aws-oidc-provider-github-actions

This repo contains a cloudformation template used to setup the OIDC provider and roles for Github actions. The roles are added via nested stacks. To add more roles simply copy the following section of template.yml and edit the top level indentifier, in this case roleRepo1, and RepositoryName under Parameters.

  roleRepo1:
    Type: AWS::CloudFormation::Stack
    Properties:
      TemplateURL: role.yml
      Parameters:
        GitHubOrg: !Ref GitHubOrg
        RepositoryName: my-repo-1
        OIDCProviderArn: !Ref GithubOidc

Also copy the Output section below and edit as needed...

roleRepo1:
    Value: !GetAtt roleRepo1.Outputs.Role
    Export:
      Name: !Sub "${AWS::StackName}-roleRepo1"

You can then create another stack to define your policies, attaching them to these roles as needed by importing the values exported by this stack. Then use configure-aws-credentials action to get temporary creds in your workflow.
