/bin/sh: 1: composer: not found

Asked by: Kit

I am trying to build a Dockerfile.

FROM php:7

RUN mkdir -p /home/winpc/test/laravelApp/app
WORKDIR /home/winpc/test/laravelApp/app


COPY composer.json /home/winpc/test/laravelApp/app
RUN composer install

COPY . /home/winpc/test/laravelApp/app

CMD php artisan serve --host=0.0.0.0 --port=8181
EXPOSE 8181

But when i run the build command it says:

docker build -t lar-app .
/bin/sh: 1: composer: not found
The command '/bin/sh -c composer install' returned a non-zero code: 127

But when I type just composer it is properly displaying the information I guess the problem is with the command:

RUN composer install

Here I am using Ubuntu 14.04
