I'm having trouble verifying the value of a json file on a remote server. I have to overwrite the file once on the remote machine from the template (j2). After that, I start a service that writes additional values to this file.
But when restarting ansible-playbook, this file is overwritten because it differs from the template. Before starting the task of writing a file from a template, I want to check the file for unique values.
For testing on a local machine, I do this and everything works:
- name: Check file
hosts: localhost
vars:
config: "{{ lookup('file','config.json') | from_json }}"
tasks:
- name: Check info
set_fact:
info: "{{ config.Settings.TimeStartUP }}"
- name: Print info
debug:
var: info
- name: Create directory
when: interfaces | length != 0
ansible.builtin.file:
...
But when I try to do the same in a task on a remote machine, for some reason ansible is looking for a file on the local machine
all.yml
---
config_file: "{{ lookup('file','/opt/my_project/config.json') | from_json }}"
site.yml
---
- name: Install My_project
hosts: server
tasks:
- name: Checking if a value exists
set_fact:
info: "{{ config_file.Settings.TimeStartUP }}"
- name: Print info
debug:
var: info
Error:
fatal: [server]: FAILED! => {"msg": "An unhandled exception occurred while templating '{{ lookup('file','/opt/my_project/config.json') | from_json }}'. Error was a <class 'ansible.errors.AnsibleError'>, original message: An unhandled exception occurred while running the lookup plugin 'file'. Error was a <class 'ansible.errors.AnsibleError'>, original message: could not locate file in lookup: /opt/my_project/config.json. could not locate file in lookup: /opt/my_project/config.json"}
Please tell me how to correctly check the key value in a JSON file on a remote server?
fetch the files from the remote hosts first. For example, given the files below for testing
shell> ssh admin#test_11 cat /tmp/config.json
{"Settings": {"TimeStartUP": "today"}}
shell> ssh admin#test_12 cat /tmp/config.json
{"Settings": {"TimeStartUP": "yesterday"}}
The playbook below
- hosts: test_11,test_12
gather_facts: false
tasks:
- file:
state: directory
path: "{{ playbook_dir }}/configs"
delegate_to: localhost
run_once: true
- fetch:
src: /tmp/config.json
dest: "{{ playbook_dir }}/configs"
- include_vars:
file: "{{ config_path }}"
name: config
vars:
config_path: "{{ playbook_dir }}/configs/{{ inventory_hostname }}/tmp/config.json"
- debug:
var: config.Settings.TimeStartUP
will create the directory configs in playbook_dir on the controller and will fetch the files from the remote hosts into this directory. See the parameter dest on how the path will be created
shell> cat configs/test_11/tmp/config.json
{"Settings": {"TimeStartUP": "today"}}
shell> cat configs/test_12/tmp/config.json
{"Settings": {"TimeStartUP": "yesterday"}}
Then include_vars and store the dictionary into the variable config
ok: [test_11] =>
config.Settings.TimeStartUP: today
ok: [test_12] =>
config.Settings.TimeStartUP: yesterday

With this playbook I am able to see the wordpress landing page when I open 'localhost:80/' on my Linux machine. However I am unable to get to the wordpress dashboard. I run the playbook like so: ansible-playbook -i inventory SetupWordpress.yaml
To save time, you may use my github repo:
git clone -b WIP git#github.com:redbilledpanda/DevOpsScripts.git
cd DevOpsScripts && ansible-playbook -i inventory SetupWordpress.yaml
After the playbook completes, I go to http://localhost:80 and I am presented with the installer:
I fill in the details:
Apparently, it succeeds:
When I try logging in, I don't see the dashboard. Instead, I never go past the login screen (it doesn't say incorrect credentials or anything though):
I am at a loss as to what am I doing wrong. Keen to hear from you folks.
UPDATE1: If I skip the part where I generate the wordpress 'salts'/keys it works. I can see the dashboard etc. With these salts however, it just won't get to the wordpress admin dashboard.
Using a minimal sample config file wpconfig.file
<?php
/**

* ...
* Authentication unique keys and salts.
*
* Change these to different unique phrases! You can generate these using
* the {#link https://api.wordpress.org/secret-key/1.1/salt/ WordPress.org secret-key service}.

Summary
Your current question and description seems not to be focused on the necessary part but on everything not so related around
On Ansible tasks I am not able to (re-)produce an issue
The part deals with configuration for a 3rd party web service or PHP only
According this it seems not to be related to Ansible at all
The problem domain seems to be Wordpress and PHP setup and configuration only, namely the config file
For further troubleshooting you may try to template module – Template a file out to a target host, the config file including keys generated define('AUTH_KEY', '{{ lookup('password', '/dev/null chars=ascii_letters length=64') }}');
Check with Browser in Incognito Mode because of invalidated cookies
Therefore it is also not about programming at all
An other site on Stack like serverfault.com, superuser.com, devops.staexchange.com or wordpress.stackexchange.com might fit better for your question
-regenerate the security keys
-Make sure the keys are entered correctly in the wp-config file of your WordPress installation.
I'm trying to copy a json file from my localhost to remote hosts, and use the json "version" key value as a parameter in the destination file name.
JSON:
{"name": "test", "version": 3}
YML:
---
- name: Get json file version
hosts: locahost
become: true
tasks:
- name: Register licenses file
command: "cat conf/licenses.json"
register: result
- name: Save the json data
set_fact:
jsondata: "{{ result.stdout | from_json }}"
- name: Save licenses file version
set_fact:
file_version: "{{ jsondata | json_query(jmesquery) }}"
vars:
jmesquery: 'version'
- name: Deploy Licenses File
hosts: hosts
become: true
tasks:
- name: Copy licenses file
copy:
src: "conf/licenses.json"
dest: "/tmp/licenses_{{ file_version }}.json"
When I run the playbook above, the Deploy Licenses File key doesn't find the file_version fact, even though I can see it is successfully saved in the Get json file version key.
Set file_version fact:
ok: [localhost] => {
"ansible_facts": {
"file_version": "1"
},
"changed": false
}
Error:
The task includes an option with an undefined variable. The error was: 'file_version' is undefined
I think the facts are saved on the given host granularity and are not global facts per playbook initiation.
My current workaround is to combine the keys to a single task and then it works correctly, but I prefer to get the version once instead of repeating it for each remote host.
To access facts of another host, you can always use the hostvars special variable.
So, in your case:
dest: "/tmp/licenses_{{ hostvars.localhost.file_version }}.json"
Now, you actually do not need that level of complication with two plays and could well do:
- name: Deploy Licenses File
hosts: hosts
become: true
tasks:
- name: Copy licenses file
copy:
src: "{{ _licence_file }}"
dest: "/tmp/licenses_{{ file_version }}.json"
vars:
_licence_file: conf/licenses.json
file_version: >-
{{ (lookup('file', _licence_file) | from_json).version }}
The first play runs at localhost only. Therefore the variables declared in the first play are available to localhost only. This is the reason that the variables are not available to host in the second play
The error was: 'file_version' is undefined
Run once the tasks in a block of the first play at all hosts. This way the variables will be available to all hosts in the second play. For example, the simplified playbook below does the job
- hosts: all
tasks:
- block:
- include_vars:
file: licenses.json
name: jsondata
- set_fact:
file_version: "{{ jsondata.version }}"
run_once: true
- hosts: hosts
tasks:
- copy:
src: licenses.json
dest: "/tmp/licenses_{{ file_version }}.json"
Created file at the remote host
shell> ssh admin#test_11 cat /tmp/licenses_3.json
{"name": "test", "version": 3}
The code can be further simplified. The single play below does the job as well
- hosts: hosts
tasks:
- include_vars:
file: licenses.json
name: jsondata
run_once: true
- copy:
src: licenses.json
dest: "/tmp/licenses_{{ jsondata.version }}.json"
I'm facing the issue with ansible playbook, I want to collect the info about all servers to a single file. Simly speaking I need gather info from all servers specified under hosts file.
Here is my .yml file:
---
- hosts: idrac
connection: local
name: Get system inventory
gather_facts: False
collections:
- dellemc.openmanage
tasks:
- name: Get system inventory
dellemc_get_system_inventory:
idrac_ip: "{{ idrac_ip }}"
idrac_user: "root"
idrac_password: "root"
register: result
- name: Copy results locally to output file
copy:
content: "{{ result }}"
dest: "./output/system_inventory_output.json"
delegate_to: localhost
But the problem is that I check output file, it contains json data only from one server.
I've been browsing the Net but till now did not find any working solution for that...
Any idea how to achieve that?
Thanks!
Create the output file in a second play, and iterate over all the hosts using a template. Something like this:
---
- hosts: idrac
connection: local
name: Get system inventory
gather_facts: False
collections:
- dellemc.openmanage
tasks:
- name: Get system inventory
dellemc_get_system_inventory:
idrac_ip: "{{ idrac_ip }}"
idrac_user: "root"
idrac_password: "root"
register: system_inventory
- hosts: localhost
gather_facts: false
tasks:
- name: Write results to local output file
copy:
dest: "./output/system_inventory_output.json"
content: |
{% for host in groups.idrac %}
=== {{ host }} ==
{{hostvars[host].system_inventory}}
{% endfor %}
You might elect to use the template module rather than embedding the template in the content argument of the copy module, as I have done here.
I'm using Ansible to automate some configuration steps for my application VM, but having difficult to insert a new key-value to an existing json file on the remote host.
Say I have this json file:
{
"foo": "bar"
}
And I want to insert a new key value pair to make the file become:
{
"foo": "bar",
"hello": "world"
}
Since json format is not line based, I'm excluding lineinfile module from my options. Also, I would prefer not to use any external modules. Google keeps giving me examples to show how to read json file, but nothing about change json values and write them back to file. Really appreciate your help please!
since the file is of json format, you could import the file to a variable, append the extra key:value pairs you want, and then write back to the filesystem.
here is a way to do it:
---
- hosts: localhost
connection: local
gather_facts: false
vars:
tasks:
- name: load var from file
include_vars:
file: /tmp/var.json
name: imported_var
- debug:
var: imported_var
- name: append more key/values
set_fact:
imported_var: "{{ imported_var | default([]) | combine({ 'hello': 'world' }) }}"
- debug:
var: imported_var
- name: write var to file
copy:
content: "{{ imported_var | to_nice_json }}"
dest: /tmp/final.json
UPDATE:
as OP updated, the code should work towards remote host, in this case we cant use included_vars or lookups. We could use the slurp module.
NEW code for remote hosts:
---
- hosts: greenhat
# connection: local
gather_facts: false
vars:
tasks:
- name: load var from file
slurp:
src: /tmp/var.json
register: imported_var
- debug:
msg: "{{ imported_var.content|b64decode|from_json }}"
- name: append more key/values
set_fact:
imported_var: "{{ imported_var.content|b64decode|from_json | default([]) | combine({ 'hello': 'world' }) }}"
- debug:
var: imported_var
- name: write var to file
copy:
content: "{{ imported_var | to_nice_json }}"
dest: /tmp/final.json
hope it helps
ilias-sp's solution is great!
In my case, it lacked the case when we may have to create a base json file.
So I had to add this task in the beginning of the play:
- name: Ensure json file exists
copy:
content: "{}"
dest: /tmp/var.json
force: false
For people who are OK with custom ansible modules: https://github.com/ParticleDecay/ansible-jsonpatch works great!
With this you can simply do:
- name: append key/values
json_patch:
src: /tmp/var.json
operations:
- op: add
path: "/hello"
value: "world"
pretty: yes
create: yes
- name: update log
copy:
content: "{{ log | to_nice_json}}"
dest: "{{ log_file }}"
vars:
log: "{{ (lookup('file', log_file) | from_json) + ([{'job': (build_id if build_id != '' else 'dev'), 'keystore': ks, 'timestamp': ansible_date_time.iso8601}]) }}"
log_file: log/log.json
build_id: "{{ lookup('ENV', 'BUILD_ID') }}"
tags: log
Using Ansible "set_fact" module, I need to get repository url from json file using filters like "from_json". I tried in couple ways, and still doesn't get it how is should work.
- name: initial validation
tags: bundle
hosts: localhost
connection: local
tasks:
- name: register bundle version_file
include_vars:
file: '/ansible/playbook/workbench-bundle/bundle.json'
register: bundle
- name: debug registered bundle file
debug:
msg: '{{ bundle }}'
I get json that I wanted:
TASK [debug registered bundle file] ************************************************

And then I get error:
fatal: [127.0.0.1]: FAILED! => {"failed": true, "msg": "template error
while templating string: expected name or number. String: {{
bundle.('engine-server') }}"}
I many others ways like this loopkup, and it still fails with others errors. Can someone help to understand, how I can find each parameter and store him as "set_fact"? Thanks
Here is a sample working code to set a variable like in the question (although I don't see much sense in it):
- name: initial validation
tags: bundle
hosts: localhost
connection: local
tasks:
- name: register bundle version_file
include_vars:
file: '/ansible/playbook/workbench-bundle/bundle.json'
name: bundle
- debug:
var: bundle
- debug:
var: bundle['engine-server']
- name: set_fact some paramater
set_fact:
engine_url: "{{ bundle['engine-server'] }}"
The above assumes your input data (which you did not include) is:
{
"engine-config": "git#bitbucket.org/engine-config.git",
"engine-monitor": "git#bitbucket.org/engine-monitor.git",
"engine-server": "git#bitbucket.org/engine-server.git",
"engine-worker": "git#bitbucket.org/engine-worker.git"
}
