I’m trying to move from managing firewall rules for multiple domains in the UI to managing them with Terraform. I’m having problems with duplicate filters when replacing the firewall rule.
First I created the firewall rule in the UI to compose the filter expression and test it out. Then when I wanted to add the firewall rule and filter to the code I deleted the rule and let Terraform recreate it. It appears that when deleting the firewall rule in the UI it does not also delete the related filter. When I ran terraform apply and it tried to create the filter I got the following error.
"code": 10102, "message": "config duplicates an already existing config",
So is it the case that I can’t create another filter with the same expression?
This time I ended up deleting the existing filter by calling the API but this isn’t ideal.
Is there some better way to accomplish this?
