参数值在 aws cli Cloudformation 中不起作用

Question

我正在通过 AWS CLI 运行我的云形成模板。 它工作正常并在 AWS 门户上创建堆栈，但我面临一个问题，即无法更改默认参数值。 我正在使用 CLI 传递我自己的参数，但只有最后一个参数值从堆栈中更改（即 30） rest 没有更改，而是从模板正文中选择默认值。 我已经通过更改参数的位置尝试了所有可能的事情，但它仍然是一样的。 所以请让我知道我将如何解决这个烦人的问题。 这是我的命令：-

aws --region eu-north-1 cloudformation  create-stack --stack-name cli4  --template-body file://app_cli.json --parameters "ParameterKey"="Maxvalue","ParameterValue"="7","ParameterKey"="increment","ParameterValue"="1","ParameterKey"="incrementtime","ParameterValue"="30"

        },

Answer 1

我能够重现此 CloudFormation 行为，删除参数对之间的逗号（ 如此处所示）为我修复了它：

--parameters ParameterKey=Maxvalue,ParameterValue=7 ParameterKey=increment,ParameterValue=1 ParameterKey=incrementtime,ParameterValue=30

Answer 2

你不需要所有的双引号。 尝试

aws --region eu-north-1 cloudformation  create-stack --stack-name cli4  --template-body file://app_cli.json --parameters ParameterKey=Maxvalue,ParameterValue=7,ParameterKey=increment,ParameterValue=1,ParameterKey=incrementtime,ParameterValue=30
