+# Tekton Controllers flags
+
+The different controllers `tektoncd/pipeline` ships comes with a set of flags
+that can be changed (in the `yaml` payloads) for advanced use cases. This page
+is documenting them.
+
+## Common set of flags
+
+The following flags are available on all "controllers", aka `controller`, `webhook`, `events` and `resolvers`.
+
+```
+  -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 (no effect when -logtostderr=true)
+  -cluster string
+        Defaults to the current cluster in kubeconfig.
+  -disable-ha
+        Whether to disable high-availability functionality for this component.  This flag will be deprecated and removed when we have promoted this feature to stable, so do not pass it without filing an issue upstream!
+  -kube-api-burst int
+        Maximum burst for throttle.
+  -kube-api-qps float
+        Maximum QPS to the server from the client.
+  -kubeconfig string
+        Path to a kubeconfig. Only required if out-of-cluster.
+  -log_backtrace_at value
+        when logging hits line file:N, emit a stack trace
+  -log_dir string
+        If non-empty, write log files in this directory (no effect when -logtostderr=true)
+  -log_file string
+        If non-empty, use this log file (no effect when -logtostderr=true)
+  -log_file_max_size uint
+        Defines the maximum size a log file can grow to (no effect when -logtostderr=true). 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)
+  -one_output
+        If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
+  -server string
+        The address of the Kubernetes API server. Overrides any value in kubeconfig. Only required if out-of-cluster.
+  -skip_headers
+        If true, avoid header prefixes in the log messages
+  -skip_log_headers
+        If true, avoid headers when opening log files (no effect when -logtostderr=true)
+  -stderrthreshold value
+        logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=false) (default 2)
+  -v value
+        number for the log level verbosity
+  -vmodule value
+        comma-separated list of pattern=N settings for file-filtered logging
+```
+
+## `controller`
+
+The main controller binary has additional flags to configure its behavior.
+
+```
+  -entrypoint-image string
+        The container image containing our entrypoint binary.
+  -namespace string
+        Namespace to restrict informer to. Optional, defaults to all namespaces.
+  -nop-image string
+        The container image used to stop sidecars
+  -resync-period duration
+        The period between two resync run (going through all objects) (default 10h0m0s)
+  -shell-image string
+        The container image containing a shell
+  -shell-image-win string
+        The container image containing a windows shell
+  -sidecarlogresults-image string
+        The container image containing the binary for accessing results.
+  -threads-per-controller int
+        Threads (goroutines) to create per controller (default 2)
+  -workingdirinit-image string
+        The container image containing our working dir init binary.
+```
