Use the Invoke Lambda Function action to process Bamboo notifications, JIRA workflow transitions and JIRA Service Desk automation rule executions with AWS Lambda, which lets you run code without provisioning or managing servers:

You pay only for the compute time you consume - there is no charge when your code is not running. With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability. You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app.

Requirements

The Invoke Lambda Function action requires sufficient IAM permissions - an adequate IAM policy similar to the one provisioned by the Automation with AWS (Core) CloudFormation template might look as follows:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "lambda:GetAlias",
                "lambda:GetFunctionConfiguration",
                "lambda:GetPolicy",
                "lambda:InvokeFunction",
                "lambda:ListAliases",
                "lambda:ListFunctions",
                "lambda:ListVersionsByFunction"
            ],
            "Resource": "*",
            "Effect": "Allow",
            "Sid": "LambdaInvokeFunctionAndDiscoverFunctions"
        }
    ]
}

Refer to Overview of Managing Access Permissions to Your AWS Lambda Resources for details on how to create more granular/secure policies.

Configuration

To configure an Invoke Lambda Function action:

Complete the following settings:

Parameters

Specify the action parameters according to the following skeleton in JSON format – refer to lambda . invoke for details:

You typically only specify the FunctionName and Payload parameters, and not all parameters documented for lambda . invoke are applicable here (invocation-type and log-type are not meaningful, and outfile is not supported).

You can inject contextual variables into the remote action payload, refer to Entity Variables for details.

Invoke Lambda Function skeleton

{
    "FunctionName": "",
    "Payload": {},
    "Qualifier": "",
    "ClientContext": {}
}

Entity Variables

You can inject contextual workflow variables with workflow entities into the remote action payload template – currently available entities are:

JSON escaping requirements
If a parameter within the JSON formatted parameters template is a JSON structure in itself (e.g. the Lambda function payload), it needs to be escaped before adding it as a value - this has two implications:
custom content needs to be escaped, which can be achieved by Composing action payloads with utility functions, specifically the $util.escapeJson() function
variables with conflicting content (e.g. multi line variables like JIRA's $issue.fields.description or Bamboo's $notification.textEmailContent or JSON structures retrieved via JSONPath) need to be escaped twice, via $util.escapeJson($util.escapeJson(...)) - we are exploring options on how to make this easier in a future release
Invoke Lambda Function parameters example (escaped manually)
{ "FunctionName": "arn:aws:lambda:ap-southeast-2:123456789012:function:sample-AutomationWithAWSQuickstartLamb-1RRX37PWXZXLS", "Payload": "{ \"Event\":\"$event.simpleName\", \"Timestamp\": \"$event.timestamp\", \"TraceID\": \"$event.traceId\"}" }
Invoke Lambda Function parameters example (escaped with utility function)
{ "FunctionName": "arn:aws:lambda:ap-southeast-2:123456789012:function:sample-AutomationWithAWSQuickstartLamb-1RRX37PWXZXLS", "Payload": "$util.escapeJson('{ "Event": "$event.simpleName", "Timestamp": "$event.timestamp", "TraceID": "$event.traceId" }')" }
