Can't connect to ActiveMQ Console running in Docker container

Question

I made a Dockerfile to run an ActiveMQ service from, and when I try to connect to the console on the host machine using http://127.0.0.1:8161/ in my web browser, it says 127.0.0.1 didn't send any data. in Google Chrome. This is with running the docker image using docker run -p 61613:61613 -p 8161:8161 -it service_test bash .

However, when I run it using docker run --net host -it service_test bash , Google Chrome says 127.0.0.1 refused to connect. , which leads me to believe I'm doing something by adding the --net flag but I'm not sure why it can't connect. Maybe a port forwarding issue?

My Dockerfile is as follows

FROM <...>/library/ubuntu:20.04

ADD <proxy certs>

    DEBIAN_FRONTEND=noninteractive apt-get install -y --no-install-recommends software-properties-common && \

For context, I am running activemq from the container using activemq console , and trying to connect to it from my host OS using Google Chrome.

Got it to work!

For those having the same issue, I resolved it by changing the IP address in jetty.xml from 127.0.0.1 to 0.0.0.0 . I am now able to connect to my containerized AMQ instance from my host OS.
