You will need a github account to login into CircleCI and add a project. After adding the pproject, you need to add two variables into your CircleCI project settings. These two variables are: DOCKER_USER and DOCKER_PASS. These are the user name and password you use to push images to your dockerhub account.
docker login
docker pull sxie2004/web_test
docker run -p 8000:8000/tcp sxie2004/web_test
You should see the sample site running on port 8000. You should see "Hello world!"
