[extra7132, extra7133, extra7113] Fails for DocumentDB instances

[h1008]

Hi,

the rds describe-db-instances command (as used by the checks extra7132, extra7133, and extra7113) also lists DocumentDB instances which do not support enhanced monitoring/multi-AZ/deletion protection [1]. So these checks fail if you have a DocumentDB cluster and it's not possible to fix the checks.

Proposed solution:

• Filter output of describe-db-instances command to ignore DB Instances with Engine "docdb".
• Add a specific check for deletion protection for docdb clusters (using the command docdb describe-db-clusters).

[1] DocumentDB does support deletion protection, but it's a configuration option for clusters, not individual instances. See result of docdb describe-db-clusters.

Thanks for let me know, in the meantime you can use the whitelist feature to prevent that fail.

Can you please try changing the checks with this query instead and see if that fixes the issue? --query 'DBInstances[?Engine != docdb].DBInstanceIdentifier'. If it does please, feel free to send a PR with a fix. Thanks

It almost worked - I just had to set the string in single quotes: --query "DBInstances[?Engine != 'docdb'].DBInstanceIdentifier".
I'll prepare a PR.
