为什么密码修改失败？chpasswd：权限被拒绝

  • 772

我的 Dockerfile

FROM ubuntu:latest
RUN apt update
RUN apt install -y openssh-server sudo 
RUN useradd -ms /bin/bash -g root -G sudo -u 1000 remote_user
USER remote_user
WORKDIR /home/remote_user
RUN mkdir /home/remote_user/.ssh && chmod 700 /home/remote_user/.ssh
COPY remotecentos.pub /home/remote_user/.ssh/authorized_keys
RUN stat /etc/passwd
RUN  echo 'remote_user:*****2599*****' | chpasswd -c SHA256
RUN service ssh start
EXPOSE 22
CMD ["/usr/sbin/sshd","-D"]

我有错误

如何修复容器内的权限？

我应该如何更改密码行？

ubuntu permissions

    remote_user您的 Dockerfile在调用之前将当前用户更改为chpasswd. 要使用chpasswd，您需要是 root。您可能希望将该RUN行（以及任何其他需要超级用户权限的命令）移到该行之前USER。我也期待ssh服务的启动会因为类似的原因而失败。
