In view of the foregoing technical problems, embodiments of the present invention provide a network creation method, device, apparatus, and computer storage medium, which may be used to implement a virtual machine direct access management service in a cloud platform.
Based on the above description, the following examples are proposed
First embodiment
An embodiment of the present invention provides a network creation method, and fig. 1 is a flowchart of the network creation method according to the embodiment of the present invention, and as shown in fig. 1, the flowchart may include:
step 101: and monitoring a message for creating a network on a first node of the cloud platform, which provides a management service.
In practical application, a node for providing management service by the cloud platform may be one node or a plurality of nodes; the embodiment of the present invention does not limit this.
As an embodiment, a management-service-agent (management-service-agent) component may be added to the first node, and then the management-service-agent component may be used to listen to the message for creating the network.
In practical applications, a first component for implementing the management service of the first node may be disposed on the first node, and the first component may broadcast the message for creating the network when receiving the request for creating the network, so that the management-service-proxy component may listen to the message for creating the network.
Step 102: and when the message for establishing the network is monitored, a virtual port is established, the virtual port is added into the virtual switch of the first node, and corresponding DNS service is configured for the virtual port.
In practical application, a virtual port may be created in a first host, where the first host is a host corresponding to the first node.
It can be understood that, since the virtual port is added to the virtual switch of the first node and the DNS service is configured for the virtual port, when the virtual machine is used to access the network, the virtual machine can access the first node based on the DNS service configured for the virtual port and the virtual switch, and the first node can provide the management service, and further, the virtual machine can directly access the management service of the cloud platform; that is to say, the network creation method of the embodiment of the present invention replaces a method for implementing a virtual machine to access a cloud platform management service by manually configuring a network device in the related art, and can meet a requirement for interworking between the virtual machine and the cloud platform management service.
In practical applications, the steps 101 to 102 may be implemented by a Processor in the first node, and the Processor may be at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a Central Processing Unit (CPU), a controller, a microcontroller, and a microprocessor.
For the implementation manner of configuring the corresponding DNS service for the virtual port, for example, a mapping relationship between the identification information of the first host and the IP address of the virtual port may be sent to the DNS server; here, the DNS server is a device outside the first node, and the DNS server may store a mapping relationship between the identification information of the first host and the IP address of the virtual port, and may further configure a corresponding DNS service for the virtual port; in this manner, virtual machine access to a virtual port in the first host through the DNS server is facilitated.
In the embodiment of the present invention, the type of the identification information of the first host is not limited, for example, the identification information of the first host may be a name or other types of identification information.
For a specific implementation of creating a virtual port, illustratively, a virtual port creation request may be sent to a first component in a first node; then receiving a response result aiming at the virtual port creating request sent by the first component, and creating the virtual port according to the response result; because the first component is a necessary component for realizing network creation on the cloud platform, the process of creating the virtual port conforms to the service logic of the cloud platform, and the realization is more convenient.
In practical applications, the management-service-agent component may be used to send a virtual port creation request to the first component, and the first component may send a response result to the virtual port creation request to the management-service-agent component after receiving the virtual port creation request.
Further, after sending the virtual port creation request to the first component, routing information may also be received, where a destination IP address indicated by the routing information is a virtual port IP address. Therefore, the virtual machine can conveniently access the virtual port according to the routing information.
Optionally, after receiving the virtual port creation request, the first component may further broadcast a corresponding port creation packet. In practical application, after the first component broadcasts a port creation message to the outside, a second node of the cloud platform can receive the port creation message, the second node is used for providing computing service, and the port creation message carries a virtual port IP address; thus, the second node can generate corresponding routing information according to the virtual port IP address in the port creation message, and can send the generated routing information to the first node; because the existing cloud platform has nodes for calculating the routing information, the manner for acquiring the routing information conforms to the service logic of the cloud platform.
Second embodiment
In order to further embody the object of the present invention, the first embodiment of the present invention is further illustrated.
In the second embodiment of the present invention, a cloud platform is taken as an openstack cloud platform for example; a management-service-proxy component is newly added in the openstack cloud platform, and the management-service-proxy component runs on all management nodes (i.e. nodes providing management services) for exposing services for the virtual machine, and can be responsible for monitoring the creation of network resources, creating virtual ports (such as neutron ports) and registering service domain names with a DNS server.
Here, the management-service-agent component runs on each node where the openstack management service is installed, for example, the openstack management service may be a neutron-service (neutron-server), nova-api, or the like; the management-service-agent component can be responsible for monitoring the message for establishing the network, if the administrator establishes the management network, the management-service-agent component sends a request for establishing a port to the neutron-server, and simultaneously establishes a virtual port on the node provided with the openstack management service and adds the virtual port into the openvswitch; after the network is created, the management-service-proxy component writes the host name (hostname) of the host where the management-service-proxy component is located and the IP address of the virtual port into the DNS server.
Fig. 2 is a schematic diagram of a deployment model of an openstack cloud platform according to an embodiment of the present invention, and referring to fig. 2, a management node 1 and a management node 2 are first nodes, a computing node is a second node, in the management node 1, a Neutron-server represents a first component, an Openvswitch represents a virtual switch, a management-service-agent represents a management-service-agent component, and a Neutron-Openvswitch-agent represents an agent component of the virtual switch; in the management node 2, nova-api represents a first component, openvswitch represents a virtual switch, management-service-agent represents a management-service-agent component, and neutron-openvswitch-agent represents an agent component of the virtual switch; in the computing node, neutron-openvswitch-agent represents a proxy component of a virtual switch, openvswitch represents the virtual switch, and nova-computer represents a computing component in the computing node. In fig. 2, eth0 indicates a communication port of the management network, and eth1 indicates a communication port of the service network.
Fig. 3 is a schematic diagram of an interaction flow of a network creation method according to an embodiment of the present invention, and with reference to fig. 2 and fig. 3, the interaction flow of the network creation method may include:
1. a network named management-service-net is created by an administrator user, the name being predefined.
2. Creating a network triggers the neutron-server to send a network creation (create-net) broadcast, to which the management-service-broker component subscribes; thus, the management-service-agent component, upon receiving the broadcast, is equivalent to listening for messages that create the network.
3. After receiving the network creation broadcast, the manager-service-agent component calls a network-server representational state transfer (rest) application programming interface (api) and sends a virtual port creation (create port) request to the network-server, so that a port (virtual port) is created in the network named management-service-net, and the type of the port is management port.
4. After receiving the virtual port creation request, the neutron-server broadcasts a port creation message.
5. After receiving the virtual port creation request, the neutron-server may return a response result for the virtual port creation request to the management-service-proxy component.
After receiving the response result, the management-service-agent component may create a virtual port on the host corresponding to the first node and configure an IP address of the virtual port; the management-service-agent component may also add virtual ports to the virtual switch openvswitch.
6. The manage-service-proxy component configures the DNS service.
Specifically, the management-service-proxy component may send a mapping of the host name of the first host and the IP address of the virtual port to an external DNS server.
7. After receiving the port creation message, the neutron-openvswitch-agent located in the compute node may configure the flow table of the compute node. Specifically, a flow table may be configured to route a packet having a destination IP address that is an IP address of a virtual port to a first node that exposes a management service.
Fig. 4 is a schematic diagram of a virtual port of a virtual machine accessing a first node in an embodiment of the present invention, and referring to fig. 3, openstack-tap is a virtual port created by a management-service-agent component, openvswitch is a virtual switch, VM denotes a virtual machine, and eth1 denotes a communication port of a service network.
With reference to fig. 2, fig. 3 and fig. 4, it can be seen that after the management node 1 creates a virtual port, the virtual machine can access the openstack management service, which is described in detail below.
Referring to fig. 4, after a virtual machine needing to access openstack management service is started, a DNS service needs to be configured, then the openstack management service is accessed by accessing a "domain name + port", the domain name is resolved by the DNS and finally converted into an IP address of a virtual port created by a management-service-proxy component, and an access packet of the virtual machine is influenced by an ovs (openvswitch) flow table and routed to a designated node (i.e., a management node 1); obviously, when the traffic reaches the virtual port, it is equivalent to reaching the management node 1 providing the management service, i.e., the traffic can be received by the openstack management service process.
It can be seen that, in the embodiment of the present invention, by adding a management-service-agent component in the framework of the openstack cloud platform, creation of a network, such as a management network, can be automatically discovered, and a virtual port is automatically created on the first node exposing the management service, so that the configuration of a network device does not need to be modified manually, and meanwhile, the business logic of the openstack cloud platform is met.
Further, in the embodiment of the present invention, by registering the host name of the first host and the IP address of the created virtual port in the DNS server, the problem that the address of the virtual machine for accessing the management service changes due to a change in the IP address can be avoided, that is, the virtual machine directly uses the domain name to access the openstack management service, thereby avoiding inconvenience caused by using a fixed IP.
Furthermore, the embodiment of the invention can configure a special flow table for the flow of the virtual machine access management service by reasonably configuring the service logic of the management-service-agent component, so that the flow can directly reach the first node; in addition, the embodiment of the invention also illustrates how to implement the business process of the virtual machine access management service in the neutron framework.
