Hi, I would like to know if it is possible to consume environment variables during build time inside the dockerfile.
The image is being created in a micro service running in kubernetes. It needs to consume the micro service environment variable (not secret) to compile an Angular project and then to copy the corresponding dist folder to nginx html directory.
The variable I would like to consume is $COUNTRY
Here is the dockerfile:
FROM node:10-alpine as builder RUN echo $COUNTRY WORKDIR /app COPY . /app RUN cd /app && npm install RUN cd /app && npm run build-$COUNTRY FROM nginx:alpine RUN rm -rf /usr/share/nginx/html/* COPY nginx.conf /etc/nginx/nginx.conf COPY --from=builder /app/dist/$COUNTRY/. /usr/share/nginx/html CMD ["nginx", "-g", "daemon off;"]
Thanks in advance.
