Rails 5.2, Docker Compose, Sidekiq, Redis.
这是 docker 撰写文件:
version: '3.6'
services:
redis:
image: 'redis:4.0-alpine'
command: redis-server
ports:
- '6379:6379'
volumes:
- 'redis:/data'
sidekiq:
depends_on:
- 'redis'
build: .
command: bundle exec sidekiq -C config/sidekiq.yml
volumes:
- './:/app'
env_file:
- '.env'
api:
build: .
volumes:
- './:/app'
working_dir: /app
command: puma
ports:
- 3000:3000
depends_on:
- db
- redis
environment:
DATABASE_URL: postgres://postgres@db
db:
image: postgres:10.3-alpine
volumes:
redis:
postgres:
似乎sidekiq找不到我的Rails应用程序。
如果我将 sidekiq 更改为这样开始:
command: bundle exec sidekiq -C config/sidekiq.yml -r /app
然后我收到此错误:
Spring 无法找到您的 config/application.rb 文件。你 在/API 上检测到项目根目录,因此 Spring 查找 /api/config/application.rb,但它不存在。您可以配置 通过设置 Spring.application_root 来获取应用程序的根目录 config/spring.rb.
如果我将working_dir
设置添加到 sidekiq:
sidekiq:
depends_on:
- 'redis'
build: .
command: bundle exec sidekiq -C config/sidekiq.yml
volumes:
- './:/app'
env_file:
- '.env'
working_dir:
- '/app'
然后我收到此错误:
2019-05-27T20:27:59.770Z 1 TID-gr1e0d7n5 INFO: Booting Sidekiq 5.1.1 with redis options {:url=>"redis://redis:6379/0", :id=>"Sidekiq-server-PID-1"}
sidekiq_1 | could not connect to server: No such file or directory
sidekiq_1 | Is the server running locally and accepting
sidekiq_1 | connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
那么如何让 sidekiq 在其容器中正确启动呢?
我已经看到了这些答案,它们相似但不是这个特定的错误:
问题1
问题2
问题3
问题4
似乎 sidekiq 找不到 Rails 应用程序,该应用程序是通过添加"work-dir"设置来修复的,然后它找不到 postgres,所以我不得不添加环境设置以指向 postgres。
最终的撰写文件是:
