| parameter | type | default | describe | | :-: | :-: | :-: | :-: | | use-webhook | bool | false | Enable Admission Webhook | | webhook-cert-dir | string | /k8s-webhook-server/serving-certs | Admission webhook cert/key dir. | | webhook-port | int | 9443 | Admission webhook listen address | | metrics-addr | string | :8080 | The address the metric endpoint binds to. | | enable-leader-election | bool | false | Enable leader election for controller manager. Enabling this will ensure there is only one active controller manager. | | leader-election-namespace | string | "" | Determines the namespace in which the leader election configmap will be created. | | log-file-path | string | "" | The file to write logs to. | | log-file-max-size | int | 1024 | Defines the maximum size a log file can grow to, Unit is megabytes. | | log-debug | bool | false | Enable debug logs for development purpose | | revision-limit | int | 50 | revision-limit is the maximum number of revisions that will be maintained. The default value is 50. | | application-revision-limit | int | 10 | application-revision-limit is the maximum number of application useless revisions that will be maintained, if the useless revisions exceed this number, older ones will be GCed first.The default value is 10. | | definition-revision-limit | int | 20 | definition-revision-limit is the maximum number of component/trait definition useless revisions that will be maintained, if the useless revisions exceed this number, older ones will be GCed first.The default value is 20. | | app-config-installed | bool | true | app-config-installed indicates if applicationConfiguration CRD is installed | | autogen-workload-definition | bool | true | Automatic generated workloadDefinition which componentDefinition refers to | | health-addr | string | :9440 | The address the health endpoint binds to. | | apply-once-only | string | false | For the purpose of some production environment that workload or trait should not be affected if no spec change, available options: on, off,

| | storage-driver | string | Local | Application file save to the storage driver | | application-re-sync-period | time | 5m | Re-sync period for application to re-sync, also known as the state-keep interval. | | reconcile-timeout | time | 3m | The timeout for controller reconcile. | | system-definition-namespace | string | vela-system | define the namespace of the system-level definition | | concurrent-reconciles | int | 4 | The concurrent reconcile number of the controller. You can increase the degree of concurrency if a large number of CPU cores are provided to the controller. | | kube-api-qps | int | 50 | The qps for reconcile k8s clients. Increase it if you have high concurrency. A small number might restrict the requests to the api-server which may cause a long waiting queue when there are a large number of inflight requests. Try to avoid setting it too high since it will cause large burden on apiserver. | | kube-api-burst | int | 100 | The burst for reconcile k8s clients. The usage of this parameter is similar to kube-api-qps. Setting it to be larger than kube-api-qps allows accepting more requests temporarily. | | depend-check-wait | time | 30s | depend-check-wait is the time to wait for ApplicationConfiguration's dependent-resource ready. | | oam-spec-var | string | v0.3 | the oam spec version controller want to set-up | | pprof-addr | string | "" | The address for pprof to use while profiling, empty means disable. | | perf-enabled | bool | false | Enable performance logging for controllers, disabled by default. | | Scale | #Nodes | #Applications | #Pods | concurrent-reconciles | kube-api-qps | kube-api-burst | CPU | Memory | | :: | -: | : | -: | --: | :-: | -: | -: | --: | | Small | < 200 | < 3,000 | < 18,000 | 2 | 300 | 500 | 0.5 | 1Gi | | Medium | < 500 | < 5,000 | < 30,000 | 4 | 500 | 800 | 1 | 2Gi | | Large | < 1,000 | < 12,000 | < 72,000 | 4 | 800 | 1,000 | 2 | 4Gi | For details, read KubeVela Performance Test Report
