docker ubuntu networking bash

I'm attempting to set up I've been researching this but Quick question that's been bugging me - I'm working on a project and hit a roadblock. I'm trying to set up a Docker container on Ubuntu 22.04 that should be able to forward traffic from a specific port to the host machine. I used the following command to run my Docker container: ```bash docker run -d --name my_container -p 8080:80 my_image ``` However, when I try to access the application from my browser using `http://localhost:8080`, I'm getting a `Connection refused` behavior. I verified that the application within the container is running properly. When I enter the container, I can access the application using `curl http://localhost:80` and it responds as expected. I've checked the logs of the container using `docker logs my_container`, and I see no errors. I also tried running the container with `--network host`, but that didn't help either. The configuration in my `Dockerfile` looks like this: ```dockerfile FROM nginx:alpine COPY ./my_app /usr/share/nginx/html ``` Additionally, I confirmed that my UFW (Uncomplicated Firewall) is configured to allow traffic on port 8080 with the command: ```bash sudo ufw allow 8080/tcp ``` Despite all this, the scenario continues. Any suggestions on what might be going wrong or how to debug further? I'm wondering if there might be an scenario with the Docker daemon or the network configuration on my Ubuntu installation. For context: I'm using Bash on Ubuntu. Thanks in advance! Has anyone dealt with something similar?
