Running Nginx on Docker
I’m learning how to build Docker images from Dockerfiles. Here’s my current Dockerfile:
I can build this image, run it, and connect to the container with
docker run -t -i -p 80:80 mytestimage /bin/bash/. Then, I can run
nginx and connect to the “hello world” page from a web browser.
But I can’t get Nginx to run as a daemon (without manually starting it from the container’s shell). I’ve tried
docker run -d -p 80:80 mytestimage, but
docker ps is empty. What am I doing wrong? I’ve been looking at the official Nginx Dockerfile, but I’m not sure which parts I need to add to my own Dockerfile.

you need to add following in Dockerfile
CMD [“nginx”, “-g”, “daemon off;”]
and the docker container can be run using command : docker run -d -p 8980:80 test-nginx
above port 8980 just an example, this is configured from Dockerfile
The problem is that nginx doesn’t run in the foreground so every time your container executes the
CMD directive, it returns and then the container exits.
You need to add the following to your
/etc/nginx/nginx.conf at the top
Then you can just run your container like this:
docker run -ti -p 80:80 mytestimage
