Set up the local development environment

This is the part with some potential for stumbling-blocks, because it involves the installation of software. However the tools are very reliable and the vast majority of users encounter no problems. If you already have Docker and Node.js installed on your system, skip to the last step and install subzero-cli

If you do run into any difficulties, please don’t hesitate to contact subZero support, who will be glad to help you out.

Every component of the subZero runs as a docker container which makes it possible to work on a project locally in the same environment as it runs on in the cloud. Using Docker means that not only does every member of the team work in the same environment, but they’re all in the same environment that the application will have in production.

Install Docker and Docker Compose

Launch Docker. You can check that it’s running correctly with:

docker run --rm busybox true

Install Node.js

Use the pre-built installer for your platform. Check that it's correctly installed with:

node -v

Install subzero-cli

Use npm (or yarn) to install the subzero developer tools


If you are on windows, run this first

npm install --global --production windows-build-tools

Install subzero-cli as a global package

npm install -g subzero-cli

Check that it was installed correctly
