Docker nginx container exists instantly

Question

I want to have some control over the official nginx image, so I wrote my own Dockerfile that adds some extra funtionality to it.

The file has the following contents:

FROM nginx
RUN mkdir /var/www/html
COPY nginx/config/global.conf /etc/nginx/conf.d/
COPY nginx/config/nginx.conf /etc/nginx/nginx.conf

When I build this image and create a container of the image using this command:
docker run -it -d -v ~/Projects/test-website:/var/www/html --name test-nginx my-nginx

It will exit instantly. I can't access the log files as well. What could be the issue? I've copied the Dockerfile of the official nginx image and this does the same thing.

Answer 1

So I didn't know about the docker ps -a; docker logs <last container id> command. I executed this and it seemed I had a duplicated daemon off; command.

Thanks for the help guys ;)!
