1. Challenge

   Create a Dockerfile for the Application

   1. Create a Dockerfile.
   2. Fork the source code repository on GitHub: https://github.com/linuxacademy/cicd-pipeline-train-schedule-docker
   3. If you want to clone the repo elsewhere and create the Dockerfile yourself, just be sure to commit and push it to your fork.
   4. If you would like to create the file in GitHub itself, then use the Add file then Create new file button when viewing the GitHub repo.

   • Here is a sample Dockerfile:

     FROM node:carbon
     WORKDIR /usr/src/app
     COPY package*.json ./
     RUN npm install
     COPY . .
     EXPOSE 8080
     CMD [ "npm", "start" ]
     

   5. Once you have a docker file, log in to the learning activity environment and clone your fork inside the cloud_user home directory.
2. Challenge

   Build a Docker Image Using the Dockerfile and Run It

   1. Get into your source code directory.
   2. Build a docker image using your Dockerfile.
   3. Run the app in a container using the image. Be sure to use port 8080.
   4. Once the container is running, you should be able to access the train schediule app in a browser: http://<your learning activity environment public IP>:8080
