Getting an error on dockerising nest.js application - docker

Question

I am working on a Nest.js application and this is the Dockerfile that we have. When I run this I am getting an error on the npm run build step in docker.
This is the build task in package.json.
"build": "nest build"
sh: nest: not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
npm ERR! atom-qbuilder-api#0.0.1 build: `nest build`
npm ERR! spawn ENOENT
npm ERR!
npm ERR! Failed at the atom-qbuilder-api#0.0.1 build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

#nestjs/cli (where the nest command comes from) is by default in devDependencies. Unless you've modified your deps in package.json, running npm i --production will not install #nestjs/cli which will lead to the error you currently have. You can either use a multi-staged dockerfile or move #nestjs/cli to your dependencies instead of devDeps.
