Update Docker Image of Confluence

[yvonnearnoldus]

Hi,

I've tried to execute the guide: Update the Confluence Docker image to use Oracle JDK but something is wrong.

When I run `docker run atlassian/confluence-server:6.8.2` the image starts fine.

But when I follow the guide, I get the following error: [FATAL tini (6)] exec /entrypoint.sh failed: No such file or directory.

I also tried it without changing anything to the files in the repository but got the same result.

I found my problem. The guide does not work when you are running on Windows.

Some issues with line conversions from git to windows to docker.

I solved the problem by adding the following line to the Docker file.

`RUN dos2unix /entrypoint.sh`

and installing dos2unix with the apk add command.
