Error: Cannot find module '/var/apps/frontend/bash'

Question

I am trying to setup node 15.3.2 version using docker compose file. I have added all the necessary requirements in dockerfile. But after executing docker compose up command, I am facing below error. I tried docker compose --build command as well. If any one have any solution please let me know.

Dockerfile

FROM node:15-alpine3.10
WORKDIR /var/apps/frontend
COPY frontend /var/apps/frontend/
RUN apk update 
RUN apk add alpine-sdk 
RUN apk add --update npm
RUN apk add --update python3 make g++ && rm -rf /var/cache/apk/*
RUN npm install -g npm@9.9.2
RUN rm -rf node_modules
RUN npm cache clean --force
RUN npm rebuild node-sass --force
RUN npm i react@15.3.2 --legacy-peer-deps
RUN npm install --legacy-peer-deps
CMD [ "npm", "start" ]

docker-compose.yml

frontend:
    build:
      context: .
      dockerfile: ./docker/frontend/Dockerfile
    container_name: ui
    command: bash -c "npm config set package-lock false && npm install && yarn run docker"
    networks: ['ao_platform_network']
    depends_on: ['django']
    ports:
      - "8081:8081"
    environment:
      - RAILS_ENV=development
      - RAKE_ENV=development
      - NODE_ENV=development
    volumes:
      - type: bind
        source: ./frontend
        target: /var/apps/frontend

By default, bash is not included with Alpine Linux. So, you need to add this command in Dockerfile:

RUN apk update && apk add bash

But note that just adding this should be more than enough:

RUN apk add bash

You may also add --no-cache option to avoid keeping the downloaded packages in cache:

RUN apk add --no-cache bash
