ruby-on-rails - Ruby 2.7 和 Rails 7 的 Docker 配置

Question

在将 Rails 应用程序升级到 Rails 7 后，我正在尝试将其容器化
下面是我的 docker 文件的相关部分

FROM ubuntu:20.04

#https://www.postgresql.org/download/linux/ubuntu/
RUN apt-get update && apt-get install -y gnupg wget
RUN echo "deb http://apt.postgresql.org/pub/repos/apt bionic-pgdg main" > /etc/apt/sources.list.d/pgdg.list
# Import the repository signing key:
RUN wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -

RUN apt-get update && apt-get dist-upgrade -y && DEBIAN_FRONTEND=noninteractive apt-get install -y nodejs ruby-dev bundler build-essential zlib1g-dev libpq-dev tzdata git curl postgresql-client-12 imagemagick && rm -rf /var/lib/apt/lists/*

RUN useradd -m deploy

WORKDIR /app

COPY Gemfile* ./
RUN mkdir -p vendor
COPY vendor/cache vendor/cache
RUN bundle config set deployment 'true'
RUN bundle config set without 'test development'
RUN bundle install

我看到以下错误

#17 1.447 Don't run Bundler as root. Bundler can ask for sudo if it is needed, and

关于如何解决这个问题的任何帮助都会非常棒，谢谢。

添加用户后，您需要切换到它以使后续命令不再以 root 身份运行:

RUN useradd -m deploy
USER deploy
