Docker-与redis、sidekiq、rails SocketError 组合
Docker-compose with redis, sidekiq, rails SocketError
我对 docker-compose 配置中的错误感到困惑。我正在将 redis 与 sidekiq 添加到现有的 rails 应用程序中，该应用程序使用 docker-compose 但我在尝试使容器相互通信时失败了。我尝试了几种不同的选择，并查看了几乎所有涉及该主题的合理主题，但我在基本相同的事情上一直失败。这是我当前的配置（或至少它的相关部分）和错误：
docker-compose.yml
services:
web:
<<: *common-settings
build:
context: .
dockerfile: docker/development/Dockerfile
target: web
command: dumb-init bash -c "(bundle check || bundle install) && rails s -b 0.0.0.0 -p 3000"
depends_on:
- db
- redis
- elasticsearch
ports:
- '3000:3000'
expose:
- 3000
redis:
image: 'redis:5-alpine'
ports:
- '6379:6379'
volumes:
- 'redis:/data'
sidekiq:
depends_on:
- db
- redis
- web
build: .
command: bundle exec sidekiq
volumes:
- .:/app:cached
- bundle:/bundle
env_file:
- ./.env
config/initializers/sidekiq.rb
Sidekiq.configure_server do |config|
config.redis = { url: 'redis://redis:6379/12' }
end
Sidekiq.configure_client do |config|
config.redis = { url: 'redis://redis:6379/12' }
end
是的，这是目前公开的硬编码，但我已经尝试过仅使用 ENV 变量的配置，结果完全相同，无论我从哪里获得结果的值都是相同的。现在尝试这样的东西，因为它没有任何区别。
这是我尝试访问 localhost:3000/sidekiq
时的错误

至于使用 ENV 变量，我通常尝试在 .env 文件中设置这样的值
REDIS_URL=redis://redis:6379/12
当我检查 docker ps 时，redis 容器正常。
如果我理解正确，URL redis://redis:6379/12 使用 redis 作为主机名称，对应于我在 docker-[=47 中指定的服务名称=] 并且应该允许容器相互通信。这个文件最初有更多的服务，例如 elasticsearch，它们工作得很好。
我已经尝试了很多不同的设置ps，但我觉得我正在用头撞倒。我错过了什么？
您可能没有将 redis 端口暴露给 sidekiq 服务，请尝试在 docker compose 中暴露它。这可能会奏效。
