TKGS Tanzu px-bench configuration recommendations

Overview

These are recommendations for deploying and testing with px-bench in a TKGS Tanzu cluster that supplement px-bench main README.md

Cluster environment prep

Create namespaces and rolebindings [if needed] for chewram and px-bench

kubectl create ns chewram
kubectl create rolebinding rolebinding-default-privileged-sa-ns_default --namespace=chewram --clusterrole=psp:vmware-system-privileged --group=system:serviceaccounts

kubectl create ns px-bench
kubectl create rolebinding rolebinding-default-privileged-sa-ns_default --namespace=px-bench --clusterrole=psp:vmware-system-privileged --group=system:serviceaccounts

Modify px-bench environment settings for the deployed storageclasses and newly created namespaces

Create a working version of a copy of the examples/generic/px-bench-env.yml file and customize it:

• metadata.namespace: px-bench add to: ServiceAccount, ConfigMap, Role, RoleBinding, Job
• storageclass_list: [quoted space-separated list of storageclasses to be used by benchmarks; e.g., "sc-01 sc-02"]

Customize px-bench-main.yml file:

• metadata.namespace: px-bench add to: ConfigMap, Role, RoleBinding, Job
• set runAsNonRoot: false for both fio and run containers:
  fio container: ConfigMap "files", run.sh, Job "fio", spec.template.spec.containers.securityContext
run container: Job "run", spec.template.spec.containers.securityContext

As described in px-bench main README.md, apply chewram,yml, px-bench-env.yml, px-bench-main.yml and continue with post benchmarking monitoring and retrieval operations.
