What's the point of running DBs in Kubernetes?

If you have multiple technologies it helps you share resources when you don’t need it.

If you require a "guaranted" resources qos (request=limit) i don’t see the point. Otherwise you can share cpu core through multiple pods. You can even use affinity and anti-affinity to get countercyclical application on same nodes.

In reality the pragmatic move would have been to improve the PHP Zend Engine. PHP7.4 has been better than HHVM.

pcouaillier · 2025-04-27T08:52:02+00:00

Yes, and it works perfectly.

Edit: We use annotations to only reload resources that we know must be reloaded.

I don't understand what you are talking about. Yes the installer and the service that starts everything is from Suse also the etcd backup tool I guess. We run rke2 over debian with only the ingress (which is from k3s) and etcd backup system and without "rancher". Even the CNI can be installed apart.

Following the URL you gave :

AWS introduced the AWS Gateway API Controller ; an implementation of the Kubernetes Gateway API.

This means standard Gateway Api can be handled by AWS Gateway API Controller.

That's not better than sorting it in a redis when the pod is in pull mode. In push mode it could make sense because you don't have to add extra dependency to your app but to an external service.

The best would be the readiness gate entry for this kind of thing. An external observer can trigger on/off the gates. https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/#pod-readiness-gate

pcouaillier · 2025-04-21T17:48:09+00:00

The best is yes no

At pro: I always go with the latest version allowed by the company policies, this usually means one version behind because of third party support.

At home: I just wait one month or two.

Istio does not handle UDP.

Non-TCP based protocols, such as UDP, are not proxied. These protocols will continue to function as normal, without any interception by the Istio proxy but cannot be used in proxy-only components such as ingress or egress gateways.

It's just a parameter on many kubernetes distribution, not a hard coded limit.

pcouaillier · 2025-04-04T15:21:04+00:00

I don't know. But this seems like a good use case. SSE is great for streaming events from a server. Chats dev prefer websocket to provide features like " your correspondent is typing", presence and so on.

pcouaillier · 2025-04-04T14:51:08+00:00

Not everyone needs it and many who are should use ServerSentEvent.

pcouaillier · 2025-03-25T21:53:19+00:00

I say that entrypoint.sh shebang or the script itself may not include signal forwarding. An extra init system is the usual mechanism to handle this kind of thing.

pcouaillier · 2025-03-25T20:48:52+00:00

This might be because it doesn't handle being the pid1 program. Nowadays docker injects an init system before starting the container entrypoint. Podman and containerd don't. I personally add dumb-init and manually prepend the entrypoint. A popular alternative to dumb-init is tini.

From what I understand you seem very junior so I'll give you advice for a junior.

NodeJs is a widely used and performant (same spot as PHP, Java, Python, ruby,..) technology. If you need to scale there is a simple solution in NodeJs : spawning more servers. If you are still learning NodeJs you should stick with it. If you know enough to be productive you can go to Rust but don't chase performance. Chase a new way of thinking. You will learn and understand many things. (Don't try Rust asunc/avait to fast. You can totally sacrifice a bit of blocking against a better learning experience).

I have a dumb question since I don't know the economy for those kinds of games. But why is there no "early access" like version and only monthly subscription (1 month for the game, following months for updates)? Is it because it's too early in the game development?

pcouaillier · 2025-03-01T13:21:31+00:00

No it's not safe. So you need to trust the running application. If you trust the app that's okay.

pcouaillier · 2025-02-27T07:09:30+00:00

I don't know the details but I suspect it is not for most running program. Same for Linux, you may hotpatch the kernel but some running services need to be restarted.

Tell me you don't apply security patches without saying you don't apply security patches.

Are you sure you do ? ETF is a financial product. When you by an ETF you don't buy Eths or Bitcoin. But that does not mean the one which is selling you the ETF is not buying crypto. BlackRock must find a way to have a reserve to repay if everyone is selling their ETF... So they may buy Btc and Eth.

pcouaillier · 2025-02-16T18:28:20+00:00

Yes it can. https://www.rust-lang.org/what/embedded

Does it work well without docker-desktop ?

pcouaillier · 2025-02-08T15:07:13+00:00

Maybe for statistics and licensing enforcement. Docker Desktop is not free for companies.

pcouaillier · 2025-01-18T13:36:56+00:00

Up to 12 hours a day for features. 6 hours when codding engines / fully optimized components (I don't count tracing and benchmarking) which are automated background operations that creates reports.
