#Ephemeral storage limit kubernetes update

Please update the issue description as suggested in the comment #361 (comment). Need to convert the design proposal into a KEP following the latest template to address all open checkboxes above and get it merged under the k/enhancements repo by 1.25 enhancements Freeze.įor note, the status of this enhancement is marked as at risk.Looks like for this one, we will need doing the following: KEP has a production readiness review that has been completed and merged into k/enhancements.KEP has a updated detailed test plan section filled out.If you specify an ephemeral storage limit, you can constrain the amount of ephemeral storage the container can use. The fastest way for developers to build, host and scale applications in the public cloud. KEP file using the latest template has been merged into the k/enhancements repo. Single-tenant, high-availability Kubernetes clusters in the public cloud.Here's where this enhancement currently stands: Just checking in as we approach enhancements freeze on 18:00 PST on Thursday June 16, 2022.įor note, This enhancement is targeting for stage stable for 1.25 (correct me, if otherwise) eg: set 20G quota for PODS that mean each pods can use only 20GB on ephemeral storage, if need more space should use the PV. It would be great if we restrict pods use a limited amount of ephemeral storage on cluster wide. Kubernetes clusters maintain hardware resources like CPU time, memory, ephemeral storage, and extended resources and assign them to running containers. This behavior is getting fill up the file system and stooping other pods to run. However, if you are on k8s 1. Requests and limits setting for ephemeral storage is a new feature and is still in beta.You might have to wait few more months to use that feature. īecause the pods run time writable layers or logs growing up and that will fill out /var/lib/docker filesystem. Then accordingly set those request and limits on that pod. I would like to check if there any way to restrict Pods usage on ephemeral storage /var/lib/docker) regardless of mounted on node root fs or separate file system of /var/lib/docker. Docker reports its root directory to the kubelet, so as long as your images are stored on the same partition that contains /var/lib/docker (or whatever your docker root dir is), this should work correctly. Make sure you have -root-dir set correctly. The behavior you describe should work regardless of this feature. We try the feature by this scenario, and found that it can not limit the capacity of container.
