Question 1

How do you configured AWS CodePipeline with AWS OpsWorks?

Answer 1

Step 1: Create a stack, layer, and an instance in AWS OpsWorks Stacks
Step 2: Upload app code to an Amazon S3 bucket (can be zip)
Step 3: Add your app to AWS OpsWorks Stacks
Step 4: Create a pipeline in CodePipeline (add opsworks to deploy stage)
Step 5: Verifying the app deployment in AWS OpsWorks Stacks
Step 6 (Optional): Update the app code to see CodePipeline redeploy your app automatically
Step 7 (Optional): Clean up resources

Question 2

Where can you use intrinsic functions in CFN?

Answer 2

You can use intrinsic functions only in specific parts of a template. Currently, you can use intrinsic functions in resource properties, outputs, metadata attributes, and update policy attributes. You can also use intrinsic functions to conditionally create stack resources.

Question 3

What are intrinsic functions in CFN?

Answer 3

Built-in functions that help you manage your stacks. Use intrinsic functions in your templates to assign values to properties that are not available until runtime.

Examples:
Fn::Cidr
Fn::GetAtt
Fn::Join
Condition Functions
Ref
....

Question 4

What are the OpsWorks Stacks Lifecycle Events?

Answer 4

1. Setup
2. Configure
3. Deploy
4. Undeploy
5. Shutdown

OpsWorks only responds to the last event to avoid unnecessary processing. Unprocessed events are labeled “superseded.”

Question 5

What happens when you attach a load balancer to a layer in an OpsWorks stack?

Answer 5

1. Deregisters any currently registered instances.
2. Automatically registers the layer’s instances when they come online and deregisters instances when they go offline, including load-based and time-based instances.
3. Automatically starts routing requests to registered instances in their Availability Zones.
