npm install is taking (30+) minute - docker

Question

npm install is taking (30+) minutes in server which runs on debian 9.8.
I want to know what might cause this?
I've already tried npm set progress=false and npm config set registry http://registry.npmjs.org/ but none of it helped.
I'm running it in docker container.
this is my package.json
