Question

Rails not writing to production logs

I followed the tutorial (https://www.digitalocean.com/community/articles/how-to-use-the-dokku-one-click-digitalocean-image-to-run-a-ruby-on-rails-app) to get my rails app up and running with dokku.

When I do: dokku logs APP_NAME, all that I see are three lines corresponding to the server starting, so my logs aren’t being written to properly. How can I debug this? Common reasons my app isn’t writing production logs?

Thanks

You have to redirect logs to Stdout, so edit config/environments/production.rb properly:

logger           = ActiveSupport::Logger.new(STDOUT)
logger.formatter = config.log_formatter
config.logger    = ActiveSupport::TaggedLogging.new(logger)

Hint: maybe you need the Lograge gem too.

Try doing docker ps to get a list of your containers. Find your container under the container ID column. After that do docker logs <container-id>.

Has anyone found a solution to this problem? I’m having the exact same issue.
