带有--build-arg且带有多个参数的docker build [英] docker build with --build-arg with multiple arguments

问题描述

根据文档，可以为标志--build-arg定义多个arg，但是我不知道如何.我尝试了以下方法:

According to the documentation, it's possible to define multiple args for the flag --build-arg, but I can't find out how. I tried the following:

docker build -t essearch/ess-elasticsearch:1.7.6 --build-arg number_of_shards=5 number_of_replicas=2 --no-cache .

=>这将返回错误.

我也尝试过:

docker build -t essearch/ess-elasticsearch:1.7.6 --build-arg number_of_shards=5,number_of_replicas=2 --no-cache .

=>这会将一个变量number_of_shards设置为值"5，number_of_replicas = 2"

=> This sets one variable, number_of_shards, to the value "5,number_of_replicas=2"

有什么想法可以定义多个参数吗?

Any idea how I can define multiple arguments?

推荐答案

对每个参数使用--build-arg.

如果要传递两个参数，则在每个参数后添加--build-arg，例如:

If you are passing two argument then add --build-arg with each argument like:

docker build \
-t essearch/ess-elasticsearch:1.7.6 \
--build-arg number_of_shards=5 \
--build-arg number_of_replicas=2 \
--no-cache .
