Google运行-无法发送出站请求
Google运行-无法发送出站请求
提问于 2021-09-30 15:34:28
我在Google运行中部署了一个容器。这是一个在Spring和Java中构建的应用程序。
我向云运行容器公开了一个端点( REST控制器)，它进一步调用REST来访问外部端点，此时它就失败了。我从邮递员那里碰到了暴露的端点。
容器能够侦听传入的请求，甚至能够连接到Cloud。问题是-它不能击中外部API。
我甚至在防火墙中添加了一个出站规则，允许所有的流量，但没有成功。后来，尝试为防火墙打开日志，但没有生成日志。
有谁知道这里有什么问题吗？
请查看下面的日志和异常

在Spring引导中进行调用的代码
WebClient webClient =
WebClient.builder()
.defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
.build();
Mono<HDCanadaProdResp> webClientResponse =
webClient.get().uri(stockApiurl).retrieve().bodyToMono(HDCanadaProdResp.class);
webClientResponse.block();所有代码都在Docker容器中的本地系统中工作，不确定云运行的问题是什么。
这是Dockerfile

我更改了我使用WebClient API进行rest调用的spring代码，现在错误已经改变了。
旧码
WebClient webClient =
WebClient.builder()
.defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
.defaultHeader(HttpHeaders.ACCEPT_ENCODING, "gzip, deflate, br")
.defaultHeader(HttpHeaders.ACCEPT_LANGUAGE, "en-CA,en-US;q=0.7,en;q=0.3")
.defaultHeader(HttpHeaders.HOST, "www.homedepot.ca")
.build();
Mono<HDCanadaRecomProdResp> webClientResponse =
webClient.get().uri(prodApiurl).retrieve().bodyToMono(HDCanadaRecomProdResp.class);
return webClientResponse.block();新码
HttpComponentsClientHttpRequestFactory requestFactory =
new HttpComponentsClientHttpRequestFactory();
requestFactory.setConnectTimeout(60 * 1000);
requestFactory.setReadTimeout(60 * 1000);
RestTemplate restTemplate = new RestTemplate(requestFactory);
ResponseEntity<HDCanadaRecomProdResp> response = null;
try {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set(HttpHeaders.ACCEPT_ENCODING, "gzip, deflate, br");
headers.set(HttpHeaders.ACCEPT_LANGUAGE, "en-CA,en-US;q=0.7,en;q=0.3");
headers.set(HttpHeaders.HOST, "www.homedepot.ca");
headers.setAccept(Arrays.asList(MediaType.ALL));
HttpEntity<Map<String, String>> entity = new HttpEntity<>(headers);
response =
restTemplate.exchange(prodApiurl, HttpMethod.GET, entity, HDCanadaRecomProdResp.class);
}而现在错误已经更改为
org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://www.homedepot.ca/api/rec/v1/recommendations/fbt/products/1001200972/store/7301":

对于这类云运行相关问题，请使用绞合。还可以在GCP控制台的Cloud部分(而不是在Cloud部分的“logs”选项卡中)查看日志，您可以在varlog/系统日志中查找具有“调试”严重性的"Container“。还尝试使用这些使用说明在Docker上本地运行应用程序，并验证应用程序在本地引导是否良好。容器必须侦听发送请求的端口上的0.0.0.0上的请求。默认情况下，请求发送到8080。在cloudbuild.yaml文件中添加--min-实例，并给它提供一些值，然后尝试。
如果您看到这个日志(在前面看不到，因为它是在容器启动期间出现的) Debug 2021-11-07T12:39:14.876726806ZContainer Sandbox: Unsupported syscall setsockopt(0xa,0x11,0x67,0x3ed0ac62bffc,0x4,0x1a)并且您能够在本地运行安装程序，这意味着对接映像或您的配置没有问题。Unsupported syscall- --这条消息表明，在云运行中可能不支持系统调用(完全托管)，因为容器实例是使用gVisor容器运行时沙箱进行沙箱封装的。
详见socket(7) - Linux手册第8页。所以gvisor不支持这个套接字选项。看看这个Github问题，它讨论的是您收到的相同的错误消息。
这是云运行完全管理中的一个已知问题。您可以使用相同的配置和容器设置(分配的资源较少)尝试云为Anthos跑。
