how to use

[asobeeh]

sorry about that, but I am new with ansible and I want to call this playbook in my playbook as a role.
and I want to know how to use this playbook, were to define the hosts, what should I do,
can you please define a how-to, to explain in steps how to run it and where is the values should I change and where to change,
and for the replica how to enable it, and how to make it a single deployment or replica deployment with attribute
I know that it may be a clear thing but sorry for that.

can you please help me with this

I tried the below to call it a role and pass the var from my playbook but it give me the below error

- hosts: all
  tasks:
    - name: "get facts about ip addresses"
      setup:
        filter: ansible_default_ipv4
    - name: "set mongodb_replication_params variable"
      set_fact:
        mongodb_replication_params:
          - host_name: "{{ hostvars[item]['ansible_default_ipv4']['address'] }}"
            host_type: "{{ replica if 'mongodb-replica' in group_names else arbiter }}"
      with_items:
        - "{{ groups['mongodb-replica'] }}"
        - "{{ groups['mongodb-arbiter'] }}"
      debug: msg="echo"
  roles:
    - ansible-role-mongodb

    ERROR! conflicting action statements: set_fact, debug

The error appears to be in '/root/newmongo.yaml': line 7, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

        filter: ansible_default_ipv4
    - name: "set mongodb_replication_params variable"
      ^ here

I tried to use the below also,

- hosts: all
  tasks:
    - name: determine which ethernet interface holds the ip we want to use in mongo
      set_fact:
        eth_interface: "ansible_eth1"
      when: stage == "development"
    - name: determine which ethernet interface holds the ip we want to use in mongo
      set_fact:
        eth_interface: "ansible_eth0"
      when: stage != "development"
    - name: determine who is the master
      set_fact:
        mongodb_masternode: "{{ groups['mongodb-datastore'][0] }}"
    - name: determine the master ip
      set_fact:
        mongodb_masternode_ip: "{{ hostvars[mongodb_masternode][eth_interface]['ipv4']['address'] }}"
    - name: echo mongodb_masternode ip
      debug: msg={{ mongodb_masternode_ip }}
    - name: determine own ip
      set_fact:
        own_ip: "{{ ansible_eth1.ipv4.address }}"
      when: stage == "development"
    - name: determine own ip
      set_fact:
        own_ip: "{{ ansible_eth0.ipv4.address }}"
      when: stage != "development"
    - name: echo my ip
      debug: msg={{ own_ip }}
    - name: test if this machine is not the master
      set_fact:
        mongodb_master: false
      when: mongodb_masternode_ip != own_ip
    - name: test if this machine is the master
      set_fact:
        mongodb_master: true
      when: mongodb_masternode_ip == own_ip

    - name: Build replication json config
      set_fact:
        replication: "{{ lookup('template', 'mongodb_replication_params.j2') }}"
        # note that we build a _string_ here containing json, not a json object
      vars:
        hosts: "{{ groups['mongodb-datastore'] + groups['mongodb-arbiter'] }}"
    - name: echo replication
      debug: msg={{ replication }}

    - name: Convert replication json to an ansible variable mongodb_replication_params
      set_fact:
        mongodb_replication_params: "{{ replication|from_json }}"

    - name: echo mongodb_replication_params
      debug: msg={{ mongodb_replication_params }}
  roles:
    - ansible-role-mongodb

it gives me the below error

TASK [determine which ethernet interface holds the ip we want to use in mongo] *******************************************************
fatal: [192.168.1.46]: FAILED! => {"msg": "The conditional check 'stage == \"development\"' failed.

Hi, I was first not able to get replication working.
If you look closer, you will see it is a json object in a list

Check the example below which is working for ALMA8 with a 3 node cluster: test01-03

- hosts: mongo
  gather_facts: yes
  vars:
    mongodb_net_bindip: "127.0.0.1,{{ ansible_default_ipv4.address }}"
    mongodb_storage_dbpath: /var/lib/mongo

    mongodb_replication_replset: rs0

    mongodb_user_admin_name: siteUserAdmin
    mongodb_user_admin_password: xxxxxx

    mongodb_root_admin_name: siteRootAdmin
    mongodb_root_admin_password: xxxxxx

    mongodb_root_backup_name: backupuser
    mongodb_root_backup_password: xxxxxx

    mongodb_security_authorization: "enabled"
    mongodb_users:
      - {
        name: graylog,
        password: xxxxxx,
        roles: readWrite,
        database: admin
    }
      - {
        name: graylog,
        password: xxxxxx,
        roles: readWrite,
        database: graylog
    }

    mongodb_login_host: test01

    mongodb_replication_params:
      - {
          host_name: test01,
          host_port: "{{ mongodb_net_port }}",
          host_type: replica,
        }
      - {
          host_name: test02,
          host_port: "{{ mongodb_net_port }}",
          host_type: replica,
        }
      - {
          host_name: test03,
          host_port: "{{ mongodb_net_port }}",
          host_type: replica,
        }
