cert-manager is a Kubernetes addon to automate the management and issuance of
TLS certificates from various issuing sources.
It will ensure certificates are valid and up to date periodically, and attempt
to renew certificates at an appropriate time before expiry.
--acme-http01-solver-image string The docker image to use to solve ACME HTTP01 challenges. You most likely will not need to change this parameter unless you are testing a new feature or developing cert-manager. (default "quay.io/jetstack/cert-manager-acmesolver:canary")
--acme-http01-solver-resource-limits-cpu string Defines the resource limits CPU size when spawning new ACME HTTP01 challenge solver pods. (default "100m")
--acme-http01-solver-resource-limits-memory string Defines the resource limits Memory size when spawning new ACME HTTP01 challenge solver pods. (default "64Mi")
--acme-http01-solver-resource-request-cpu string Defines the resource request CPU size when spawning new ACME HTTP01 challenge solver pods. (default "10m")
--acme-http01-solver-resource-request-memory string Defines the resource request Memory size when spawning new ACME HTTP01 challenge solver pods. (default "64Mi")
--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
--auto-certificate-annotations strings The annotation consumed by the ingress-shim controller to indicate a ingress is requesting a certificate (default [kubernetes.io/tls-acme])
--cluster-issuer-ambient-credentials Whether a cluster-issuer may make use of ambient credentials for issuers. 'Ambient Credentials' are credentials drawn from the environment, metadata services, or local files which are not explicitly configured in the ClusterIssuer API object. When this flag is enabled, the following sources for credentials are also used: AWS - All sources the Go SDK defaults to, notably including any EC2 IAM roles available via instance metadata. (default true)
--cluster-resource-namespace string Namespace to store resources owned by cluster scoped resources such as ClusterIssuer in. This must be specified if ClusterIssuers are enabled. (default "kube-system")
--controllers strings A list of controllers to enable. '--controllers=*' enables all on-by-default controllers, '--controllers=foo' enables just the controller named 'foo', '--controllers=*,-foo' disables the controller named 'foo'.
All controllers: issuers, clusterissuers, certificates-metrics, ingress-shim, orders, challenges, certificaterequests-issuer-acme, certificaterequests-approver, certificaterequests-issuer-ca, certificaterequests-issuer-selfsigned, certificaterequests-issuer-vault, certificaterequests-issuer-venafi, certificates-trigger, certificates-issuing, certificates-key-manager, certificates-request-manager, certificates-readiness, certificates-revision-manager (default [*])
--default-issuer-group string Group of the Issuer to use when the tls is requested but issuer group is not specified on the ingress resource. (default "cert-manager.io")
--default-issuer-kind string Kind of the Issuer to use when the tls is requested but issuer kind is not specified on the ingress resource. (default "Issuer")
--default-issuer-name string Name of the Issuer to use when the tls is requested but issuer name is not specified on the ingress resource.
--dns01-check-retry-period duration The duration the controller should wait between checking if a ACME dns entry exists.This should be a valid duration string, for example 180s or 1h (default 10s)
--dns01-recursive-nameservers strings A list of comma separated dns server endpoints used for DNS01 check requests. This should be a list containing host and port, for example 184.108.40.206:53,220.127.116.11:53
--dns01-recursive-nameservers-only When true, cert-manager will only ever query the configured DNS resolvers to perform the ACME DNS01 self check. This is useful in DNS constrained environments, where access to authoritative nameservers is restricted. Enabling this option could cause the DNS01 self check to take longer due to caching performed by the recursive nameservers.
--enable-certificate-owner-ref Whether to set the certificate resource as an owner of secret where the tls certificate is stored. When this flag is enabled, the secret will be automatically removed when the certificate resource is deleted.
--enable-profiling Enable profiling for controller.
--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)
ExperimentalCertificateSigningRequestControllers=true|false (ALPHA - default=false)
ValidateCAA=true|false (ALPHA - default=false)
-h, --help help for cert-manager-controller
--issuer-ambient-credentials Whether an issuer may make use of ambient credentials. 'Ambient Credentials' are credentials drawn from the environment, metadata services, or local files which are not explicitly configured in the Issuer API object. When this flag is enabled, the following sources for credentials are also used: AWS - All sources the Go SDK defaults to, notably including any EC2 IAM roles available via instance metadata.
--kube-api-burst int the maximum burst queries-per-second of requests sent to the Kubernetes apiserver (default 50)
--kube-api-qps float32 indicates the maximum queries-per-second requests to the Kubernetes apiserver (default 20)
--kubeconfig string Paths to a kubeconfig. Only required if out-of-cluster.
--leader-elect If true, cert-manager will perform leader election between instances to ensure no more than one instance of cert-manager 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)
--master string Optional apiserver host address to connect to. If not specified, autoconfiguration will be attempted.
--max-concurrent-challenges int The maximum number of challenges that can be scheduled as 'processing' at once. (default 60)
--metrics-listen-address string The host and port that the metrics endpoint should listen on. (default "0.0.0.0:9402")
--namespace string If set, this limits the scope of cert-manager to a single namespace and ClusterIssuers are disabled. If not specified, all namespaces will be watched
--one_output If true, only write logs to their native severity level (vs also writing to each lower severity level)
--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
