     4  
     5  If you're using containerd as a Kubernetes [CRI] implementation, containerd
     6  uses the ["pause" image][pause] from Kubernetes in every pod.
     7  You may want to mirror this critical image to your own host.
     8  
     9  The version used by default can be found by `containerd config default | grep sandbox_image`.
    10  
    11  Containerd config is generally at `/etc/containerd/config.toml` and may contain
    12  a customized "sandbox image" rather than the default, for more details see:
    13  https://github.com/containerd/containerd/blob/main/docs/cri/config.md#registry-configuration

    15  ## Mirroring Images
    16  
    17  See our general list of [mirroring options](./README.md#Mirroring-Images)
    18  
    19  # Using Mirrored Images
    20  
    21  
    22  You may want to configure `sandbox_image` under `[plugins."io.containerd.grpc.v1.cri"]`
    23  to point to your own mirrored image for "pause".
    24  
    25  `containerd` also supports configuring mirrors for registry hosts.
