Counts the number of resources Checkov is scanning in the current or given directory
|
|
|
|
Useful to estimate Bridgecrew Cloud costs which are charged per resource
|
|
|
|
This can take a while to run on large directories with lots of resources
|
|
|
|
The first argument should be a directory (defaults to '.' for \$PWD)
|
|
The second argument onwards are passed as-is directly to the 'checkov' command
|
|
|
|
Alternatively, use a local .checkov.yaml config file to configure checkov settings,
|
|
such as multiple directories or skip directories, eg:
|
|
|
|
https://github.com/HariSekhon/Templates/blob/master/.checkov.yaml
|
|
|
|
|
|
Requires Checkov, awk and jq to be installed
