Configuring Lambda runtime management settings

You can configure runtime management settings using the Lambda console or the AWS Command Line Interface (AWS CLI).

Note

You can configure runtime management settings separately for each function version.

To configure how Lambda updates your runtime version (console)

1. Open the Functions page of the Lambda console.

2. Choose the name of a function.

3. On the Code tab, under Runtime settings, choose Edit runtime management configuration.

4. Under Runtime management configuration, choose one of the following:

   • To have your function update to the latest runtime version automatically, choose Auto.

   • To have your function update to the latest runtime version when you change the function, choose Function update.

   • To have your function update to the latest runtime version only when you change the runtime version ARN, choose Manual. You can find the runtime version ARN under Runtime management configuration. You can also find the ARN in the INIT_START line of your function logs.

   For more information about these options, see Runtime update modes.

5. Choose Save.

To configure how Lambda updates your runtime version (AWS CLI)

To configure runtime management for a function, run the put-runtime-management-config AWS CLI command. When using Manual mode, you must also provide the runtime version ARN.

aws lambda put-runtime-management-config \
  --function-name my-function \
  --update-runtime-on Manual \
  --runtime-version-arn arn:aws:lambda:us-east-2::runtime:8eeff65f6809a3ce81507fe733fe09b835899b99481ba22fd75b5a7338290ec1

You should see output similar to the following:

{
  "UpdateRuntimeOn": "Manual",
  "FunctionArn": "arn:aws:lambda:us-east-2:111122223333:function:my-function",
  "RuntimeVersionArn": "arn:aws:lambda:us-east-2::runtime:8eeff65f6809a3ce81507fe733fe09b835899b99481ba22fd75b5a7338290ec1"
}
