[Bug]: Docker Swarm - Future warning (--detach)

[XenonR]

Error Message and Logs

Manager

Since --detach=false was not specified, tasks will be created in the background.
In a future release, --detach=false will become the default.
failed to update service coolify-proxy_traefik: Error response from daemon: rpc error: code = Unknown desc = update out of sequence

Worker

Since --detach=false was not specified, tasks will be created in the background.
In a future release, --detach=false will become the default.
this node is not a swarm manager. Use "docker swarm init" or "docker swarm join" to connect this node to swarm and try again

Steps to Reproduce

1. Encountered with Docker version 27.3.1, build ce12230
2. Docker Swarm was already setup.
3. Add a Swam Manager or Swarm Worker in Coolify.
4. Validate Server & Install.

Example Repository URL

No response

Coolify Version

v4.0.0-beta.360

Are you using Coolify Cloud?

No (self-hosted)

Operating System and Version (self-hosted)

Debian GNU/Linux 12 (bookworm)

Additional Information

The same error occurs when trying to deploy something.

What is the idea or deployment goal?

coolify/app/Actions/Proxy/StartProxy.php

Line 31 in 5d62a46

if ($server->isSwarm()) {

From the docker command alone I would assume we need to change if ($server->isSwarm()) { to if ($server->isSwarmManager()) {

Related to #4130
After correcting this issue we encounter traefik:v2 configuration but want to use traefik:v3.1

[XenonR]

After addressing #4146 and #4130 the proxy is able to start at a docker manager, but still fails on a worker with:

On worker nodes it should not be required to deploy the proxy. As long as the ingress routing mesh is used the proxy of the manager will also be reachable from the workers.

I need someone who explains the desired design to continue.

Hi, @andrasbacsai, @peaklabs-dev

I saw that @XenonR suggested the change to fix on his comment and didn't open a PR for that.

Can I open a PR with his change? I didn't test yet, but the changes looks good so far.

PR created #4938

It might be worth mentioning that --detach flag is not supported until v26 I believe, and the coolify docs in their swarm setup example mentioned version 24 which will not work https://coolify.io/docs/knowledge-base/docker/swarm/.
