Building Docker image:

$ VER=v1.0.6-snapshot; docker build -t mojaloop/simulator:$VER .; docker push mojaloop/simulator:$VER

Run in Docker (in Dev)

$ docker-compose up

or (to rebuild the docker image if source code has been modified)

$ docker-compose up --build

Auditing Dependencies

We use npm-audit-resolver along with npm audit to check dependencies for vulnerabilities, and keep track of resolved dependencies with an audit-resolv.json file.

To start a new resolution process, run:

npm run audit:resolve

You can then check to see if the CI will pass based on the current dependencies with:

npm run audit:check

And commit the changed audit-resolv.json to ensure that CircleCI will build correctly.
