commit 4acbf4fee389129611541b6d7db999dd5ddb45ad Author: Julia Kreger <[email protected]> Date: Thu Jul 12 15:43:15 2018 -0700 ironic: provide facilities to gracefully navigate versions For quite some time, the nova virt driver has invoked the ironic python client library with a static microversion pin which causes operators to have a failed nova-compute process upon out of order upgrades, as well as causes ironic's grenade CI jobs to break every cycle when the pin is changed to a version released in the current cycle due to established community agreement as well as the grenade testing framework limitations. In order to gracefully navigate this, python-ironicclient has accepted a list of possible versions to negotiate since 2.2.0. This patch provies a mechanism to validate if we are able to send a request that was added at a specific version, allowing for minimal code changes and for logic to only be centered around newer features being added.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1739440 Title: Ironic virt driver is hardcoding Ironic API microversion Status in OpenStack Compute (nova): Fix Released Bug description: Doing this imposes a minimum cap on the Ironic version Nova can work with, even if potentially it can use older version (with somewhat reduced functionality, for example, booting from volume is optional). This complicates upgrades by enforcing a strict ordering between Ironic API and Nova compute. It also makes using mixed versions impossible. We should make the virt driver negotiated a version, and then gracefully downgrade the feature set. See some thoughts at https://etherpad.openstack.org/p/ironic-api-version-negotiation. If time allows in the Queens release, we would like to make the already merged configdrive change backward compatible with Pike.
