A multi-tenant authentication system facilitates packaging and installing of integrations for authentication services of system tenants. The integrations include cloud resources of one or more cloud services. In order to package an integration, the multi-tenant authentication system retrieves resource manifests for cloud resources from corresponding cloud services. The multi-tenant authentication system generates the resource manifests to describe the cloud resource and any dependencies of the cloud resource, and also generates a package manifest including instructions for using the resource manifests to install the corresponding integration. The multi-tenant authentication system further facilitates installation of integration packages for tenants of the multi-tenant authentication system. The multi-tenant authentication system communicates with cloud services associated with resource manifests to install corresponding cloud resources to consistently replicate integrations for different tenants.
