What is preventing us from migrating all existing project infrastructure over? Closure of all issues in this milestone means we are ready to begin migrating project infrastructure

Swag:

• we have an agreed upon prioritized backlog of infra to migrate
• we can generate and review billing reports at each wg-k8s-infra meeting (in detail)
• we can inventory what groups/roles we have and who is in them
• we can rebuild/redeploy cluster-based infra, and have done so at least twice
• we can use a k8s.gcr.io image promotion process for core kubernetes component images
