Finally fixed it !

It was a networking issue, as pointed out in this issue.

The working stack:

version: '3.5'
services:
  crate:
    image: crate:latest
    ports:
      - "4200:4200"
    environment:
      SLOT: "{{.Task.Slot}}"
    volumes:
      - crate-data:/data
    hostname: "crate-{{.Task.Slot}}"
    command: >
      crate
      -Ccluster.name=swarm
      -Cnode.name=crate-$${SLOT}
      -Cnetwork.publish_host=_eth0_
      -Cdiscovery.type='zen'
      -Cdiscovery.seed_hosts=tasks.crate
      -Ccluster.initial_master_nodes=crate-1
    deploy:
      replicas: 3
volumes:
  crate-data:
    name: 'crate-data-{{.Task.Slot}}'
