ansible version: 2:11.2 jinja version: 3.0.3 python version: 3.6.8 Hello all
I have a peculiar problem with a relatively simple playbook I have written. It basically checks 2 servers to determine which one has more than 1 IP and uses that to set a simp;e fact called "is_leader" for each node. This fact is then to be used to build an in-memory inventory using module add_host to iterate through the servers based on the value of that fact. See below: - name: Get Server Recycling Order hosts: "{{ my_servers | default ('localhost') }}" become: yes become_method: sudo become_user: root tasks: - name: Set Patching Sequence tags: always block: - name: Get IP addresses of eth0 using nmcli command command: nmcli -g ip4.address conn show "System eth0" register: nmcli_output changed_when: false - name: Get nmcli output debug: var: nmcli_output - name: Set is_leader variable based on number of IPs set_fact: is_leader: "{{ (nmcli_output.stdout.split('|') | length) > 1 }}" - name: Display if server is ACTIVE (1) or PASSIVE (0) debug: var: is_leader - name: Debug is_leader value debug: msg: "is_leader value for {{ inventory_hostname }} is {{ is_leader }}" - name: Add standby host add_host: name: "{{ inventory_hostname }}" groups: nodes when: not is_leader - name: Add primary host add_host: name: "{{ inventory_hostname }}" groups: nodes when: is_leader #- name: Execute tasks on servers in a specified order # hosts: nodes # gather_facts: no # serial: 1 # tasks: # - name: Run a command in a specified order # command: echo "Running on {{ inventory_hostname }}" # tags: always The problem is that when this runs, the "is_leader" fact is ignored for when the condition is false and the standby node is not added to the inventory. The relevant extract from the execution is below: TASK [Set is_leader variable based on number of IPs] ************************************************************************************************************************** Tuesday 23 April 2024 19:46:31 +0000 (0:00:00.079) 0:00:16.815 ********* ok: [node-1] => { "ansible_facts": { "is_leader": true }, "changed": false } ok: [node-2] => { "ansible_facts": { "is_leader": false }, "changed": false } TASK [Display if server is ACTIVE (1) or PASSIVE (0)] ************************************************************************************************************************** Tuesday 23 April 2024 19:46:31 +0000 (0:00:00.083) 0:00:16.898 ********* ok: [node-1] => { "is_leader": true } ok: [node-2] => { "is_leader": false } TASK [Debug is_leader value] ************************************************************************************************************************************************** Tuesday 23 April 2024 19:46:31 +0000 (0:00:00.072) 0:00:16.971 ********* ok: [node-1] => {} MSG: is_leader value for node-1 is True ok: [node-2] => {} MSG: is_leader value for node-2 is False TASK [Re-confirm is_leader before adding to group] **************************************************************************************************************************** Tuesday 23 April 2024 19:46:31 +0000 (0:00:00.074) 0:00:17.045 ********* skipping: [node-1] => {} ok: [node-2] => {} MSG: Preparing to add node-2 to stby group based on is_leader = False TASK [Add standby proxysql node] *********************************************************************************************************************************************** Tuesday 23 April 2024 19:46:31 +0000 (0:00:00.088) 0:00:17.134 ********* skipping: [node-1] => { "changed": false, "skip_reason": "Conditional result was False" } TASK [Re-confirm is_leader before adding to group] **************************************************************************************************************************** Tuesday 23 April 2024 19:46:31 +0000 (0:00:00.036) 0:00:17.170 ********* ok: [node-1] => {} MSG: Preparing to add node-1 to prim group based on is_leader = True skipping: [node-2] => {} TASK [Add primary proxysql node] *********************************************************************************************************************************************** Tuesday 23 April 2024 19:46:31 +0000 (0:00:00.059) 0:00:17.230 ********* changed: [node-1] => { "add_host": { "groups": [ "nodes_prim" ], "host_name": "node-1", "host_vars": {} }, "changed": true } PLAY RECAP ********************************************************************************************************************************************************************* localhost : ok=1 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0 node-1 : ok=8 changed=1 unreachable=0 failed=0 skipped=2 rescued=0 ignored=0 node-2 : ok=7 changed=0 unreachable=0 failed=0 skipped=1 rescued=0 ignored=0 I'm not sure what I'm missing regarding this behaviour as it seems like it should simply work?
