AKS seems to ignore Kubernetes load balancer annotations

Asked 2022-Mar-22 at 12:45

I need to switch off some probes on LB for LoadBalancer type services. As this is not possible I fall back to trying to set long probe interval. This can be done by annotations defined on this documentation page.

But I am not able to update the health probe values, the annotations are not working. I verified that it works for setting internal LB, but I am not able to influence the probes by annotation. Is there any other requirement other then having kubernetes version higher than 1.21?

UPDATE

Answered 2022-Mar-22 at 12:45

The reason for the annotations not being picked up is describe here. Either you need to enable Cloud controller or rise version of AKS to 1.22

QUESTION

AKS: connect to external service on a different aks cluster on private network

Asked 2022-Feb-03 at 08:29

my goal is to call a service on an aks cluster (aks1) from a pod or a service on a second aks cluster (aks2). These clusters will be on different regions and should communicate over a private network.

Azure CNI plugin.

So, after some reading and some video listening, it seemed for me that the best option was to use an externalName service on AKS2 calling a service defined in a custom private DNS zone (ecommerce.private.eu.dev), being these two VNets paired before.

...

ANSWER

Answered 2022-Feb-01 at 10:36

In AKS the service CIDR is not part of your vnet address space and therefore it is not routed by Azure in any way so you won't be able to connect from a pod directly to a service in another cluster.

What you have to do is:

Expose your service using i.e. an ingress (which i think you are trying to do but the commands show only generating a yaml for ingress rule not the actual creation of ingress rule)
A-record in your privat DNS zone should point to the private IP address of your load balancer not your service IP address

With this your high-level communication scheme would look like this: (aks1)pod -> (aks2)lb -> (aks2)ingress -> (aks2)service -> (aks2)pods

QUESTION

Python asyncio loop already running when using asyncio.run and trying to add tasks

Asked 2021-Dec-23 at 16:52

I am very new to asyncio and I find the EchoServer example very confusing. I am trying to achieve a simple situation where a server accepts multiple clients, runs that in a coroutine and handles data, and a UI thread which handles ncurses input. I currently have the following, which, in code, conveys the idea I think. But it does not work.

How do I fixed skipped input/output lines in Java Echo Server?

Asked 2021-Nov-26 at 19:36

New to network computing, so forgive my ignorance:

All of my commands work except for the /caesarcipher - when I enter it, I don't receive an echo until the next message on the client side, and the server doesn't begin to perform the function until 2 subsequent messages have been sent.

Any help would be appreciated!

To be frankly, there are too much to read through, it would be better if you described some part of your codes more specifically, and there would be more people be willing to help you. Nonetheless, here are some suggestions for your codes, hope this helps.

You need to remove /home/quan/ns-allinone-3.29/ns-3.29/build/ns3 from the include paths. Looking at the example codes, it always gets ncs in the path and you don't need it to be added in include_directories. The string.h from ns3 conflicts with one defined in STL

If you want to use kubernetes inside a docker container my suggestion is to use k3d .

k3d is a lightweight wrapper to run k3s (Rancher Lab’s minimal Kubernetes distribution) in docker.k3d makes it very easy to create single- and multi-node k3s clusters in docker, e.g. for local development on Kubernetes.

You can Download , install and use it directly with Docker. For more information you can follow the official documentation from https://k3d.io/ .

To get the list of pods you dont' need to create a k8s cluster inside a docker container . what you need is a config file for any k8s cluster . ├── Dockerfile ├-- config └── main.py 0 directories, 3 files

Along with the other EchoServerHandler, I have two ChannelHandler now, I'd like to print a message from each ChannelHandler, and write back a message to Client from each ChannelHandler.

EchoServerHandler will also write msg. This will cause msg be released twice in ChannelOutboundBuffer.

You can remove EchoServerHandler or call in.retain() before write in your AnotherEchoServerHandler

TL;DR

There are some ways to fix your Ingress so that it would get the IP address.

You can either:

Delete the kubernetes.io/ingress.class: nginx and add ingressClassName: public under spec section.
Use the newer example (apiVersion) from official documentation that by default will have assigned an IngressClass:
- Kubernetes.io: Docs: Concepts: Services networking: Ingress
