How to set a specific environment variable for each node in docker swarm?

Question

Docker

For the docker service create command , you can use templates for the --env field, but the Labels variable for Node is not available there, for example:

docker service create --env SOME_ENV="{{.Node.Labels.SOME_NODE_LABEL_VALUE}}"

Maybe there is some correct way for this, ie. for each node, set labels in advance, and then use them when starting the task in docker swarm.

Answer 1

Docker Swarm does not have this functionality.
