1、启动容器

/**
     * 启动容器
     * @param name 容器名称或Id
     * @return
     */
    public static ObjectVo startDocker(String name){

        ObjectVo vo = new ObjectVo();
        if (StringUtils.isBlank(name)){
            vo.setCode(0);
            vo.setMsg("参数不能为空");
            vo.setObject(null);
            return vo;
        }

        String url = origin + "/containers/" + name + "/start";
        try {
            Response response = OKHttpUtil.doSyncPost(url, null);
            if (null != response) {
                vo.setCode(response.code());
                vo.setMsg(response.message());
                vo.setObject(response.body().string());
            }else{
                vo.setCode(0);
                vo.setMsg("请求出错，没有返回结果");
            }

        } catch (IOException e) {
            // TODO Auto-generated catch block
            vo.setCode(0);
            vo.setMsg("请求出错，没有返回结果");
            vo.setObject(null);
            e.printStackTrace();
        }
        return vo;
    }

状态码，ObjectVo.code可与其对比

    204 – no error
    304 – container already started
    404 – no such container
    500 – server error

2、ObjectVo代码

@Data
public class ObjectVo {
    
    private Integer code;
    private String msg;
    private Object object;

}

3、http请求

/**
     * 同步实现POST方式请求
     * @param url
     * @param params
     * @return
     * @throws IOException
     */
    public static Response doSyncPost(String url, Map<String, String> params) throws IOException{
        if (StringUtils.isBlank(url)) {
            return null;
        }
        FormBody.Builder builder = new FormBody.Builder();
        Request request = null;
        if (null != params && params.size() > 0) {
            for (Map.Entry<String, String> entry : params.entrySet()) {
                String value;
                if (null == entry.getValue()) {
                    value = "";
                }else{
                    value = entry.getValue();
                }
                builder.add(entry.getKey(), value);
            }
            RequestBody requestBody = builder.build();
            request = new Request.Builder().url(url).post(requestBody).build();
        }else{
            request = new Request.Builder().url(url).post(RequestBody.create(null, "")).build();
        }

        OkHttpClient client = new OkHttpClient.Builder()
                .connectTimeout(15, TimeUnit.SECONDS)
                .readTimeout(15, TimeUnit.SECONDS)
                .build();
        Call call = client.newCall(request);
        Response response = call.execute();
        return response;
    }
