无法从主机连接到 Docker Aerospike

Question

我在运行ning aerospike 服务器 docker。

$  docker run -d --name aerospike aerospike/aerospike-server
0ad3b2df67bd17f896e87ed119758d9af7fcdd9b82a8632828e01072e2c5673f

启动成功

$docker ps
CONTAINER ID        IMAGE                        COMMAND                
CREATED             STATUS              PORTS               NAMES
0ad3b2df67bd        aerospike/aerospike-server   "/entrypoint.sh asd"    
4 seconds ago       Up 2 seconds        3000-3003/tcp       aerospike

我使用以下命令找到了 docker 的 IP 地址。

$ docker inspect -f '{{.NetworkSettings.IPAddress }}' aerospike
172.17.0.2

当我尝试使用以下命令连接到 aql 时，它也成功了。

$ docker run -it aerospike/aerospike-tools aql -h  $(docker inspect -f 
'{{.NetworkSettings.IPAddress }}' aerospike)
 Aerospike Query Client
 Version 3.15.0.3
 C Client Version 4.2.0
 Copyright 2012-2017 Aerospike. All rights reserved.
 aql> select * from test.person
 0 rows in set (0.002 secs)

现在我正在尝试使用主机中的 java 客户端连接到 docker 中的 aerospike 服务器。

public class AerospikeDemo {
    public static void main(String []args) {

        AerospikeClient client = new AerospikeClient("172.17.0.2", 3000);
        Key key = new Key("test", "demo", "putgetkey");
        //Key key2 = new Key("1", "2", "3");
        Bin bin1 = new Bin("bin1", "value1");
        Bin bin2 = new Bin("bin2", "value2");
        Bin bin3 = new Bin("bin2", "value3");

        // Write a record
        client.put(null, key, bin1, bin2, bin3);

        // Read a record
        Record record = client.get(null, key);

        System.out.println("record is "+ record);
        System.out.println("record bins is " + record.bins);

        client.close();
      }
  }

当我运行上述程序时，出现以下错误 -

objc[3446]: Class JavaLaunchHelper is implemented in both 
/Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/bin/java (0x10f7b14c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x10f8794e0). One of the two will be used. Which one is undefined.

AerospikeClient("172.17.0.2", 3000) 和 AerospikeClient("localhost", 3000)

我都试过了

我在 Dockerfile 中看到端口 3000 暴露给主机，但我不确定为什么我无法在 docker 中使用 aerospike 服务器。

Answer 1

IP 172.17.0.2 只能在 Docker 内访问（因此您可以使用另一个容器进行连接）。如果您想从您的主机连接，您需要映射相应的端口。

docker run -d --name aerospike -p 3000:3000 aerospike/aerospike-server

之后您可以使用：

AerospikeClient client = new AerospikeClient("localhost", 3000);

无法从主机连接到 Docker Aerospike
