CLI Flags
Etcd-druid exposes the following CLI flags that allow for configuring its behavior.
| CLI FLag | Component | Description | Default |
|---|---|---|---|
feature-gates | etcd-druid | A set of key=value pairs that describe feature gates for alpha/experimental features. Please check feature-gates for more information. | "" |
metrics-bind-address | controller-manager | The IP address that the metrics endpoint binds to. | "" |
metrics-port | controller-manager | The port used for the metrics endpoint. | 8080 |
metrics-addr | controller-manager | The fully qualified address:port that the metrics endpoint binds to. Deprecated: this field will be eventually removed. Please use --metrics-bind-address and –metrics-port instead. | ":8080" |
webhook-server-bind-address | controller-manager | The IP address on which to listen for the HTTPS webhook server. | "" |
webhook-server-port | controller-manager | The port on which to listen for the HTTPS webhook server. | 9443 |
webhook-server-tls-server-cert-dir | controller-manager | The path to a directory containing the server’s TLS certificate and key (the files must be named tls.crt and tls.key respectively). | "/etc/webhook-server-tls" |
enable-leader-election | controller-manager | Enable leader election for controller manager. Enabling this will ensure there is only one active controller manager. | false |
leader-election-id | controller-manager | Name of the resource that leader election will use for holding the leader lock. | "druid-leader-election" |
leader-election-resource-lock | controller-manager | Specifies which resource type to use for leader election. Supported options are ’endpoints’, ‘configmaps’, ’leases’, ’endpointsleases’ and ‘configmapsleases’. Deprecated. Will be removed in the future in favour of using only leases as the leader election resource lock for the controller manager. | "leases" |
disable-lease-cache | controller-manager | Disable cache for lease.coordination.k8s.io resources. | false |
etcd-workers | etcd-controller | Number of workers spawned for concurrent reconciles of etcd spec and status changes. If not specified then default of 3 is assumed. | 3 |
ignore-operation-annotation | etcd-controller | Specifies whether to ignore or honour the annotation gardener.cloud/operation: reconcile on resources to be reconciled.Deprecated: please use --enable-etcd-spec-auto-reconcile instead. | false |
enable-etcd-spec-auto-reconcile | etcd-controller | If true then automatically reconciles Etcd Spec. If false, waits for explicit annotation gardener.cloud/operation: reconcile to be placed on the Etcd resource to trigger reconcile. | false |

enable-backup-compaction | compaction-controller | Enable automatic compaction of etcd backups. | false |

etcd-events-threshold | compaction-controller | Total number of etcd events that can be allowed before a backup compaction job is triggered. | 1000000 |
active-deadline-duration | compaction-controller | Duration after which a running backup compaction job will be terminated. | 3h |

etcd-copy-backups-task-workers | etcdcopybackupstask-controller | Number of worker threads for the etcdcopybackupstask controller. | 3 |
secret-workers | secret-controller | Number of worker threads for the secrets controller. | 10 |
