In Ocata all live-migration over ssh is performed on the default ssh port (22).
In Pike the containerized live-migration over ssh is on port 2022 as the
docker host's sshd is using port 22.
To allow live migration during upgrade we need to temporarily pin the Pike
computes to port 22 and in the final converge we can switch over to port 2022.
This patch make the necessary puppet-tripleo change to allow this:
- Adds support in sshd profile for listening on multiple ports.
- Adds a profile to allow proxying to the containerized sshd from the
baremetal sshd
