Thesecond container 300 may implement unidirectional communication with thefirst container 200, and thesecond container 300 performs network configuration on thefirst container 200 according to the network configuration information in the network configuration request.
Referring to fig. 3, fig. 3 is a flowchart of a network configuration method applied to the network device 100 in fig. 1 according to an embodiment of the present application, and with reference to fig. 2, the following describes various steps included in the method in detail.
Step S310, receiving a network configuration request sent by the first container.
Thecontainer engine 400 receives a network configuration request sent by thefirst container 200, wherein the network configuration request includes a container address of thefirst container 200, a container address of thesecond container 300, and network configuration information that thefirst container 200 needs to be configured. The network configuration information may be network configuration information obtained by an interface management process in thefirst container 200 according to a version of a network operating system when thefirst container 200 is started, or network configuration information obtained by the interface management process in the operation process of thefirst container 200 according to service needs.
In the network configuration request, the container address of thefirst container 200 is a source address, the container address of thesecond container 300 is a destination address, and the network configuration information is specific content. The container address is recorded in the network configuration request, so that thefirst container 200 transmits the network configuration information to thesecond container 300 through thecontainer engine 400, and the configuration of the own network is realized through thesecond container 300. In the present embodiment, thefirst container 200 may interact with thecontainer engine 400 through communication via a docker command.
Specifically, thefirst container 200 may send a docker command through a docker Application Programming Interface (API), where the docker command includes a network configuration request.
Step S320, sending a network configuration request to the second container, where the network configuration request is used to enable the second container to perform network configuration on the first container according to the network configuration information in the received network configuration request.
After receiving the network configuration request, thecontainer engine 400 forwards the network configuration request to thesecond container 300 according to the destination address in the network configuration request.
After receiving the network configuration request, thesecond container 300 performs network configuration on thefirst container 200 according to the network configuration information in the network configuration request and the container address of thefirst container 200.
In this embodiment, the network configuration request may further include an address of a network configuration agent, and the network configuration agent is configured in thesecond container 300.
Step S320 may also be implemented by:
after receiving the network configuration request, thecontainer engine 400 sends the network configuration request to the network configuration agent of thesecond container 300 according to the destination address in the network configuration request and the address of the network configuration agent, and the network configuration agent performs network configuration on the first container according to the container address and the network configuration information of thefirst container 200.
Specifically, in the embodiment of the present application, the network configuration agent may be implemented in the form of a script. In the above method, a bridge is established between thefirst container 200 and thesecond container 300 by thecontainer engine 400, and the network configuration is performed on thefirst container 200 by thecontainer engine 400 and thesecond container 300, so that the network operating system has a function of configuring its own network in thefirst container 200.
Referring to fig. 4, in the embodiment of the present application, before step S310, the method may further include step S308 and step S309.
Step S308, starting a first container and a second container, and acquiring a container address of the first container and a container address of the second container.
Step S309, sending the container address of the second container to the first container, so that the first container generates the network configuration request, where the network configuration request includes the container address of the first container, the container address of the second container, and the network configuration information obtained through the interface management process of the first container.
In the above process, thecontainer engine 400 first starts thesecond container 300, and obtains the container address of thesecond container 300.
In the embodiment of the present application, a technician may configure a container in advance, so that the container has a network configuration right. Further, a network configuration agent may also be configured in the container such that the network configuration agent has network configuration rights.
Thecontainer engine 400 starts thefirst container 200 after starting thesecond container 300. After the start of thefirst container 200 is completed, the container address of thesecond container 300 is transmitted to thefirst container 200. So that thefirst container 200 generates a network configuration request according to its own container address, the container address of thesecond container 300, and the network configuration information that thefirst container 200 needs to configure.
In the network configuration method provided in the embodiment of the present application, the network configuration information to be configured is obtained by the interface management process in thefirst container 200, and is sent to thesecond container 300, and thesecond container 300 completes the network configuration on thefirst container 200 according to the network configuration information in the network configuration request. The network configuration of the container running the network operating system in the container is realized. Meanwhile, in the above process, when thefirst container 200 has a new network requirement that needs to be configured, the container engine sends the network configuration request to thesecond container 300 again, so as to implement dynamic network configuration on thefirst container 200, and because the container configuration requirement and the configuration time in the configuration process are determined by thefirst container 200, it is ensured that the network requirement that needs to be configured in thefirst container 200 can be configured in time.
The method can solve the problem that the existing container configuration method cannot be suitable for network configuration of the container for realizing the network operating system due to the factors such as the number, the type, the opportunity and the like of configuration interfaces when thecontainer engine 400 is adopted for configuration before the container is opened in the prior art.
