Controlling your builds with Dockerfiles!

Dockerfiles are used to define how to build Docker containers. Zeet uses Docker under-the-hood to run your applications. You can use a Dockerfile for deeper control over your build process.

If you're not already familiar with Dockerfiles, check out the Dockerfile reference.

Custom Build Args​

All environment variables are automatically passed in to your build as Docker build args.

Example:​

FROM node:latest

ARG ZEET_VERSION
ARG ZEET_PROJECT_NAME

RUN echo "version $ZEET_VERSION of $ZEET_PROJECT_NAME is building!"

CMD sleep 1000

When built in Zeet:

Note the line: version 4c119a4d3b9e1fe57b64d22738a72a336b3adc06 of theonlyjohnny-build-args-test is building!
