使用 CDK 部署时 AWS Lambda 不工作

Question

我正在尝试使用 AWS CDK 部署 lambda，但它似乎 working/deployed 不正确。管道中的 "box" 是绿色的，所以没有返回错误。

一切似乎都很好，但是当我运行它手动测试时，我收到下一条消息：

{
  "errorType": "LambdaException",
  "errorMessage": "Could not find the required 'QuickSight.Lambdas.SpiceRefresh.deps.json'.  This file should be present at the root of the deployment package."
}

问题是，如果我手动将 artefact 下载到我的机器上，然后使用 Function package 上传按钮上传，它工作正常。

我有一个 Stack，其中包含 CfnParametersCode，这是我用来创建 lambda 的堆栈。

public class LambdaStack : Stack
{

    public CfnParametersCode LambdaCode { get; set; }

    //code

    private Function BuildSpiceRefreshLambda()
    {
        LambdaCode = Code.FromCfnParameters();

        var func = new Function(this, Constants.Lambda.LambdaName, new FunctionProps
        {
            Code = LambdaCode,
            Handler = Constants.Lambda.LambdaHandler,
            FunctionName = Constants.Lambda.LambdaName,
            MemorySize = 1024,
            Tracing = Tracing.ACTIVE,
            Timeout = Duration.Seconds(480),
            Runtime = Runtime.DOTNET_CORE_2_1,
            Environment = new Dictionary<string, string>()
            {
                {"ENVIRONMENT", Fn.Ref(Constants.EnvironmentVariables.Environment)},
                {"APPLICATION_NAME", Constants.Lambda.ApplicationName},
                {"AWS_ACCOUNT_ID", Fn.Ref("AWS::AccountId")},
                {"LOG_GROUP_NAME", Constants.Lambda.LogGroupName}
            },
            ReservedConcurrentExecutions = 1,
            Role = SpiceRefreshLambdaRole,
            Vpc = this.GetProjectVpc(),
            SecurityGroups = new ISecurityGroup[]
            {
                securityGroup
            }
        });
        return func;
    }
}

然后我有了管道，其中一个步骤是构建 lambda：

var lambdaBuild = new PipelineProject(this, "appLambda", new PipelineProjectProps
{
    BuildSpec = BuildSpec.FromObject(new Dictionary<string, object>
    {
        ["version"] = "0.2",
        ["phases"] = new Dictionary<string, object>
        {
            ["install"] = new Dictionary<string, object>
            {
                ["commands"] = new string[]
                {
                    "echo \"Installing lambda tools for dotnet\"",
                    "dotnet tool install -g Amazon.Lambda.Tools",
                }
            },
            ["build"] = new Dictionary<string, object>
            {
                ["commands"] = new string[]
                {
                    "echo \"Packaging app lambda\"",
                    "(cd app/src/Lambdas/app.Lambdas.Action; dotnet lambda package)"
                }
            }
        },
        ["artifacts"] = new Dictionary<string, object> 
        {
            ["files"] = new[]
            {
                "app/src/Lambdas/app.Lambdas.Action/bin/Release/netcoreapp2.1/app.Lambdas.Action.zip",
            }
        }
    }),
    Environment = new BuildEnvironment
    {
        BuildImage = LinuxBuildImage.STANDARD_2_0
    }
});

var lambdaBuildOutput = new Artifact_("LambdaBuildOutput");


new Amazon.CDK.AWS.CodePipeline.Pipeline(this, "appPipeline", new PipelineProps
{
    ArtifactBucket = Bucket.FromBucketAttributes(this, "artifact-bucket", new BucketAttributes
    {
        BucketArn = "bucket",
        EncryptionKey = "key"
    }),
    Role = "role",
    Stages = new[]
    {
        new StageProps
        {
            StageName = "Source",
            Actions = new[]
            {
                new CodeCommitSourceAction(new CodeCommitSourceActionProps
                {
                    ActionName = "Source",
                    Repository = code,
                    Output = sourceOutput,
                })
            }
        },
        new StageProps
        {
            StageName = "Build",
            Actions = new[]
            {
                new CodeBuildAction(new CodeBuildActionProps
                {
                    ActionName = "Lambda_Build",
                    Project = lambdaBuild,
                    Input = sourceOutput,
                    Outputs = new[] {lambdaBuildOutput},
                }),
            }
        },
        new StageProps
        {
            StageName = "Deploy",
            Actions = new[]
            {
                new CloudFormationCreateUpdateStackAction(new CloudFormationCreateUpdateStackActionProps
                {
                    ActionName = "DeployLambdaapp",
                    TemplatePath = props.appLambdaStack.StackTemplate,
                    StackName = "appLambdaDeploymentStack",
                    AdminPermissions = true,
                    ParameterOverrides = props.appLambdaStack.LambdaCode.Assign(lambdaBuildOutput.S3Location), 
                    ExtraInputs = new[] {lambdaBuildOutput},
                    Role = "role",
                    DeploymentRole = "deployRole"
                }),
            }
        }
    }
});

还有更多步骤，但它们不相关。

所以你可以看到我将 ParameterOverrides 应用到 props.appLambdaStack.LambdaCode.Assign(lambdaBuildOutput.S3Location) 这似乎没问题，因为当创建 lambda 时，它指定了大小，它与lambda 应该是，但是当我执行它时，我收到 "errorMessage": "Could not find the required 'QuickSight.Lambdas.SpiceRefresh.deps.json'. This file should be present at the root of the deployment package."

结果 Cloudformation 文件似乎也很好：

 "appLambdaF0BB8286": {
      "Type": "AWS::Lambda::Function",
      "Properties": {
        "Code": {
          "S3Bucket": {
            "Ref": "appLambdaSourceBucketNameParameter"
          },
          "S3Key": {
            "Ref": "appLambdaSourceObjectKeyParameter"
          }
        },
        "Handler": "Constants.Lambda.LambdaHandler",  //same as the constant in c#

        //Rest of the properties
    }
}

我在创建 post 之前进行了检查，大多数人都对处理程序有疑问。不幸的是，如果我手动下载 appLambdaSourceBucketNameParameter、appLambdaSourceObjectKeyParameter 中的对象并将其上传到 lambda，它会完美运行。我认为这将排除我的问题。

知道哪里出了问题吗？

Answer 1

找到解决方案。

问题是我在工件中 returning lambda .zip

["files"] = new[]
{
    "app/src/Lambdas/app.Lambdas.Action/bin/Release/netcoreapp2.1/app.Lambdas.Action.zip",
}

但我真正需要的是 return lambda 的二进制文件。（发布文件夹）

["artifacts"] = new Dictionary<string, object> 
{
    ["base-directory"] = "app/src/Lambdas/app.Lambdas.Action/bin/Release/netcoreapp2.1/publish",
    ["files"] = new[] { "**.*" }
}

没有其他改变，而且它起作用了。

Cloudformation 翻译：

在我导出之前 artifact::app.Lambdas.Action.zip 然后 AWS 试图找到二进制文件。现在正在导出 artifact::**.*，所以所有文件。
