| # etcd on Kubernetes | ||
|
|
||
| This is an example setting up etcd as a set of pods and services running on top of kubernetes. Using: | ||
|
|
||
| ``` | ||
| $ kubectl create -f etcd.yml | ||
| services/etcd-client | ||
| pods/etcd0 | ||
| services/etcd0 | ||
| pods/etcd1 | ||
| services/etcd1 | ||
| pods/etcd2 | ||
| services/etcd2 | ||
| $ # now deploy a service that consumes etcd, such as vulcand | ||
| $ kubectl create -f vulcand.yml | ||
| ``` | ||
|
|
||
| TODO: | ||
|
|
||
| - create a replication controller like service that knows how to add and remove nodes from the cluster correctly | ||
| - use kubernetes secrets API to configure TLS for etcd clients and peers |
