Cluster deployment fails in configure_dmc.yml #214
Description
The task Configure systems as search peers to be monitored except indexers is defined thus:-
# Add all hosts to the DMC except indexer cluster hosts as per the docs - name: Configure systems as search peers to be monitored except indexers ansible.builtin.shell: | {{ splunk_home }}/bin/splunk add search-server https://{{ item }}:{{ splunkd_port }} -auth "{{ splunk_auth }}" -remoteUsername "{{ splunk_admin_username }}" -remotePassword "{{ splunk_admin_password }}" loop: "{{ query('inventory_hostnames', 'all:!indexer') }}" become: true become_user: "{{ splunk_nix_user }}" no_log: trueWhen I call the deployment task configure_dmc.yml it fails:-

Peer with server name splunk-mgr-1-staging.example conflicts with this server's name. It appears that the dmc host is trying to add itself, causing the play to fail, but I am not sure what the resolution should be.
In the ansible hosts inventory, I have the following:-
[clustermanager] splunk-mgr-1-staging.example [deploymentserver] splunk-mgr-1-staging.example [dmc] splunk-mgr-1-staging.example [indexer] splunk-idx-[1:3]-staging.example [licensemaster] splunk-mgr-1-staging.example [search] splunk-sh-[1:3]-staging.example [shc] splunk-sh-[1:3]-staging.example [shcaptain] splunk-sh-1-staging.example [shdeployer] splunk-mgr-1-stagingIn main.yml I have:-
- hosts: dmc become: true vars: deployment_task: "configure_dmc.yml" roles: - role: splunk
