我无法访问SSH或HTTP-alt。 Ubuntu容器在MacOSX上运行。由于相同的原因,我认为SSH和HTTP-alt都是有问题的。我正在使用dockerfile和docker-compose进行设置。因为我是Docker的新手,所以可能会有多余的命令。我的主机禁用了防火墙。

您可以使用此Dockerfile
FROM ubuntu:16.04
RUN apt-get update && apt-get install -y openssh-server
RUN mkdir /var/run/sshd
RUN echo 'root:THEPASSWORDYOUCREATED' | chpasswd
RUN sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/'
/etc/ssh/sshd_config
# SSH login fix. Otherwise user is kicked off after login
RUN sed 's@session\s*required\s*pam_loginuid.so@session optional
pam_loginuid.so@g' -i /etc/pam.d/sshd
ENV NOTVISIBLE "in users profile"
RUN echo "export VISIBLE=now" >> /etc/profile
EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]
这将在容器的端口22上暴露ssh。那么您可以运行以下命令来了解哪个主机端口已连接到ssh的容器22端口。
docker port <name of container> 22
此示例应用程序为您的问题提供了解决方案。看看它。 https://docs.docker.com/engine/examples/running_ssh_service/

不幸的是,这最终成为设备防火墙问题,我在服务器上使用“ nc -l 22”,在客户端(Linux计算机)上使用“ telnet IP -p 22”进行了故障排除。
