It seems I’m getting a fairly typical nilclass error. However, the way this code is run in production (WITHOUT DOCKER) is fine and sidekiq jobs fire off without any issues. However, sidekiq doesn’t like my app in development mode with docker. I am new to docker so I don’t have a lot of expertise in how it runs. I would like to know how to get sidekiq to run in development mode with docker and be able to fire off jobs.
I have my sidekiq.yml and sidekiq_scheduler.yml file inside my /config folder of my rails app and my sidekiq.rb and scheduler.rb file inside of /config/initializers. Again, the structure of sidekiq runs fine without docker in production mode. Anyone that can point me in the proper direction of how to deal with the issue I’m having would be awesome. SO is kind of silent on the question so far.
Here is my docker-compose.yml file if that might yield any additional info and just ask if you need anything else:
Could you please try your use case without any host mounts (volumes in the compose file)?
This will help us narrow down the cause of the problem. Also, please feel free to open an issue on the tracker at https://github.com/docker/for-mac/issues if you can provide a full reproduction of the issue (that is, all of the configuration files needed to show the issue). For the issue report, it would be very helpful to try to minimize the number of factors involved in reproducing the issue.
I’ve removed both volume sections from the docker-compose file and rebuilt and then started up my app. I’ve included the full output. It seems to be exactly the same as what it was before.
