Summary of changes: Database changes will be rollbacked while applying the LB rule to the Netscaler device.
- Database changes will be rollbacked to previous state during the following Lb API's:
1) assignVM to LB rule
2) remove VM from LB rule
3) updateLb rule
4) deleteLb rule
5) create/attach sticky policy to Lb rule
6) delete sticky policy from Lb rule
- Database changes of the Lb rule will be not be rolledback during:
1) Removing IP
2) removing VM
Summary of Changes:
- created a generic way for LB rule validations, so as LB device(like Haproxy) specific validations can be done syncronously.
- Removed asyncronous validations from Haproxy and done syncronously.
When elb capability is enabled on the network offering, we:
1) on each createLB command:
* associate ip address to the LB rule owner
* create LB rule
2) on each deleteLb command:
* delete the rule
* disassociate ip address
The rule belongs to the owner, so proper usage events are generated
2) Added elasticIp and elasticLb network capabilities. Provided support to create network offering with these capabilities.
3) Added one more default network offering having elasticip and elasticlb
4) Public network support to Basic zone. You can associate/disassociate IP addresses now
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
- Create Default physicalnetwork and add traffic types while creating a zone
- DeleteProvider should error out if there are networks using the provider.
- Other validations
- 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.
As DhcpElement/VirtualRouterElement/RedundantVirtualRouterElement is decided to
be the service provider of the physical network, this API should be called to
add a new element, with correlated network service provider ID.
Then e.g. ConfigureVirtualRouterElementCmd should be called to configure and
enable the element.
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()
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.
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.
