我在使用docker和docker-compose运行我的rails应用程序时收到此错误 在127.0.0.1:6379上连接到Redis时出错(Errno :: ECONNREFUSED)
请找到我的Docker文件
# Copy the Gemfile as well as the Gemfile.lock and install
# the RubyGems. This is a separate step so the dependencies
# will be cached unless changes to one of those two files
# are made.
COPY Gemfile Gemfile.lock ./
RUN gem install bundler && bundle install --jobs 20 --retry 5
# Copy the main application.
COPY . ./app
# Expose port 3000 to the Docker host, so we can access it
# from the outside.
EXPOSE 3000
# The main command to run when the container starts. Also
# tell the Rails dev server to bind to all interfaces by
# default.
CMD ["bundle", "exec", "rails", "server", "-b", "0.0.0.0"]

我使用docker-compose并添加.env
文件
REDIS_URL=redis://redis:6379/0

Links不需要启用服务进行通信 - 默认情况下,任何服务都可以通过该服务的名称访问任何其他服务。
根据您的docker-compose.yaml文件,您只能从主机访问127.0.0.1:6379上的redis容器。
容器在其网络中相互通信,因此您可以从rails app容器访问redis:6379
上的redis容器。
