innodb_redo_log_capacity passed as '' or 'auto' from the delivery
payload previously bypassed the memory-based tier calculation and was
rendered verbatim into the instance config. Fall back to the automatic
tier when the value is empty or 'auto'.
Add a compensating playbook that removes a single delivered MySQL
instance from a target host. The rollback scope is pinned by
target_hosts + instance_name + data_disk, with pre-task assertions
rejecting instance names or disk paths outside the delivery layout
to prevent accidental deletion.
- stop and disable mysql-delivery@<instance>.service, reset failed state
- remove instance data dir, install dir, config file and run dir
- 8.0 from Ubuntu archive, 8.4 from MySQL official APT repo
- 5.6/5.7 not supported for now; enforce one MySQL series per host
- Sync Go version whitelist with the playbook package map
- Add topology/port/data_disk, DB options and 8 advanced parameters
with whitelist validation, rendered via extra_vars into the playbook
- Hybrid port allocation over pool 13306-13999
- Tighten bounds: memory 2048-65536 MiB, storage 20-2000 GiB
