Added PortForwardingServiceProvider, StaticNatServiceProvider, rename
PasswordServiceProvider to UserDataServiceProvider(may rename to a better name
later).
Add related function for service providers.
DHCP range, domain name, etc. are the property of network, not virtual router
specific.
The focus of virtual router configuration would on separate enable/disable each
service it provided.
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
-Bringing add/delete/list of all external network devices under one unified API's (addNetworkDevice, deleteNetworkDevice, listNetworkDevice)
-Refactoring External network manager to work from both sets of API's add/delete/list NetworkDevice and add/delete/list External Firewall/LoadBalancer
- Make all API commands Async and add events
- Make BroadcatsDomainRange case insensitive
- Process all _networkElements to build the Service -> Provider map during NetworkMgr::configure()
It would cover the configuration of DHCPElement, VirtualRouterElement and
RedundantVirtualRouterElement.
Also add foreign key in domain_router table to reflect the domain_router is
created from which element and use what configuration.
Add configure command for these virtual router based elements. The commands
should be different for different elements.
The context of configuration would be added later.
- Create Zone changes and changes to data_center table to remove vlan, securityGroup fields
- Physical Network lifecycle APIs
- Physical Network Service Provider APIs
- DB schema changes
* moved all services to the separate table, map them to the network_offering+provider.
* added state/securityGroupEnabled properties for the networkOffering
* added ability to list by state/securityGroupEnabled in listNetworkOfferings api command
2) New service: SourceNat
Changes:
- Added a new interface 'PluggableService'
- Any component that can be packaged separately from cloudstack, can implement this interface and provide its own property file listing the API commands the component supports
- As an example have made VirtualNetworkApplianceService pluggable and a new configureRouter command is added
- ComponentLocator reads all the pluggable service from componentLibrary or from components.xml and instantiates the services.
- As an example, DefaultComponentLibrary adds the pluggable service 'VirtualNetworkApplianceService'
- Also components.xml.in has an entry to show how a pluggable service can be added, but it is commented out.
- APIServer now reads the commands for each pluggable service and when a command for such a service is called, APIServer sets the required instance of the pluggable service in the coomand.
- To do this a new annotation '@PlugService' is added that is processed by APIServer. This eliminates the dependency on the BaseCmd to instantiate the service instances.
Since we would introduce a way to specify each service provider in the network
offering, it's better for redundant virtual router as a separate service
provider.
Also isRedundant() flag in the network offering would be removed. Redundant
virtual router temporality won't work from now. Until we're able to add
different network elements/service providers in network_offering.
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.
