Service Discovery

GCE

No great service discovery story that I can find. The best approximation is their GCE compute instance metadata service, which can be used as a pseudo-Consul or etcd for discovering active services. This metadata can be used to construct FQDN's for Google's internal DNS service: https://cloud.google.com/compute/docs/internal-dns

Problem as I understand it

Deploying Salt:

• How to make minions aware of other minions. Cross-minion configuration.
• Proper ordering of salt states (i.e. Repo.highstate -> base.highstate -> manual stuff -> *.highstate)

Updating configurations:

• Merging new pillars during an RPM update.
• Adding/deleting minions from "inventory", handling configuration updates in other minions automatically
• A/B rollout of new configuration
