Fixed In Version:	4.5.0	Doc Type:	Bug Fix
Doc Text:	Cause: Ironic containers in OCP would fail to start if the user defined "PROV_IFACE" interface was configured for IPv6 but to only use link-local addressing as opposed to a globally routable addressing. Consequence: Ironic containers would fail to start. Fix: The container start-up script has been modified to accept link-local addressing in addition to global addressing. Result: Containers will now start the interface definedby "PROV_IFACE" only contains link-level addresses as opposed to globally routable addresses.	Story Points:	---

Description Juan Manuel Parrilla Madrid 2020-05-08 14:49:02 UTC

Description of problem:

When using routable IPv6 addresses for the provisioning network. The previous grep command only matched local unicast addresses, this new grep will match any IPv6 address, but the link local scope.

The httpd container keeps waiting for "PROV_IFACE" to be configured otherwise.

Version-Release number of the following components:

openshift-baremetal-install 4.4.0-0.nightly-2020-05-07-005846
built from commit fb65b95076665c794e7c1cc148f56722761d0d31

How reproducible:

Steps to Reproduce:
1. Use the installer to deploy an IPv6 cluster
2. Wait for the Bootstrap VM to boot it up
3. Check logs on podman image "http", it gets stuck on:


Actual results:
http container gets stuck on:
