<# .Synopsis Sets the Certificate on a Application Load Balancer .DESCRIPTION Sets the Certificate on a Application Load Balancer .EXAMPLE Set-AWSWindowsHelpersALBCertificates -originalCertARN "arn:aws:iam::123456789012:server-certificate/2017_wild_example_com" -replacementCertARN "arn:aws:acm:us-west-2:123456789012:certificate/0e450187-a4b4-452f-a88b-c1d17dfaf749" .INPUTS originalCertARN - ARN of the original AWS certificate to be replaced replacementCertARN - ARN of the replacement AWS certificate to be used on the load balancer loadbalancerARN (optional) - ARN of the Application Load balancer. If not supplied all load balancers will be checked if the certificate is present Credential (optional) - Credential to use for AWS commands if supplied ProfileName (optional) - ProfileName to use for AWS commands if supplied .FUNCTIONALITY Cmdlet replaces all the listeners which are using the original certificate ARN with the replacement certificate ARN.
