Is it possible to concatenate like below?

  • name: Retaining latest backup directory
    shell: find $(pwd)/backup -type d -prune -exec ls -d {} ; |tail -1
    register: import_back_up_dir

  • name: Import dashboard
    grafana_dashboard:
    state: present

message: Updated by ansible
overwrite: no
path: “{{ item }}”
with_items:

  • “{{ import_back_up_dir }} + SonarQube_Dashboard.json” >>>>>> I am trying to concatenate like this however this is not working - could some one please suggest how can we achieve this concatenation.

this is not working - could some one please suggest how can we achieve this concatenation.

Maybe you give us the objective of your task first ...

Thanks Stefan for looking into this. actually I want to import some grafana dashboards and I need to map this import_back_up_dir (which I cannot hardcode) to appropriate json files. so I want to find a way to concatenate these.

Concatenate need to be done in inside of {{ }} and use tilde

"{{ import_back_up_dir ~ 'SonarQube_Dashboard.json' }}"

HI kai,

thanks for the response. however I am trying to use inside looping with_items it isn’t working.

“msg”: "error : Can’t load json file [Errno 2] No such file or directory: '{\‘stderr_lines\’:

trying like this

with_items:

  • “{{ dashboards_imported_from_latest_backup ~ ‘/Artifactory_Monitoring.json’ }}”

This will only be one item so you don't need to use with_items.
Anyway, since you only need the text it should be like this

  with_items:
    - "{{ dashboards_imported_from_latest_backup}}/Artifactory_Monitoring.json"

Thanks Kai. No actually this is not going to be one item only as it should be done for almost 7-8 json files. so i think the below trick you shown I am going to try that right now and see if that works forme. Thanks again , cheers!

I tried the above what Kai suggested however that is not working and unable to get the particular json for me from the specific backup dir. However I could find a way to get this done as shown below - this way we can get the output from the variable line by line.

with_items:

  • “{{ dashboards_imported_from_latest_backup.stdout_lines[2] }}”
  • “{{ dashboards_imported_from_latest_backup.stdout_lines[3] }}”
  • “{{ dashboards_imported_from_latest_backup.stdout_lines[4] }}”
