Kubespray's roadmap

Kubeadm

• Switch to kubeadm deployment as the default method after some bugs are fixed:
  • Support for basic auth
  • cloudprovider cloud-config mount #484

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)
• to be discussed, a way to provide the inventory
• self deployment of the node from inside a container #321

Provisioning and cloud providers

• Terraform to provision instances on GCE, AWS, Openstack, Digital Ocean, Azure
• On AWS autoscaling, multi AZ
• On Azure autoscaling, create loadbalancer #297
• On GCE be able to create a loadbalancer automatically (IAM ?) #280
• TLS boostrap support for kubelet (covered by kubeadm, but not in standard deployment) #234 (related issues: https://github.com/kubernetes/kubernetes/pull/20439
  https://github.com/kubernetes/kubernetes/issues/18112)

Tests

• Run kubernetes e2e tests
• Test idempotency on single OS but for all network plugins/container engines
• single test on AWS per day
• test scale up cluster: +1 etcd, +1 master, +1 node
• Reorganize CI test vars into group var files

Lifecycle

• Upgrade granularity: select components to upgrade and skip others

Networking

• Opencontrail
• Consolidate network_plugins and kubernetes-apps/network_plugins

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

Monitoring

• Heapster / Grafana ....
• Prometheus

Others

Dashboards:

• kubernetes-dashboard
• Fabric8

• Refactor downloads so it all runs in the beginning of deployment
• Make bootstrapping OS more consistent
• consul -> if officially supported by k8s
• flex volumes options (e.g. torrus support) #312
