The workspace is owned by root (COPY is executed as root user) but later switched to a non-root user. This will cause permission issues when the non-root user tries to write to the workspace. Consider changing ownership of the workspace after copying: RUN chown -R ${USER_ID}:${GROUP_ID} ${WORKSPACE}

[nitpick] The groupadd and useradd commands use || true to suppress errors if the user/group already exists, but this silently ignores all errors including genuine failures. Consider using more specific error handling or checking if the user exists first.

Suggested change

	RUN groupadd --gid ${GROUP_ID} ${USERNAME} || true && \
	useradd --uid ${USER_ID} --gid ${GROUP_ID} -m -s /bin/bash ${USERNAME} || true && \
	RUN if ! getent group ${USERNAME} >/dev/null; then groupadd --gid ${GROUP_ID} ${USERNAME}; fi && \
	if ! id -u ${USERNAME} >/dev/null 2>&1; then useradd --uid ${USER_ID} --gid ${GROUP_ID} -m -s /bin/bash ${USERNAME}; fi && \

ignoring this. removing "|| true" creates problems for mac users (and possibly windows), as it uses different ids automatically assigned.
