This page shows how to run ECK on OpenShift.
Before you beginedit
To run the instructions on this page, you must be a
system:adminuser or a user with the privileges to create Projects, CRDs, and RBAC resources at the cluster level.
Set virtual memory settings on the Kubernetes nodes.
Before deploying an Elasticsearch cluster with ECK, make sure that the Kubernetes nodes in your cluster have the correct
vm.max_map_countsysctl setting applied. By default, Pods created by ECK are likely to run with the
restrictedSecurity Context Constraint (SCC) which restricts privileged access required to change this setting in the underlying Kubernetes nodes.
Alternatively, you can opt for setting
node.store.allow_mmap: falseat the Elasticsearch node configuration level, but note that this has performance implications and is not recommended for production workloads.
