Deploy ECK on OpenShift

editThis page shows how to run ECK on OpenShift.
Some Docker images are incompatible with the restricted
SCC. This is the case for the APM Server before 7.9 and for Enterprise Search 7.9 and 7.10. You can use this workaround to run those images with the anyuid
SCC.
Before you begin

To run the instructions on this page, you must be a
system:admin
user 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_count
sysctl setting applied. By default, Pods created by ECK are likely to run with therestricted
Security 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: false
at the Elasticsearch node configuration level. This has performance implications and is not recommended for production workloads.For more information, check Virtual memory.
