Kargo'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 (kargo-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


 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 #234
(related issues: https://github.com/kubernetes/kubernetes/pull/20439 

https://github.com/kubernetes/kubernetes/issues/18112)


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.


Kargo-cli

Delete instances

kargo vagrant to setup a test cluster locally

kargo 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


Kargo 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
