Hi, I’m a newbie in docker and discourse and today I encountered a problem. I follow these two posts to install docker and discourse: https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-18-04, How To Install Discourse on Ubuntu 16.04 | DigitalOcean.
After I set up my discourse, I did some modification on it, committed it to a docker image and pushed the image to dockerhub. Then I tried to pull the image from dockerhub and run it to get my discourse, but after I typed docker run my_image in terminal, it seemed this did not work. I googled online but did not find a good answer. Anyone has the idea on how to run this image? Thank you.
