iamsshsync synchronizes IAM users and their CodeCommit SSH keys to your EC2 instances every 10 minutes.

• It's not production ready.
• It gives all users sudo access.
• It doesn't filter users in IAM: it adds all of them.

• AWS CLI installed

• An instance profile that allows read access to IAM users, groups and SSH keys.

  For example:

  {
    "Sid": "AllowFetchAWSUserSSHKeys",
    "Effect": "Allow",
    "Action": [
      "iam:ListUsers",
      "iam:GetGroup",
      "iam:ListSSHPublicKeys",
      "iam:GetSSHPublicKey"
    ],
    "Resource": "*"
  }
