Data node -Using the Default Provided Docker Compose File will not allow port binding on Docker Swarm

[CyberKaizen]

As the title says using the default provided docker-compose.yml on the latest docker swarm version does not allow the port to bind using the GrayLog install instructions. As the container or service never gets into a healthy state due to the pre-flight.

Hi @CyberKaizen, can you provide please some details.

1. Which compose file do you mean exactly?
2. By pre-flight, do you mean provisioning CA in Data Node during the start or smth else?

1. It is the compose file from here: https://github.com/Graylog2/docker-compose/blob/main/open-core/docker-compose.yml

2. It is the part of the pre-flight check in which the user needs to access the GUI in order to do that step.

Swarm networking behavior is a little different from a single-node docker engine host not initialized as a Swarm host.

The problem is that with Docker Swarm, it will not publish the service to the Swarm host port. Because the service is not in a healthy state at the time the user is presented with the message telling them to access it via GUI.

I believe the Dockerfile needs to be modified in such a way that Swarm does not consider the Graylog server (Not DataNode) service to be in an unhealthy state before the user is told to start the pre-flight.
