Significant Changes
Flannel
- Document risks and mitigations for container networking when etcd disappears and comes back with an empty data dir
- Flannel subnet range for a cell should be configurable
Scalability
- Policy server flakes when trying to add/delete several thousand policies
- As an operator I have metrics to help evaluate policy server performance
- As a space developer, I expect list policies to work when there are a lot of policies/apps
- Our docs include recommendations on scaling policy server instances and DB
- When policies are requested by ID, policy server does not query database for all policies
Chores
