Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, the existing service deployment method is easy to cause network congestion, and has the problems of low deployment efficiency, long mirror image pulling time and the like. Based on the above, the implementation of the invention provides a container cluster service deployment method, a device, a server and a storage medium, which can effectively reduce the risk of network congestion, improve the deployment efficiency of service update and remarkably shorten the time of mirror image pulling.
To facilitate understanding of the present embodiment, first, a detailed description is given to a container cluster service deployment method disclosed in the embodiment of the present invention, where a management container and a plurality of service nodes are deployed in a container cluster, and the service nodes are used for operating a service controller, where the method is applied to the management container, referring to a flowchart of a container cluster service deployment method shown in fig. 1, the method mainly includes the following steps S102 to S106:
step S102, obtaining controller information corresponding to at least one service controller. The service controller operates in a service node, the controller information includes mirror image information and node information, the mirror image information at least includes a mirror image identifier (such as a container mirror image tag number), and the node information at least includes a node identifier (such as an Identity Document (ID) or a node name) and a node IP (Internet Protocol Address). In one embodiment, the controller information may be obtained through an Interface management layer, which may be an API server or a container clustering API (Application Programming Interface).
And step S104, determining at least one target service controller with the mirror image to be updated and a target service node to which each target service controller belongs from the service controllers based on the controller information. The target service controller is a service controller of the latest version for the used mirror image. In an embodiment, the service node to which each service controller belongs may be determined according to the node identifier, or the target image version and the target image creation time may be queried according to the image identifier, and whether the service controller has an image to be updated is determined based on the target image version and the target image creation time, and if so, the service controller may be determined as the target service controller, and further, the target service node to which the target service controller belongs may be determined.
Step S106, according to the network condition of each target service node, controlling at least one target service node to pull the mirror image to be updated corresponding to the target service controller, so as to perform service deployment for the target service controller after the mirror image to be updated is pulled. The network conditions include good network conditions and poor network conditions. In an embodiment, a target service node with good network condition may be controlled to pull a mirror image to be updated corresponding to a target service controller running therein, if the number of the target service nodes with good network condition is multiple, a single or multiple target service nodes may be selected to pull the mirror image to be updated corresponding to the target service controller running therein at the same time, and after all the target service nodes finish pulling the mirror image to be updated, an administrator is notified to perform service deployment.
According to the container cluster service deployment method provided by the embodiment of the invention, the management container is deployed in the container cluster, the management container can determine the target service controller needing mirror image updating and the target service node thereof on the basis of the controller information, further inform the target service node to pull the mirror image to be updated, and perform service deployment after all the target service nodes finish the pulling of the mirror image to be updated.
For convenience of understanding, an embodiment of the present invention provides a container cluster service deployment architecture, and referring to a schematic diagram of a container cluster service deployment architecture shown in fig. 2, fig. 2 illustrates that an APIserver, a management pod (i.e., the above management container), a service node, and a pod are deployed in a container cluster. On the basis of the above steps: (1) The management pod acquires controller information of the service controller from the APIserver; (2) The management pod acquires and analyzes the mirror image state of the mirror image warehouse in the current service controller from the mirror image warehouse (also called as a container warehouse), and the mirror image state is used for representing whether the current service controller has a mirror image to be updated or not; (3) The management pod acquires the network condition of the service node where the service controller is located from an external monitoring platform (also called as a node monitoring system); (4) the management pod informs the service node to pull the mirror image to be updated; (5) And the service node pulls the mirror image to be updated from the external management platform.
On the basis of the foregoing embodiment, in order to facilitate understanding of step S102 described above, in an embodiment of the present invention, an implementation is provided for acquiring controller information corresponding to at least one service controller, where the management pod may send an information acquisition request to an interface management layer of the container cluster, so that the interface management layer feeds back the controller information corresponding to the at least one service controller for the information acquisition request, and the management pod receives the controller information fed back by the interface management layer. In specific implementation, the management pod sends an information acquisition request to the apicerver to request all service controller names, so as to analyze which service nodes the service controller target operates on, the tag number of the used container image, the current image creation time and the like. Wherein, part of the controller information is obtained by filtering the returned result of the APIserver. The embodiment of the invention can separate the management pod from the service controller by requesting the controller information from the APIserver, and does not have any invasion to the service code and the architecture.
In one embodiment, the controller information spec includes mirror information of contacts and actual node information (which may also be referred to as pod information), for example, referring to a schematic diagram of mirror information shown in fig. 3 and a schematic diagram of node information shown in fig. 4, fig. 3 illustrates that the mirror information may include "image:192.168.5.122/robot-quality-report; test _ v1.0.1.X ", the node information may include" message: regenerative "robot-port-deployment-f 9b88d74c" has leisure treated ". It should be noted that the mirror information and the node information described above are merely examples.
On the basis of the foregoing embodiment, to facilitate understanding of step S104, an embodiment of the present invention provides an implementation manner for determining, based on the controller information, that there are at least one target service controller of the mirror to be updated and a target service node to which each target service controller belongs from the service controllers, and specifically refer to steps 1 to 3 as follows:
And 2, judging whether the service controller has a mirror image to be updated according to the target mirror image version and the target mirror image creation time. In an embodiment, whether the service controller has an image to be updated may be determined according to the following steps 2.1 to 2.2:
and 2.1, acquiring a current mirror image version and current mirror image creation time corresponding to the service controller. In another embodiment, a container engine on a service node where the service controller is located may be used to query, according to an image identifier, an image creation time of an image currently used by the service controller, for example, see another schematic diagram of image information shown in fig. 6, where fig. 6 illustrates that the current image creation time corresponding to the image identifier after the container engine queries is "Created:2021-04-14T10:04:36.021237024Z ".
And 2.2, if the target mirror image version is larger than the current mirror image version and the target mirror image creation time is later than the current mirror image creation time, determining that the service controller has a mirror image to be updated. The target image version may be recorded as a target image tag number, and the current image version may be recorded as a current image tag number. In specific implementation, when the target mirror image tag number of the mirror image is greater than the current mirror image tag number currently used by the service controller, and the target mirror image creation time is later than the target mirror image creation time currently used by the service controller, it may be determined that the mirror image of the service controller has the latest version, and the management pod obtains the latest mirror image version. Exemplarily, referring to a schematic diagram of a mirror image sample shown in fig. 7, fig. 7 illustrates a mirror image tag number and a mirror image creation time, and may further display a push time of the mirror image.
And 3, if so, determining the service controller as a target service controller, and determining a service node to which the service controller belongs as a target service node.
On the basis of the foregoing embodiment, to facilitate understanding of step S106, an embodiment of the present invention provides an implementation that controls at least one target service node to pull a mirror image to be updated corresponding to a target service controller according to a network condition of each target service node, where reference is made to the following steps a to d:
step a, for each target service node, sending the node identifier of the target service node to a node monitoring system, so that the node monitoring system queries the network traffic of the target service node. Wherein, the node monitoring system can adopt a conventional monitoring system zabbix or prometheus. In one embodiment, the node monitoring system may be requested to query the current network traffic of the target service node, such as a node network traffic diagram shown in fig. 8, where fig. 8 is for reference only and is not actual data. In specific implementation, the network traffic of the target service node may be queried in the form of an API interface, and the query condition is the IP address of the target service node.
And b, receiving the network flow fed back by the node monitoring system, and determining the network condition of the target service node according to the network flow. In one embodiment, if the network traffic is below a specified usage threshold, it may be determined that the network is in good condition; otherwise, if the network traffic is above the specified utilization threshold, a poor network condition may be determined. Wherein the specified usage threshold may be adjusted based on actual conditions. For example, if the usage threshold is 80%, it may be determined that the network condition is good when the usage is lower than 80%, and it may be determined that the network condition is bad when the usage is higher than 80%.
And c, if the network condition is that a plurality of target service nodes with good network condition exist, controlling at least one target service node to pull the mirror image to be updated corresponding to the target service controller. In one embodiment, after determining the target service node with good network conditions, the management pod transmits the target image version to the container engine of the target service node with good network conditions, and the container engine initiates a request for pulling the latest image to the container warehouse. Optionally, if there are multiple target service nodes with good network conditions, the management pod may control operation of one or multiple target service nodes according to the network conditions of the target service nodes, and finally all the service nodes complete pulling of the latest mirror image version.
In a specific implementation, the mirror image pull manner is an operation instruction (such as a pull command) of the container engine, such as a schematic diagram of an operation instruction shown in fig. 9, the container engine only needs a mirror image address to pull the mirror image of the target mirror image version, the container engine pulls the basic function built in the function bit container engine, and the operation instruction is issued to the container engine by the management pod and executed by the container engine/the background.
And d, if the network condition of the target service node is poor, sending the node identifier of the target service node to a node monitoring system according to a preset period until the network condition of the target service node is good. In one embodiment, in case of a bad network condition, the management pod will suspend for a period of time and then repeatedly initiate the request, and continuously monitor the network condition of the target service node until the network condition is good. In specific implementation, the restart initiation request is an analysis time period, the requirement on timeliness of the task is not high, and when the current network state is monitored to be poor, judgment is continued in the next period until the network condition is good. Optionally, if the network conditions are consistent and the network conditions are not good, the mirror image will not be pulled, so as to avoid causing network stress.
In one embodiment, after each target service node finishes pulling the mirror image to be updated, the target service node, the target mirror image version corresponding to the mirror image to be updated and the pulling duration are sent to the instruction association terminal. In another embodiment, after each target service node finishes the pulling of the mirror image to be updated, a mirror image pulling log is generated based on the target service node, the target mirror image version corresponding to the mirror image to be updated and the pulling time length, and the mirror image pulling log is stored in the specified storage area. In practical application, after all the service nodes finish the pulling of the latest mirror image, the information of the operated service nodes, the latest mirror image version number, the consumed time and the like is transmitted to an administrator or stored in a log so as to express that the pulling of the current latest version mirror image is finished to the administrator, and the service updating can be started. At this time, the administrator starts to update the service, and since the node already contains the latest mirror version, the pull time is extreme or zero. The whole process is finished, and the subsequent whole process enters a circulating state.
To facilitate understanding of the foregoing embodiments, an application example of a container cluster service deployment method is provided in the embodiments of the present invention, referring to a flow diagram of another container cluster service deployment method shown in fig. 10, where the method mainly includes the following steps S1002 to S1010:
step S1002, a management pod is deployed in the service name middle where the container cluster belongs.
Step S1004, the management POD requests the container warehouse for a query of the target image version and the target image creation time.
Step S1006, analyzes the network status of the target service node to which the target service controller belongs.
Step S1008, the target service node with good network condition is controlled to pull the mirror image of the target mirror image version.
In step S1010, the management pod returns the mirror pull result, and step S1004 is executed.
In summary, the container cluster service deployment method provided in the embodiments of the present invention can reduce the risk of network traffic congestion, improve the deployment efficiency of service update, and reduce the mirror image pull time to an extreme value or a zero value.
