1) Mise En Place

• DockerHub Account https://hub.docker.com/signup
• Docker installed
  • Mac https://hub.docker.com/editions/community/docker-ce-desktop-mac
  • Windows https://hub.docker.com/editions/community/docker-ce-desktop-windows
• GitHub Account https://github.com/join?source=header-home

2) Set Up Equipment

• Fork repo https://github.com/bryan-nice/creating-recipes-for-other-chefs.git
• Create DockerHub Repo and Link forked GitHub Repo to it

3) Get Ingredients

Clone repo forked repo

git clone https://github.com/bryan-nice/creating-recipes-for-other-chefs.git 

4) Create Shopping List

• Open the file nedocsRandomForestForecast.R
• At the top of the file add #!/usr/bin/env Rscript. This will enable the bash interpreter to use the correct kernel so it can be executed like an app.
• Look for the line where the variable packages exists and take note of the packages required for this model to function.
• Let's inspect the R file to understand how data is following in and out of the model process.

5) Create Recipe Directions

• Open Dockerfile and add the list of required pacakages to the line with ENV R_PACKAGE. (Should look like ENV R_PACKAGE "'a','b','c'")
• Let's inspect the Dockerfile to understand the instructions.
• Save and close Dockerfile

6) Make Dish

Execute docker build command to create the image locally.

docker build --tag nedocs .

7) Taste Test

Test the container with the example data set to verify everything works correctly.

docker run --rm -it -v ${PWD}/examples:/examples nedocs \
    --r-script /r-files/nedocsRandomForestForecast.R \
    --input-data-file /examples/nedocs_dataset.csv \
    --output-data-file /examples/nedocs_output.csv

8) Serve to Other Chefs

Commit and push completed recipe to GitHub repo.

git add
git commit -m “finish my first recipe for a chef”
git push

After check the GitHub repo to verify the Dockerfile exists. Finally, check DockerHub to make sure the build process was triggered.
