Using AWS IAM roles in Octopus

Managing cloud provider credentials is a complex task due to the risk of unauthorized access, and IAM roles in AWS offer a solution by providing task-specific authorizations to instances like EC2. These roles can be created in the AWS IAM console, allowing specific services such as EC2 to assume the role, which can then be verified and utilized through the AWS CLI and other tools like Octopus Tentacles and Workers, enabling operations without sharing AWS credentials. The article also explains how to connect an EC2 instance as an Octopus Worker, allowing script execution and deployments using the instance's IAM role, and demonstrates configuring Kubernetes targets to use IAM roles for access, eliminating the need for direct AWS credential sharing. This process enhances security and simplifies credentials management, highlighting improvements with Octopus 2020.4.
