I want to have my hosting provider whitelist the IP addresses used during my build pipelines so that I can use rsync commands to automate deployment. However, the VPN continues to block my rsync attempts from the pipelines.
My guess is that this is because I'm using a container in my pipeline and the IP address for the container (using ifconfig) is not the same as the list of IP addresses that Bitbucket specifies for Bitbucket Pipelines. (The list of IP addresses provided by Atlassian can be found at the bottom of this page.)
Since ifconfig doesn't return an IP address in that list, how can I determine a predictable IP address (or list) to give to my hosting provider to make sure that my container's rsync commands are not blocked by the firewall?
