Get the container

If you do not want to build the container by your own, you may use the following to get the image from DockerHub: docker pull tweetsentimentanalysis/analyzer:latest

Run the container

After you have built the container, you may run it using the following command: docker run -e AWS_ACCESS_KEY_ID='...' -e AWS_SECRET_ACCESS_KEY='...' -e NO_THREADS='1' tweetsentimentanalysis/analyzer:0.0.1 which runs the container, i.e. consumes fetched tweets, analyzes them and pushes them back to a message queue.
