In rare scenarios ConfigMap update is not updated using polling strategy #1592

gmrammohan15 · 2024-03-04T05:44:54Z

Describe the bug
Intermittently once pod is deployed,
Any configMap resource update is not getting applied to the Application
We see in problematic pods, we continously see below WARN messages
10:12:24.807 WARN --- [TaskScheduler-1] o.s.c.k.c.c.reload.ConfigReloadUtil : The current number of ConfigMap PropertySources does not match the ones loaded from Kubernetes - No reload will take place

This does not happen normally, but happens sometimes after which its not recoverable, we need to go for full deployment to overcome.No new configMap updates will be applied.

We see that ConfigMap resource is updated in K8s. we could verify using kubectl describe cm
But K8s spring cloud is not able to accept or update the newly updated resource.

wind57 · 2024-03-04T09:39:34Z

Something is very off here, tbh. The thing that bothers me the most from glancing over the logs is this:

[Fabric8ConfigMapPropertySource@232678616 {name='configmap..wxc-dhruva', properties={}}]

This name: configmap..wxc-dhruva is kind of impossible :| We compute the name of a source from <type_of_source> (configmap/secrets) + <namespace_you_provided> + <name_of_the_source>, so this one should really be:

configmap.dhruva-proxy-static-config-map.wxc-dhruva or configmap.dhruva-proxy-dynamic-config-map.wxc-dhruva.

It has been a while since I've looked at that code, but I will look a bit more and try to figure out what is going on.

The second issue that bothers me too, is those logs left size: 1 and right size: 2, which implies something wrong again...

I will try to refresh my memory about things and will get back as soon as I have any hints of what is going on.

wind57 · 2024-03-04T10:38:27Z

Is there a way you can provide debug logs from the entire org.springframework.cloud.kubernetes package, btw?

gmrammohan15 · 2024-03-05T01:40:42Z

We had to restart the pod to get things working again, hence lost the logs.We have enabled debug logs in integration environment, will post if the issue gets reproduced again.

gmrammohan15 · 2024-03-05T01:45:19Z

Just thinking , since most of the times it works fine, is there any corner scenario (e.g temp network issue or something like that) that gets into this state. Like when this happens, it never comes out of this state ("does not match the ones loaded from Kubernetes").However the new pods or other pods in the same cluster talking to the same API server works fine.
Not sure when it gets in to this state if it always returns back from cache for every polling interval since actual call should have returned correct data. By default what is the cache expiry time.

wind57 · 2024-03-05T20:36:03Z

We do have a cache in place, but it works differently, it is request based, not time based. But it's irrelevant for now, I will leave it aside for the time being.

What I can't get my head around is how this property source : configmap..wxc-dhruva came to life. The thing that I don't understand is that our code does something like this:

 1) what do I currently have in my environment?
 2) let me re-compute property sources based on your provided input
 3) compare (1) to (2)

The weird part is that the answer to (1) (right size: 2) seems to be (from your trunked logs):

configmap.dhruva-proxy-static-config-map.wxc-dhruva
configmap.dhruva-proxy-dynamic-config-map.wxc-dhruva

Which means that we did manage to read correctly at the bootstrap time (your "app config" is really a bootstrap.yaml looks like), the properties which you have defined via JAVA_OPTS.

In other words you told us the namespace you use: wxc-dhruva, the two config maps we are supposed to read from : dhruva-proxy-static-config-map and dhruva-proxy-dynamic-config-map and we did that; that right size: 2 and those two BootstrapPropertySources, is proof that it worked.

When pooling happens, we go to environment, see that we have already those two loaded, and try to compute them again, from the same properties that you provided initially. At this point, from your logs, I see a property source with name configmap..wxc-dhruva which makes no sense at all. The name of the configmap is missing entirely, so I have no idea how we got to this point, honestly.

The debug logs I hope that you will provide, will bring me a bit closer to solving this puzzle.

gmrammohan15 · 2024-03-06T23:29:37Z

Sure, will update once the issue is reproduced with logs.Will monitor and provide more details.

ryanjbaxter · 2024-10-17T13:01:27Z

Are these the debug logs that @wind57 requested as well?

gmrammohan15 · 2024-10-18T11:58:09Z

yes, correct.

wind57 · 2024-10-21T08:16:30Z

as usual, time is the limiting factor for me... I will be looking at this one, but no timeline when exactly.

wind57 · 2024-10-22T14:02:21Z

The error happens in the KubernetesClient itself that we are using (fabric8) and it fails within its http library that it uses: okhttp3. There was a timeout when we tried to get the configmaps using that client, and it seems that the connection is canceled at that point in time. It goes something like this:

give me the configmaps
for that, fabric8 issues a http request (using okhttp3) to the k8s api server
there was a timeout that happened when waiting for the response from above
the library kills the request and throws a timeout exception

At least this is my understanding of the stacktrace above. The thing is, all of this happens outside our code in spring...

But either way, these are not full debug logs, I was expecting a lot more output and some debug statements that are not provided. The are many other log statements that we have in our code base that you have not provided, without them I can't help you

gmrammohan15 · 2024-10-22T14:55:35Z

@wind57

Thanks for looking into it.Below are the logs that we could capture apart from the stack trace.
Have highlighted certain section of logs.After the operation exception happens , it detects a change which is strange and should not happen.Post that subsequent polling always has left size and right size mismatch ( due to entry ..) and any change is configMap does not trigger refresh.

Note: Have masked some actual content of configMap due to security reasons.

hoooly moly! @ryanjbaxter this is a bug, please re-open this one if there is such an option and add the bug label. Thank you.

These logs have been invaluable, without them diagnosing this issue would have been impossible.

I'll try to summarize what happens:

user has configured two configmaps for property sources in namespace a, let's call them one and two
When the app starts they are both read just fine and properties are populated correctly.
At the same time, we create two property sources in Springs environment: configmap.one.a and configmap.two.a
user enabled polling reload, so we will be polling k8s on a periodic bases to see if there are changes
at some point in time, one of the calls to k8s fails (like user reported above), but we do not fail, instead, we log and move on:

In NamedSourceData (failsFast is false)

catch (Exception e) {
      onException(failFast, e);
}

We then try to find the names of the sources we read previously. Since we never failed above and only logged the issue, there will be no such names. We kind of do something like this:

	public static void main(String[] args) {

		new NamedSourceData() {
			@Override
			public MultipleSourcesContainer dataSupplier(LinkedHashSet<String> sourceNames) {
				return null;
			}
		}.go();

	}

	void go() {
		
		MultipleSourcesContainer data = MultipleSourcesContainer.empty();
		String names = data.names().stream().sorted()
			.collect(Collectors.joining(PROPERTY_SOURCE_NAME_SEPARATOR));
		SourceData sourceData = new SourceData(generateSourceName("configmap", names, "namespace", new String[]{}), data.data());

		System.out.println(sourceData);

	}

And the above prints: SourceData[sourceName=configmap..namespace, sourceData={}]

And this is exactly what the OP sees:

configmap..wxc-dhruva

This was the first mystery that was solved today.

But the above does not cause the issue, the real problem is that we will register this property source in Spring environment, though, so at the end of this operation there are 3 property sources:

configmap.one.a
configmap.two.a
configmap..a

while in k8s there are only first two... SO every next cycle of polling will fail, since the size of them are different, all the time. There is no way to recover from this.

I will think how to properly fix this in the upcoming days and present a PR.

@wind57 Really glad to know this.Had seen the logException code which just logs and moves on, but wasn't clear why empty source data remains persistent in all the future checks.Now based on your explanation its clear.Thanks much.
Looking forward for your fix.

wind57 · 2024-11-05T12:15:32Z

unfortunately, I'm at square zero here, after looking and the code and logs far closer, my explanation above only makes partial sense and the logs tend do disagree with my analysis. I will take a fresh look over them in a few days, may be something pops up.

gmrammohan15 · 2024-11-05T12:48:35Z

Sure @wind57 . Just curious , which part of code and log is not aligning with analysis.

wind57 · 2024-11-06T19:21:35Z

finally I had some time to put up a test to reproduce this issue, sorry it takes so much and I am so slow at this, this unfortunately is not my main job and I have little time these days...

Anyway, I did reproduce it via a test. It is indeed a bug on our side, I am positive about this. The core issue is still in the fact that when there is an error, we generate an incorrect name. The thing you need to get an error twice and some very unlucky timings.

I am not going to bother you with details, I need to think on how to solve this one now. :)

gmrammohan15 · 2024-11-07T00:48:34Z

np, i understand. Really thanks for taking time for looking into this.Its a complex one , based on the symptoms i did try introducing few error scenarios to reproduce locally but couldn't.

wind57 · 2024-11-08T17:44:07Z

I have a PR in motion to fix this, but I found a few improvements that we should make while investigating. As soon as those are reviewed and approved, I'll create the fix.

For the history, here is what happens.

In your current environment you have two property sources:

configmap.wxc-dhruva-proxy-dynamic-config-map.wxc-dhruva-mno

configmap.wxc-dhruva-proxy-static-config-map.wxc-dhruva-mno

At some point, polling reload kicks in and we go to the k8s to see if there are any changes. While trying to read configmaps, we fail (that is the error you see with OK http3 that I explained). At that point we generate and incorrect name for a property source:

configmap..wxc-dhruva-mno

But, this one fails while reading the first configmap, it passes for the second one. So we end up with two property sources in environment and two coming from k8s, then we try to compare them and of course they differ (we compare contents not names). So... we say - "refresh".

Well, now when you call refresh, you reload property sources and fail again (you can see that "Operation: [list] for kind: [ConfigMap] with name: [null] in namespace: [wxc-dhruva-mno] failed.. Ignoring" twice), thus we generate in incorrect source name again. The difference now, is that unlike previously, this source is put into your Spring environment. So you end up with 3 sources that Spring knows about:

configmap.wxc-dhruva-proxy-dynamic-config-map.wxc-dhruva-mno

configmap.wxc-dhruva-proxy-static-config-map.wxc-dhruva-mno

configmap..wxc-dhruva-mno

Every next cycle compares these 3 to the 2 from the cluster and will always fail.
