Kubernetes supports two ways to configure local ephemeral storage on a node: Single filesystem Two filesystems In this configuration, you place all different kinds of ephemeral local data (emptyDir volumes, writeable layers, container images, logs) into one filesystem. It also allows OpenShift Container Platform to schedule pods where. Similarly: $ curl -k -H 'Authorization: Bearer ' \ This chapter covers storage options for Amazon EKS clusters. Configurations for local ephemeral storage. The ephemeral storage framework allows pods to specify their transient local storage needs. An example output: $ curl -k -H 'Authorization: Bearer ' \ vSphere with Tanzu uses storage policies to integrate with shared datastores available in your environment, including VMFS, NFS, vSAN, or vVols datastores. There are other tools that you can use to get metrics:ĬAdvisor also embedded into the kubelet code, exposed under the /stats/summary or /metrics endpoint. If you are not using volume mounts: $ du. Shell into your pod: $ kubectl exec -it shĬhange dirs to the mount point of your ephemeral-storage (if you are using volume mounts): $ mount # check mount points if you'd like emptyDir: empty at Pod startup,with storage coming locally from the kubelet base directory (usuallythe root disk) or RAM 2. Ephemeral storage is backed by boot disk size so increasing boot disk size will give you more. Also have a look at the graph in the following link. The pure raw approach for this is to use the disk usage (du) Unix command line. Kubernetes supports several different kinds of ephemeral volumes fordifferent purposes: 1.
