有人可以解释(并可能给出解决方法)以下docker-compose的行为吗？

给出以下文件:

Dockerfile

FROM alpine:3.8

COPY ./entrypoint.sh /entrypoint.sh

ENTRYPOINT [ "/entrypoint.sh" ]

entrypoint.sh

#!/bin/sh

until [ ! -z "$PLOP" ]; do
    echo -n 'enter value here: '
    read PLOP
done

echo "Good ... PLOP is $PLOP"

exit 1

泊坞窗,compose.yml

version: '3.7'

services:
  plop:
    tty: true
    stdin_open: true
    image: webofmars/plop:latest

输出将如下:

1) ./entrypoint.sh

docker-stdin> ./entrypoint.sh
enter value here:
CASE1
Good ... PLOP is CASE1

这似乎OK

2) docker-stdin> docker run -it webofmars/plop

enter value here: CASE2
Good ... PLOP is CASE2 …
