   prom_cpu_limit: 1
   prom_ram_request: 512Mi
   prom_ram_limit: 1Gi
   #Grafana

Example Playbook

Playbook example:

- hosts: "{{ project_list }}"
  become: no
  gather_facts: no
  vars_files:
    - vars/clusters.yaml
  environment:
    K8S_AUTH_HOST: "{{ clusters[cluster_name]['k8s_auth_host'] }}"
    K8S_AUTH_API_KEY: "{{ clusters[cluster_name]['k8s_auth_api_key'] }}"
  tasks:
    - include_role:
        name: gap
      vars:
        project_name: "{{ inventory_hostname }}"

Example above for usage with particulary cluster inventory, for simpler enough define variable {{ project_name }} , something like this:

    - include_role:
        name: gap
      vars:
        project_name: "exist_project_for_gap"
