COSBench Helm Chart

COSBench, is a benchmark tool for cloud object storage services. It is compatible with OpenStack Swift, Amazon S3, Scality Zenko, Ceph, CDMI, Google Cloud Storage, and other services.


This chart is deprecated and no longer supported.


$ helm install stable/cosbench


This chart bootstraps a COSBench deployment on a Kubernetes cluster using the Helm package manager.

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/cosbench

The command above deploys COSBench on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command above removes all the Kubernetes components associated with the chart and deletes the release.


The following table lists the configurable parameters of the COSBench chart and their default values.

Parameter Description Default
serviceAccounts.controller.create If true, create the controller service account true name of the controller service account to use or create {{ cosbench.controller.fullname }}
serviceAccounts.driver.create If true, create the driver service account true name of the driver service account to use or create {{ cosbench.driver.fullname }}
controller.image.repository controller image repository zenko/zenko-cosbench
controller.image.tag controller image tag 0.0.6
controller.image.pullPolicy controller image pullPolicy IfNotPresent
controller.service.type controller service type ClusterIP
controller.service.port controller service port 19088
controller.ingress.enabled If true, controller ingress will be created false
controller.ingress.annotations controller ingress annotations {}
controller.ingress.hosts controller ingress hostnames []
controller.ingress.tls controller ingress TLS configuration []
controller.logLevel controller log level DEBUG
driver.replicaCount number of driver replicas 3
driver.image.repository driver image repository zenko/zenko-cosbench
driver.image.tag driver image tag 0.0.6
driver.image.pullPolicy driver image pullPolicy IfNotPresent
driver.service.type driver service type ClusterIP
driver.service.port driver service port 18088
driver.logLevel driver log level DEBUG
driver.antiAffinity driver antiAffinity type soft
driver.hostAliases driver aliases for IPs in /etc/hosts []
driver.resources.requests driver resource requests Memory: 2Gi, CPU: 500m
driver.resources.limits driver resource limits Memory: 4Gi, CPU: 1

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install stable/cosbench --name my-release \
    --set driver.replicaCount=5

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

$ helm install stable/cosbench --name my-release -f values.yaml

Tip: You can use the default values.yaml
