What is the docker image that is being used when we create an instance using SkyPilot

[hessiowork]

I was wondering what container image is being used on the instance that is rented when you run a job using SkyPilot? Can/How would you change the image used?

trying to find this info myself (seems undocumented :/ ) - the skypilot team publishes https://hub.docker.com/r/berkeleyskypilot/skypilot .

When I do sky launch --cloud kubernetes I can see my kubernetes pulling us-central1-docker.pkg.dev/skypilot-375900/skypilotk8s/skypilot:20240613

Thanks for the report, we are adding this to our docs: https://github.com/skypilot-org/skypilot/pull/4129/files

On clouds, we do not run in a container by default. The base VM image depends on the clouds chosen - you can refer to images.csv in our catalog: https://github.com/skypilot-org/skypilot-catalog/tree/master/catalogs/v5

On Kubernetes, we maintain and use two SkyPilot container images:

1. us-central1-docker.pkg.dev/skypilot-375900/skypilotk8s/skypilot: used for CPU-only clusters (Dockerfile).
2. us-central1-docker.pkg.dev/skypilot-375900/skypilotk8s/skypilot-gpu: used for GPU clusters (Dockerfile).

These images are pre-installed with SkyPilot dependencies for fast startup.
