Please help in resolving this issue.

No repository file or test is named. Start by tracing the container startup path that reads POPULATE_DATABASE and compare database initialization for pdo_mysql in the reported Kubernetes environment. Reproduce the missing-table failure, then verify that a fresh MySQL-backed container creates wallabag_internal_setting before /login.
