Question #: 343
Topic #: 1

[All AWS Certified DevOps Engineer - Professional DOP-C02 Questions]

A company uses an AWS CodeArtifact repository to store Python packages that the company developed internally. A DevOps engineer needs to use AWS CodeDeploy to deploy an application to an Amazon EC2 instance. The application uses a Python package that is stored in the CodeArtifact repository. A BeforeInstall lifecycle event hook will install the package.

The DevOps engineer needs to grant the EC2 instance access to the CodeArtifact repository.

Which solution will meet this requirement?

A. Create a service-linked role for CodeArtifact. Associate the role with the EC2 instance. Use the aws codeartifact get-authorization-token CLI command on the instance.
B. Configure a resource-based policy for the CodeArtifact repository that allows the ReadFromRepository action for the EC2 instance principal.
C. Configure ACLs on the CodeArtifact repository to allow the EC2 instance to access the Python package.
D. Create an instance profile that contains an IAM role that has access to CodeArtifact. Associate the instance profile with the EC2 instance. Use the aws codeartifact login CLI command on the instance.

B. Configure a resource-based policy for the CodeArtifact repository: Issue: CodeArtifact repositories do not support resource-based policies (unlike S3 buckets or SNS topics). Access to CodeArtifact is controlled entirely through IAM policies attached to roles or users, making this option invalid.

just like other resource policies, CodeArtifact uses resource-based permissions to control access. Resource-based permissions let you specify who has access to a repository and what actions they can perform on it. By default, only the repository owner has access to a repository so implicit deny unless you apply a policy document that allows other IAM principals to access your repository. https://docs.aws.amazon.com/codeartifact/latest/ug/repo-policies.html

That is not saying that "specifically" you can not use IBPs, IBPs are prefered when you want to give individual access

IAM role with CodeArtifact permissions: You need an IAM role attached to the EC2 instance (via instance profile) that grants permission to read from CodeArtifact. aws codeartifact login sets up your Python environment (e.g., pip) to authenticate to the CodeArtifact repository using temporary credentials tied to the instance’s IAM role. This is the recommended approach to grant secure and scalable access to CodeArtifact from EC2 instances.

D. Create an instance profile that contains an IAM role that has access to CodeArtifact. Associate the instance profile with the EC2 instance. Use the aws codeartifact login CLI command on the instance. Explanation: To allow the EC2 instance to access the CodeArtifact repository, the EC2 instance must have the necessary IAM permissions to interact with AWS CodeArtifact. Here’s why option D is the best solution:
