TiTiler as an AWS Serverless Application (SAM)

[vincentsarago]

Using https://github.com/lambgeo/titiler-layer (custom AWS Lambda layer built with a custom GDAL build) I've created an AWS SAM (Serverless Application Model) application which is publicly available over https://serverlessrepo.aws.amazon.com/applications/us-east-1/552819999234/TiTiler

This enable almost a one click deployment solution

FYI: I just updated the SAM application to the latest official TiTiler version (0.7.1)

When I try to deploy, I get User: arn:aws:iam::###2:user/### is not authorized to perform: serverlessrepo:GetApplication on resource: arn:aws:serverlessrepo:us-east-1:552819999234:applications/TiTiler. I'm totally new to Lambda, so is there something else I need to do?

@mradamcox I just tested with my account and It seems to work well, maybe you don't have enough permission with your AWS User to perform serverlessrepo:GetApplication. If you are using a company AWS account, reach out to your admin to update your role... if not I'm not sure what's going on

I did have to add some permissions to my IAM user. Seems like there wasn't a pre-made policy for serverlessrepo actions so I created a policy with the following and added it.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "serverlessrepo:*",
            "Resource": "*"
        }
    ]
}

I also had to add the AmazonAPIGatewayAdministrator policy. My user had a lot of permissions already, so this isn't an exhaustive list of what you need, but just wanted to mention this in case it's helpful for others.
