected behavior. I was surprised to see this, wondering why Azure didn’t just grab them from docker hub and why I was uploading those big files directly. If its your first time pushing this image to the repository, the tooling will also push the ASP.NET Core SDK and runtime images that are listed in the app’s Dockerfile. Keep in mind that you’ll want VS2017 to be set to run a RELEASE build, not a DEBUG build. I can have other versions under different tags.īack in Visual Studio, after walking through the publishing tool’s questions for creating a new repository, the final step is to go ahead an publish which will build the image and push it up to the target repository. The dataapi has only one image which the publishing tool automatically tagged “latest” for me. I have three repositories in mine where I’ve been experimenting. You may have different versions of a particular image so each “set” is a different repository. I’ve circled the link to see repositories which is where your images are accessible. Here’s the overview page of a registry I let the publishing tool create for me.

I’m not here to advise on how to manage azure finances, just how to do the task. Well, there may be technical or financial constraints, but the point is that you can have multiple images in a registry. And you can store any number of images in a single registry. You can have multiple container registries in your azure account. My goal for this blog post is to get the image into the Azure Container Registry so that’s my choice. I have a VIsual Studio Subscription and can publish it to an Azure Container Registry if I want or to Docker Hub or to some other registry. And part of that profile is to choose where to publish the image. Then you will want to create a publish profile. Right click the project and choose Publish. But we’re using Docker, so you’re not publishing the app, but the docker image that can run the app for you. Once you’ve got the app working it’s time to publish it. Publishing the Image to Azure’s ACI Registry So its all self-contained, nice and neat.

That environment variable gets passed into the running container and my app has code to read it and include that password in teh connection string. Because I’m only debugging, I create a temporary environment variable on my system with the value of the password and when I debug or run the app from VS2017, the password variable will be found. Becasue there’s no value there, Docker will look in the host’s environment variables. In the environment mapping, I have a sequence item where I’m defining the DB_PW key but I’m not including a value. I go into detail in part 2 of the article (the one in the May 2019 issue) but the bottom line is that I use a docker environment variable in my docker-compose.yml file. And because I used the docker tools to add container orchestration, I have another folder in the solution for docker-compose. My ASP.NET Core API project is DataAPIDocker. That means I have a connection string to deal with but I want to keep the password a secret. So whether I’m debugging locally with IIS or Kestrel, debugging locally inside of a Docker container or running the app from a server or the cloud, I can always access that database. My API uses EF Core and targets an Azure SQL database. I will relay those steps in this blog post. Well, the deployment was pretty easy but there were some new steps to earn in order to deal with storing a password for making a connection to my Azure SQL database. Part 2: EF Core in a Docker Containerized App, May 2019īut I didn’t have room to include the important task of deploying the app I’d written, although I worked hard to do it.

The article series will be in the April, May and June issues of MSDN Magazine. All of this was done in VS 2017 and I took advantage of the VS2017 Tools for Docker. I’ve just finished writing a three part series on building a containerized ASP.NET Core API that uses EF Core for its data persistence. (Written in advance, but published on May 2 when the relevant article is finally available.)
