Run with Root User Privileges

Flower Docker images, by default, run with a non-root user (username/groupname: app, UID/GID: 49999). Using root user is not recommended unless it is necessary for specific tasks during the build process.

Always make sure to run the container as a non-root user in production to maintain security best practices.

Run a Container with Root User Privileges

-u 플래그를 사용하여 Docker 이미지를 실행하고 사용자 이름으로 ``root``를 지정합니다:

$ docker run --rm -u root flwr/superlink:1.15.2 <additional-args>

이 명령은 루트 사용자 권한으로 Docker 컨테이너를 실행합니다.

Run the Build Process with Root User Privileges

Docker 이미지 빌드 과정에서 루트 사용자로 전환하여 누락된 시스템 의존성을 설치하려면 Dockerfile 내에서 USER root 지시어를 사용할 수 있습니다.

SuperNode Dockerfile

FROM flwr/supernode:1.15.2

# Switch to root user
USER root

# Install missing dependencies (requires root access)
RUN apt-get update && apt-get install -y <required-package-name>

# Switch back to non-root user app
USER app

# Continue with your Docker image build process
