If you are deploying Dapr on Amazon EKS and using an overlay network such as Calico, you will need to set `hostNetwork` parameter to true, this is a limitation of EKS with such CNIs.
You can set this parameter using Helm `values.yaml` file:
```
helm upgrade --install dapr dapr/dapr \
--namespace dapr-system \
--create-namespace \
--values values.yaml
```
`values.yaml`
```yaml
dapr_sidecar_injector:
hostNetwork: true
```
or using command line:
```
helm upgrade --install dapr dapr/dapr \
--namespace dapr-system \
--create-namespace \
--set dapr_sidecar_injector.hostNetwork=true
```
