如何检测Docker容器是否崩溃

我每5分钟运行一次进程并检查以确保每个容器。如果容器不响应，我可以将其标记为下降。我有容器IP地址，然后循环浏览每个IP，并检查它是否响应Ping。如果没有，我将其标记为下降。有一个更好的方法吗？我的代码：

1. @Transactional
2. @Scheduled(fixedRate = 1000 * 60) //5 min
3. public void monitorHosts(){
4. Iterable<Ncl> ncls = nclRepository.findAll();
6. for(Ncl ncl: ncls){
7. for(String host: ncl.getHosts()){
8. Boolean isHostAlive = isHostAlive(host);
9. if(!isHostAlive){
10. Ncl nclWorking = nclRepository.findOne(ncl.getUuid());
11. if(nclWorking != null){
12. Set<String> hosts = nclWorking.getHosts().stream().filter(x -> x.equals(host)).collect(Collectors.toSet());
13. nclWorking.getHosts().clear();
14. nclWorking = nclRepository.save(nclWorking);
15. nclWorking.setHosts(hosts);
16. nclRepository.save(nclWorking);
17. }
18. }
19. }
20. }
21. }
23. private Boolean isHostAlive(String host){
24. try{
25. InetAddress address = InetAddress.getByName(host);
26. boolean reachable = address.isReachable(10000);
27. return reachable;
28. } catch (Exception e){
29. e.printStackTrace();
30. return false;
31. }
32. }
