      public Builder()

  • Method Details

    • entry

      @Stability(Experimental) public GoFunctionProps.Builder entry(String entry)
      Sets the value of GoFunctionProps.getEntry()
      Parameters:
      entry - The path to the folder or file that contains the main application entry point files for the project. This parameter is required. This accepts either a path to a directory or file.

      If a directory path is provided then it will assume there is a Go entry file (i.e. main.go) and will construct the build command using the directory path.

      For example, if you provide the entry as: 

                    entry: 'my-lambda-app/cmd/api'

      Then the go build command would be: 

                    `go build ./cmd/api`

      If a path to a file is provided then it will use the filepath in the build command.

      For example, if you provide the entry as: 

                    entry: 'my-lambda-app/cmd/api/main.go'

      Then the go build command would be: 

                    `go build ./cmd/api/main.go`
      Returns:
      this

    • logGroup

      @Stability(Stable) public GoFunctionProps.Builder logGroup(ILogGroup logGroup)
      Sets the value of FunctionOptions.getLogGroup()
      Parameters:
      logGroup - The log group the function sends logs to. By default, Lambda functions send logs to an automatically created default log group named /aws/lambda/. However you cannot change the properties of this auto-created log group using the AWS CDK, e.g. you cannot set a different log retention.

      Use the logGroup property to create a fully customizable LogGroup ahead of time, and instruct the Lambda function to send logs to it.

      Providing a user-controlled log group was rolled out to commercial regions on 2023-11-16. If you are deploying to another type of region, please check regional availability first.

      Returns:
      this

    • logRetention

      @Stability(Stable) public GoFunctionProps.Builder logRetention(RetentionDays logRetention)
      Sets the value of FunctionOptions.getLogRetention()
      Parameters:
      logRetention - The number of days log events are kept in CloudWatch Logs. When updating this property, unsetting it doesn't remove the log retention policy. To remove the retention policy, set the value to INFINITE.

      This is a legacy API and we strongly recommend you move away from it if you can. Instead create a fully customizable log group with logs.LogGroup and use the logGroup property to instruct the Lambda function to send logs to it. Migrating from logRetention to logGroup will cause the name of the log group to change. Users and code and referencing the name verbatim will have to adjust.

      In AWS CDK code, you can access the log group name directly from the LogGroup construct: 

                           import software.amazon.awscdk.services.logs.*;
                     
                     LogGroup myLogGroup;
                     
                     myLogGroup.getLogGroupName();
      Returns:
      this

    • logRetentionRetryOptions

      @Stability(Stable) public GoFunctionProps.Builder logRetentionRetryOptions(LogRetentionRetryOptions logRetentionRetryOptions)
      Sets the value of FunctionOptions.getLogRetentionRetryOptions()
      Parameters:
      logRetentionRetryOptions - When log retention is specified, a custom resource attempts to create the CloudWatch log group. These options control the retry policy when interacting with CloudWatch APIs.

      This is a legacy API and we strongly recommend you migrate to logGroup if you can. logGroup allows you to create a fully customizable log group and instruct the Lambda function to send logs to it.

      Returns:
      this

    • logRetentionRole

      @Stability(Stable) public GoFunctionProps.Builder logRetentionRole(IRole logRetentionRole)
      Sets the value of FunctionOptions.getLogRetentionRole()
      Parameters:
      logRetentionRole - The IAM role for the Lambda function associated with the custom resource that sets the retention policy. This is a legacy API and we strongly recommend you migrate to logGroup if you can. logGroup allows you to create a fully customizable log group and instruct the Lambda function to send logs to it.
      Returns:
      this

    • memorySize

      @Stability(Stable) public GoFunctionProps.Builder role(IRole role)
      Sets the value of FunctionOptions.getRole()

      role - Lambda execution role. This is the role that will be assumed by the function upon execution. It controls the permissions that the function will have. The Role must be assumable by the 'lambda.amazonaws.com' service principal.

      The default Role automatically has permissions granted for Lambda execution. If you provide a Role, you must add the relevant AWS managed policies yourself.
