Steps to BUILD a Docker Image

gistfile-docker-image.txt

## Build a docker image

- Make sure you are in the folder that contains the `Dockerfile`
- If your folder is `/my-docker-image-name/`, these 3 files should be in your folder:
  ...
  /my-docker-image
  |
  |---Dockerfile
  |---Readme.md
  |---requirements.txt
  ...
- Run: `cd /my-docker-image-name`
- To build the image, run: `docker build -t <image-name>:<version-number> .`
- The above command ensure you have `a dot[.]` at the end of the command included. It means that all the files would be collected and sent to the `docker daemon` context.
- Done, the docker image would take time to build, once done, it is ready on your local system.
- You can push the Docker image to Docker Hub for public access or reuse as a docker image.
