Heketi manages storage on Gluster servers and exposes high level RESTful APIs for consumers to dynamically provision storage from multiple Gluster trusted storage pools. So far it works with a few changes for standard token and api locations but doesn't persist the database or load the topology automatically. With Heketi, cloud services like OpenStack Manila, Kubernetes, and OpenShift can dynamically provision GlusterFS volumes with any of the supported durability types. Integration with K8s RBAC, Active Directory and LDAP, CIS hardening by default, encryption at rest and automatic security patching ensure you get the most secure Kbernetes in the market. @hunter How about also introducing an endpoint as a part of helm chart?

The ibm-glusterfs Helm chart deploys a GlusterFS storage cluster on the storage nodes in your IBM® Cloud Private cluster. 创建 pvc 后,Kubernetes 会调用 heketi 的 create volume API。之后 heketi 将会去检查 glusterfs 集群的可用空间。本文指定了 rep3 的 storageclass, 所以需要 3 个节点有至少 10G 的可用磁盘空间。如果满足条件,Kubernetes 则会创建相应大小的 PV (Persistent Volume),并绑定该 PVC。 However if the namespace gets removed, these are removed too irrespective of the annotation value. Familiarity with volumes and persistent volumes is suggested. Im Rahmen dieser Schulung erfahren Sie alles wichtige, um Kubernetes effektiv für Ihre Applikationen einsetzen zu können. Kubernetes (k8s) is an open-source system for automating deployment, scaling, and management of containerized applications. I thought I'd raise a ticket early for tracking and inputs but the addition of etcd and daemonset features to Heketi should let us wrap this up and push it upstream. Heketi also supports any number of GlusterFS clusters, allowing cloud services to provide network file storage without being limited to a single GlusterFS cluster. Since I’m running bare-metal cluster it has no proper storage solution. User account menu. I've not had time to implement but both of those could be handled by init-containers which would also remove the need for a deploy-heketi resource.
