What is the best method to give privilege to an EC2 instance to access other AWS?
When you launch an Amazon EC2 instance, you can associate an AWS IAM role with the instance to give applications or CLI commands that run on the instance permissions that are defined by the role. When a role is associated with an instance, EC2 obtains temporary security credentials for the role you associated with the instance. It then makes those temporary credentials available to applications and CLI commands that run on the instance. Not only is using a role with EC2 in this way more secure than alternative ways of providing credentials to the instance, but it’s more convenient and easier to manage. Show
If an IAM user wants to launch an EC2 instance, you need to grant the EC2 For example, you might attach the following policy to a user. It gives the user full EC2 permissions, which includes the ability to launch instances. { "Version": "2012-10-17", "Statement": [{ "Effect":"Allow", "Action":["ec2:*"], "Resource":"*" }, { "Effect":"Allow", "Action":"iam:PassRole", "Resource":"arn:aws:iam::123456789012:role/S3Access" }] } Notice that the second statement is for the Why do users need this permission?The As with other IAM permissions, you can specify a wildcard (*) as the resource for the { "Version": "2012-10-17", "Statement": [{ "Effect":"Allow", "Action":["ec2:*"], "Resource":"*" }, { "Effect":"Allow", "Action":"iam:PassRole", "Resource":"arn:aws:iam::123456789012:role/DevTeam*" }] } You can also use a wildcard to indicate that the permission applies to all resources–in this case, that the user is allowed to associate any role with an instance: "Resource":"arn:aws:iam::123456789012:role/*" Using a wildcard like this can be appropriate if the user already has administrator-level permissions and if applications running on the instance require full AWS permissions. But if you’re creating a policy that includes the People sometimes ask why there is no
