我正在尝试创建一个32位的docker镜像，上面有Googles gRPC。
我创建了从：
扩展的Dockerfilebash: /usr/local/bin/protoc: No such file or directory我能够编译gRPC和Proto Buffers，但是，当我尝试使用protoc时，我得到file。
当我运行file /usr/local/bin/protoc
/usr/local/bin/protoc: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.18, BuildID[sha1]=e87bf6eb1c507bb7f65f3c7687df6a3b41b563be, stripped
时，我看到程序集被视为64位。
uname -m因此，我的问题是如何编写和构建一个实际为32位的docker镜像。当我在容器中运行arch或x86_64时，我得到dpkg --print-architecture，但i386显示SELECT
transaction_transaction.id,
sec_to_time(avg(time_to_sec(extract(HOUR_SECOND from transaction_transaction.transaction_datetime))))
AS average_time_of_day
FROM transaction_transaction
INNER JOIN store_store ON (transaction_transaction.store_id=store_store.id)
INNER JOIN payment_method_card ON (transaction_transaction.card_id=payment_method_card.id)
WHERE (
transaction_transaction.transaction_datetime BETWEEN '2017-08-31 00:00:00' AND '2017-08-31 23:59:59'
AND store_store.company_id=2
AND payment_method_card.profile_id=8
);
，所以看起来它实际上并不是+== id ==+== average_time_of_day ==+
