Recover deleted folder in Google Cloud Storage

I tested with following host and path rules and verified with http://load-balancer-ip/file-name and was able to access the file present within the root of the bucket defined in backend configuration of the load balancer.

| Hosts | Paths | Backends |

| WEB-SERVER-IP | /* | Backend-service-name |

Try copying the image within the root of the your bucket defined in backend configuration of Load balancer and add or change the "Host and path rules" to define path as "/*" (without quotes). You should be able to access the image using "gs://bucket-name/file-name" or "http://load-balancer-ip/file-name"

Hope it helps.

You can regain access to the object by assigning an appropriate role, such as roles/storage.objectAdmin, to yourself or another member.

• Go to IAM under IAM & admin session
• Add members, and select Storage > Storage Object Admin role

Note that doing so provides access to all objects in the bucket or project.
