The platform team's status page lives in ~/status-page with a Dockerfile already written. Read it, build it as status-page:0.1, and run it.

Read the Dockerfile and list the files it can copy:

You start in your home directory. Building here fails, because . (the context) is ~, and there is no Dockerfile in it:

Build with ~/status-page as the context, either by changing into it or by passing its path:

cd ~/status-page
docker build -t status-page:0.1 .

Count the numbered steps in the output, then run the image. The app listens on 3000 inside the container:

docker run -d --name status -p 8080:3000 status-page:0.1
curl localhost:8080/health
