Question

我正在尝试编写Java代码来自动执行我执行的docker命令。我实际上是在创建一个mssql docker容器，然后想要在该容器中还原数据库备份。我可以使用docker命令来实现此目的，但无法使用docker-java复制它。

到目前为止，我已经实现了这一目标：

public static void main(String[] args) throws InterruptedException {
    BasicConfigurator.configure();
    DockerClient dockerClient
            = DockerClientBuilder.getInstance("tcp://localhost:1234").build();

    Volume volume1 = new Volume("/var/opt/mssql/backup"); //target

    //Network Creation
    CreateNetworkResponse networkResponse
            = dockerClient.createNetworkCmd()
            .withName("java-docker-mssql")
            .withDriver("bridge").exec();


    //Pulling an image
    dockerClient.pullImageCmd("microsoft/mssql-server-linux")
            .withTag("latest")
            .exec(new PullImageResultCallback())
            .awaitCompletion(30, TimeUnit.SECONDS);


    //Container Creation
    CreateContainerResponse container
            = dockerClient.createContainerCmd("microsoft/mssql-server-linux:2017-latest")
            .withPortBindings(PortBinding.parse("1433:1433"))
            .withEnv("ACCEPT_EULA=Y", "SA_PASSWORD=P@ssw0rd")
            .withVolumes(volume1)
            .withBinds(new Bind("/Users/robhit_saxena/Downloads/test-bind", volume1)) //is source
            .withName("mssql-from-java")
            .withNetworkMode("java-docker-mssql")
            .exec();

    //Starting a container
    dockerClient.startContainerCmd(container.getId()).exec();
    String containerId = container.getId();


    //Executing commands in a running container

    ExecCreateCmdResponse execCreateCmdResponse = dockerClient.execCreateCmd(container.getId())
            .withAttachStdout(true)
            .withAttachStderr(true)
            .withCmd("bash", "-c", "mkdir -p /var/opt/mssql/backup")
            .exec();


    dockerClient.execStartCmd(execCreateCmdResponse.getId()).exec(
            new ExecStartResultCallback(System.out, System.err)).awaitCompletion();

    ExecCreateCmdResponse execCreateCmdResponse1 = dockerClient.execCreateCmd(container.getId())
            .withAttachStdout(true)
            .withAttachStderr(true)
            .withCmd("bash", "-c", "/opt/mssql-tools/bin/sqlcmd -S localhost    -U SA -P 'P@ssw0rd'")
            .exec();


    dockerClient.execStartCmd(execCreateCmdResponse1.getId()).exec(
            new ExecStartResultCallback(System.out, System.err)).awaitCompletion();



}

但是，它无法连接并出现以下错误：

14253 [dockerjava-jaxrs-async-2] DEBUG org.apache.http.wire  - http-outgoing-4 << "[0x2][0x0][0x0][0x0][0x0][0x0][0x2][0x5]Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Login timeout expired.[\n]"

14253 [dockerjava-jaxrs-async-2] DEBUG org.apache.http.wire  - http-outgoing-4 << "Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : TCP Provider: Error code 0x2749.[\n]"

14253 [dockerjava-jaxrs-async-2] DEBUG org.apache.http.wire  - http-outgoing-4 << "Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : A network-related or instance-specific error has occurred while establishing a connection to SQL Server.

14254 [dockerjava-jaxrs-async-2] DEBUG com.github.dockerjava.jaxrs.JerseyDockerCmdExecFactory  - 14 * Client response received on thread dockerjava-jaxrs-async-2

注意：当我执行以下命令时，它会起作用：

docker exec -it mssql-from-java /opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P 'P@ssw0rd' -Q 'RESTORE FILELISTONLY FROM DISK = "/var/opt/mssql/backup/BSP-39251DBDump.bak"' | tr -s ' ' | grep ldf | cut -d ' ' -f 1

我什至尝试在创建容器时不使用网络并排除“ withNetworkMode”映射，但没有任何效果。

任何帮助将不胜感激！

谢谢！
