B) Configure a build trigger in CodePipeline
C) Use AWS CloudTrail
D) Use AWS IAM roles

A

C) AWS CodeCommit
D) AWS CodePipeline

A

A) AWS CodeBuild

21
Q

Where are artifacts in Code Pipeline Stored?

A

S3

22
Q

What are some possible sources for CodePipeline?

A

AWS ECR
AWS S3
Bitbucket
GitHub
GitLab

23
Q

What is the primary difference between using polling and events to trigger an action in AWS CodePipeline?

A) Polling checks for changes at regular intervals, while events provide real-time notifications.
B) Events require manual configuration, while polling is automatic.
C) Polling can only trigger Lambda functions, while events can trigger any AWS service.
D) Events are not supported by AWS CodePipeline.

A

Answer: A) Polling checks for changes at regular intervals, while events provide real-time notifications.

Explanation: Polling requires CodePipeline to check periodically for updates in the source repository, which can lead to slight delays. Events (e.g., using webhooks) enable immediate triggering of the pipeline when a change is detected, providing faster response times.

24
Q

You set up a CodePipeline that pulls code from GitHub. What is the advantage of using a webhook over polling in this setup?

A) Webhooks reduce the amount of API calls needed to check for updates.
B) Webhooks allow scheduled triggers at fixed intervals.
C) Polling is faster than webhooks in detecting changes.
D) Webhooks require AWS Lambda integration to work with CodePipeline.

A

Answer: A) Webhooks reduce the amount of API calls needed to check for updates.

Explanation: Webhooks provide real-time notifications to CodePipeline whenever a change is made, eliminating the need for continuous API calls. This reduces overhead and provides immediate triggering without the delay associated with polling.

25
Q

What are the permissions needed at the IAM level for the user to have manual approval access?

A

{
“Version”: “2012-10-17”,
“Statement”: [
{
“Effect”: “Allow”,
“Action”: [
“codepipeline:ListPipelines”
],
“Resource”: [
“*”
]
},
{
“Effect”: “Allow”,
“Action”: [
** “codepipeline:GetPipeline”,
“codepipeline:GetPipelineState”,
“codepipeline:GetPipelineExecution”
],
“Resource”: “arn:aws:codepipeline:us-east-2:80398EXAMPLE:MyFirstPipeline”
},
{
“Effect”: “Allow”,
“Action”: [
** “codepipeline:PutApprovalResult”
],
“Resource”: “arn:aws:codepipeline:us-east-2:80398EXAMPLE:MyFirstPipeline/MyApprovalStage/MyApprovalAction”
}
]
}

26
Q

What is the most important file that lives in CodeBuild?

A

buildspec.yml

27
Q

Where should the buildspect.yml be located?

A

At the root of your directory

28
Q

What are the main pieces of the buildspec.yml file?

A

Env - define env variables
* plaintext variables
* parameter-store: variables stored in SSM parameter store
* secrets-manager: variables stored in AWS Secret Manager
Phases - specify commands to run:
* install
* pre_build
* build
* post_build
Artifacts - what to upload to S3
Cache - files to cache

29
Q

True or False.
By default, CodeBuild containers are launched within your VPC and have access to resources in VPC.

A

False, by default CodeBuild containers are launched outside your VPC.

You can specify a VPC configuation to allow access to all VPC resources.

30
Q

Is it possible to add CodeBuild to CodePipeline without starting over?

A

Yes, you just have to change the primary source and uncheck ‘rebuild everytime a code change is pushed to this repo’. Essentially take it out of GitHub to use the CodePipeline trigger instead.

CodePipeline will be triggered with GitHub change, but and CodeBuild will be triggered downstream.

31
Q

What are some services you can deploy onto using CodeDeploy?

A

EC2 Instances, On-prem servers, Lambda functions, ECS Services

32
Q

What is CodeDeploy Agent?

A

The agent that runs the code deploy on the service (EC2, On Prem, Lambda, etc)

33
Q

What is artifact management?

A

storing and retreiving dependencies (software packages that depend on each other to be built)

34
Q

What is CodeArtifact?

A

A secure, scalable and cost-effective artifact management for software devlopment
