'Cached Docker images on Hosted Linux Preview agent
We are building docker image on VSTS by using VSTS Hosted Linux Preview agent. microsoft/aspnetcore-build image is used to build asp.net core application. Each time build is triggered, an agent is pulling microsoft/aspnetcore-build image from registry and it takes some time. We would like to avoid this, by specifying specific image pre-cached on agents.
Is there a list of container images that have been cached on Hosted Linux Preview agent? Such information is available for Hosted VS2017 agent, but not for Linux one.

According to this documentation the complete list can be found in the following documents:
(*) The above are permalinks to a specific snapshot of code (dated 2022-03-26). For the most current data, switch to the "main" branch in GitHub. Note that files may disappear from the 'main' branch when image gets deprecated.
As of 2022-03-26, both images include the same set of pre-cached docker images which are:
alpine:3.12
alpine:3.13
alpine:3.14
buildpack-deps:bullseye
buildpack-deps:buster
buildpack-deps:stretch
debian:10
debian:11
debian:9
moby/buildkit:latest
node:12
node:12-alpine
node:14
node:14-alpine
node:16
node:16-alpine
ubuntu:16.04
ubuntu:18.04
ubuntu:20.04
This can also be confirmed by adding a simple task to the pipeline that runs docker image list. Here's an example of the command's output ran on Ubuntu-16.04 agent (before it was deprecated):
/usr/bin/docker image list
