使用 Docker 构建 Angular 失败：nginx.conf - 没有这样的文件

Question

I'm trying to containerize my Angular app using Docker.

I'm pretty new to Docker, hence I followed a tutorial, adding a Dockerfile with the following content:

FROM node:13.3.0 AS compile-image

WORKDIR /usr/src/app
COPY package.json package-lock.json ./

RUN npm install

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

COPY . ./
RUN ng build --prod

FROM nginx
COPY nginx.conf /etc/nginx/nginx.conf
COPY --from=compile-image /opt/ng/dist/myproject /usr/share/nginx/html

But somehow it fails at Step 9/10 returning following error:

COPY failed: stat /var/lib/docker/tmp/docker-builder934487773/nginx.conf: no such file or directory

Answer 1

Modified the Dockerfile, you can start from this and update as required.

FROM node:13.3.0 AS compile-image    
COPY package.json package-lock.json ./    
RUN npm install && mkdir /angular-app
ENV PATH="./node_modules/.bin:$PATH"
WORKDIR /angular-app
COPY . .
RUN ng build --prod
FROM nginx
RUN rm -rf /usr/share/nginx/html/*
COPY --from=compile-image /angular-app/dist /usr/share/nginx/html

You can refer to nginx.conf documentation from http://nginx.org/en/docs/beginners_guide.html & if it is needed create the conf file and add a COPY statement in dockerfile

Answer 2

Having the docker-compose and the dockerfile in the same folder might work.
