Building Container Images Using Dockerfiles

1. Create a Dockerfile that uses httpd:2.4 as the base image, then runs basic package updates.
2. Build the 0.1 version of the widgetfactory image using the Dockerfile.
3. Inspect the image to see its size and layers.

1. Remove the Apache welcome page from the image.
2. Build version 0.2 of the widgetfactory image.
3. Inspect both versions of the widgetfactory image to see the differences in size and layers.
4. Add the website data to the container.
5. Build version 0.3 of the widgetfactory image.
6. Inspect versions 0.2 and 0.3 to see the differences in size and layers.

1. Run a container from the widgetfactory:0.3 image in the terminal, to see which command it executes. Remember to publish the web server port.
2. Stop the container running in the terminal, then start it in detached mode.
3. View the website files in the container.
4. Retrieve the main website page from the container and compare it to the copy on the server.
