#Deploying containers with Dockerfile Docker files are the second way of deploying containers. Instead of manually configuring the server and commiting the changes, we can do it all from a script.

1. Open Visual Studio Code and create a new Dockerfile. (Open VS Code and save the file as a Dockerfile, no extension)
2. Add the following lines to the file

FROM nginx
RUN apt-get update && apt-get install -y wget
WORKDIR /usr/share/nginx/html/
RUN rm index.html
RUN wget https://raw.githubusercontent.com/JesperJakobsen/Dockerdemo/master/index.html

3. Copy the text
4. Create a new folder the host with mkdir <folder>, then change your working directory to that folder cd foldername
5. Create the dockerfile on the host with touch Dockerfile, then nano Dockerfile, paste our commands and exit nano with Ctrl + x, press Y to save the file.
6. Run the command docker build -t <image-name> ., this wil create the new image based on the public image nginx and deploy a simple webpage to the folder.
7. Run your new docker container with docker run -d -p 80:80 <image-name>
8. Now your website should be running, so get the IP from Azure and check that everything is fine.
