Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a block diagram of a system 1 for communicating hosts with a management apparatus according to the present invention, and as shown in fig. 1, the system 1 includes a cloud computing carrier host 10 and a cloud computing carrier management apparatus 20. The host 10 includes a cloud container 11 and a host management unit 12. Therein, the host 10 may include a plurality of cloud containers 11. Each cloud container 11 includes a sending unit 111 and a first conversion unit 112 the host management unit 12 includes a sharing unit 121 and a second conversion unit 122. The management apparatus 20 of the cloud computing operator includes a management unit 21, wherein the management unit 21 may be a plurality (e.g., a database module, a data sampling module, etc.). In fig. 1, only one cloud container 11 and one management unit 21 are shown for the sake of simplicity.
Wherein the transmitting unit 111 transmits the first format data in the cloud container 11 to a predetermined network protocol port associated with the management unit 21 in the management apparatus 20; the first conversion unit 112 receives the first format data from the predetermined network protocol port, converts the first format data into the shared format data, and generates a tag associated with the management unit 21 according to the predetermined network protocol port; the sharing unit 121 shares the sharing format data and the tag to the host management unit 12; the second conversion unit 122 converts the shared format data in the host management unit 12 into the first format data, generates the network protocol address and the port of the management unit 21 according to the label in the host management unit 12, and sends the first format data to the management unit 21 according to the network protocol address and the port.
Fig. 2 is a flowchart of a method of communicating a cloud container with a management device according to the present invention. An embodiment of the present invention will be described in detail with reference to fig. 1 and 2.
In step S21, the transmission unit 111 in the cloud container 11 transmits the first format data in the cloud container 11 to a predetermined network protocol (IP) port associated with the management unit 21 in the management apparatus 20.
Wherein the first format data is for example data in TCP/IP format, the sending unit 111 sends the data in TCP/IP format to a predetermined IP port, which is for example associated with a managing unit 21 in the managing device 20, which managing unit 21 is for example a database module 21.
In step S22, the first conversion unit 112 receives the first format data from the predetermined IP port, converts the first format data into the shared format data, and generates a tag associated with the management unit 21, for example, associated with the database module 21 in the management apparatus, according to the predetermined IP port.
Here, the first conversion unit 112 receives data in, for example, TCP/IP format from the above-mentioned predetermined IP port, and converts the data in TCP/IP format into shared format data, which is, for example, unix socket file format data. Wherein the predetermined IP port is located in the first conversion unit 112.
In step S23, the sharing unit 121 in the host management unit 12 shares the sharing format data and the tag to the host management unit 12. In this example, for example, the sharing unit 121 is an unix socket file, and the sharing unit 121 shares unix socket file format data and a tag associated with the database module 21 to the host management unit 12.
The cloud container 11 and the host management unit 12 in the host 10 are isolated from each other, and the sharing format data converted by the first conversion unit 112 in the cloud container 11 can be shared with the host management unit 12 by the sharing unit 121 in the host management unit 12, so that the host management unit 12 can receive the sharing format data. The shared format data is not limited to unix socket file format data, but may be other format data that can be shared to the host management unit 12.
In step S24, the second conversion unit 122 in the host management unit 12 converts the shared format data in the host management unit 12 into the first format data, generates the network protocol address and port of the management unit 21 according to the label in the host management unit 12, and sends the first format data to the management unit 21 according to the network protocol address and port.
Here, the second conversion unit 122 converts the unix socket file format data in the host management unit 12 into data in the TCP/IP format, for example. In the second conversion unit 122, a predetermined table is stored, in which correspondence relationships between different tags and network protocol (IP) addresses and ports of different management units 21 are defined, and which is shown in table 1, for example.
TABLE 1
Management unit Label (R) IP address and port
Database module 1 IP1, Port 1
Data sampling module 2 IP1, Port 2
Time module 3 IP1, Port 3
In this example, as described above, the tag shared to the host management unit 12 is associated with the database module 21, and then in connection with table 1, the tag is 1. The second translation unit 122 finds the IP address and port of the corresponding database module from table 1 as "IP 1, port 1" according to tag 1.
The second conversion unit 122 then sends the data in TCP/IP format to the corresponding database module 21 according to the found "IP 1, port 1". In this manner, the cloud container 11 in the host 10 can be made to communicate with the management unit 21 in the management apparatus 20.
In addition, when the management unit 21 needs to transmit data to the cloud container, the data may be transmitted in the reverse path to that described above.
In the invention, when a cloud container rented by a user in a host of a cloud computing operator needs to communicate with a management device of the cloud computing operator, the cloud container can not directly send data in a TCP/IP format to the management device, but sends the data through a host management unit in the host. In this way, the cloud container rented by the user cannot directly access the management apparatus, thereby preventing the user from controlling the entire management apparatus. Therefore, network security can be improved, communication between the cloud container and the management device can be achieved in a simple and convenient operation mode, and research and development and operation costs are extremely low.
Further, although the cloud container 11 and the host management unit 12, which are also in the host 10, are isolated from each other, the cloud container 11 and the host management unit 12 may share data in a local file format. Accordingly, data in the local file format (e.g., unix socket file format data) is mutually transmitted through the first conversion unit 112 and the sharing unit 121, so that the cloud container 11 transmits the data in the TCP/IP format to the corresponding management unit 21 in the management apparatus 20 through the second conversion unit 122 in the host management unit 12. Therefore, the cloud container and the management device can be communicated in a simple and convenient operation mode, and research, development and operation costs are extremely low.
The present invention also provides a nonvolatile storage medium on which a program for causing a cloud container in a host to communicate with a management apparatus is stored, the program being executed by a computer to implement a communication method, the program including:
sending an instruction to send the first format data in the cloud container to a predetermined network protocol port associated with a management unit in the management device;
a first conversion instruction, which is used for converting the first format data into shared format data and generating a label associated with the management unit according to the predetermined network protocol port;
a sharing instruction, which shares the sharing format data and the label to a host management unit in the host, wherein the host management unit is isolated from the cloud container;
and a second conversion instruction, which is used for converting the shared format data in the host machine management unit into the first format data, generating a network protocol address and a port of the management unit according to the label in the host machine management unit, and sending the first format data to the management unit according to the network protocol address and the port.
While the present invention has been described in conjunction with specific embodiments, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended that such alternatives, modifications, and variations be included within the spirit and scope of the appended claims.
