ubuntu - docker 错误 : ln: target 'ps' is not a directory

Question

我有一个带有以下命令的 dockerfile:

RUN mkdir build run logs frontend/dist \
    && apt-get -y install curl \
    ...
    && ln -s /usr/bin/esmtp /usr/sbin/sendmaildocker ps

运行后 $ docker build -f Dockerfile -t tag-name .我得到错误:

ebconf: unable to initialize frontend: Dialog
debconf: (TERM is not set, so the dialog frontend is not usable.)
debconf: falling back to frontend: Readline
debconf: unable to initialize frontend: Readline
debconf: (This frontend requires a controlling tty.)
debconf: falling back to frontend: Teletype

Answer 1

必须删除最后的 ps 是一个错字:

&& ln -s /usr/bin/esmtp /usr/sbin/sendmaildocker
