Java API 操作Docker

java 调取docker api 进行操作docker，下面是具体的接口和实现类
我的具体接口地址为：http://ip:7004/v1.37 ，版本:v1.37

//查询容器列表
JSONArray query();
//创建容器
String create(String no , Map<String,Object> map);
//查询容器详细参数
String inspect(String id);
//启动容器
void start(String no,String id);
//停止容器
void stop(String no,String id);
//重启容器
void restart(String id);
//kill 容器
void kill(String id);
//暂停
void pause(String id);
//删除
void remove(String no,String id);
//获取运行状态
String getStatus(String id);

具体的实现类如下：

@Autowired
    RestTemplate restTemplate;

    @Autowired
    DockerConfig dockerConfig;

    @Autowired
    EvaluationService evaluationService;

    @Override
    public JSONArray query() {

                new ParameterizedTypeReference<JSONArray>(){});
        JSONArray result = resp.getBody();
        return result;
    }

    @Override
    public String create(String name,Map<String,Object> param) {
        String url = dockerConfig.getUrl() + "/containers/create?name="+name;
        HttpEntity<Map<String,Object>> entity = new HttpEntity<>(param);
        ResponseEntity<Map> resp = restTemplate.exchange(url, HttpMethod.POST,entity, new ParameterizedTypeReference<Map>(){});

            return map.get("Id");
        }else {
            log.error("容器创建失败：code={} message={}",resp.getStatusCodeValue(),map.get("message"));
            //状态修改ERR
            evaluationService.modifyStatusByNo(name, EvaluationState.Error);
