Random TCP Port Generator for Ruby
It’s a simple Ruby gem to get a random TCP port.
First, install it:
gem install random-port
Then, use it like this, to reserve a random TCP port:
require 'random-port'
port = RandomPort::Pool.new.acquire
The Pool
guarantees that the port won’t be used again. You can put
the port back to the pool after usage:
RandomPort::Pool.new.acquire do |port|
# Use the TCP port. It will be returned back
# to the pool afterwards.
end
You can do it without the block:
pool = RandomPort::Pool.new
port = pool.acquire
pool.release(port)
You can also use a pre-defined Pool::SINGLETON
singleton:
RandomPort::Pool::SINGLETON.acquire do |port|
# Use it here...
end
The pool is thread-safe by default.
You can configure it to be
not-thread-safe, using optional sync
argument of the constructor.
