"Not a tty" 基于 Alpine 的口是心非图像中的错误

Question

这是我在 Whosebug 上的第一个问题，所以我希望它会遵守社区准则：

我构建了一个 docker image based on an already existing 映像，其唯一目的是运行在容器中进行口是心非，以将文件和文件夹备份到欧洲的 Amazon S3 存储桶中。

口是心非在运行手动放入由图像生成的容器中时工作了几天。现在，我通过带有 CoreOS 的主机上的单元文件转移到运行容器，但事情不再起作用了 - 但该命令也不起作用，我运行它在一个口是心非的容器中手动运行。

运行命令：

 docker run --rm  --env-file=<my backup env file>.env --name=<container image> -v <cache container>:/home/duplicity/.cache/duplicity -v <docker volume with gpg keys>:/home/duplicity/.gnupg --volumes-from <docker container of interest> gymnae/duplicity

env 文件包含以下内容：

PASSPHRASE=<my super secret passphrase>
AWS_ACCESS_KEY_ID=<my aws access key id>
AWS_SECRET_ACCESS_KEY=<my aws access key>
SOURCE_PATH=<where does the data come from>
REMOTE_URL=s3://s3.eu-central-1.amazonaws.com/<my bucket>
PARAMS_CLEAN="--remove-older-than 3M --force --extra-clean"
ENCRYPT_KEY=<derived from the gpg key>

而在 docker run 上调用的 init.sh 看起来像这样：

#!/bin/sh
duplicity \
         --verbosity 8 \
         --s3-use-ia \
         --s3-use-new-style  \
         --s3-use-server-side-encryption \
         --s3-european-buckets \
         --allow-source-mismatch \
         --ssl-no-check-certificate \
         --s3-unencrypted-connection \
         --volsize 150 \
         --gpg-options "--no-tty" \
         --encrypt-key $ENCRYPT_KEY \
         --sign-key $ENCRYPT_KEY \
        $SOURCE_PATH \
        $REMOTE_URL

我试过 -i、-it、-t 和 -d - 但结果总是一样的：

===== Begin GnuPG log =====
gpg: using "<supersecret>" as default secret key for signing
gpg: signing failed: Not a tty
gpg: [stdin]: sign+encrypt failed: Not a tty
===== End GnuPG log =====

gpg 尝试签名时的这个 Not a tty 错误很奇怪。

以前好像没什么问题，或者我在加夜班的时候疯狂打字说曾经能用，现在就是不想用了。

对于遇到同样问题的任何人，感谢 duply 的开发者，我找到了答案 https://sourceforge.net/p/ftplicity/bugs/76/#74c5

简而言之，你需要从gpg 2.1开始添加GPG_OPTS='--pinentry-mode loopback'并添加allow-loopback-pinentry到.gnupg/gpg-agent.conf

这让我离工作设置更近了一步。
