[Angular CLI] Build application without remove dist folder for Docker Volume

When we develop the Angular app inside Docker container, we can simulate Production envioment by build Angualr App instead of using 'ng serve':

ng build --watch --delete-output-path false

'--delete-output-path false': tells it do not delete the dist folder when doing the build.

nginx.dockerfile file:

FROM nginx:alpine
LABEL author="Dan Wahlin"
COPY ./config/nginx.conf /etc/nginx/conf.d/default.conf

# Use the following commands to build the image and run the container (run from the root folder)
# 1. You'll first need to build the project using `ng build --watch --delete-output-path false`

# 2. Now build the Docker image:
# docker build -t nginx-angular -f nginx.dockerfile .

#3. Run the Docker container:
# To run the container we'll create a volume to point to our local source code. On Mac
# you can use $(pwd) to reference your local folder where your running Docker commands from.
# If you're on Windows there are several options to point to the folder. See my following post:

# docker run -p 8080:80 -v $(pwd)/dist:/usr/share/nginx/html nginx-angular
