| `dapr_operator.extraEnvVars` | Map of (name, value) tuples to use as extra environment variables (e.g. `my-env-var: "my-val"`, etc) | `{}` |

### Dapr Placement options:
| Parameter | Description | Default |
|------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------|
| `dapr_placement.ha` | If set to true, deploys the Placement service with 3 nodes regardless of the value of `global.ha.enabled` | `false` |
| `dapr_placement.replicationFactor` | Number of consistent hashing virtual node | `100` |
| `dapr_placement.logLevel` | Service Log level | `info` |
| `dapr_placement.image.name` | Service docker image name (`global.registry/dapr_placement.image.name`) | `dapr` |
| `dapr_placement.cluster.forceInMemoryLog` | Use in-memory log store and disable volume attach when HA is true | `false` |
| `dapr_placement.cluster.logStorePath` | Mount path for persistent volume for log store in unix-like system when HA is true | `/var/run/dapr/raft-log` |
| `dapr_placement.cluster.logStoreWinPath` | Mount path for persistent volume for log store in windows when HA is true | `C:\\raft-log` |
| `dapr_placement.volumeclaims.storageSize` | Attached volume size | `1Gi` |
| `dapr_placement.volumeclaims.storageClassName` | storage class name | |
| `dapr_placement.maxActorApiLevel` | Sets the `max-api-level` flag which prevents the Actor API level from going above this value. The Placement service reports to all connected hosts the Actor API level as the minimum value observed in all actor hosts in the cluster. Actor hosts with a lower API level than the current API level in the cluster will not be able to connect to Placement. Setting a cap helps making sure that older versions of Dapr can connect to Placement as actor hosts, but may limit the capabilities of the actor subsystem. The default value of -1 means no cap. | `-1` |
| `dapr_placement.minActorApiLevel` | Sets the `min-api-level` flag, which enforces a minimum value for the Actor API level in the cluster. | `0` |
| `dapr_placement.runAsNonRoot` | Boolean value for `securityContext.runAsNonRoot`. Does not apply unless `forceInMemoryLog` is set to `true`. You may have to set this to `false` when running in Minikube | `false` |
| `dapr_placement.resources` | Value of `resources` attribute. Can be used to set memory/cpu resources/limits. See the section "Resource configuration" above. Defaults to empty | `{}` |
| `dapr_placement.debug.enabled` | Boolean value for enabling debug mode | `{}` |
| `dapr_placement.metadataEnabled` | Boolean value for enabling placement tables metadata HTTP API | `false` |
| `dapr_placement.statefulsetAnnotations` | Custom annotations for Dapr Placement Statefulset | `{}` |
| `dapr_placement.service.annotations` | Custom annotations for "dapr-placement-server" Service resource | `{}` |
| `dapr_placement.extraEnvVars` | Map of (name, value) tuples to use as extra environment variables (e.g. `my-env-var: "my-val"`, etc) | `{}` |
