it kind of depends on what faild and where.
you willl ahve to rebootstrap the node if you reinstall it.

most of the time if somethign fails with kolla you can just fix the problem in your config or whatever caused it and re run deploy.
you generally shoudl not need to reinstall the os. running kolla-ansible destory will generally clean up the env fully if it comes to that.


if you do remove the node and try to re add it its generally better not to reuse hostnames.
you can but then you might need to do service specific cleanups in some cases.

in this partical case it was jsut complaing that localhost does not have docker.
localhost (presumable your laptop/desktop) does not need docker unless you intende to buidl the kolla images your self inwhich case the fix is
just install docker and if you run prechecks again it should pass.
