# SSHKit # # [SSHKit](https://github.com/capistrano/sshkit) is the SSH toolkit used by Kamal. # # The default settings should be sufficient for most use cases, but # when connecting to a large number of hosts you may need to adjust # SSHKit options # # The options are specified under the sshkit key in the configuration file. sshkit: # Max concurrent starts # # Creating SSH connections concurrently can be an issue when deploying to many servers. # By default Kamal will limit concurrent connection starts to 30 at a time. max_concurrent_starts: 10 # Pool idle timeout # # Kamal sets a long idle timeout of 900 seconds on connections to try to avoid # re-connection storms after an idle period, like building an image or waiting for CI. pool_idle_timeout: 300
