Sidekiq 作业未在部署到 heroku 的 Rails 应用程序上排队

Question

I have a rails app using sidekiq, sidekiq-status, and sidekiq batching:

gem "sidekiq"
gem "sidekiq-status"
# freemium version vs sidekiq pro https://github.com/breamware/sidekiq-batch
gem "sidekiq-batch"
# slim & sinatra for sidekiq monitoring
gem "sinatra", "2.0.0.beta2", require: nil

Locally when I run sidekiq and redis, the jobs process. When deployed to heroku, the jobs are queued but they do not process.

I am using the Rediscloud and have the env variable REDIS_PROVIDER set to REDISCLOUD_URL and both REDISCLOUD_URL and REDIS_URL set to the generated url from the Rediscloud addon.

Procfile:

high_worker: DB_POOL=$SIDEKIQ_DB_POOL bundle exec sidekiq -c $SIDEKIQ_CONCURRENCY -t 8 -q high
default_worker: DB_POOL=$SIDEKIQ_DB_POOL bundle exec sidekiq -c $SIDEKIQ_CONCURRENCY -t 8 -q default
low_worker: DB_POOL=$SIDEKIQ_DB_POOL bundle exec sidekiq -c $SIDEKIQ_CONCURRENCY -t 8 -q low

When I startup a queue manually on heroku, ie heroku run DB_POOL=10 bundle exec sidekiq -c 10 -t 8 -q low -a {my_app_name} , the queue processes those jobs.

What am I missing in my configuration?

Your Procfile defines process types, but it doesn't make them run.

Each process type can run on zero or more dynos. To change the number of dynos for each process type you can use the heroku ps:scale command . For example, to scale your low_worker process type to one dyno you can do

heroku ps:scale low_worker=1

Running dynos cost money and / or consume free dyno hours, so budget accordingly.

Alternatively, you can have your jobsrun at scheduled times via the Heroku Scheduler . This is less appropriate for tasks that should run continuously, but it's an option.
