This page describes how to configure Metacontroller.
[[TOC]]
The Metacontroller server has a few settings that can be configured
with command-line flags (by editing the Metacontroller StatefulSet
in manifests/metacontroller.yaml):
| Flag | Description |
|---|---|
--zap-log-level |
ZapGws Level to configure the verbosity of logging. Can be one of ‘debug’, ‘info’, ‘error’, or any integer value > 0 which corresponds to custom debug levels of increasing verbosity(e.g. --zap-log-level=5). Level 4 logs Metacontroller's interaction with the API server. Levels 5 and up additionally log details of Metacontroller's invocation of lambda hooks. See the troubleshooting guide for more. |
--zap-devel |
Development Mode (e.g. --zap-devel) defaults(encoder=consoleEncoder,logLevel=Debug,stackTraceLevel=Warn). |
--zap-encoder |
Zap log encoding - json or console (e.g. --zap-encoder='json') defaults(encoder=consoleEncoder,logLevel=Debug,stackTraceLevel=Warn). |
--zap-stacktrace-level |
Zap Level at and above which stacktraces are captured - one of info or error (e.g. --zap-stacktrace-level='info'). |
--discovery-interval |
How often to refresh discovery cache to pick up newly-installed resources (e.g. --discovery-interval=10s). |
--cache-flush-interval |
How often to flush local caches and relist objects from the API server (e.g. --cache-flush-interval=30m). |
--metrics-address |
The address to bind metrics endpoint - /metrics (e.g. --metrics-address=":9999"). It can be set to "0" to disable the metrics serving. |
--kubeconfig |
Path to kubeconfig file (same format as used by kubectl); if not specified, use in-cluster config (e.g. --kubeconfig=/path/to/kubeconfig). |
--client-go-qps |
Number of queries per second client-go is allowed to make (default 5, e.g. --client-go-qps=100) |
--client-go-burst |
Allowed burst queries for client-go (default 10, e.g. --client-go-burst=200) |
--workers |
Number of sync workers to run (default 5, e.g. --workers=100) |
--events-qps |
Rate of events flowing per object (default - 1 event per 5 minutes, e.g. --events-qps=0.0033) |
--events-burst |
Number of events allowed to send per object (default 25, e.g. --events-burst=25) |
Logging flags are being set by controller-runtime, more on the meaning of them can be found here
