orchestrator
supports these key-value stores:
orchestrator
supports master discovery by storing clusters' masters in KV.
"KVClusterMasterPrefix": "mysql/master",
"ConsulAddress": "127.0.0.1:8500",
"ZkAddress": "srv-a,srv-b:12181,srv-c",
"ConsulCrossDataCenterDistribution": true,
KVClusterMasterPrefix
is the prefix to use for master discovery entries. As example, your cluster alias is mycluster
and the master host is some.host-17.com
then you will expect an entry where:
- The Key is
mysql/master/mycluster
- The Value is
some.host-17.com:3306
Note: on ZooKeeper the key will automatically prefix with a /
if not already so.
In addition to the above, orchestrator
also breaks down the master entries and adds the follows (illustrating via example above):
mysql/master/mycluster/hostname
, value issome.host-17.com
mysql/master/mycluster/port
, value is3306
mysql/master/mycluster/ipv4
, value is192.168.0.1
mysql/master/mycluster/ipv6
, value is<whatever>
The /hostname
, /port
, /ipv4
and /ipv6
extensions are automatically added for any master entry.
If specified, ConsulAddress
indicates an address where a Consul HTTP service is available. If unspecified, no Consul access is attempted.
If specified, ZkAddress
indicates one or more ZooKeeper servers to connect to. Default port per server is 2181
. All the following are equivalent:
srv-a,srv-b:12181,srv-c
srv-a,srv-b:12181,srv-c:2181
srv-a:2181,srv-b:12181,srv-c:2181
See kv documentation for Consul specific settings.
