docker - apt-key 命令在 shell 上有效，但在 Dockerfile 上失败

Question

以下命令在 shell 中运行时似乎有效

apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF 

但在 a 中执行时失败Dockerfile，如下所示：

Warning: apt-key output should not be parsed (stdout is not a terminal)
Executing: /tmp/apt-key-gpghome.1CIuj3LUOP/gpg.1.sh --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
gpg: cannot open '/dev/tty': No such device or address

特定的DockerfileRUN 命令在图像上执行，而openjdk:8图像又从buildpack-deps:stretch-scm

Answer 1

Solved by adding --no-tty on the apt-key adv command also;

Any idea however why this was happening?
