use rest_info to rename things

[grim pasture]

trying to use the rest_info module to input into other tasks to rename things such as nodes and LIFs.

- name: Get info from cluster na_ontap_rest_info: use_rest: always gather_subset: - cluster/nodes fields: - 'name' <<: *login register: ontap_info - debug: msg: "{{ ontap_info.ontap_info}}"

- name: Rename Nodes na_ontap_node: use_rest: always from_name: "{{ ontap_info.ontap_info.records.name }}" name: "{{ node1name }}" <<: *login
This prints the nodename and other things, i cant seem to figure out how to narrow the output down to just the 'name'. when specifying fields it still shows uuid and other items in structure.

fatal: [localhost]: FAILED! => {"changed": false, "msg": "Node not found: {'cluster/nodes': {'records': [{'uuid': '76ca839a-bc22-11ed-a1c9-000c29957a37', 'name': 'cluster0300-01', '_links': {'self': {'href': '/api/cluster/nodes/76ca839a-bc22-11ed-a1c9-000c29957a37'}}}], 'num_records': 1, '_links': {'self': {'href': '/api/cluster/nodes?max_records=1024&fields=name'}}}}"}

I realise this is not a netapp ansible problem, but if anyone can help my format the json output that would be awsome.

I've been wrestling with this myself and this is how I finally solved how to grab the node names:

    netapp.ontap.na_ontap_rest_info:
        gather_subset: "cluster_node_info"
    register: ontap_info

  - name: Extracting name of nodes
    set_fact:
      ontap_nodes: "{{ ontap_info.ontap_info['cluster/nodes'].records | json_query(query) }}"
    vars:
      query: "[*].name"

  - debug:
     msg: "{{ ontap_nodes }}"
     verbosity: 1```

I think it has something to do with Ansible not being able to read JSON so it has to be converted, or something like that.

thanks mate, i had use json_query before and was hoping for a method that didnt require it as its another package the customer will need. but seems like thats the recommended ansible way so lets go with it.

I'd appreciated it very much if you could please help me out on the playbook. Your playbook sounds a great one for me to learn. Or, if you could please post the final version of yours.
`-
name: Practice
hosts: localhost
gather_facts: False
collection:
- netapp.ontap
tasks:
- name: Get cluster node info
netapp.ontap.na_ontap_rest_info:
gather_subset: "cluster_node_info"
hostname: x.x.x.x
username: admin
password: netapp123
register: ontap_info
- name: Extracting name of nodes
https: true
validate_certs: false
set_fact:
ontap_nodes: "{{ ontap_info.ontap_info['cluster/nodes'].records | json_query(query) }}"
vars:
query: "[*].name"

  - debug:
      msg: "{{ ontap_nodes }}"
      verbosity: 1`

Not sure if it is a paste issue but your indentation is wrong, the tasks needs to be in the same column.

[grim pasture]

this issue im seeing with this playbook is that the nodename is passed with [] around it and causing error. think its to do with the [*].name query as if i change to [0] it works but then this will let allow for multiple items. fatal: [localhost]: FAILED! => {"changed": false, "msg": "Node not found: ['oldnodename']"}

using -vvv shows this in more detail "from_name": "['oldnodename']",

[grim pasture]

try this. i stole it from another post in here seems to work well and doesnt use json_query.

` tasks:
- name: Get list of nodes in the cluster
na_ontap_rest_info:
<<: *login
gather_subset:
- cluster/nodes
register: node_list

- name: Rename Nodes
  na_ontap_node:
    use_rest: never
    from_name: "{{ item.name }}"
    name: "{{ node1name }}"
    <<: *login
  loop: "{{ node_list['ontap_info']['cluster/nodes']['records'] }}"`

I am missing something here. But, what is "node1name" here?
TASK [Rename nodes] ****************************************************************************************************************************
fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'node1name' is undefined\n\nThe error appears to be in....

[grim pasture]

items lists within "{{ }}" are variables. in this example the node1name variable is defined in a separete vars files not show in the above example.

@grim pasture Excuse my persistence!

1. Could you please show me the contents of "variables.yml" as defined in my code?
2. What your code should result in? from_name: "{{ item.name }}" should print out old node names, and name: "{{ node1name }}" should simulate new names that we want nodes to be renamed, right?

If you use python_keys: true in the play book it will covert cluster/nodes in to cluster_nodes so you can use do ontap_info.ontap_info.cluster_nodes.records

I was working with someone on a similar problem but with SVM Let me show it here since i think it will probably be helpful

So i have the following playbook with 3 different print statements

` tasks:
- name: Get info
netapp.ontap.na_ontap_rest_info:
use_python_keys: true
use_rest: Always
gather_subset:
- vserver_info
<<: *login
register: results

- name: Print return information from the previous task
  ansible.builtin.debug:
    var: results

- name: Get info
  netapp.ontap.na_ontap_rest_info:
    use_python_keys: true
    parameters:
      uuid:
        5ab678b1-d3f2-11ed-8f2b-005056b3357c
    use_rest: Always
    gather_subset:
      - vserver_info
    <<: *login
  register: results2

- name: Print the first name on the list
  ansible.builtin.debug:
    var: results2.ontap_info.svm_svms.records[0].name

- name: Print all names on a list
  ansible.builtin.debug:
    msg: "Hest are the names: {{ item.name }}"
  with_items: "{{results.ontap_info.svm_svms.records}}"`

The first one is going to return everything

ok: [localhost] => { "results": { "changed": false, "failed": false, "ontap_info": { "svm_svms": { "_links": { "self": { "href": "/api/svm/svms?max_records=1024&fields=" } }, "num_records": 4, "records": [ { "_links": { "self": { "href": "/api/svm/svms/5a9021d3-d57e-11ed-8f2b-005056b3357c" } }, "name": "terraform", "uuid": "5a9021d3-d57e-11ed-8f2b-005056b3357c" }, { "_links": { "self": { "href": "/api/svm/svms/5ab678b1-d3f2-11ed-8f2b-005056b3357c" } }, "name": "nfs-test", "uuid": "5ab678b1-d3f2-11ed-8f2b-005056b3357c" }, { "_links": { "self": { "href": "/api/svm/svms/7a7eca52-92d0-11ed-8f2b-005056b3357c" } }, "name": "ansibleSVM", "uuid": "7a7eca52-92d0-11ed-8f2b-005056b3357c" } ] } } } }

The second one since i know only had 1 result i've hard coded it to return just the name of the first thing in records.

TASK [Print the first name on the list] ********************************************************************** ok: [localhost] => { "results2.ontap_info.svm_svms.records[0].name": "nfs-test" }

The last one i'm doing a for loop to get the name of all 4 svms

TASK [Print all names on a list] ***************************************************************************** ok: [localhost] => (item={'uuid': '5a9021d3-d57e-11ed-8f2b-005056b3357c', 'name': 'terraform', '_links': {'self': {'href': '/api/svm/svms/5a9021d3-d57e-11ed-8f2b-005056b3357c'}}}) => { "msg": "Hest are the names: terraform" } ok: [localhost] => (item={'uuid': '5ab678b1-d3f2-11ed-8f2b-005056b3357c', 'name': 'nfs-test', '_links': {'self': {'href': '/api/svm/svms/5ab678b1-d3f2-11ed-8f2b-005056b3357c'}}}) => { "msg": "Hest are the names: nfs-test" } ok: [localhost] => (item={'uuid': '7a7eca52-92d0-11ed-8f2b-005056b3357c', 'name': 'ansibleSVM', '_links': {'self': {'href': '/api/svm/svms/7a7eca52-92d0-11ed-8f2b-005056b3357c'}}}) => { "msg": "Hest are the names: ansibleSVM" } ok: [localhost] => (item={'uuid': '84770f95-92d0-11ed-8f2b-005056b3357c', 'name': 'ansibleSVM_cifs', '_links': {'self': {'href': '/api/svm/svms/84770f95-92d0-11ed-8f2b-005056b3357c'}}}) => { "msg": "Hest are the names: ansibleSVM_cifs" }
