This bug did not make the OSP 8.0 release. It is being deferred to OSP 10. Hi, We are planning to remove the command (-neutron-tunnel-types and -neutron-network-type ) Are there any customers that require these? Is there any use case here? (In reply to Ola Pavlenko from comment #5) > Hi, > > We are planning to remove the command (-neutron-tunnel-types and > -neutron-network-type ) > > Are there any customers that require these? Is there any use case here? I am lacking some more context here. Was this change proposed and discussed upstream? @Dan what is your take on this? Thanks, Nir (In reply to Ola Pavlenko from comment #5) > Hi, > > We are planning to remove the command (-neutron-tunnel-types and > -neutron-network-type ) > > Are there any customers that require these? Is there any use case here? I don't think that is a good idea. The neutron network type value doesn't just enable the network types, but also sets their preference. The first network type listed will be used as the default for tenant networks. If all possible networks are in use for a given network type, then new networks will be created with the next network type. This allows an operator to specify that tenant networks should be VLAN, but have a fallback to VXLAN if all VLANs are exhausted. We have too many customers who used these parameters in their original installation, who will be expecting those commands to work when they upgrade. Those same customers won't have those values specified in their THT environment files, so an upgrade which lacked that info could have the result of changing the Neutron network type which is the default for new tenant networks. Unfortunately, the command-line implementation of these parameters have shown multiple bugs over multiple releases, so there is certainly a lack of trust in those commands. The best way to set these values is by using THT parameters in an environment file. We can deprecate those parameters on the command-line and issue a warning for a release or two, then delete these params. That will alert users that the settings have changed and they should update their environment files to specify the desired network and tunneling type defaults. In any case, this discussion needs to happen upstream. Perhaps create a Launchpad BZ requesting that the command-line parameters be deprecated in favor of parameter_default settings in an environment file. Just to add some context to this, here is what is supposed to happen when you set those parameters: --neutron-network-type vlan,vxlan --neutron-tunnel-types vxlan This would result in tenant networks being created with type VLAN until all VLANs in the allowable range have been assigned, then vxlan networks being assigned after that. The admin would be able to create other network types, but with the default policy.json tenants would not have any control over their network type, and would get what the operator specified in those CLI params. Now, if I were to deploy without those parameters specified, the defaults would kick in. The default in this case is for tenant networks to be of type VXLAN. So if those CLI params were removed, and I did an upgrade without specifying network type in an environment file, the default tenant network would change from VLAN to VXLAN. As per Dan's comment, closing as wontfix and moving upstream. |
