我正在尝试设置一个 Ubuntu 容器,openssh-server
这样我就可以从主机 ssh 进入它。我知道这不是标准的做法,但我真的很想拥有ssh
.
这是我的Dockerfile
# Select base image
FROM ubuntu:16.04
# Set the current working directory
WORKDIR /home
# Update the system, download any packages essential for the project
RUN dpkg --add-architecture i386
RUN apt-get update && apt-get upgrade -y
RUN apt-get install -y git build-essential make gcc vim net-tools iputils-ping ca-certificates openssh-server libc6:i386 libstdc++6:i386
# Allow ssh root login
RUN echo "root:root" | chpasswd
# RUN rpl "PermitRootLogin prohibit-password" "PermitRootLogin yes" /etc/ssh/sshd_config
RUN sed -i 's/prohibit-password/yes/' /etc/ssh/sshd_config
RUN cat /etc/ssh/sshd_config
RUN mkdir /root/.ssh
RUN chown -R root:root /root/.ssh;chmod -R 700 /root/.ssh
RUN echo “StrictHostKeyChecking=no” >> /etc/ssh/ssh_config
RUN service ssh restart
# Open port 22 so linked containers can see it
EXPOSE 22
# Import any additional files into the environment (from the host)
ADD otherfile .
我启动容器,docker run -t -d -p 2222:22
但每当我尝试 ssh 进入它时,我总是会收到错误ssh_exchange_identification: Connection closed by remote host
:
➜ ssh -v -p 2222 root@localhost /bin/bash

有谁知道导致此错误的原因以及如何解决?
