This document is meant to provide high-level but actionable objectives for future kube-aws deveploment. Please file an issue to make suggestions on this roadmap!
- Provide article walking users through:
- Setting up a cluster from scratch
- Using/enabling new features
- (Breaking changes)
- Drop deprecated configuration syntax and flags, options
- Revise this roadmap
- Node Pools
- Worker nodes optionally powered by Spot Fleet
- Clean cluster upgrades (preventing downtime, make sure they succeed)
- Kubernetes 1.5.1
- Auto-scaled kube-dns
- Self-hosted Calico
- Very limited, almost theoretical support for automatic reconfiguration of cluster-autoscaler
- Kubernetes 1.5.3
- Work-around the 16KB userdata limit in size
- Experimental support for
- Private subnets and NAT gateways for etcd, controller and worker nodes
- Deployments to existing subnets
- Rethink how node pools are implemented
- Kubernetes 1.5.4
- etcd: Automatic recovery from temporary etcd node failures
- etcd: Experimental support for an internal domain and custom hostnames for etcd nodes
- Kubernetes 1.6
- etcd: etcd v3 support #381
- It is enabled by default in 1.6: kubernetes/kubernetes#22448 (comment)
- etcd: Manual/Automatic recovery from permanent etcd node failures #417
- Cluster Auto Scaling
- Support for auto-scaling worker nodes via:
- Dynamic reconfiguration of cluster-autoscaler
- Automatic discovery of target node pools for cluster-autoscaler
- Requires much work on CA side
- Support for auto-scaling worker nodes via:
- Migrate from coreos-cloudinit to ignition for node bootstrapping
- YAML CloudFormation templates
- Bootkube switch
kube-awscan largely go into maintenance mode when k8s upgrades can be safely achieved on self-hosted clusters.
