For some reason, I find containers are confusing and my goal with my Azure Tips and Tricks (opens new window) is to try to make things easier. In this mini-series, I'll walk you through Docker (opens new window) and how I use it with Azure. Below is a list of post that you can expect for this week.

# Create an app to run inside a Container Image with Docker
Let's continue where we left off (opens new window) in our last post, which showed how to get started using Docker. We're specifically looking at how I use Docker with Azure in these posts.
Begin by opening two tabs instances of either command prompt or terminal. In the right tab, enter the following command to see what docker images are available.
Michaels-MacBook-Pro:~ mbcrump$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE microsoft/aspnetcore-build latest c0c285a7a306 39 hours ago 1.85GB
Let's run the following command passing the
run parameter, an
interactive terminal and
naming our app and the
image id which the first couple of letters (found with the above command) is good enough.
After this command executes, I'll be inside my container.
docker run -it --name myapp c0
I can validate this by running
root@40bac5113803:/# dotnet --info .NET Command Line Tools (2.0.2) Product Information: Version: 2.0.2 Commit SHA-1 hash: a04b4bf512 ...
I know this because I don't have dotnet core tools installed on my Mac. Very cool! You now have a running container that has the dotnet core tools with just a couple of commands.
We could further validate this by running
uname -r or just
root@40bac5113803:/# uname -r 4.9.49-moby root@40bac5113803:/# uname Linux
Let's go ahead and create an app. Run through the following commands to create a new
dotnet core console app.
dotnet new console
