Alpine support - musl libc

I’m getting the following error while attempting to run the example on alpine.

/var/www/node_modules/bindings/bindings.js:83
        throw e
        ^

It’s prolly a good idea to support musl Alpine environment… It’s really tiny and awesome

Another +1 for alpine support… If your goal is to build secure containers, ubuntu and debian fail to meet the requirement with all the bloat they include.

Install scan tools

See https://github.com/aquasecurity/trivy

RUN apk add curl
&& curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/master/contrib/install.sh | sh -s – -b /usr/local/bin
&& trivy --no-progress --download-db-only

This will fail the docker image build if there are problems

RUN trivy filesystem --exit-code 1 --no-progress /

^^ This is secure, run the same on the other base images, and you will see all sorts of security vulnerabilities.
