Ever run into an issue with environments when running other peoples code? Don’t have the proper modules in your environment? Don’t want to modify your existing environment just to run a CLI program?
Dockerize it! Make the application runnable on any machine using docker. Using a default alpine program date as an example
Step 1: Create a Dockerfile wrapping your application
# Base image
FROM alpine
# Copy your runnable program with the COPY
# docker command.
# The first argument of the ENTRYPOINT will be command executed when
# the docker container is run
ENTRYPOINT ["date"] Step 2: Build the dockerfile
docker build .Step: 3 Run the program with docker run
docker run [container-name] -hFull example
