Remote builder does not pass the username to SSHKit properly

[hoblin]

I have the following build config:

builder:
  remote:
    arch: arm64
    host: ssh://username@192.168.0.111
  cache:
    type: gha

When i run build it ignores the provided username and asks for a password for ubuntu user

  INFO [35c09382] Running /usr/bin/env true on 192.168.0.111
ubuntu@192.168.0.111's password:

I found that here username is passed as an option

kamal/lib/kamal/cli/build.rb

Lines 114 to 122 in 457f06d

	def connect_to_remote_host(remote_host)
	remote_uri = URI.parse(remote_host)
	if remote_uri.scheme == "ssh"
	options = { user: remote_uri.user, port: remote_uri.port }.compact
	on(remote_uri.host, options) do
	execute "true"
	end
	end
	end

But it seems like SSHKit expects it as a part of the host name. I was able to connect successfully with the following change:

        on("#{remote_uri.user}@#{remote_uri.host}", options) do

I just ran into this issue as well. My remote builder uses the ubuntu user, but Kamal is attempting to connect to the server using root (I am guessing it's getting that user from the deployment configuration).

Here are the relevant bits of configuration files and logs.

# deploy.yml
builder:
  remote:
    arch: amd64
    host: ssh://ubuntu@remote-server

Any update on this, I'm having the same issue as well. Need to use ubuntu username instead of root
