您需要使用
--net=host选项运行hazelcast
docker映像。我测试了由hazelcast（https://hub.docker.com/r/hazelcast/hazelcast/）发布的Docker镜像，版本3.5.4，在AWS
EC2上有两个实例。我的Docker版本是
Docker version 1.9.1, build a34a1d5ec2上使用的ami
UbuntuServer 14.04 LTS (HVM), SSD Volume Type - ami-fce3c696，这是我的
hazelcast.xml：
<?xml version="1.0" encoding="UTF-8"?><hazelcast xsi:schemaLocation="http://www.hazelcast.com/schema/config hazelcast-config-3.5.xsd"xmlns="http://www.hazelcast.com/schema/config"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <group> <name>dev</name> <password>dev-pass</password> </group> <management-center enabled="false">http://localhost:8080/mancenter</management-center> <network> <port auto-increment="true" port-count="100">5701</port> <outbound-ports> <!-- Allowed port range when connecting to other nodes. 0 or * means use system provided port. --> <ports>0</ports> </outbound-ports> <join> <multicast enabled="false"> <multicast-group>224.2.2.3</multicast-group> <multicast-port>54327</multicast-port> </multicast> <tcp-ip enabled="false"> <interface>127.0.0.1</interface> <member-list> <member>127.0.0.1</member> </member-list> </tcp-ip> <aws enabled="true"> <access-key>your-acces-key</access-key> <secret-key>your-secret-key</secret-key> </aws> </join> <public-address>private-ip-address-of-ec2-instance</public-address> </network> <properties> <property name="hazelcast.local.localAddress">private-ip-address-of-ec2-instance</property> </properties></hazelcast>
这是我的docker命令，用于使用自定义配置文件运行hazelcast映像：
docker run --net=host -eJAVA_OPTS="-Dhazelcast.config=/configFolder/hazelcast.xml" -v~/configFolder:/configFolder -ti hazelcast/hazelcast
如果该
--net=host选项不起作用，请确保在hazelcast使用的安全组中，配置端口已作为入站端口打开。您还可以启用调试以查看有关通过ec2
Discovery发现的节点的更多详细信息。
