About Speko Technologies

Speko was born out of a vision. We believed that cloud technology through AWS would be the future of cloud computing. As we worked toward that goal, we grew our team of motivated experts and began to actually work and improve upon our ideas.

We wanted to share our work with the world, so we started to release tools we have built under MIT licensing. Learn more at https://www.speko.io

Getting Started

Prerequisites

Make sure you have the following installed before starting:

• ruby
• npm
• serverless

The IAM role that is deploying the lambda will need the following permissions:

acm:ListCertificates                *
apigateway:GET                      /domainnames/*
apigateway:GET                      /domainnames/*/basepathmappings
apigateway:DELETE                   /domainnames/*
apigateway:POST                     /domainnames
apigateway:POST                     /domainnames/*/basepathmappings
apigateway:PATCH                    /domainnames/*/basepathmapping
cloudformation:GET                  *
cloudfront:UpdateDistribution       *
route53:ListHostedZones             *
route53:ChangeResourceRecordSets    hostedzone/{HostedZoneId}
route53:GetHostedZone               *
route53:ListResourceRecordSets      *
iam:CreateServiceLinkedRole         arn:aws:iam::${AWS::AccountId}: role/aws-service-role/ops.apigateway.amazonaws.com/AWSServiceRoleForAPIGateway
