Simple App Containerization hands-on lab with Docker

Running CAT Sample App locally

Now you are ready to run the CAT sample app on your local machine. This sample app is a ASP.NET app which you will also use on Azure with the Orchestrator in the second portion of the lab. This code material are available here.

Clone the repo from github into a new local directory on your machine using:

mkdir ASPNETAPP
cd ASPNETAPP  
git clone https://github.com/dave-read/container-service-dotnet-continuous-integration-multi-container 
cd container-service-dotnet-continuous-integration-multi-container

Now, compile the ASP .NET Core application code. This uses a container to isolate build dependencies that is also used by VSTS for continuous integration:

docker-compose -f docker-compose.ci.build.yml run ci-build

On Windows, you currently need to pass the -d flag to docker-compose run and poll the container to determine when it has completed

Note: if you get an error about not being able to access a shared folder, open the Docker for Windows settings from the system tray, and in the Shared Drives tab, ensure that the drive where your lab files are stored is checked (enabled).

docker-compose -f docker-compose.ci.build.yml run –d ci-build

Now build Docker images and run the services:

docker-compose up --build

The frontend service (service-a) will be available at http://localhost:8080.
