对现有 Rails 应用程序进行 Docker 化
Dockerizing Existing Rails Application
我一直在尝试将我的 rails 应用程序移动到 docker 容器中,因为它曾经在开发环境的 virtualbox 中进行 ansible 管理。我查看了一些 docker 教程和一些特定于迁移 rails 应用程序的教程,但我 运行 遇到以下错误:

这是我尝试通过 docker-compose 运行 编写的简化 docker 文件。我最初将它连接到我的 MySQL 图像,但已将其删除以帮助调试,但错误仍然存在。
Docker 文件
FROM ruby:2.4.0

&& apt-get install -yqq --no-install-recommends \

我在以下 SO 线程中尝试了一些解决方案,但似乎无法消除错误:Specifying path to vendor/cache and installing rake before running bundle install
将我的解决方案放在这里以防万一有人遇到这个问题:
首先我更新了我的 docker 文件以执行以下操作
FROM ruby:2.4.0
RUN apt-get update -yqq \
&& apt-get install -yqq --no-install-recommends \
build-essential \
mysql-client \
nodejs \
supervisor \
vim \
lsof \
htop \
&& apt-get clean -q clean \
&& rm -rf /var/lib/apt/lists
RUN mkdir -p /my_api
ENV RAILS_ROOT /my_api
WORKDIR $RAILS_ROOT
COPY Gemfile ./
COPY . ./
COPY ./railsbox/ansible/group_vars/all/.env ./.env
RUN gem install bundler --no-ri --no-rdoc --version 1.17.3
RUN gem install rake --version 13.0.1 && bundle install --path vendor/cache --no-deployment
RUN gem list
CMD rm -f ./tmp/pids/server.pid && bundle exec rails s -b 0.0.0.0
注意 COPY 的变化。 ./.在 运行ning 捆绑包安装之前。这将避免在安装 运行(我相信)后覆盖 /vendor/cache。
我还更新了我的 docker-compose 设置,如下所示
api:
image: my_api
build:
context: .
dockerfile: ./docker/app/dockerfile
depends_on:
- mysql
- mysql_test
ports:
- "3000:3000"
working_dir: /my_api
volumes:
- ./:/my_api
- /my_api/vendor/cache
links:
- mysql
- mysql_test
请注意 /vendor/cache 的空白卷映射,如 中所建议的那样,它解释了关于 node_modules 的这一点。我相信通过此更改,您无需执行上述移动 COPY 的建议。 ./ 在捆绑包安装之前,但我将其保留原样,因为我认为这并不重要。
