Я создаю 3 гс для каждого Монго стручка:MongoDB replicaset на GKE не работает

И 4 услуги, 1 для каждого стручка плюс общее обслуживание:

После стручков создаются я бегу:
kubectl exec mongo-controller-1asd -it -- mongo
получить Монго оболочки, а затем запустить:
rs.initiate()
Все хорошо до сих пор и rs.conf() шоу:
rs0:OTHER> rs.conf()
{
"_id" : "rs0",
"version" : 1,
"protocolVersion" : NumberLong(1),
"members" : [
{
"_id" : 0,
"host" : "mongo-controller-1-ogwo7:27017",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
}
],
"settings" : {
"chainingAllowed" : true,
"heartbeatIntervalMillis" : 2000,
"heartbeatTimeoutSecs" : 10,
"electionTimeoutMillis" : 10000,
"getLastErrorModes" : {
},
"getLastErrorDefaults" : {
"w" : 1,
"wtimeout" : 0
},
"replicaSetId" : ObjectId("57a458a59d13b31c826e27cd")
}
}
Проблема начинается сразу же после того, как я добавить первый пэр
rs0:PRIMARY> rs.add({host:"mongo-2.default.svc.cluster.local", priority:1})
{ "ok" : 1 }
и проверить rs.status()
rs0:PRIMARY> rs.status()

Как вы видите, PRIMARY я был на изменениях SECONDARY, и новый сверстник, который я только что добавил, застрял в STARTUP. Я не могу добавить никаких дополнительных узлов, поскольку я застрял без основного и неработающего кластера.
