[Feature Request] Add support for Docker Swarm

[ghost]

Feature request

Is your feature request related to a problem? Please describe. Yes, it is, and if I want to use a Docker Compose file in the Swarm cluster, then I would need to heavily edit it.

Describe the solution you'd like Adding another dialog box that'll ask you if you want to use the Compose file with Swarm.

Describe alternatives you've considered Switching to K3s

Additional context https://dockerswarm.rocks

I don't know a lot about swarm. Could you provide some examples of what needs to be changed in the current output of the docker-compose.yml file generated by DS in order to be usable with swarm?

• You have to specify constraints
• You also have to create networks manually
• It doesn't have persistent storage, but there are plenty of Ansible playbooks here on this site
• You have to use services like Traefik to actually get to your services Here are some another resources that I found:

I think swarm might be a bit out of scope for the goals of this project. DockSTARTer is really meant to be a simple way to get things up and running with a basic setup. It's mostly aimed at self hosting home server setups. I understand swarm can be used in that context as well, but it requires a bit more careful and deliberate setup. The idea with DS is it should be just as easy to run an app in docker as it is to install it via a package manager like apt-get.

I appreciate the info, and I would advise that if you have interest in both DS and swarm, you could potentially use a compose override file to add in the things you want, or take the compose file generated by DS and modify it to your liking and maintain it manually without rerunning DS.
