The Sidekiq CNB sets the start command for a given ruby application that runs on a sidekiq server.
This CNB writes a start command, so there's currently no scenario we can imagine that you would need to require it as dependency. If a user likes to include some other functionality, it can be done independent of the Sidekiq CNB without requiring a dependency of it.
To package this buildpack for consumption:
$ ./scripts/package.sh
This builds the buildpack's source using GOOS=linux by default. You can supply another value as the first argument to package.sh.
There are no extra configurations for this buildpack based on buildpack.yml.
