Angular Book

Testing in a Container

It is now an excellent time to test our image in a container. Use the following command to create a temporary container out of our image, and run the application at port 3000:

docker container run -p 3000:80 --rm ng-docker

Once you stop the process with Ctrl+C, the Docker is going to perform a cleanup.

Running the container should not take much time. If you now visit the http://localhost:3000/ in your browser, you should see the Angular CLI application up and running.

Note that the log output gets redirected to your console. You should see the nginx output if you switch to the console right now:

You can now stop the process and let Docker cleanup the data, or continue experimenting with the application.
