- Fix MYSQL_HOST/PORT: were referencing non-existent .Values.backup.mysql.host/port;
now correctly read from .Values.phpmyadmin.hosts[0] as documented in README
- Remove broken BACKUP_TIMESTAMP env var (shell command substitution does not
execute in k8s env vars; timestamp is already defined inside the script)
- Fix NFS readOnly: was always outputting "readOnly: false" even when
.Values.backup.nfs.readOnly was true; now renders the actual value
- Add MYSQL_HISTFILE=/dev/null to prevent mysql client from writing history
file when readOnlyRootFilesystem: true
- Fix variable name collision: renamed shell var DATABASES -> DB_LIST in the
all-databases branch to avoid conflict with the DATABASES env var
- Use /bin/bash (available in mysql:8.0 Debian image) for set -euo pipefail
and local keyword support
- Split retention find into separate *.sql and *.sql.gz patterns
- Add -mindepth 1 to empty dir cleanup to avoid removing the root backup dir
