These are one-off scripts developed to perform specific scalability tests for Origin.
###Master-etcd-scale.go: This script's purpose is to scale an openshift origin system using a pre-defined template and assuming that each user will be created with one project.
-admin_kubeconfig string
Kubeconfig file for the system:admin user. (default "/openshift.local.config/master/admin.kubeconfig")
-app_template string
Application template to use when creating applications. Must include the parameter APP_IDENTIFIER in resource names to allow multiple apps per user.
-apps_per_user int
Number of per user to create. (default 1)
-cleanup
Delete temporary directory and files during test. (default true)
-host string
OpenShift master hostname (default "localhost")
-port int
OpenShift master api port (default 8443)
-registry_kubeconfig string
Kubeconfig file for the system:registry user. (default "/openshift.local.config/master/openshift-registry.kubeconfig")
-router_kubeconfig string
Kubeconfig file for the system:router user. (default "/openshift.local.config/master/openshift-router.kubeconfig")
-startnum int
Identifying user number to start from
-threads int
Maximum threads to utilize. (default 500)
-tmp_dir string
Temporary directory to store files created during test. Directory will be deleted after test by default. (default "/tmp/os-scale-test/")
-users int
Number of users to create.
-verbose
Be verbose with output.
Note that this test requires a template be provided. An example template has been provided at 'templates/Master-template_example.json'
###Node-PodWatcher.go
The purpose of this script is to determine possible pod limits for a node and to determine the difference in time pods take to create depending on how many pods a node currently has. This script is a derivitive of the Master-etcd-scale.go. There is no concurrency. Instead, templates will be created one-at-a-time. Pods created by each template will be watched in etcd. The time it takes for the pod to go from being created in etcd until it is in RUNNING state is recorded.
-admin_kubeconfig string
Kubeconfig file for the system:admin user. (default "/openshift.local.config/master/admin.kubeconfig")
-app_template string
Application template to use when creating applications. Must include the parameter APP_IDENTIFIER in resource names to allow multiple apps per user.
-apps_per_user int
Number of apps per user to create. (default 1)
-ca_crt string
CA certificate for use with the master and etcd API's (default "/openshift.local.config/master/ca.crt")
-cleanup
Delete temporary directory and files during test. (default true)
-etcd_client_crt string
Etcd client certificate (default "/openshift.local.config/master/master.etcd-client.crt")
-etcd_client_key string
Etcd client key (default "/openshift.local.config/master/master.etcd-client.key")
-host string
OpenShift master hostname (default "localhost")
-port int
OpenShift master api port (default 8443)
-registry_kubeconfig string
Kubeconfig file for the system:registry user. (default "/openshift.local.config/master/openshift-registry.kubeconfig")
-replicas int
Number of pods per app. (default 3)
-router_kubeconfig string
Kubeconfig file for the system:router user. (default "/openshift.local.config/master/openshift-router.kubeconfig")
-threads int
Maximum threads to utilize. (default 500)
-tmp_dir string
Temporary directory to store files created during test. Directory will be deleted after test by default. (default "/tmp/os-scale-test/")
-users int
Number of users to create.
-verbose
Be verbose with output.
This test creates from a template, but the template is embedded in the script due to the need to specify a specific number of replicas and this test's reliance on pod creation.
