docker文件中的Tee命令

我正在尝试使用下面的dockerfile安装RejectionDB

RUN /bin/bash -c "source /etc/lsb-release" && echo "deb http://download.rethinkdb.com/apt $DISTRIB_CODENAME main" | tee "/etc/apt/sources.list.d/rethinkdb.list"
        RUN wget -qO- https://download.rethinkdb.com/apt/pubkey.gpg | sudo apt-key add -
        RUN sudo apt-get update
        RUN sudo apt-get install rethinkdb

安装失败。下面是输出

输出：

Step 22/23 : RUN sudo apt-get update
 ---> Running in 54d07239b6f3
E: Malformed entry 1 in list file /etc/apt/sources.list.d/rethinkdb.list (Component)
E: The list of sources could not be read.
The command '/bin/sh -c sudo apt-get update' returned a non-zero code: 100

似乎源列表写得不正确。 任何帮助都将不胜感激。

提前感谢。

您的源命令不会将变量从/etc/lsb release传输到echo命令。你需要这样的东西：

RUN /bin/bash -c 'source /etc/lsb-release && echo "deb http://download.rethinkdb.com/apt $DISTRIB_CODENAME main"' | tee "/etc/apt/sources.list.d/rethinkdb.list"

谢谢，很好用。
