How to find the Dockerfile for this image?

There is no Dockerfile for that image.

The gcr.io/distroless/base image is built from this repository. If you read through the README, you'll find:

How do I use distroless images?

These images are built using bazel, but they can also be used through other Docker image build tooling.

Bazel is a build tool that can be used to create Docker images.

What does distroless image mean?

That means the image isn't based on any particular distribution; it includes only a minimal set of files so that the final image contains only what is strictly necessary to run your application:

  • ca-certificates
  • A /etc/passwd entry for a root user
  • A /tmp directory
  • tzdata
  • glibc
  • libssl
  • openssl
