Add one element to a list of dictionary ansible / jinja - list

Question

I'm trying to add a element to a list of dictionary.
_gitlab_runner_config:
server:
url: "https://gitlab.mydomain.com"
api_token: "XXXXXXXXXXXXXXXXXX"
registration_token: "YYYYYYYYYYYYYYYY"
global:
listen_address: ":9200"
concurent: 5
check_interval: 15
session_server:
listen_address: "0.0.0.0:8093"
advertise_address: "{{ ansible_fqdn }}:8093"
session_timeout: 600
runners:
- description: "Test runner 1"
token: ""
tags:
- test1
locked: False
active: False
run_untagged: False
access_level: "not_protected"
maximum_timeout: "3600"
executor: "docker"
executor_config:
tls_verify: false
image: "test-image"
pull_policy: "always"
volumes:
cpus:
In another task, i register the token value. Si, i want to set the value of gitlab_runner_config.runners.LIST_INDEX.token
I have try:
- name: "Save runner token"
set_fact:
_gitlab_runner_config: "{{ _gitlab_runner_config|combine({'runners': {runner_index: {'token': _gitlab_server_registered.runner.token}}} ) }}"
but it override the list.

Answer 1

_gitlab_runner_config.runners is a list. This implicates there might be more items on the list. If all items in the list shall be updated with the same token, e.g. mytoken, the play below does the job
vars:
mytoken: token000
tasks:
- set_fact:
config_updated: "{{ {'runners': _gitlab_runner_config.runners|
map('combine', {'token': mytoken})|
list} }}"
- set_fact:
_gitlab_runner_config: "{{ _gitlab_runner_config|
combine(config_updated) }}"
If there might be different tokens for each item of the list the list shall be updated in a loop. For example, given the list of tokens mytokens, the play below
vars:
mytokens:
- {'token': 'token000'}
- {'token': 'token001'}
- {'token': 'token002'}
tasks:
- set_fact:
runners: "{{ runners|default([]) +
[item|combine(mytokens[ansible_loop.index0])] }}"
loop: "{{ _gitlab_runner_config.runners }}"
loop_control:
extended: yes
- set_fact:
config_updated: "{{ {'runners': runners} }}"
- set_fact:
_gitlab_runner_config: "{{ _gitlab_runner_config|
combine(config_updated) }}"
- debug:
var: _gitlab_runner_config
gives

Thanks for your help and answer #vladimir-botka.
But my problem is more complex but, my fault, i didn't give all the detail in my last post.
I have a dict gitlab_runner_config which contain list of runners _gitlab_runner_config.runners. I already loop in this list to register each runner, and i get a token in response (each runner will have a different token). I want to insert this token into teh field token. The whole dict gitlab_runner_config will be used for templating a config file.
The dict:
_gitlab_runner_config:
server:
url: "https://gitlab.mydomain.com"
api_token: "XXXXXXXXXXXXXXXXXX"
registration_token: "YYYYYYYYYYYYYYYY"
global:
listen_address: ":9200"
concurent: 5
check_interval: 15
session_server:
listen_address: "0.0.0.0:8093"
advertise_address: "{{ ansible_fqdn }}:8093"
session_timeout: 600
runners:
- description: "Test runner 1"
token: ""
tags:
- test1
locked: False
active: False
run_untagged: False
access_level: "not_protected"
maximum_timeout: "3600"
executor: "docker"
executor_config:
tls_verify: false
image: "test-image"
pull_policy: "always"
volumes:
cpus:
- description: "Test runner 2"
token: ""
tags:
- test2
locked: False
active: False
run_untagged: False
access_level: "not_protected"
maximum_timeout: "3600"
executor: "docker"
executor_config:
tls_verify: false
image: "test-image"
pull_policy: "always"
volumes:
cpus:
The tasks which register each runenr with a loop:
- name: "Registered runners"
include_tasks: register.yml
loop: "{{ _gitlab_runner_config.runners }}"
loop_control:
index_var: runner_index
register.yml:
- name: "Register runner on gitlab server"
gitlab_runner:
api_url: "{{ _gitlab_runner_config.server.url }}"
api_token: "{{ _gitlab_runner_config.server.api_token }}"
registration_token: "{{ _gitlab_runner_config.server.registration_token }}"
description: "[{{ ansible_fqdn }}] {{ item.description }}"
state: "present"
active: " {{ item.active }}"
tag_list: "{{ item.tags }}"
run_untagged: "{{ item.run_untagged }}"
maximum_timeout: "{{ item.maximum_timeout }}"
access_level: "{{ item.access_level }}"
locked: "{{ item.locked }}"
validate_certs: "no"
register: _gitlab_server_registered
- name: Debug
debug:
msg: "Token to merge for runner id: {{ runner_index }} : {{ gitlab_server_registered.runner.token }}"
