You can customize the EnvoyProxy using patches.

For example, the following configuration will add resource limits to the `envoy` and the `shutdown-manager` containers in the `envoyproxy` deployment:

```shell
cat <<EOF | kubectl apply -f -
apiVersion: gateway.envoyproxy.io/v1alpha1
kind: EnvoyProxy
metadata:
name: eg
namespace: envoy-gateway-system
spec:
provider:
type: Kubernetes
kubernetes:
envoyDeployment:
patch:
type: StrategicMerge
value:
spec:
template:
spec:
containers:
- name: envoy
resources:
limits:
cpu: 500m
memory: 1024Mi
- name: shutdown-manager
resources:
limits:
cpu: 200m
memory: 1024Mi
EOF
```

After applying the configuration, you will see the change in both containers in the `envoyproxy` deployment.
