Docker Remote api对docker操作-----启动容器

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;
	}
