Question

一年中断后，我尝试使用docker / docker-compose运行默认的Rails 6项目。

起初，我遇到捆绑器问题。但这是通过[XmlInclude(typeof(Person))] [Serializable] public class Person ...

解决的

现在我遇到了纱线问题。您能否看一下以下配置并告诉我我做错了什么。谢谢！

Dockerfile

ENV BUNDLER_VERSION 2.0.1

docker-compose.yml

FROM ruby:2.6.3

RUN apt-get update -qq && apt-get install -y nodejs yarn postgresql-client

RUN mkdir -p /app
WORKDIR /app
COPY . /app

ENV BUNDLER_VERSION 2.0.1

RUN gem install bundler && bundle install --jobs 20 --retry 5
RUN yarn install

EXPOSE 3000
CMD ["bundle", "exec", "rails", "server", "-b", "0.0.0.0"]

这是FROM ruby:2.6.3 version: '3' services: db: image: postgres volumes: - ./tmp/db:/var/lib/postgresql/data web: build: . command: bash -c "rm -f tmp/pids/server.pid && bundle exec rails s -p 3000 -b '0.0.0.0'" volumes: - .:/myapp ports: - "3000:3000" depends_on: - db的输出在安装了gem之后，我可以看到以下输出：

docker-compose build

编辑

如果我使用以下Dockerfile，它将起作用。但是我认为这不是最好的解决方案。

有时在使用apt来安装yarn时在主机上安装了cmdtest可能会导致问题尝试执行以下操作：

RUN apt-get remove -y cmdtest && apt-get update -qq && apt-get install -y nodejs postgresql-client

然后使用脚本安装yrn：

curl -o- -L https://yarnpkg.com/install.sh | bash

如果仍然无法正常工作，请参阅此commit

我的Dockerfile的前几行如下：

FROM ruby:2.5.1

# Ensure we install an up-to-date version of Node
# See https://github.com/yarnpkg/yarn/issues/2888
RUN curl -sL https://deb.nodesource.com/setup_8.x | bash -

# Ensure latest packages for Yarn
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list

# Allow apt to work with https-based sources
RUN apt-get update -yqq && apt-get install -yqq --no-install-recommends \
    apt-transport-https \
    nodejs \
    postgresql-client \
    yarn

Dockerfile应该如何使用yarn运行默认的rails 6项目？
