Multiple labels with the same key for services

[C4ArtZ]

I'm trying to grant two Roles access to a server based on its label: "dev" and "infrastructure".

I tried doing that with the labels group:dev and group:infrastructure.
I can add multiple labels with the same key to the roles like this:

node_labels:
  group:
  - dev
  - infrastructure

But I can't do the same on the service itself, as the service always fails to start.
This is what I tried (I know the last one is invalid YAML):

labels:
  group: infrastructure, dev

labels
  group: ["infrastructure", "dev"]

labels:
  group:
  - infrastructure
  - dev

labels:
  group: infrastructure
  group: dev

Is there something I'm missing or is there a better approach to this?

Labels are key:value pairs, so it's not possible to set a list of values on a node.

The way to do this would be to modify your role:

node_labels:
  env:
  - dev
  group:
  - infrastructure

and then change the labels on your node:

labels:
  env: dev
  group: infrastructure
