@Marvin I know Prefect deployments to an ECS work pool can have overrides to the base job template such as the task definition arn and the task execution role arn. I'm curious if it is also possible to specify an override for an STS AssumeRole operation so a task can be given access to perform AWS operations in a different AWS account from the one the worker is deployed to.

It seems that specific information about specifying an STS AssumeRole override for ECS tasks using Prefect is not directly available in the Prefect documentation. However, there are general insights on setting up IAM roles and permissions for ECS in conjunction with Prefect. From the excerpts, we can derive that: - IAM roles and permissions are important to configure when working with ECS and Prefect. - There is mention of creating an IAM role for managing project-specific policies, which suggests that assuming different roles could be possible. To achieve cross-account access via STS AssumeRole, AWS generally requires setting up appropriate IAM roles and policies. It is common for the ECS task definition to include the necessary AssumeRole configuration, but this is typically handled through AWS's infrastructure as code tools like Pulumi, Terraform, or CloudFormation, rather than directly through Prefect. It is likely that you would configure the AssumeRole operation as part of the AWS-specific infrastructure setup that includes your ECS task definitions, and Prefect would operate within that AWS configuration. For more detailed guidance on integrating Prefect with AWS ECS and cross-account permissions, it might be helpful to consult AWS documentation on IAM roles and AssumeRole, and how they interact with ECS tasks.
