+++ This bug was initially created as a clone of Bug #1807998 +++
Description of problem:
On Baremetal, and specially on IPv6 deploymnets, CRI-O's default setting of stream-address="" makes it bind to whichever address. That means that it can easily end up on the provisioning network.
How reproducible: Often
Steps to Reproduce:
1. Trigger a baremetal deployment
2. ssh to the different nodes
3. sudo ss -lptn | grep crio
Binds to provisioning network or some address not in the control plane.
Should be bound to a non VIP address on the control plane network (non-deprecated, non-link-local IPv6 address when IPv6 deployment).
You can check if crio got a stream address specified with a short command like in this example:
[core@master-0 ~]$ cat "/proc/$(pgrep crio)/cmdline" | xargs -0 echo
/usr/bin/crio --stream-address=fd2e:6f44:5dd8:c956::14 --enable-metrics=true --metrics-port=9537
