Error with traefik ´main.yml line 34

[R-Hammer]

Hi, i’m trying to run this without glusterFS and HA-Proxy and with ssh key on cloud servers.
Goal is to run a monogdb replica set and some other services.

For that I changed the host-file to this:

[swarm_managers]
First_ip
secound_ip
third_ip

[all:vars]
ansible_connection=ssh
ansible_user=my_user_with_sodo
device2_hdd_dev=/dev/sdb

And main.yml in roles/docker/ to this:

---
- import_tasks: docker.yml
# - import_tasks: plugins.yml

The error I get, when running

ansible-playbook --inventory-file=hosts-vagrant playbooks/install.yml

is:

[WARNING]: Could not match supplied host pattern, ignoring: swarm_workers

 [WARNING]: Could not match supplied host pattern, ignoring: gluster_nodes

ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in '/git/server-setup-ansible/playbooks/roles/traefik/tasks/main.yml': line 34, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


- name: Deploy stack from a compose file (on first swarm node)
  ^ here

What have I done wrong?
Any help would be great!
