使用 sam deploy

使用 Amazon Serverless Application Model 命令行界面 (Amazon SAM CLI) sam deploy 命令将无服务器应用程序部署到 Amazon Web Services 云。

先决条件

要使用 sam deploy，请完成以下操作安装 Amazon SAM CLI。

我们建议您在使用 sam deploy 之前初步了解以下主题：

使用 sam deploy 部署应用程序

首次部署无服务器应用程序时，请使用 --guided 选项。Amazon SAM CLI 会指导您完成交互式流程，以配置应用程序的部署设置。

在部署之前验证更改

您可以将 Amazon SAM CLI 配置为显示 Amazon CloudFormation 变更集并在部署之前要求进行确认。

在部署过程中指定其他参数

您可以在部署时指定要配置的其他参数值。若要这样做，只需在部署过程中修改 Amazon SAM 模板并配置参数值。

配置 Lambda 函数的代码签名

您可以在部署时配置 Lambda 函数的代码签名。若要这样做，只需在部署过程中修改 Amazon SAM 模板并配置代码签名。

最佳实践

sam deploy 的选项

以下是 sam deploy 的常用选项：有关全部选项的列表，请参阅 sam deploy。

使用有指导的交互式流程部署应用程序

使用 --guided 选项通过交互式流程配置应用程序的部署设置。以下是 示例：

$ sam deploy --guided

应用程序的部署设置保存在项目的 samconfig.toml 文件中。要了解更多信息，请参阅配置项目设置。

故障排除

要对 Amazon SAM CLI 进行故障排除，请参阅 Amazon SAM CLI 故障排除。

示例

部署包含打包为 .zip 文件存档的 Lambda 函数的 Hello World 应用程序

有关示例，请参阅 Hello World 应用程序教程中的第 3 步：将应用程序部署到 Amazon Web Services 云。

部署包含打包为容器映像的 Lambda 函数的 Hello World 应用程序

首先，使用 sam init 创建 Hello World 应用程序。在交互式流程中，选择 Python3.9 运行时和 Image 包类型。

$ sam init

        ...
Runtime: 16

What package type would you like to use?
        1 - Zip
        2 - Image
Package type: 2

Based on your selections, the only dependency manager available is pip.
We will proceed copying the template using pip.

Commands you can use next
=========================
[*] Validate SAM template: sam validate
[*] Invoke Function: sam local invoke
[*] Test Function in the Cloud: sam sync --stack-name {{stack-name}} --watch
[*] Deploy: sam deploy --guided

然后，运行 sam deploy --guided 部署应用程序。Amazon SAM CLI 会指导我们配置部署设置。然后，Amazon SAM CLI 会将应用程序部署到 Amazon Web Services 云。

sam-app $ sam deploy --guided

Configuring SAM deploy
======================

        Looking for config file [samconfig.toml] :  Found
        Reading default arguments  :  Success

        Setting default arguments for 'sam deploy'
        =========================================
        Stack Name [sam-app]: ENTER
        AWS Region [us-west-2]: ENTER
        #Shows you resources changes to be deployed and require a 'Y' to initiate deploy
        Confirm changes before deploy [Y/n]: ENTER
        #SAM needs permission to be able to create roles to connect to the resources in your template
        Allow SAM CLI IAM role creation [Y/n]: ENTER
        #Preserves the state of previously provisioned resources when an operation fails
        Disable rollback [y/N]: ENTER
        HelloWorldFunction may not have authorization defined, Is this okay? [y/N]: y
        Save arguments to configuration file [Y/n]: ENTER
        SAM configuration file [samconfig.toml]: ENTER
        SAM configuration environment [default]: ENTER

        Looking for resources needed for deployment:

        Managed S3 bucket: aws-sam-cli-managed-default-samclisourcebucket-1a4x26zbcdkqr
        A different default S3 bucket can be set in samconfig.toml and auto resolution of buckets turned off by setting resolve_s3=False

        Parameter "stack_name=sam-app" in [default.deploy.parameters] is defined as a global parameter [default.global.parameters].
        This parameter will be only saved under [default.global.parameters] in /Users/.../sam-app/samconfig.toml.

        Saved arguments to config file
        Running 'sam deploy' for future deployments will use the parameters saved above.
        The above parameters can be changed by modifying samconfig.toml
        Learn more about samconfig.toml syntax at 
        https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-config.html
