Hi, The Kolla project is planning to support SLURP upgrades [1] in the Caracal release cycle, allowing users to upgrade from Antelope to Caracal. There are two areas in which I'd like to request information from the various project teams. # 1. SLURP support We understand that for various reasons there can be a gap between TC resolutions and implementation across projects. Using some rudimentary grepping through various codebases I found that many projects have added the grenade-skip-level job (or a variation of it) to their CI pipelines, and a few mention SLURP in their release notes. There's little mention of it in documentation at this stage. AFAICT the following projects have SLURP upgrade jobs: Cinder, Glance, Ironic, Manila, Neutron, Nova, Octavia While I could not find a SLURP job in these: Barbican, Bifrost, Blazar, Cloudkitty, Designate, Heat, Horizon, Keystone, Magnum, Placement Question: Does your project explicitly support SLURP upgrades? Do you have or are you planning to add testing and documentation for SLURP upgrades? # 2. Rolling SLURP upgrades The TC resolution [1] states that rolling upgrades are optional for SLURP releases. This could affect the upgrade procedure required in Kolla Ansible. Nova mentions in its Antelope release notes that it supports rolling SLURP upgrades, but I could not find any information from other projects. It would be helpful if this was documented for each project. Question: Does your project support or plan to support rolling upgrades? If changes to the upgrade procedure for SLURP are required, are they documented? Thank you in advance for your responses. Apologies if I have missed any obvious source of information on this.
