@pitaj just follow you guide, if without sudo, I may not have permission to exec this command , you had suggest?

I try to this docker chain, and got some error after exec sudo ./bin/com-nodebb npm install:

Successfully built ee060087bd12
Successfully tagged nodebbdockerdev_nodebb:latest
npm WARN saveError ENOENT: no such file or directory, open '/opt/nodebb/package.json'
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN enoent ENOENT: no such file or directory, open '/opt/nodebb/package.json'
npm WARN nodebb No description
npm WARN nodebb No repository field.
npm WARN nodebb No README data
npm WARN nodebb No license field.

and idea?
