I have a folder : /docker on my project root and it contains certain files like Apache configs which I need to copy to the correct folders during teh build.

Project-root
------docker folder
-----------apache.conf

Now

DOCKERFILE

In my dockerfile i have a copy command which copies the whole of root to the container.

`Issue`

I don't want the docker folder to be copied to the built image.

I added docker to the .dockerignore. But this leads to the problem that these files are not sent to the build context and then the build command fails.

WORKAROUND

Use the RUN command in the dockerfile to remove the docker folder instead of using .dockerignore

QUESTION

Is there any better solution?

DOCKER FILe:
FROM <baseimage>
WORKDIR /var/www/html/
COPY . /var/www/html/MYFOLDER
COPY ./docker/apache.conf /etc/httpd/conf/apache.conf
COPY ./docker/sites-enabled /etc/httpd/sites-enabled

Sending files to the build-context doesn't mean that these will be included in the image that you are going to generate. use `COPY` command in Dockerfile to decided which all things matter in the final image. – fly2matrix Nov 26 '18 at 10:55
@fly2matrix : you mean there is a exclude flag in the COPY command? Can you send me a link for the same? – Bhumi Singhal Nov 26 '18 at 11:02
Can you share your Dockerfile ? – fly2matrix Nov 26 '18 at 11:06
@fly2matrix: done – Bhumi Singhal Nov 26 '18 at 11:14
Take a look at this solution: https://stackoverflow.com/questions/43747776/copy-with-docker-but-with-exclusion – fly2matrix Nov 26 '18 at 11:38
@fly2matrix : using a ! before the file name means that the same would be copied using the COPY command. – Bhumi Singhal Nov 26 '18 at 11:40
