And you can then use it in the Dockerfile: 

# Assuming we're inside the original current_user method
# Get the current method object
current_
method = method(__method__)

# Define the new method
new_method = proc do |*args|
  puts "Entering modified current_user method"
  result = current_method.call(*args)
  puts "current_user result: #{result. inspect}"
  # debugger
  result
end
# Replace the method
self.class.send :define_method,__method__, new_method)
self.class.send :define_method, "old_#{__method__}", current _method)

# Restore the old method
old_method = method ("old_#{__method__}")
self.class.send(:define_method,__method__, old_method)
self.class.send(:undef_method, "old_#{__method

# Call the new method to continue execution
new_method.call
