Ubuntu 为Dockerfile中的所有案例设置区域设置和时区

我试图涵盖Dockerfile中设置区域设置和时区的所有情况。我写了以下内容，但感觉有些过分：

# Set for current session
ENV LC_ALL="en_US.UTF-8" \
    LANG="en_US.UTF-8" \
    LANGUAGE="en_US.UTF-8" \
    TZ="UTC"

# Install locales
    # Uncomment en_US.UTF-8 locales in /etc/locale.gen file
RUN sed --in-place '/en_US.UTF-8/s/^# //' /etc/locale.gen && \
    # Generate new locales from /etc/locale.gen file
    locale-gen && \
    # Set system locale for login shells
    echo "export LC_ALL=en_US.UTF-8" >> /etc/profile && \
    echo "export LANG=en_US.UTF-8" >> /etc/profile && \
    echo "export LANGUAGE=en_US.UTF-8" >> /etc/profile && \
    # Set system timezone for login shells
    echo "export TZ=UTC" >> /etc/profile && \
    # Set system locale for non-login shells for root
    echo "export LC_ALL=en_US.UTF-8" >> ~/.bashrc && \
    echo "export LANG=en_US.UTF-8" >> ~/.bashrc && \
    echo "export LANGUAGE=en_US.UTF-8" >> ~/.bashrc && \
    # Set system timezone for non-login shells for root
    echo "export TZ=UTC" >> ~/.bashrc

正如你所看到的，我试图（为bash ofc）报道：

• 本届会议
• 所有用户的登录shell
• 所有用户的非登录shell

以上是不是太过分了？不对？是否有更合适的方式涵盖所有案例
