创建Docker客户端import com.github.dockerjava.api.DockerClient;
import com.github.dockerjava.api.DockerClientBuilder;
DockerClient dockerClient = DockerClientBuilder.getInstance()
.withDockerHost("tcp://localhost:2375")
.withDockerCertPath("/path/to/cert")
.withApiVersion("1.41")
.build();
通过withDockerHost()方法设置了Docker守护进程的连接地址,withDockerCertPath()方法设置了TLS证书的路径,withApiVersion()方法设置了Docker API的版本。最后,通过调用build()方法构建了一个DockerClient对象。DockerClientBuilder类是用于构建和配置DockerClient对象的构建器类。它提供了一组方法,用于设置与Docker守护进程通信所需的参数和配置。import com.github.dockerjava.api.command.BuildImageResultCallback;
String dockerfilePath = "/path/to/dockerfile";
String imageName = "my-image";
String imageTag = "latest";
// 堆代码 duidaima.com
dockerClient.buildImageCmd()
.withDockerfile(new File(dockerfilePath))
.withTags(Collections.singleton(imageName + ":" + imageTag))
.exec(new BuildImageResultCallback())
.awaitCompletion();
withDockerfile(new File(dockerfilePath)):指定Dockerfile的路径,用于构建镜像。withProgressHandler(progressHandler):设置用于处理构建镜像进度的ProgressHandler。
import com.github.dockerjava.api.command.CreateContainerResponse;
import com.github.dockerjava.api.model.Bind;
import com.github.dockerjava.api.model.PortBinding;
import com.github.dockerjava.api.model.Volume;
String imageName = "my-image";
String containerName = "my-container";
int hostPort = 8080;
int containerPort = 80;
String volumeHostPath = "/host/path";
String volumeContainerPath = "/container/path";
CreateContainerResponse container = dockerClient.createContainerCmd(imageName)
.withName(containerName)
.withPortBindings(new PortBinding(
new Binding(null, null, hostPort),
new ExposedPort(containerPort)))
.withBinds(new Bind(volumeHostPath, new Volume(volumeContainerPath)))
.exec();
在上述代码中,imageName表示要使用的镜像的名称,containerName表示要创建的容器的名称。hostPort和containerPort分别表示主机端口和容器端口,用于进行端口映射。volumeHostPath和volumeContainerPath表示主机路径和容器路径,用于挂载卷。其中,CreateContainerResponse对象,包含了有关新创建容器的信息,比如容器的ID、名称等。以便接下来的启动停止容器等操作。dockerClient.startContainerCmd(container.getId()).exec();停止和删除容器
dockerClient.stopContainerCmd(container.getId()).exec(); dockerClient.removeContainerCmd(container.getId()).exec();在上述代码中,container.getId()获取到的是容器的ID。
