If you're using cri-o as a Kubernetes CRI implementation, cri-o uses the "pause" image from Kubernetes to implement pods. You may want to mirror this critical image to your own host.
The pause image confiured can be found by running:
cri-o config | grep pause_imageSee our general list of mirroring options
For pause see pause_image in the cri.image config docs:
https://github.com/cri-o/cri-o/blob/main/docs/crio.conf.5.md#crioimage-table
cri-o also supports configuring mirrors for registry hosts, which is documented at: https://github.com/containers/image/blob/main/docs/containers-registries.conf.5.md
You can use containers-registries.conf to configure a mirror for registry.k8s.io
