@joneszc has the script we used to generate that list.

[viniciusdc]

@joneszc, it would be great to compare your script with the idea above, as I think some images are missing, such as the /registry ones in there. Even if this does not go directly to this PR, I think we could extend this later to have a broad view of all images.

I am happy to chat about if you need

Hello @viniciusdc @tylergraff ,

Rather than using a script I'm using kubectl to collect pods at two stages: 1) immediately following deployment of Nebari; and 2) after launching a jupyterlab user node
kubectl get pods --all-namespaces -o jsonpath="{.items[*].spec['initContainers', 'containers'][*].image}" | tr -s '[[:space:]]' '\n' | sort | uniq -c

I devoted time several months ago to creating a branch for enabling pin-pointed specification, mostly leveraging terraform overrides, of each container-image used by Nebari. Not sure if it's is helpful for this PR, but the following nebari-config.yaml example shows possible overrides for each container-image and at least serves as a reference for where (i.e. in which chart) each image is invoked, as of a few releases past.
