Can't connect to docker via ssh using testcontainer

My task is connected to the container via ssh from tests.

I have dockefile: (almost from https://docs.docker.com/engine/examples/running_ssh_service/)

FROM ubuntu:18.04
RUN apt-get update
RUN apt-get install -y openssh-server
RUN mkdir /var/run/sshd

RUN echo 'root:root' |chpasswd

RUN sed -i 's/^#?PermitRootLogins+.*/PermitRootLogin yes/' /etc/ssh/sshd_config
RUN sed -i 's/UsePAM yes/#UsePAM yes/g' /etc/ssh/sshd_config
RUN sed 's@sessions*requireds*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd

RUN mkdir /root/.ssh 
RUN apt-get clean && 
 rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

ENV NOTVISIBLE "in users profile"
RUN echo "export VISIBLE=now" >> /etc/profile
EXPOSE 22

CMD ["/usr/sbin/sshd", "-D"]

Then I use this dockerfile by testcontainer:

public static GenericContainer localServer(@NotNull Integer port, @NotNull String user, @NotNull String password, Path dockerfile) {
 return new GenericContainer(
 new ImageFromDockerfile()
 .withFileFromPath("Dockerfile", dockerfile))
 .withExposedPorts(port)
 .withFileSystemBind(FileUtil.getTempDirectory(), "/home/", BindMode.READ_WRITE);

When I run my test, the container successfully runs, but I can't connect via ssh. 49154 - is value from sftp.getMappedPort(22)

ssh root@localhost -p 49154 

Got:
ssh: connect to host localhost port 32836: Connection refused

What's a detail I've missed? Thanks!

.withExposedPorts(port) - it seems that you're trying to externalize the port, while you image defines a static port "22".

Use .withExposedPorts(22) instead.

  then make sure that your image actually listens on all interfaces, not just "localhost". Have you tried to run it with just docker run -p 22 my-image?

  Yes, I also can run docker with the terminal only: dockerfile docker build -t image_name . docker run -d -P --name container_name image_name docker port test_sshd 22 ssh root@localhost -p 32768 and it works

  In your docker run example, you didn't map the /home/ folder, but I see this in the example code you provided. Could you please double check that it is not caused by it?
