tcp-services configMap add one configuration ， Other services that are accessed through tcp cannot be accessed properly #9943

wcsceshi · 2023-05-10T09:43:23Z

kubectl version 1.23.6, nginx-ingress-controller image version v1.3.0

What happened:
I added a piece of data to the tcp-services configMap，The ipv6 dual-stack nginx service is enabled，then ran the curl nodeIp:port command to get the normal service return data.
However, when I added another piece of data to the configMap of tcp-services（ipv6 dual stack is also enabled for nginx services）, I looped through shell.sh to access the previously added services and got an abnormal return，It took about 30 seconds to get the normal service result.

What you expected to happen:
When I add configuration data to the configMap of tcp-services, I do not affect access to other services that are also configured through the configMap of tcp-services

I created the service and pod through yaml
apiVersion: v1
kind: Pod
metadata:
name: nginx-2
labels:
app.kubernetes.io/name: proxy-2
spec:
containers:

name: nginx
image: nginx:stable
ports:
- containerPort: 80
  name: http-web-svc

apiVersion: v1
kind: Service
metadata:
name: nginx-service-2
spec:
ipFamilies:

IPv6
IPv4
ipFamilyPolicy: PreferDualStack
selector:
app.kubernetes.io/name: proxy-2
ports:
name: name-of-service-port
protocol: TCP
port: 80
targetPort: http-web-svc

configured the host port and service map in the configMap of tcp-services. I accessed the host and host port through curl command and got the correct response

curl nodeIp:31626

Then I create a service and pod with yaml
apiVersion: v1
kind: Pod
metadata:
name: nginx-3
labels:
app.kubernetes.io/name: proxy-3
spec:
containers:

name: nginx
image: nginx:stable
ports:

  name: http-web-svc

apiVersion: v1
kind: Service
metadata:

spec:
ipFamilies:

IPv4
ipFamilyPolicy: PreferDualStack
selector:
app.kubernetes.io/name: proxy-3
ports:
name: name-of-service-port
protocol: TCP
port: 80
targetPort: http-web-svc

Using a shell script, I use the for loop to curl the service I configured in tcp-services' configMap.
#!/bin/bash
for I in {1..50}; do
curl -v http://nodeIp:31626
let SUM=$I
echo "$SUM"
sleep 1
done
During shell script execution, the newly created service is also configured in the configMap of tcp-services. As a result, the curl command in the shell script returns some incorrect result. After a while, the curl command returns some normal result

Obtain correct results first, and then the result is not normal

and then get the right answer

longwuyuan · 2023-05-10T12:22:29Z

@wcsceshi I don't understand the problem you have described. Let us wait if someone else can understand and comment on this issue.

maybe you should not use nginx:stable image because nginx is commonly used for HTTP
maybe you can use mysql as one service to access over TCP
maybe you can use postgres as second service to access over TCP

wcsceshi · 2023-05-10T12:58:56Z

Sorry, maybe I didn't make myself clear.

What I mean by this is that if someone modifs tcp-services configMap, adds a configuration (e.g. 32100: default/app-svc:80) and saves it while I am accessing the service through tcp, I will only get an error result. like "connection reset by peer"。

I use tcp to access the IP address of the node where the ingress-controller pod resides and the port configured by the tcp -services configMap to access app service

longwuyuan · 2023-05-10T13:16:47Z

I still don't understand. I don't want to guess what problem you want the project to solve. So lets wait for some expert comments.

But if you referring to dropping established connections during config reload, then that is ow nginx works. The project maintainers are working on splitting control-plane and data-plane and that may improve the experience.

Good idea, i agree @longwuyuan

ghostloda · 2023-05-22T03:24:43Z

Hi,@wcsceshi @longwuyuan zoom chat

ghostloda · 2023-05-24T10:53:43Z

Steps to Reproduce the Issue:

Using tcp-controller-configmap for L4 Load Balancing
IPv6 Address endpoint
Delete one from tcp-controller-configmap

While deleting a service from the configmap, Lua will resynchronize the backend services. During this process, there may be an error the ipv6 address is not formatted, resulting in the unavailability of other services as well.

@longwuyuan @wcsceshi

ghostloda · 2023-05-24T12:13:55Z

The tcp-controller-configmap used for testing is as follows:

longwuyuan · 2023-05-24T17:34:36Z

@ghostloda why do you configure nginx webserver for TCP access ? Whole world uses nginx webserver for HTTP/HTTPS, not TCP.

ghostloda · 2023-05-25T01:44:35Z

@ghostloda why do you configure nginx webserver for TCP access ? Whole world uses nginx webserver for HTTP/HTTPS, not TCP.

Just as a backend service for testing.This is not the main focal point of the issue.

I think this issue is critical,when a TCP service(only ipv6) is deleting(or edit), it may affects the normal access of other services.We should promptly investigate and confirm this issue.

Based on the debug logs, the error is quite evident.

ghostloda · 2023-05-25T02:02:45Z

Hi,@longwuyuan I have already chat with @wcsceshi , and this bug was discovered in their production environment. This PR will fix the issue, and they have already tested it in their production environment.
Perhaps we should consider inviting more experienced contributors to help us verify this issue?

tao12345666333 · 2023-05-25T02:42:31Z

After a quick glance, I think reproducing this issue should be relatively simple.

@wcsceshi could you please format your examples? #9943 (comment)

The complete and directly usable reproduction steps will save everyone's time.

longwuyuan · 2023-05-25T03:02:54Z

@wcsceshi & @ghostloda , why don't you try mysql as one tcp service and postgresql as second tcp service. Then keep mysql and psql clients open for test.

Also, how about you disable ipv6 in the cluster.

Thirdly, any chance you can write more details about what is the app that you are using behind TCP ports.

Maybe we will discover more than just a unformatted ipv6 address.

Nginx reconciling during nginx.conf reload will cause some problems for sure. Maybe we will also find out why only you are reporting this problem and other users of TCP services are not reporting this problem.

I've seen others discover similar issues #9307

longwuyuan · 2023-05-25T05:13:11Z

That one also is using nginx webserver in example.
I think this issue should be titled specific to ipv6. I will test and update.

wcsceshi · 2023-06-01T06:22:29Z

I re-used two pod of mysql and the corresponding service with ipv6 enabled for testing. The testing procedure and test results are as follows

step1. i create two deployment and service （with ipv6）, the mirror is MySQL ， below is the resource object

[root@10 ingress-ipv6-svc]# kubectl get all |grep mysql
pod/ssx-mysql-dm-2-d8977d7cd-gs566        1/1     Running            0                 2m3s

service/ssx-mysql-sv-2    NodePort    2001:db8:40:1::ac8f   <none>        9001:31091/TCP   5h3m
deployment.apps/ssx-mysql-dm         1/1     1            1           4d23h
deployment.apps/ssx-mysql-dm-2       1/1     1            1           5h3m
replicaset.apps/ssx-mysql-dm-2-d8977d7cd        1         1         1       5h3m
replicaset.apps/ssx-mysql-dm-789c4dd484         1         1         1       4d23h

step2. add two pieces of data to the configMap of tcp-services

[root@10 ingress-ipv6-svc]# kubectl get cm -n ingress-nginx tcp-services -o yaml
apiVersion: v1
data:
  "9090": monitoring/prometheus-k8s:9090
  "32001": default/ssx-mysql-sv:9000

  creationTimestamp: "2023-03-08T10:01:30Z"

  selfLink: /api/v1/namespaces/ingress-nginx/configmaps/tcp-services
  uid: 106b64b3-f596-4e2c-8014-56c3ac43fa02
[root@10 ingress-ipv6-svc]#

step3. use IP of the node where the pod of nginx ingress controller is located，with the configured tcp host port，to access the created service . I was able to log into MySQL successfully and log out safely

[root@10 ingress-ipv6-svc]# mysql -h fd69:1:10:f980::a13:26e0 -P32001 -uroot -p1 sys
