angular-cli ng command not found even if it is installed while docker building an image

Question

I have tried to build an image for an app with angular-cli as its controller. In build time with ng build --prod command, the docker builder crash.

I have tried to implement angular-cli on global or local folder, but everytime ng command is called, build console says that it cant build on a folder that is not an angular-cli app.

The problem is that docker build process run ng build on the right folder. Here is my docker file.

Error message: The command '/bin/sh -c ng build --prod' returned a non-zero code: 127 Other error message: /bin/sh: 1: ng: not found

The current directory is set to WORKDIR in each Dockerfile layer so it discards whatever you cd. So change

RUN cd /opt/ && ls -l
RUN ng build --prod

To:

WORKDIR /opt/
RUN ng build --prod

Or:

RUN cd /opt/ && ng build --prod

Also, make sure that the npm directory is in your "PATH" variable.

I am very new to Docker and started playing around with it last night and I came across the very same problem.

I did not use ng build ( i could not get it working at the time) I added the following run command in my dockerfile:

RUN npm run-script build

This was recommended by the terminal and it did work and allow me to continue my steps to build. I don't think that this is best practice? Feedback would be greatly appreciated.
