推荐答案

运行 docker exec -i 而不是 docker exec -it 解决了我的问题.事实上，我的脚本是由 CRONTAB 启动的，它不是终端.

Running docker exec -i instead of docker exec -it fixed my issue. Indeed, my script was launched by CRONTAB which isn't a terminal.

提醒一下:

Usage: docker exec [OPTIONS] CONTAINER COMMAND [ARG...]

Run a command in a running container

  -i, --interactive=false    Keep STDIN open even if not attached  
  -t, --tty=false            Allocate a pseudo-TTY
