amazon-web-services - 来自 github 的模板路径无效，但直接在 cli Cloudformation 中执行时无效

Question

我尝试从 github 执行 aws cloudformation 部署，但它表明模板格式错误。从 CLi 控制台或直接在 AWS Cloudformation 中执行相同的操作时，如果生成堆栈，可能会出现什么问题？

aws cloudformation 部署 --template-file plantilla_test.yaml --stack-name plantillalambdagithub --capability CAPABILITY_IAM

Answer 1

在您的模板中，您定义了一些参数，但没有给出默认值。因此，您可以使用尝试执行的命令为它们提供值，也可以在 JSON 文件中定义它们。

使用命令执行

aws cloudformation deploy \
    --template-file plantilla_test.yaml \
    --stack-name plantillalambdagithub \
    --parameter-overrides Runtime=nodejs18.x LambdaName=rainmaker Ambiente=produccion \
    --capabilities CAPABILITY_IAM

您可以使用aws cloudformation deploy help来查找部署命令的每个参数的详细信息。

使用命令和 JSON 文件执行

创建参数的 JSON 文件

cat <<EOL > parameters.json
{
    "Parameters":
    {
        "Runtime": "nodejs18.x",
        "LambdaName": "rainmaker",
        "Ambiente": "produccion"
    }
}
EOL

执行部署命令

aws cloudformation deploy \
    --template-file plantilla_test.yaml \
    --stack-name plantillalambdagithub \
    --parameter-overrides file://parameters.json \
    --capabilities CAPABILITY_IAM

2个文件，即JSON文件和CFN模板都在同一目录下。
