This is a simplified version of the configs found in the Vitess repo: https://github.com/youtube/vitess/tree/master/examples/kubernetes Here we use a single script to start all of Vitess, since the aim is just to show the end result. The full tutorial on our site goes into much more detail on each step: http://vitess.io/getting-started/

# This is an example script that creates etcd clusters.
|
|
# Vitess requires a global cluster, as well as one for each cell.
|
|
#
|
|
# For automatic discovery, an etcd cluster can be bootstrapped from an
|
|
# existing cluster. In this example, we use an externally-run discovery
|
|
# service, but you can use your own. See the etcd docs for more:
|
|
# https://github.com/coreos/etcd/blob/v2.0.13/Documentation/clustering.md
