Hi, Thanks for the tutorials. I will look further tomorrow. I tried my server, Synology NAS, using container docker; however, I always have an issue with the docker command when sending to my Synology NAS using SSH. Then I tried to add my SSH keys to the profile and bash to the container that I built, but still, I could not push my rails using Kamal I got same error docker command issue. However, when I access my Synology using SSH and do the command docker -v, it is working. It seems there is a missing configuration, or Synology is not allowing Kamal. Any idea, how to use kamal in synology nas? thanks
