We have a SQL server hosted on a cloud VPS and a kubernetes cluster hosted on here (Digital Ocean)
Our server the SQL sever sits on, has firewall rules to only allow whitelist IPs to connect to the SQL server. So currently we add the IPs to each of the kubernetes nodes so they can each connect the the SQL server.
This obviously isn’t scalable and is a challenge to maintain as any new node we have to add the IP to the firewall rule, etc…
In AWS we got round this by using a NAT gateway which allowed us to only need to whitelist the one IP.
Is there anything like that in Digital Ocean that we can use for database access of our nodes without whitelisting each’s IP, or are there any other alternatives to this issue on DO?
Thank you :)
