Dockstore uses git-secrets to help make sure that keys and private data stay out of the source tree. To install and check for git secrets:

npm ci
npm run install-git-secrets

This should install git secrets into your local repository and perform a scan. If secrets are found, the run will error and output the potential secret to stdout. If you believe the scan is a false-positive, add the line glob to .gitallowed.
