cert-manager CA injector is a Kubernetes addon to automate the injection of CA data into
webhooks and APIServices from cert-manager certificates.
It will ensure that annotated webhooks and API services always have the correct
CA data from the referenced certificates, which can then be used to serve API
servers and webhook servers.
--add_dir_header If true, adds the file directory to the header of the log messages
--alsologtostderr log to standard error as well as files
--enable-profiling Enable profiling for cainjector
--feature-gates mapStringBool A set of key=value pairs that describe feature gates for alpha/experimental features. Options are:
AllAlpha=true|false (ALPHA - default=false)
AllBeta=true|false (BETA - default=false)
-h, --help help for ca-injector
--kubeconfig string Paths to a kubeconfig. Only required if out-of-cluster.
--leader-elect If true, cainjector will perform leader election between instances to ensure no more than one instance of cainjector operates at a time (default true)
--leader-election-lease-duration duration The duration that non-leader candidates will wait after observing a leadership renewal until attempting to acquire leadership of a led but unrenewed leader slot. This is effectively the maximum duration that a leader can be stopped before it is replaced by another candidate. This is only applicable if leader election is enabled. (default 1m0s)
--leader-election-namespace string Namespace used to perform leader election. Only used if leader election is enabled (default "kube-system")
--leader-election-renew-deadline duration The interval between attempts by the acting master to renew a leadership slot before it stops leading. This must be less than or equal to the lease duration. This is only applicable if leader election is enabled. (default 40s)
--leader-election-retry-period duration The duration the clients should wait between attempting acquisition and renewal of a leadership. This is only applicable if leader election is enabled. (default 15s)
--log-flush-frequency duration Maximum number of seconds between log flushes (default 5s)
--log_backtrace_at traceLocation when logging hits line file:N, emit a stack trace (default :0)
--log_dir string If non-empty, write log files in this directory
--log_file string If non-empty, use this log file
--log_file_max_size uint Defines the maximum size a log file can grow to. Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
--logtostderr log to standard error instead of files (default true)
--namespace string If set, this limits the scope of cainjector to a single namespace. If set, cainjector will not update resources with certificates outside of the configured namespace.
--one_output If true, only write logs to their native severity level (vs also writing to each lower severity level)
--profiler-address string Address of the Go profiler (pprof) if enabled. This should never be exposed on a public interface. (default "localhost:6060")
--skip_headers If true, avoid header prefixes in the log messages
--skip_log_headers If true, avoid headers when opening log files
--stderrthreshold severity logs at or above this threshold go to stderr (default 2)
-v, --v Level number for the log level verbosity
--vmodule moduleSpec comma-separated list of pattern=N settings for file-filtered logging
