Bitbucket pipeline interaction with the self-hosted runners created in the AWS EC2 private?

How does the Bitbucket pipeline interact with the self-hosted runners created in the AWS private subnet? Should I create the EC2 instance behind a public-facing NLB (Network load balancer)?

Welcome to the community.

Unfortunately, we can't advise much on this since it's a 3rd party hoster. However, I believe trying with and without public-facing NLB won't harm you to see if Runner could communicate with Bitbucket.

The general idea is that as long as Runner can communicate with Bitbucket cloud via HTTPS, it should be possible. You might want also to check the list of IPs to allow:
