sky launch problem with cluster kubernetes

[taigetco]

Run sky in an environment with limited network access. Download the image in advance: us-central1-docker.pkg.dev/skypilot-375900/skypilotk8s/skypilot:20240321 and import the image into the containerd directory. However, kubelet will also download it when it starts. Investigation found that it was in the file kubernetes-ssh-jump.yml.j2, which sets imagePullPolicy: Always. I modified it in the local environment sky directory: sky/lib/python3.10/site-packages/sky/templates/kubernetes-ingress.yml.j2, and set imagePullPolicy: IfNotPresent.
But sky launch did not take effect again, and it still downloaded. The question I want to ask is, is the place I changed correct, or can it not be changed?

Hey @taigetco - changing imagePullPolicy in sky/templates/kubernetes-ssh-jump.yml.j2 is all that should be required-

skypilot/sky/templates/kubernetes-ssh-jump.yml.j2

Line 17 in 90f8e89

imagePullPolicy: Always

We will also soon be removing the SSH jump pod, so this should no longer be necessary after this PR: #3577
