I have an issue with my Qovery configuration. On my project, for the prod environment, I have several apps that I need to deploy. The problem I have is that the deployment of those apps is distributed over multiple different instances, which means that I have much more running EC2 instances than I…

Hi, It’s not planned since it’s not a good practice. Why? Because you can easily overcommit and impact other applications running on the same nodes than yours. It can be too problematic (you can find several articles on the topic ), however for applications/containers deployed with Qovery. However,…

Hello @Talal This kind of configuration is not available as we don’t recommend this setup as nodes can crash and then your applications will not be available if all the pods run on this node. The only configuration available is the deployment.antiaffinity.pod . Could you please provide the URL of …

Thanks for the answer @Pierre_Gerbelot . I’m not sure I understand the problem of this configuration. There are always multiple nodes running (at least 3 in the configuration I’m thinking of), so if one crashes with all the pods, the other ones will continue working until a new node is created, no? …

When checking your nodes resource consumption, I can see that you have requested much more CPU than you actually use. None of your nodes has less that 60% of requested CPU so the cluster autoscaler can’t drop any node. But indeed the utilization is very low. I encourage you to review the resources…

Thanks @Pierre_Gerbelot . I have some questions though. Just to be sure, can you confirm that: Allocatable is the maximum number of CPU that can be used on the node Requested is the sum of all the CPU requested by all the apps that are installed on the node Utilization is the actual usage (at th…

Sorry to meddle in the conversation, but @Pierre_Gerbelot but that resource utilization/requested graph is very useful. What command did you use to get that info for our nodes?

The data have been dumped using the following tool , you can find all description of the column in the README. When Kubernetes starts a pod on a node, it allocates the requested resources for that pod. Regarding the cron job, pods are started only during the execution time, so the resources are onl…

Thanks @Pierre_Gerbelot . Would you know if there is a tool that tracks CPU usage of a container over time? My goal is to try to see and understand what’s the real CPU consumption of a container so that I can set its resources to a better value (rather than just doing it by trial and error). Thank…

@Pierre_Gerbelot I reviewed the setting for some of the apps, so it’s a bit better but still far from what I would expect. For example, right now, this is what I have: [Capture d’écran 2024-02-13 à 10.10.09] There are 4 nodes with a Requested CPU below 60% (and a very low usage), but no down s…

Hi @Talal , I think you might find this thread useful [image] How Kubernetes CPU and RAM resources allocation works with Qovery? Deployment Hey guys! Coming here for a bit of help on how to better think about configuring our infrastructure with Qovery. Basically we have…

Thanks @rophilogene . The thread is useful indeed. But it doesn’t answer this question: “When I allocate some resources to an app, let’s say 500mCPU. Does that mean that the app will use at the maximum 500mCPU, or can it use more if there is some available CPU in the node?”
