Question about running a Discord.NET bot in a k8s cluster using ASP.NET | Discord.Net | Page 1

Hi everyone,

I’m developing an ASP.NET application that includes endpoints for oAuth2 and a Discord.NET bot. The app be deployed in a k8s cluster with at least 4 pods, and this setup cannot be changed.

My question: how can I ensure the Discord.NET bot runs on only one pod, and if the container with the bot crashes or disconnects, the bot automatically starts on another pod?

Has anyone implemented a similar scenario using the leader election pattern or other approaches? What are the best practices for solving this?

Thanks in advance for any advice!

I have no advice for this but just here to say you should try asking in some place that specializes in kubernetes

Try to make your bot a separate project if you have different scaling needs then your api, k8s will restart your pod if it crashes. Trying to manage restarting the bot in an already running aplication defeats the purpose of having k8s manage the resources.

#

The oauth endpoint can be in a separate project, maybe you can explain why you need it in the same project and I could give advice how to make them separte and still be able to communicate

the problem is that the infrastructure where I want to deploy the bot has a strict limitation of at least 4 pods on PROD (2+2 in different sectors zones)

Maybe you could add an async message queue and communicate the restarting event from one instance to another

#

Like azure service bus or rabbitmq

#

First instance to consume the message will start the bot
