我已经在寻找类似的问题,并尝试更改配置中的几项内容,但找不到解决方案。
我正在尝试通过 SSH 连接到 Docker 容器,这是 Dockerfile:
FROM ubuntu
RUN apt-get update && \
apt-get install -y openssh-server
RUN useradd remote_user && \
echo "remote_user:test1234" | chpasswd && \
mkdir /home/remote_user/.ssh -p && \
chmod 700 /home/remote_user/.ssh && \
mkdir -p -m0755 /var/run/sshd
COPY id_rsa.pub /home/remote_user/.ssh/authorized_keys
RUN chown remote_user:remote_user -R /home/remote_user && \
chmod 600 /home/remote_user/.ssh/authorized_keys
RUN apt-get install -y php php-mbstring php-xml php-bcmath php-fpm && \
apt-get install -y composer && apt-get install -y vim
RUN apt-get install -y nginx
CMD /usr/sbin/sshd -D
一旦我尝试使用 ssh -Tv remote_user@staging.local
以“remote_user”身份连接到容器(其中“staging.local”是容器 IP),我收到此消息:

remote_user@staging.local's password:
如您所见,它无法连接并要求输入密码。
如果我在我的主机上有 ls -ll
.ssh 文件夹文件,我有这个:
-rw------- 1 xxx xxx 2610 Jan 3 12:08 id_rsa
-rw-r--r-- 1 xxx xxx 577 Jan 3 12:08 id_rsa.pub
-rw-r--r-- 1 xxx xxx 222 Jan 3 12:25 known_hosts
如果我 docker exec
以 root 用户身份进入容器并看到 /home/remote_user/.ssh
的权限,我有:
home 文件夹权限:
drwxr-xr-x 1 root root 4096 Jan 3 11:22 home
remote_user 文件夹权限:
drwxr-xr-x 1 remote_user remote_user 4096 Jan 3 11:22 remote_user
.ssh 文件夹权限:
drwx------ 1 remote_user remote_user 4096 Jan 3 11:22 .ssh
authorized_keys 文件权限:
-rw------- 1 remote_user remote_user 577 Jan 3 11:08 authorized_keys
答案 0 :(得分:0)
尝试将 /home/remote_user/.ssh/authorized_keys
的权限更改为 400 而不是 600。除此之外,我没有看到我自己的设置有任何区别。
附言 我的设置在 ubuntu 18.04 上运行,所以也许他们从那时起改变了一些东西。

如果您转发端口,它应该可以工作:
docker run -p 222:22 your-image
然后:
ssh -p 222 remote_user@localhost
