I'm trying to set up an dev environment for Vue.js and rails API following a tutorial.

Eventually I hit a hurdle when trying to run the following command:

docker-compose run backend rails db:create

Here is the error:

$ docker-compose run backend rails db:create

Starting am-full-stack_db_1_b7f6ee37d2e4 ... done

Error response from daemon: OCI runtime create failed: 

container_linux.go:348: starting container process caused "exec: 

"rails": executable file not found in $PATH": unknown

Here is my file tree

App

autheg-backend

autheg-frontend

docker-compose.yml

Here is my docker-compose.yml

version: '3'

services:

  db:

    image: postgres

    ports:

      - "5432"

  backend:

    build:

      context: autheg-backend

      args:

        UID: ${UID:-1001}

    volumes:

      - ./autheg-backend:/usr/src/app

    ports:

      - "8080:8080"

    depends_on:

      - db

    user: rails

  frontend:

    build:

      context: autheg-frontend

      args:

        UID: ${UID:-1001}

    volumes:

      - ./autheg-frontend:/usr/src/app

    ports:

      - "3000:3000"

    user: frontend

Result of 'docker-compose run backend env'

Thanks!

Where is your backened dockerfile for rails development like this example:-

# Base image:

FROM ruby:2.5



# Install dependencies

RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs



# create application directory

RUN mkdir /myapp



# Set our working directory inside the image

WORKDIR /myapp



# Setting env up

ENV RAILS_ENV='development'

ENV RACK_ENV='development'



COPY Gemfile /myapp/Gemfile

COPY Gemfile.lock /myapp/Gemfile.lock

RUN bundle install

ADD . /myapp



EXPOSE 3000



CMD [ "bundle", "exec", "puma", "-C", "config/puma.rb" ]

This is caused because the path is not set in the Docker container, it's set on your development/local machine. Use the following command:

docker-compose run backend bundle exec rails db:create

to do db migration use:

docker-compose run backend bin/rails db:create

# or

docker-compose run backend bundle exec rails db:create

/backend/Dockerfile

FROM ruby:2.5



ARG UID

RUN adduser rails --uid $UID --disabled-password --gecos ""



ENV APP /usr/src/app

RUN mkdir $APP

WORKDIR $APP



COPY Gemfile* $APP/

RUN bundle install -j3 --path vendor/bundle



COPY . $APP/



# Setting env up

ENV RAILS_ENV='development'

ENV RACK_ENV='development'



CMD [ "bundle", "exec", "rails", "server", "-p", "8080", "-b", "0.0.0.0"]

./docker-compose.yml

version: '3'

services:

  db:

    image: postgres

    ports:

      - "5432"

  backend:

    build:

      context: autheg-backend

      args:

        UID: ${UID:-1001}

    command: bundle exec rails s -p 8080 -b '0.0.0.0'

    volumes:

      - ./autheg-backend:/usr/src/app

    ports:

      - "8080:8080"

    depends_on:

      - db

    user: rails

  frontend:

    build:

      context: autheg-frontend

      args:

        UID: ${UID:-1001}

    volumes:

      - ./autheg-frontend:/usr/src/app

    ports:

      - "3000:3000"

    user: frontend

Then

docker-compose up

Now you should be able to see the rails site using:
localhost:8080 (instead of 3000)

Hope that helps you get started
