In your [containerd config](https://github.com/containerd/containerd/blob/main/docs/cri/config.md) you can overwrite the
sandbox image by setting the following config:

```toml
{{< tabs name="containerd config" >}}
{{< tab name="containerd 2.x" codelang="toml" >}}
```
[plugins."io.containerd.grpc.v1.cri"]
sandbox_image = "registry.k8s.io/pause:3.2"
```
{{< /tab >}}
{{< tab name="containerd 1.x" codelang="toml" >}}
```
[plugins.'io.containerd.cri.v1.runtime']
sandbox_image = "registry.k8s.io/pause:3.2"
```

You might need to restart `containerd` as well once you've updated the config file: `systemctl restart containerd`.
