Invoke Lambda From AWS Console
Welcome to CloudAffaire and this is Debjeet.
In the last blog post, we have created a deployment package for our lambda function.
In this blog post, we are going to execute the lambda function from the console. So far in this lambda blog series, we have executed our lambda function automatically using events from other service or manually using AWS CLI. In this blog post, we will execute the lambda directly from AWS lambda console.
Invoke Lambda From AWS Console:
Step 1: Login to AWS console and navigate to ‘Lambda’.
Step 2: Click on the function name.
Step 3: In the upper right pane, click ‘Configure test events’.
Step 4: Create an event for the lambda function using below JSON and click ‘Create’.
Note: Since our lambda function has been created with the trigger on S3 ‘create object’. Our function excepts the bucket and object name in the form of JSON. Hence in order to manually invoke the function, we are defining the bucket and object name in myevents.
Next, we are going to invoke our function
Step 5: Select ‘myevents’ from drop-down and click ‘Test’.
Observe: Though we have not uploaded any object in S3 bucket, our function executed successfully and we can check the log in lambda console itself.

Hope you have enjoyed this article. So far we have used push based (S3 for example) triggers for our lambda function. In the next blog post, we will configure the poll based trigger for Lambda function.
