How to work with disconnected clusters

create a project in your local registry (for example gubernat-mirror)
set the variable repo_mirror in ./inventory.yaml to this mirror project:
repo_mirror: registry.my.domain/gubernat-mirror
on an internet connected host execute the mirror script:
./gubernat/tools/image-mirror.py -v registry.my.domain/gubernat-mirror gubernat/imagelist.csv
or generate the list and execute the commands on an internet connected host:
./gubernat/tools/image-mirror.py -n registry.my.domain/gubernat-mirror gubernat/imagelist.csv
and now you can install like you were internet connected ;-)

Generate image list for mirror images

update images.txt in the top repo folder
update all the images: definitions in `./components/*/kustomization.yaml``
run the following command to generate a new imagelist.csv:
cat images.txt| awk '{print $1 ",__REPOMIRROR__/" $1}' > imagelist.csv

/opt/kubernetes/components/*
(there you can do: kubectl kustomize . | grep image: | sort -u | awk '{ print $2 }')
crictl ps -a
kubeadm config images list
