# 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
