QUESTION

2-Node Cluster, Master goes down, Worker fails

Asked 2022-Mar-28 at 15:13

We have a 2 node K3S cluster with one master and one worker node and would like "reasonable availability" in that, if one or the other nodes goes down the cluster still works i.e. ingress reaches the services and pods which we have replicated across both nodes. We have an external load balancer (F5) which does active health checks on each node and only sends traffic to up nodes.

Unfortunately, if the master goes down the worker will not serve any traffic (ingress).

This is strange because all the service pods (which ingress feeds) on the worker node are running.

We suspect the reason is that key services such as the traefik ingress controller and coredns are only running on the master.

Indeed when we simulated a master failure, restoring it from a backup, none of the pods on the worker could do any DNS resolution. Only a reboot of the worker solved this.

We've tried to increase the number of replicas of the traefik and coredns deployment which helps a bit BUT:

This gets lost on the next reboot
The worker still functions when the master is down but every 2nd ingress request fails
- It seems the worker still blindly (round-robin) sends traffic to a non-existant master

We would appreciate some advice and explanation:

Should not key services such as traefik and coredns be DaemonSets by default?
How can we change the service description (e.g. replica count) in a persistent way that does not get lost
How can we get intelligent traffic routing with ingress to only "up" nodes
Would it make sense to make this a 2-master cluster?

Running single node or two node masters in k8s cluster is not recommended and it doesnt tolerate failure of master components. Consider running 3 masters in your kubernetes cluster.

Kubernetes Traefik v2.3.0 - Web UI 404 Not Found after removing --api.insecure

Here's another take on the IngressRoute, adapted to your environment.

I think 99% of the issue is actual route matching, especially if you say --api.insecure works. Also as a rule of a thumb, logging & access log would help a lot in the DaemonSet definition.

How to use Traefik IngressRoute on a Headless Service

Asked 2020-Nov-30 at 15:13

I am trying to configure a Traefik IngressRoute to point to a Headless service (the service point to a Database behind the cluster). The Setup work well with a "normal" service (with the endpoint inside the cluster). I am using traefik 2.3.

But when I try to create an ingressRoute that point to the headless service, I have that error in the traefik logs:

ANSWER

Answered 2020-Nov-30 at 15:13

Resolved !

The error came from a misconfiguration of my service and endpoints.

The name I set for the port of my endpoints didn't match the name of the port of the service (in fact, I didn't set a name). Once the ports in the endpoints and the ports in the services have the same name set, everything worked fine.

QUESTION

Traefik Dashboard: Ingress and IngressRoute, can they co-exist?

Asked 2020-Nov-06 at 05:48

Recently I am moving a project to Kubernetes and have used Traefik as the ingress controller. For Traefik I have used the Traefik Kubernetes Ingress provider for routing. When I tried to add the Traefik dashboard, I found that seems it can only be added using IngressRoute (ie. using Kubernetes CRD as provider).

I have a few questions:

Is it possible to use Traefik Kubernetes Ingress provider to bring up the dashboard?
Can I use both kubernetesingress and kubernetescrd as provider? Can both Ingress and IngressRoute co-exist?

Answered 2020-Nov-06 at 05:48

Kusto/KQL: summarize by time bucket AND count(string) column

Asked 2020-Oct-01 at 17:43

I have a table of http responses including timestamp, service name and the http response code I want to query using KQL/Kusto.

My goal is to have a table that tells me "How many http responses of a certain type (2xx, 4xx etc) did a particular service have within the last 5 minutes over time"

I want to summarize the rows by a time bucket of 5min and the ResponseType (basically the response code class) as well - but I can't seem to make it work. When I add count(ResponseType) to the summarize clause, it returns the error message Function 'count' cannot be invoked in current context.
