Introduce the concept of Ip Deployer. The IP deployer would be responible for
apply IP to the element. Most element's IP deployer is itself, but it can be
someone else if we want to implement inline mode in the future.
only owner of the network can access it; if it's domain - all accounts in the domain and domain children can have an access.
* aclType replaces 2 old fields: isShared and isDomainSpecific.
* All 2.2.x account specific networks will have aclType=Account; 2.2.x Domain specific networks - aclType=domain; 2.2.x Zone level networks - aclType=Domain with domainId = Root domain id
- ListSupportedNetworkServiceProvidersCmd will now return Providers along with its element's services and boolean 'canEnableIndividualServices' that indicates if for this Provider services can be enabled/disabled
- add & update NetworkServiceProvider changed to take in the list of services to enable. While adding a provider, if list is null then all services supported by the element are enabled by default.
- ListNetworkServices enhanced to take in a provider name and returns services of that specific provider.
* can be specified for Shared network only
* if not specified for the Shared networks, try to locate it based on the zoneId and tags. If tags is not null, pick up first physicalNetwork from the zone that has matching tags. If tags is null, and there are none/more than 1 physical netwroks in the zone, error out.
Added PortForwardingServiceProvider, StaticNatServiceProvider, rename
PasswordServiceProvider to UserDataServiceProvider(may rename to a better name
later).
Add related function for service providers.
2)Re-apply all existing firewall rules as a part of implement call. TODO: Cleanup all existing rules from the backend (leave them in the DB) as a part of shutdown call
TODO:
- Still leaving the provider columns in data_center schema as-is for CloudKit and BareMetal
- ExternalNetworkDeviceMgrImpl still needs to fix the dataCenter.setProviders calls and externalNetworkApplicance usage checks to see if zone has external networking.
Limitations:
* can't upgrade to the network offering with lesser number of services
* can upgrade only when the service provider of the original offering is not external (domR, dhcp, elb) to the external type of the provider
In the past, the NetworkElement would cover almost all the functionality that
e.g. virtual router can cover: firewall, source NAT, static NAT, password,
VPN... So anyone want to implement the NetworkElement would have to implement
these service's specific methods, even it wouldn't support it. Also, if we want
to find a e.g. FirewallServiceProvider, we have to proceed all the current
network service providers, to call a method to know if it support such service.
That's neither elegant nor scaling way to do it.
As the first step, this patch separates each ServiceProvider from NetworkElement
(there are some interface already out of NetworkElement, so this patch slightly
modifies them too), and only the class would implement the correlated interface, would
have the ability to do these services.
