CloudFormation scenarios to create EC2 instance with IAM role attached - 'Resource initialization scenarios'
I've been struggling with this for a few days now and could really use some help... I'm trying to implement I'm integrating two systems and I'm trying to debug I'm running into an scenario while trying to create an EC2 instance with an IAM role attached using AWS CloudFormation..... When I deploy my stack, I'm receiving the behavior message: `Resource initialization failed`. I've double-checked that the IAM role exists and has the correct permissions, but I need to seem to figure out what's going wrong. Here's a snippet of my CloudFormation template: ```yaml Resources: MyEC2Instance: Type: AWS::EC2::Instance Properties: InstanceType: t2.micro ImageId: ami-0abcdef1234567890 IamInstanceProfile: !Ref MyIAMRole KeyName: my-key-pair MyIAMRole: Type: AWS::IAM::Role Properties: AssumeRolePolicyDocument: Version: '2012-10-17' Statement: - Effect: Allow Principal: Service: ec2.amazonaws.com Action: sts:AssumeRole Policies: - PolicyName: MyPolicy PolicyDocument: Version: '2012-10-17' Statement: - Effect: Allow Action: - s3:GetObject Resource: '*' ``` I also tried to create the IAM role separately and reference it in the CloudFormation template, but I still encounter the same behavior. Additionally, I checked if the EC2 service role has the necessary permissions, and it seems correct. I'm using the AWS CLI version 2.3.0 to deploy this stack. Can anyone provide insights on what might be causing this scenario or if there are additional parameters I need to include in the IAM role configuration? Any help would be greatly appreciated! I'd really appreciate any guidance on this. Has anyone dealt with something similar? I'm working on a mobile app that needs to handle this. I'd really appreciate any guidance on this. I'm using Yaml LTS in this project. What's the best practice here? I'm using Yaml 3.9 in this project. What's the best practice here?
