[Vue.js] docker multistage build fails on vue.js

This is my dockerFile located at vDocker/Dockerfile

# build stage
FROM node:lts-alpine as build-stage
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build

# production stage
FROM nginx:stable-alpine as production-stage
RUN apk add –no-cache bash
COPY ./vDocker/nginx.conf /etc/nginx/conf.d/default.conf
COPY –from=build-stage /app/dist /usr/share/nginx/html

EXPOSE 80 443

CMD [“nginx”, “-g”, “daemon off;”]

I also have docker-compose located at root directory.

version: ‘3’

context: .
dockerfile: ./vDocker/Dockerfile
container_name: web_client
restart: unless-stopped
tty: true
- /var/www/app/ssl/certbot/conf:/etc/letsencrypt
- /var/www/app/ssl/certbot/www:/var/www/certbot
- 80:80
- 443:443

After running docker-compose build, It gives me the following error: Service ‘web_client’ failed to build: COPY failed: stat /var/lib/docker/overlay2/67b326c995a1ce52fb3ee2a792d84ffe9bc403aa5962755a2b89f1ab925a1242/merged/app/dist: no such file or directory

Any idea why?

Solution :

You don’t need to name the second stage.

How the build looks like depends on how you set it up and I don’t know it. But what you can do is:

run the first stage as a separate Dockerfile
after the last RUN add RUN ls -lart -> this should print the contents of the directory and you can check if the /app/dist really exists

For the rest the code looks good.
