egrep -v "^$|^#" /etc/ssh/sshd_config_dirty  ← easy

egrep -v "^:space:*$|^#" /etc/ssh/sshd_config

egrep -v "^:space:*$|^#" sshd_config

egrep -v "^:space:*$|^ \*|^.*/\*|^/\*|^$"

Mysql operator S3 innodbcluster backup SECRET CONFIG

-
[ERROR] [backup] Backup failed with an exception: Util.dump_instance: Argument #2: The AWS access and secret keys were not found in: environment variables     mysql do not provide a good documentation about mysql operator. ORACLE WANT YOU TO USE OCI! USE OCI cmon.  mysql operator wants aws "cretentials" file down the "/mysqlsh/.aws folder, it does this in pod through VolumeMount the secret file, nothing about to worry about.  PS: If you are trying to backup to an s3 endpoint with self signed or with private ca certificate, loose all hopes. I do not find a solution about that.  cat secret   [default]   aws_access_key_id=REDACTED aws_secret_access_key=REDACTED cat secret | base64 -w 0 W2RlZmF1bHRdIAphd3NfYWNjZXNzX2tleV9pZD1SRURBQ1RFRAphd3Nfc2VjcmV0X2FjY2Vzc19rZXk9UkVEQUNURUQKCg==                            ...
