### Cluster Created by Kubeadm
If you are using kubeadm with a [configuration file](https://kubernetes.io/docs/reference/setup-tools/kubeadm/kubeadm-init/#config-file), you have to add `mode: ipvs` and also add `SupportIPVSProxyMode: true` below the `kubeProxy` field as part of the kubeadm configuration.
If you are using kubeadm with a [configuration file](https://kubernetes.io/docs/reference/setup-tools/kubeadm/kubeadm-init/#config-file), you have to add `mode: ipvs` below the `kubeProxy` field as part of the kubeadm configuration.
```yaml
...
kubeProxy:
config:
featureGates:
SupportIPVSProxyMode: true
mode: ipvs
...
```
Note that in Kubernetes 1.11 and later, `SupportIPVSProxyMode` is set to `true` by default.
before running
`kube init --config <path_to_configuration_file>`
If you are using Kubernetes v1.8, you can also add the flag `--feature-gates=SupportIPVSProxyMode=true` (deprecated since v1.9) in `kubeadm init` command
```
kubeadm init --feature-gates=SupportIPVSProxyMode=true
```
to specify the ipvs mode before deploying the cluster.

Use the following check list to help you solve the problems:
**1. Enable IPVS feature gateway**
For Kubernetes v1.10 and later, feature gate `SupportIPVSProxyMode` is set to `true` by default. However, you need to enable `--feature-gates=SupportIPVSProxyMode=true` explicitly for Kubernetes before v1.10.
**2. Specify proxy-mode=ipvs**
**1. Specify proxy-mode=ipvs**
Check whether the kube-proxy mode has been set to `ipvs`.
**3. Install required kernel modules and packages**
**2. Install required kernel modules and packages**
Check whether the IPVS required kernel modules have been compiled into the kernel and packages installed. (see Prerequisite)
