Kubespray's roadmap

Kubeadm

  • Propose kubeadm as an option in order to setup the kubernetes cluster. That would probably improve deployment speed and certs management #553

Self deployment (pull-mode) #320

  • the playbook would install and configure docker/rkt and the etcd cluster
  • the following data would be inserted into etcd: certs,tokens,users,inventory,group_vars.
  • a "kubespray" container would be deployed (kubespray-cli, ansible-playbook, kpm)
  • to be discussed, a way to provide the inventory
  • self deployment of the node from inside a container #321

Provisionning and cloud providers

Tests

  • Run kubernetes e2e tests
  • migrate to jenkins (a test is currently a deployment on a 3 node cluste, testing k8s api, ping between 2 pods)
  • Full tests on GCE per day (All OS's, all network plugins)
  • trigger a single test per pull request
  • single test with the Ansible version n-1 per day
  • Test idempotency on on single OS but for all network plugins/container engines
  • single test on AWS per day
  • test different achitectures : - 3 instances, 3 are members of the etcd cluster, 2 of them acting as master and node, 1 as node - 5 instances, 3 are etcd and nodes, 2 are masters only - 7 instances, 3 etcd only, 2 masters, 2 nodes
  • test scale up cluster: +1 etcd, +1 master, +1 node

Lifecycle

  • Adopt the kubeadm tool by delegating CM tasks it is capable to accomplish well #553
  • Drain worker node when upgrading k8s components in a worker node. #154
  • Drain worker node when shutting down/deleting an instance
  • Upgrade granularity: select components to upgrade and skip others

Networking

  • romana.io support #160
  • Configure network policy for Calico. #159
  • Opencontrail
  • Canal
  • Cloud Provider native networking (instead of our network plugins)

High availability

  • (to be discussed) option to set a loadbalancer for the apiservers like ucarp/packemaker/keepalived While waiting for the issue kubernetes/kubernetes#18174 to be fixed.

Kubespray-cli

  • Delete instances
  • kubespray vagrant to setup a test cluster locally
  • kubespray azure for Microsoft Azure support
  • switch to Terraform instead of Ansible for provisionning
  • update $HOME/.kube/config when a cluster is deployed. Optionally switch to this context

Kubespray API

  • Perform all actions through an API
  • Store inventories / configurations of mulltiple clusters
  • make sure that state of cluster is completely saved in no more than one config file beyond hosts inventory

Addons (with kpm)

Include optionals deployments to init the cluster:

Monitoring
  • Heapster / Grafana ....
  • Prometheus
Others
Dashboards:
  • kubernetes-dashboard
  • Fabric8
  • Tectonic
  • Cockpit
Paas like
  • Openshift Origin
  • Openstack
  • Deis Workflow

Others

  • remove nodes (adding is already supported)
  • being able to choose any k8s version (almost done)
  • rkt support #59
  • Review documentation (split in categories)
  • consul -> if officialy supported by k8s
  • flex volumes options (e.g. torrus support) #312
  • Clusters federation option (aka ubernetes) #329
