There is no public Docker image release available.\n\nThis projects allows the creation of PersistentVolumeClaim (PVC) for local volumes.\nA PersistentVolume (PV) corresponding to this PVC will dynamically be created.\nA filesystem volume will dynamically be created and mounted on the host where the pod is scheduled.\n\n## Components\n\nThis project is composed of 3 main components:\n\n* The provisioner: watches new PVC resources and creates matching PV resources on the apiserver. Cluster-wide deployment of a single pod.\n* The driver client: binary deployed on k8s nodes that respects k8s flex interface. Called by kubelet when a scheduled pod needs a local persistent volume to be mounted. Contacts the driver daemon through a unix socket.\n* The driver daemon: daemonset with one pod per k8s node. Listens to calls from the client. Creates a logical volume for the pod on the underlying host (eg. /mnt/storage/my-pvc), and bind mount it within the pod directory on the underlying host (eg. /var/lib/kubelet/pods/pod-id/volumes/elastic-local/my-pvc).\n\n## Development\n\nTo start, get a working development Kubernetes cluster using [Minikube](https://kubernetes.io/docs/tasks/tools/install-minikube/#install-minikube) or [GKE](https://cloud.google.com/kubernetes-engine/):\n\n```bash\nmake -C ../operators bootstrap-minikube\n# or\nGCLOUD_PROJECT=my-project-id make -C ../operators bootstrap-gke\n```\n\nIf you chose Minikube then attach a new disk to the virtual machine:\n\n```bash\nmake minikube-attach-disk\n```\n\nFinally initialize a logical volume group:\n\n```bash\nmake minikube-create-vg # or gke-create-vg\n```\n\n## Usage\n\nBuild and push the Docker image:\n\n```bash\nmake docker-build-push\n```\n\nDeploy on Kubernetes:\n\n```bash\nmake deploy\n```\n\nThen you can create any PVC matching the `elastic-local` storage class and Pod using this PVC. Example:\n\n```bash\nkubectl apply -f config/pvc-sample.yaml -f config/pod-sample.yaml\n```\n\n## Architecture\n\n![architecture](https://github.com/elastic/cloud-on-k8s/blob/master/local-volume/architecture.svg)\n\nThe provisioner only interacts with the APIServer: it watches any new PVC matching our StorageClass provisioner, and dynamically creates a matching PV.\n\nWhen the pod gets scheduled on a host, the kubelet calls our driver binary in order to mount a volume in the given pod directory. In turn, our driver binary calls our driver daemon (HTTP through a unix domain socket). The driver daemons is responsible for creating the volume, creating an actual directory mount for it on the file system, then bind-mounting this directory into the given pod directory.\n\n## Limitations\n\n* Thinly provisioned volumes are not supported on GKE\n* We don't handle total storage capacity requirements.\n\n## Flex spec\n\nWe are doing implementation option 1 from the spec below :)\n\n```\n----------- Mandatory ------------\n init // Performs driver initialisation\n----------- Implementation option 1 -----------\n attach // Attaching persistent volume to the host\n waitforattach // Waiting for volume to be attached (10 minutes timeout)\n isattached // Check if the volume is attached\n detach // Detaching persistent volume from the host\n mountdevice // Mount the device to a global path so the pod can bind to it by Kubelet\n unmountdevice // Un-mount the device from global path\n----------- Implementation option 2-----------\n mount // This call-out implements both attach and mountdevice functions\n unmount // This call-out implements both unmountdevice and detach functions\n```\n","has_starred","hub_user","immutable_tags_settings",{"_71":11,"_72":73},"enabled","rules",[74],".*","is_automated","permissions",{"_78":17,"_79":11,"_80":11},"read","write","admin","user","storage_size",222130065,"orgData","recentTags",[87,125],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":96,"_46":114,"_115":90,"_116":29,"_117":52,"_53":118,"_119":120,"_121":105,"_122":114,"_123":61,"_124":17},"content_type","creator",14777,"full_size",148809012,"id",60634039,"images",[97],{"_98":99,"_100":101,"_102":103,"_104":105,"_106":107,"_108":109,"_110":103,"_111":-5,"_112":92,"_59":61,"_113":-5},"architecture","amd64","digest","sha256:dc03adb718f7814764f7b48d8844784d4c3006b9fffc1b04be7cc69ccfed3fca","features","","last_pulled","2026-09-27T00:33:17.556395847Z","last_pushed","2019-07-01T19:36:08Z","os","linux","os_features","os_version","size","variant","2019-07-01T19:36:07.687805Z","last_updater","last_updater_username","media_type","latest","repository",7343929,"tag_last_pulled","tag_last_pushed","tag_status","v2",{"_88":40,"_89":90,"_91":126,"_93":127,"_95":128,"_46":133,"_115":90,"_116":29,"_117":52,"_53":134,"_119":120,"_121":131,"_122":133,"_123":61,"_124":17},148716448,60630894,[129],{"_98":99,"_100":130,"_102":103,"_104":131,"_106":132,"_108":109,"_110":103,"_111":-5,"_112":126,"_59":61,"_113":-5},"sha256:65676f47883edb1aca55d48bebc635f6a6472f13a004f7da6eb7dde722ef744a","2026-09-27T00:31:05.166484469Z","2019-07-01T19:04:46Z","2019-07-01T19:04:45.992883Z","0.8.1","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","showSbxLogoOverride","sbxTrademarkText","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"routes/_layout.r.$namespace.$reponame.tags",{"_34":146,"_153":154,"_142":167,"_168":11},{"_36":147,"_38":148,"_41":42,"_43":44,"_45":11,"_46":47,"_48":49,"_50":149,"_53":31,"_28":29,"_54":55,"_56":40,"_57":58,"_59":58,"_60":61,"_62":-5,"_63":64,"_65":66,"_67":11,"_68":29,"_69":150,"_75":11,"_76":152,"_81":29,"_82":83},[],[40],[52],{"_71":11,"_72":151},[74],{"_78":17,"_79":11,"_80":11},"tags",{"_155":156,"_157":-5,"_158":-5,"_159":160},"count",2,"next","previous","results",[161,164],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":162,"_46":114,"_115":90,"_116":29,"_117":52,"_53":118,"_119":120,"_121":105,"_122":114,"_123":61,"_124":17},[163],{"_98":99,"_100":101,"_102":103,"_104":105,"_106":107,"_108":109,"_110":103,"_111":-5,"_112":92,"_59":61,"_113":-5},{"_88":40,"_89":90,"_91":126,"_93":127,"_95":165,"_46":133,"_115":90,"_116":29,"_117":52,"_53":134,"_119":120,"_121":131,"_122":133,"_123":61,"_124":17},[166],{"_98":99,"_100":130,"_102":103,"_104":131,"_106":132,"_108":109,"_110":103,"_111":-5,"_112":126,"_59":61,"_113":-5},[],"canDeleteTags","actionData","errors"]
