# Start Puma with next command:

# uncomment and customize to run in non-root path
# ENV['RAILS_RELATIVE_URL_ROOT'] = "/suburl"

# The directory to operate out of.
#
# Make it pick up the current path from capistrano deploy.

# Pick it up from the app environment.

# Daemonize the server into the background. Highly suggest that
# this be combined with “pidfile” and “stdout_redirect”.
#
# The default is “false”.

daemonize true

# Store the pid of the server in the file at “path”.

# Use “path” as the file to store the server info state. This is
# used by “pumactl” to query and control the server.
#
state_path "#{application_path}/shared/tmp/pids/puma.state"

# Redirect STDOUT and STDERR to files specified. The 3rd parameter
# (“append”) specifies whether the output is appended, the default is
# “false”.

# Disable request logging.
#
# The default is “false”.

# Configure “min” to be the minimum number of threads to use to answer
# requests and “max” the maximum.
#
# The default is “0, 16”.
#
# threads 0, 16

# Bind the server to “url”. “tcp://”, “unix://” and “ssl://” are the only
# accepted protocols.
#
# The default is “tcp://0.0.0.0:9292”.

# Command to use to restart puma. This should be just how to
# load puma itself (ie. 'ruby -Ilib bin/puma'), not the arguments
# to puma, as those are the same as the original process.

# === Cluster mode ===

# How many worker processes to run.

# The default is “0”.

# the app.

# === Puma control rack application ===

# Start the puma control rack application on “url”. This application can
# be communicated with to control the main server. Additionally, you can
# provide an authentication token, so all requests to the control server
# will need to include that token as a query parameter. This allows for
# simple authentication.
#
# Check out https://github.com/puma/puma/blob/master/lib/puma/app/status.rb
# to see what the app has available.
