With the recent addition of advanced logic in a config file, the option to conditionally trigger steps in a job or to conditionally trigger a workflow is now available.

Specific logic statements can be used to create multiple nested conditions, that will always at the top level result in true or false -- which in turn determines if the workflow or steps are triggered.

Type	Arguments	true if	Example
YAML literal	None	is truthy	true/42/"a string"
YAML alias	None	resolves to a truthy value	*my-alias

# For AWS services, you can get the IP addresses using the following URL:
# https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html

#You can also filter the IP address using the APIs. I am sharing one such example for filtering with power shell:

Get-AWSPublicIpAddressRange -ServiceKey AMAZON -Region ap-south-1 | where {$_.IpAddressFormat -eq "Ipv4"} | select IpPrefix
