## Create an IAM EC2 instance role and profile
As we'll be using [Amazon S3 object storage](#amazon-s3-object-storage), our EC2 instances need to have read, write, and list permissions for our S3 buckets. To avoid embedding AWS keys in our GitLab config, we'll make use of an [IAM Role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html) to allow our GitLab instance with this access. We'll need to create an IAM policy to attach to our IAM role:

Now that we have our EC2 instance ready, follow the [documentation to install GitLab and set up Gitaly on its own server](../../administration/gitaly/index.md#running-gitaly-on-its-own-server). Perform the client setup steps from that document on the [GitLab instance we created](#install-gitlab) above.
