AWS Elastic Beanstalk Docker Does not support Multi-Stage Build


I am struggling to get my build deploying to AWS on Docker. I have no idea where the solution lays as this is my first time with Docker. I have got it all working fine locally, but when I deploy I get the following error in Elastic Beanstalk:

2020/04/30 05:35:02.330900 [ERROR] An error occurred during execution of command [app-deploy] - [Docker Specific Build Application]. Stop running the command. Error: failed to pull docker image: Command /bin/sh -c docker pull node:13.3.0 AS compile-image failed with error exit status 1. Stderr:"docker pull" requires exactly 1 argument.
See 'docker pull --help'.

This is what my Docker file looks like:

FROM node:13-alpine as builder

WORKDIR /opt/ng
COPY package.json package-lock.json ./
RUN npm install

ENV PATH="./node_modules/.bin:$PATH"

COPY . ./
RUN ng build --prod

FROM nginx:1.18-alpine
COPY nginx.conf /etc/nginx/conf.d/default.conf
COPY --from=builder /opt/ng/dist/angular-universal-app/browser /usr/share/nginx/html

Can someone please point me in the right direction? Or is this method of Multi-Stage builds not supported by Elastic Beanstalk's Docker version?


Solution

  • I had the same problem. Actually I check the following rows in my log file:

    2020/05/26 17:26:30.327310 [INFO] Running command /bin/sh -c docker pull node:alpine as builder
    2020/05/26 17:26:30.369280 [ERROR] "docker pull" requires exactly 1 argument.
    

    As you can seen, it tries to make a 'docker pull' with 3 arguments:

    1. node:alpine
    2. as
    3. builder

    and of course, that is not possible because it requires only 1 argument. Thus, apparently AWS Elastic Beanstalk doesn't support stage naming. For this reason I solved using an Unnamed builder:

    FROM node:13-alpine
    

    and in the end:

    COPY --from=0 /opt/ng/dist/angular-universal-app/browser /usr/share/nginx/html
    

    Final Dockerfile:

    FROM node:13-alpine
    
    WORKDIR /opt/ng
    COPY package.json package-lock.json ./
    RUN npm install
    
    ENV PATH="./node_modules/.bin:$PATH"
    
    COPY . ./
    RUN ng build --prod
    
    FROM nginx:1.18-alpine
    COPY nginx.conf /etc/nginx/conf.d/default.conf
    COPY --from=0 /opt/ng/dist/angular-universal-app/browser /usr/share/nginx/html
    

    For me it works using that solution. If someone has any problem, please share the last-100-lines log
