docker配置远程启动

https://www.cnblogs.com/senior-shef/p/17722219.htmlhttps://www.cnblogs.com/senior-shef/p/17722219.html

前提需要docker开启通信功能，有多种开启方式，我使用的是修改注册服务时的配置文件docker.service:

vim /usr/lib/systemd/system/docker.service

ExecStart  添加远程Api启动命令  
-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375

[Unit]

[Service]

Type=notify

ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375

创建client类

package cn.fnii.common.docker;

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

import com.github.dockerjava.core.DockerClientConfig;
import com.github.dockerjava.transport.DockerHttpClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

import java.time.Duration;

@Component
public class BaseDockerClientProxy {
    private DockerClient dockerClient;

    @Value("${docker.host}")
    private String serverUrl;

    @Value("${docker.registry.url}")
    private String registryUrl;

    @Value("${docker.registry.user}")
    private String registryUser;

    @Value("${docker.registry.pass}")
    private String registryPass;



    @Autowired
    public void setDockerClient() {
        // 这里就是获取dockerClient的方法了
        DockerClientConfig config = DefaultDockerClientConfig.createDefaultConfigBuilder()
            .withDockerHost(serverUrl)
//            .withDockerTlsVerify(true)
//            .withDockerCertPath("/home/user/.docker")
            .withRegistryUsername(registryUser)
            .withRegistryPassword(registryPass)
//            .withRegistryEmail(registryMail)
            .withRegistryUrl(registryUrl)
            .build();

        dockerClient = DockerClientBuilder.getInstance(config).build();
    }

    public DockerClient getDockerClient() {
        return dockerClient;
    }

}

yml配置

docker:
  host: tcp://172.171.16.232:2375
  registry:
    url: harbor.nl.com
    user: admin
    pass: XXXX

测试docker的查询和上传镜像

测试类

@Slf4j
@SpringBootTest
@ActiveProfiles("dev")
public class DockerTest {

    @Autowired
    private BaseDockerClientProxy baseDockerClientProxy;

    @Test
    public void test1() {
        List<Image> exec = baseDockerClientProxy.getDockerClient().listImagesCmd().exec();
        for (int i = 0; i < exec.size(); i++) {
            System.out.println(exec.get(i).getRepoTags());
        }
    }


    @Test
    public void test2() {
        PushImageResultCallback exec = baseDockerClientProxy.getDockerClient().pushImageCmd("harbor.nl.com/demo/test:1").exec(new PushImageResultCallback());
        exec.awaitSuccess();
        exec.toString();
    }


}
