Latest npm release inconsistent with latest docker image

[oeed]

🐛 Bug description

The latest npm release uses Amazon Linux 1, as #84 hasn't been published as an npm release. The latest docker images use Amazon Linux 2. As such, the build and run environments are different causing confusing errors such as /lib64/libc.so.6: version GLIBC_2.18'`.

🤔 Expected Behavior

Build and runtime environments should match.
