Description

Unable to call Podman REST API from web application due to CORS. How do I enable CORS on Podman REST API.
Able to overcome CORS issue for GET methods by installing firefox plugin https://mybrowseraddon.com/access-control-allow-origin.html but not working for POST methods.

Steps to reproduce the issue:

Start Podman with: podman system service --time=50000 tcp:localhost:7080 --log-level=debug --time=0
Manually create dummy pod with: podman pod create dummy
On JSFiddle: Run the following with Javascript + jQuery 1.9.1
$.get('http://localhost:7080/v1.40.0/libpod/pods/dummy/json').then(response=> console.log({response})).catch(error=>console.log({error}));

Describe the results you received:

Received CORS error:

Invalid X-Frame-Options header was found when loading “https://fiddle.jshell.net/_display/?editor_console=true”: “ALLOWALL” is not a valid directive.
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:7080/v1.40.0/libpod/pods/dm-perception-pod-0/json. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

{ "error": { "readyState": 0, "status": 0, "statusText": "error" } }
