[英]Is there a way to specify only changed parameters using aws cloudformation update stack and avoid explicit UsePreviousValue for unchanged parameters?
[英]Azure DevOps Cloudformation update stack fails using parameters file (##[error]ValidationError: Parameters: do not exist in the template)
我有一個使用 AWS CloudFormation 更新堆棧任務的 Azure DevOps 構建管道。 CF 模板是指存儲在參數文件中的參數。 部署時,構建失敗,因為任務找不到我在參數文件中引用的參數。
例如文件本身:
[
{
"ParameterKey": "EnvironmentParameter",
"ParameterValue": "dev"
},
{
"ParameterKey": "DBHost",
"ParameterValue": "xxxxxxxxx.amazonaws.com"
}
]
該任務引用了我的模板參數文件:
這是模板本身的參考:
"dbhostparameter" : {
"Type" : "AWS::SSM::Parameter",
"Properties" : {
"Name" : "/LCS/Database/host",
"Type" : "String",
"Value" : {
"Fn::Sub" : [
"${env}",
{
"env" : {
"Ref" : "DBHost"
}
}
]
},
這里是失敗 output (這表明它成功加載了模板參數文件)

缺少實際 CF 模板的參數部分。 沒有這個,參數文件就沒有參考點,因此部署失敗。
根據評論。
問題是缺少Parameters section
部分。
解決方案是添加部分。
