I am trying to persuade a bitbucket pipeline that employs a runner on our GKE based infrastructure to mount a directory from a GCE VM via NFS.
It seems that the outgoing traffic to NFS ports is blocked.
The pipeline has no problem accessing port 443 on an external web server.
No incoming traffic is visible to tcpdump on the NFS server.
Firewall logs show nothing being blocked.
The underlying runner containers (bb-k8s-runner and docker-in-docker) are both able to mount NFS directories from the server.
I'm wondering if anybody has a tip to enable the pipeline to access files on the NFS server.
