Building a new Scylla docker with the Agent installed works fine but requires some hacky things. ipify. Repositories. First we need to set the Agent HTTPS config in it's config file or the Agent will default to Scylla broadcast address which is not a local interface but networking defined by Kubernetes and only usable for outside clients calling in.
