Unable to use wetty Docker container to connect to an ssh Docker container

Describe the bug I’m unable to use the wetty web shell to connect to another Docker container that I’ve spun up to serve as an SSH server. I’ve confirmed that I can connect to the Docker container via SSH using my host, but I’m unable to access it via the wetty Docker container/web shell.

To Reproduce Steps to reproduce the behavior:

1. I have the following Dockerfile:

FROM ubuntu:latest
RUN apt update && apt install  openssh-server sudo -y
RUN useradd -rm -d /home/ubuntu -s /bin/bash -g root -G sudo -u 1000 test
RUN  echo 'test:test' | chpasswd
RUN service ssh start
EXPOSE 22
CMD ["/usr/sbin/sshd","-D"]

1. Build the ssh Docker container with docker build -f Dockerfile -t ssh-test . and run using docker run -it -p 22:22 ssh-test

2. Verify that you can connect to the container via ssh (by trying to connect via ssh from the host to the container):

1. Now spin up the wetty container docker run --rm -p 3000:3000 wettyoss/wetty --ssh-host=127.0.0.1 --ssh-port=22

2. Now access the wetty terminal at localhost:3000, and insert the test username and test password.

3. I get an incorrect login via wetty but I’ve confirmed that I’m able to ssh into the ssh-test Docker container from my host.

Expected behavior I would expect that I can access the ssh-test container via SSH using the wetty web shell.

Yes it can be confusing, as localhost is not always “localhost” 😂 (you’re definitely not the first one getting confused!)

Glad this helped 👍
