Question

我是docker的新手，我想使用java客户端启动docker容器，

我尝试https://github.com/docker-java/docker-java如下

package containers.launch_containers;

import com.github.dockerjava.api.DockerClient;
import com.github.dockerjava.core.DockerClientBuilder;

public class StartContainers{
     DockerClient dockerClient;

    public StartContainers() {
        startContainers();
    }

    public void startContainers() {
           try {

                dockerClient = DockerClientBuilder.getInstance("tcp://127.0.0.1:2375").build();
                //starting the container of hello-world 
                dockerClient.startContainerCmd("hello-world").exec();


    }catch(Exception ex)
           {
             ex.printStackTrace();
           }
    }

    public static void main(String args[])
    {
        StartContainers startContainers=new StartContainers();
    }   
}

在bashrc中设置所需的配置

export DOCKER_HOST = tcp：//127.0.0.1：2375

export DOCKER_OPTS =＆＃34; -H tcp：//127.0.0.1：2375 -H   UNIX：///var/run/docker.sock"

localhost中的Docker镜像

我有这个例外

javax.ws.rs.ProcessingException： org.apache.http.conn.HttpHostConnectException：连接到 127.0.0.1:2375 [/127.0.0.1]失败：连接被拒绝（连接被拒绝）at org.glassfish.jersey.apache.connector.ApacheConnector.apply（ApacheConnector.java:481）在 org.glassfish.jersey.client.ClientRuntime.invoke（ClientRuntime.java:252）在 org.glassfish.jersey.client.JerseyInvocation $ 1.call（JerseyInvocation.java:684）在 org.glassfish.jersey.client.JerseyInvocation $ 1.call（JerseyInvocation.java:681）在org.glassfish.jersey.internal.Errors.process（Errors.java:315）at org.glassfish.jersey.internal.Errors.process（Errors.java:297）at org.glassfish.jersey.internal.Errors.process（Errors.java:228）at org.glassfish.jersey.process.internal.RequestScope.runInScope（RequestScope.java:444）在 org.glassfish.jersey.client.JerseyInvocation.invoke（JerseyInvocation.java:681）在 org.glassfish.jersey.client.JerseyInvocation $ Builder.method（JerseyInvocation.java:437）在 org.glassfish.jersey.client.JerseyInvocation $ Builder.post（JerseyInvocation.java:343）在 com.github.dockerjava.jaxrs.StartContainerCmdExec.execute（StartContainerCmdExec.java:29）在 com.github.dockerjava.jaxrs.StartContainerCmdExec.execute（StartContainerCmdExec.java:12）在 com.github.dockerjava.jaxrs.AbstrSyncDockerCmdExec.exec（AbstrSyncDockerCmdExec.java:23）在 com.github.dockerjava.core.command.AbstrDockerCmd.exec（AbstrDockerCmd.java:35）在 com.github.dockerjava.core.command.StartContainerCmdImpl.exec（StartContainerCmdImpl.java:46）在 containers.launch_containers.StartContainers.startContainers（StartContainers.java:18）在 containers.launch_containers.StartContainers。（StartContainers.java:10）在 containers.launch_containers.StartContainers.main（StartContainers.java:29）

我解决了这个问题，我应该得到如下的容器ID

Function AddToArray(ys) As String()
Dim a() As String
Dim size As Integer
Dim i As Integer
Dim sh As Worksheet
Dim rw As Range
size = 0
ReDim Preserve a(size)
For Each rw In sh.Rows
    If Match(sh.Cells(rw.Row, 1), s, column) = True Then
        ??

size = size + 1
End Function
