Change into the linux_tweet_app directory.
$ cd ./hybrid-workshop/linux_tweet_app/
Use docker build to build your Linux tweet web app Docker image.
$ docker build -t <user-name>/linux_tweet_app .
Note: Be sure to substitute your Docker Hub username. Ensure you include the dot at the end '.'
The -t tags the image with a name. In our case, the name indicates which DTR server and under which user's repository the image will live.
Note: Feel free to examine the Dockerfile in this directory if you'd like to see how the image is being built.
Your output should be similar to what is shown below

Use docker push to upload your image up to Docker Trusted Registry.
$ docker push <user-name>/linux_tweet_app
The output should be similar to the following:
The push refers to a repository [<user-name>/linux_tweet_app]

In your web browser head back to your Docker Hub account to see the newly pushed image.
Now let's run our application by creating a new service.
In order to create the service, we'll need to define:
docker service create --publish 8088:80 <user-name>/linux_tweet_app
docker container run --detach -p 80:80 daverendon/linux_tweet_app
