I have the configuration for the 3 masters:

master1

```auto
cluster.name: elasticsearch
node.master: true
node.data: false
node.name: "master1"
path.data: /data/data
path.logs: /data/log
bootstrap.memory_lock: true
transport.tcp.port: 9300
http.enabled: false
network.host: 0.0.0.0
gateway.recover_after_nodes: 4
gateway.expected_nodes: 5
discovery.zen.minimum_master_nodes: 2
discovery.zen.ping_timeout: 10s
discovery.zen.ping.unicast.hosts: ["es-master1:9300", "es-master2:9300", "es-master3:9300"]
path.repo: ["/mnt/backup/elasticsearch"]

```

master2

```auto
cluster.name: elasticsearch
node.master: true
node.data: false
node.name: "master2"
path.data: /data/data
path.logs: /data/log
bootstrap.memory_lock: true
transport.tcp.port: 9300
http.enabled: false
network.host: 0.0.0.0
gateway.recover_after_nodes: 4

```

master3

```auto
cluster.name: elasticsearch
node.master: true
node.data: false
node.name: "master3"
path.data: /data/data
path.logs: /data/log
bootstrap.memory_lock: true
transport.tcp.port: 9300
http.enabled: false
network.host: 0.0.0.0

gateway.expected_nodes: 5
discovery.zen.minimum_master_nodes: 2
discovery.zen.ping_timeout: 10s
discovery.zen.ping.unicast.hosts: ["es-master1:9300", "es-master2:9300", "es-master3:9300"]
path.repo: ["/mnt/backup/elasticsearch"]

```

When starting the elasticsearch i have the error:

```auto
[2020-02-24T17:05:56,121][INFO][o.e.n.Node] [master2] starting ...
[2020-02-24T17:05:56,377][INFO][o.e.t.TransportService] [master2] publish_address {172.30.0.10:9300}, bound_addresses {[::]:9300}

ERROR: [1] bootstrap checks failed

[2020-02-24T17:05:56,509][INFO][o.e.n.Node] [master2] stopped

```

NOTES:

- My docker run command have the flags : --detach --privileged
- Use simular jvm.options file ([https://github.com/pires/docker-elasticsearch/blob/5.6.0/config/jvm.options](https://github.com/pires/docker-elasticsearch/blob/5.6.0/config/jvm.options))

Can someone help me with this error? Thank you.
