我怎样才能解决这个 getaddrinfo 错误？我的想法是，这是 sidekiq 和 redis 之间的某种连接错误。我的 sidekiq.rb 配置文件中也有这个

 Sidekiq.configure_server do |config|
      config.redis = { url: 'redis://redis:6379' }
    end

提前致谢。抱歉，如果我的帖子有点模棱两可。随便问什么。 :)

编辑:我使用这个 sidekiq.rb 文件部署了基本的 Rails 应用程序(可以在端口 localhost:3000 上收听它)但是现在我得到了这个错误

web_1  | /usr/local/bundle/gems/redis-4.0.1/lib/redis/connection/ruby.rb:210:in `getaddrinfo': getaddrinfo: Name or service not known (SocketError)

sidekiq.rb 文件:

Sidekiq.configure_server do |config|
  config.redis = { url: 'redis://redis:6379' }
end
Sidekiq.configure_client do |config|
    config.redis = { url: 'redis://redis:6379'}
end

JazzWorker.perform_async

更新:修复了 redis 错误现在面临 dockerizing POSTGRES 的问题在 localhost:3000 上运行应用程序时，我收到此错误消息:https://imgur.com/a/YXw8N

我的 docker-compose 文件:

services:
  postgres:
    image: 'postgres:9.6'
    environment:
      - PGDATA=/var/lib/postgresql/data/pgdata

Answer 1

Dockerfile 用于构建镜像，而不是用于运行守护进程。 docker build 的结果是一个静态的东西(docker image)。我建议你直接从 docker-compose.yml 运行 redis

redis:
  image: redis

radiofm:
  (...)
  depends_on: redis
  (...)

PostgreSQL 的情况类似。如果你真的想在容器启动时设置你的图像以运行守护进程，你应该用脚本调整 CMD。

此外，您只能使用一次 CMD。
