## Hello Function - Solution
|
||
|
|
|
||
|
|
### Exercise
|
||
|
|
|
||
|
|
Create a basic AWS Lambda function that when given a name, will return "Hello <NAME>"
|
||
|
|
|
||
|
|
### Solution
|
||
|
|
|
||
|
|
#### Define a function
|
||
|
|
|
||
|
|
1. Go to Lambda console panel and click on `Create function`
|
||
|
|
1. Give the function a name like `BasicFunction`
|
||
|
|
2. Select `Python3` runtime
|
||
|
|
3. Now to handle function's permissions, we can attach IAM role to our function either by setting a role or creating a new role. I selected "Create a new role from AWS policy templates"
|
||
|
|
4. In "Policy Templates" select "Simple Microservice Permissions"
|
||
|
|
|
||
|
|
1. Next, you should see a text editor where you will insert a code similar to the following
|
||
|
|
|
||
|
|
#### Function's code
|
||
|
|
```
|
||
|
|
import json
|
||
|
|
|
||
|
|
|
||
|
|
def lambda_handler(event, context):
|
||
|
|
firstName = event['name']
|
||
|
|
return 'Hello ' + firstName
|
||
|
|
```
|
||
|
|
2. Click on "Create Function"
|
||
|
|
|
||
|
|
#### Define a test
|
||
|
|
|
||
|
|
1. Now let's test the function. Click on "Test".
|
||
|
|
2. Select "Create new test event"
|
||
|
|
3. Set the "Event name" to whatever you'd like. For example "TestEvent"
|
||
|
|
4. Provide keys to test
|
||
|
|
|
||
|
|
```
|
||
|
|
{
|
||
|
|
"name": 'Spyro'
|
||
|
|
}
|
||
|
|
```
|
||
|
|
5. Click on "Create"
|
||
|
|
|
||
|
|
#### Test the function
|
||
|
|
|
||
|
|
1. Choose the test event you've create (`TestEvent`)
|
||
|
|
2. Click on the `Test` button
|
||
|
|
3. You should see something similar to `Execution result: succeeded`
|
||
|
|
4. If you'll go to AWS CloudWatch, you should see a related log stream
