webapp (Frontend)

webapp.rb: Web app written in Ruby using Sinatra. Includes a Dockerfile for containerized use
Use the Dockerfile to build a container and run it on your laptop or host
Look at the Dockerfile to see how the app is build and configured

Install Docker on your laptop (Docker for Windows or Mac)
Test that Docker is running properly, e.g., docker run docker/whalesay, or docker run --rm -it egray/cmatrix
Clone code from github to your laptop
Update Dockerfile with correct address of ElasticSearch
Build a container for your webapp
Run the container and take and show photos

Use git to clone the repo and then configure the webapp
Show local container images:
docker images
Build a container (don't miss the dot '.' at the end):
docker build -t <image_name> .
Run a container:
docker run --rm -it -p <host_port>:<container_port> <image_name>
Show all running and non-running containers:
docker ps
docker ps -a
Stop a running container:
docker stop <id>
Exec a command (like a shell) into a running container:
docker exec -it <container-name-or-id> bash
To detach yourself from the container, use the escape sequence CTRL+P followed by CTRL+Q.
