Create string from list

[Nico]

Hi there,

I simply cannot figure out how to create a string from a list.

What output I want in a variable: 

"{{10.0.0.1:8080,10.0.0.2:8080}}"

I am retrieving a dynamic list of private IPs from Azure Scaleset.

tasks:

  - name: Connect

    command: az account set -s {{ subscription_id }}

  

  - name: Get private IPs

    command: az vmss nic list --resource-group {{ customer_group }} --vmss-name {{ customer }}-vmss

    register: result

  

  - name: Filter result

    set_fact:

      ip_list: "{{ result.stdout | from_json | json_query('[*].ipConfigurations[*].privateIpAddress') }}"

 
  - set_fact: 

      foo: "{{ item }}:8080"

    with_items: "{{ ip_list }}"

  

  - debug: var=foo

Output so far:

PLAY [localhost] ********************************************************************************************************************

TASK [set_fact] *********************************************************************************************************************

ok: [localhost]

TASK [Connect] **********************************************************************************************************************

changed: [localhost]

TASK [Get private IPs] **************************************************************************************************************

changed: [localhost]

TASK [Filter result] ****************************************************************************************************************

ok: [localhost]

TASK [set_fact] *********************************************************************************************************************

ok: [localhost] => (item=10.1.1.7)

ok: [localhost] => (item=10.1.1.4)

ok: [localhost] => (item=10.1.1.5)

TASK [debug] ************************************************************************************************************************

ok: [localhost] => {

    "foo": "10.1.1.5:8080"

}

I need to create a loop that puts the list into a string.

  - set_fact: 

      foo: "{{ item }}:8080"

    with_items: "{{ ip_list }}"

Does anybody know how to do this?

- set_fact:
foo: '{% for i in ip %}{{ i }}:8080{% if not loop.last %},{% endif
%}{% endfor %}'

It should be {% for i in ip_list %}

Hi Kai,

Thank you so much. I would never have figured that out. The result is however still a bit off:

TASK [debug] ************************************************************************************************************************

ok: [localhost] => {

    "foo": "[u'10.1.1.7']:8080,[u'10.1.1.4']:8080,[u'10.1.1.5']:8080"

}

There is noting wrong with the output, but with the input.
Looks like you ip_list is a list in a list or does contain more that
just the IPs.

What does

- debug: var=ip_list

say?

Result:

TASK [debug] ********************************************************************************************************************************************************

ok: [localhost] => {

    "ip_list": [

        [

            "10.1.1.7"

        ], 

        [

            "10.1.1.4"

        ], 

        [

            "10.1.1.5"

        ]

    ]

}

You have a list in a list, you need to fix your set_fact ip_list to just
create a list.

If that is not an option this will also work for foo at least.

foo: '{% for i in ip %}{{ i.0 }}:8080{% if not loop.last %},{% endif

AWESOME!!!!!

The last line worked perfectly. Many many thanks Kai!
