How to fix Docker connection reset by peer, Docker Status is UP but cannot connect to sever?

Question

Having this issue of connection reset by peer when doing a curl to to docker server. curl 127.0.0.1:8080

Also cannot access the server from browser, but docker status says: UP 4 hours ago How can one fix this?

tried the following commands and docker seems to work fine but becomes unaccessible after few minutes.

docker build -t abelakponine/dockerimage .
docker run -p 0:8080 -itd --name imagename abelakponine/dockerimage
docker ps -a
docker logs --follow dockerprocessId

Here's what my dockerfile looks like:

FROM python:3.11.6
COPY . /App
WORKDIR /App

ENV PYTHONUNBUFFERED=1

EXPOSE 8080

CMD apt -y update \
        && python3 --version \
        && hostname -I \
        && curl -4 icanhazip.com \
        && pip install -r requirements.txt \
        && pip install waitress gunicorn django-livereload-server whitenoise \
        && python3 manage.py runserver 0.0.0.0:8080

Answer 1

So to solve this issue is simple, after many trials I figured what the problem is.

First of all, the port mapping 0:8080 was set to a port that was not listening on the server, so I corrected this to 8080:8080

Secondly I added --network host to the run command, this tell the docker server to run on the host server

Note: Since we are adding --network host there's no need for including -p 8080:8080 as this becomes redundant.

the complete code looks like this:

docker run --network host --name testimage -itd abelakponine/testimage

also do

docker logs --follow cointainerId

to view running docker logs

doing:

netstat -lnt

shows the running port: 127.0.0.1:8080
