Couchbase Operator Binary Source / Checksums

Outside of using Helm or Openshift, the only way to deploy the Couchbase Operator is by downloading a compressed binary from this page: https://www.couchbase.com/downloads?family=open-source-kubernetes

Is the source for this tool publicly available? And if not, can checksums be provided for the package versions? We are building the utility into our deployment pipeline, and need to ensure consistency/security of the download.
