Pipelines: known_host file is not updated to non-root user directory

Summary

With Docker image logged as non-root, the build is unable to get the host's fingerprint which had fetch in the Pipelines Settings.
Tried to run "cat ~/.ssh/known_hosts" in the build and the known_host file is empty
Ran "cat /opt/atlassian/pipelines/agent/data/known_hosts" and getting "cat: /opt/atlassian/pipelines/agent/data/known_hosts: Permission denied" error.

Example:
Build image - Dockerfile:

#!python
FROM node:argon

RUN apt-get update
RUN apt-get -y dist-upgrade
RUN apt-get install --no-install-recommends -y -q sudo curl python build-essential git ca-certificates

RUN adduser --disabled-password --gecos '' myuser
RUN usermod -aG sudo myuser
RUN echo '%sudo ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers

USER myuser

Workaround

1. Add the Host key to known_host file. "ssh-keyscan <Host Address> >> ~/.ssh/known_hosts"
2. Allow your build to run as root user by removing "USER myuser" from the Dockerfile
