Detailed Description
The core of the invention is to provide a method, a system and a device for monitoring a container cluster, when a cloud management platform accesses a new container cluster each time, the method and the system can automatically install monitoring components for nodes corresponding to the new container cluster, thereby improving the operation and maintenance efficiency of the node container.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, 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.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for monitoring a container cluster according to an embodiment of the present invention.
The monitoring method of the container cluster is applied to a cloud management platform and comprises the following steps:
step S1: and when a new container cluster is accessed, automatically scanning node information of all nodes corresponding to the new container cluster.
Specifically, the container cluster accessed by the cloud management platform is composed of containers deployed on a plurality of nodes in the k8s container management platform. Since the containers owned by the same node in the k8s container management platform correspond to the same k8s network, the containers owned by the same node can interact with each other. The k8s networks corresponding to different nodes are independent from each other, so that containers deployed on different nodes cannot interact with each other.
Based on this, when monitoring the container cluster, a monitoring component needs to be installed on each node corresponding to the container cluster, and the monitoring component is equivalent to a container deployed on the node and can interact with the originally deployed container on the node to realize container monitoring. Therefore, when the cloud management platform is accessed to the new container cluster, the node information of all the nodes corresponding to the new container cluster can be automatically scanned, and the node information is stored in the database of the cloud management platform, so that a foundation is laid for subsequently judging whether the monitoring component is installed on the node or not.
Step S2: judging whether a monitoring component is installed on the target node or not according to the node information of the target node; if not, step S3 is executed.
Note that the target node in step S2 is any one of all the nodes in step S1.
Specifically, the node information of the target node includes the relevant information of whether the monitoring component is installed on the target node, so that the application can judge whether the monitoring component is installed on the target node according to the node information of the target node. If the target node is provided with the monitoring component, the monitoring component does not need to be installed for the target node, and the existing monitoring component on the target node is directly used for monitoring the belonged container on the target node; if the monitoring component is not installed on the target node, the monitoring component needs to be installed on the target node, and then the monitoring component installed on the monitoring component is used for monitoring the container belonging to the target node.
Step S3: and automatically installing a monitoring component for the target node so as to monitor the container deployed on the target node by using the monitoring component.
Specifically, when it is determined in step S2 that the monitoring component is not installed on the target node, the monitoring component may be automatically installed on the target node, and specifically, the monitoring component may be automatically installed in the target node through a hell tool. Helm is a software package management tool in the k8s ecosystem, and can package, distribute, install, upgrade and rollback k8s applications by using Helm.
The invention provides a monitoring method of a container cluster, which is applied to a cloud management platform. When a new container cluster is accessed, the node information of all nodes corresponding to the new container cluster can be automatically scanned, whether a monitoring component is installed on each node or not is judged according to the node information, if the monitoring component is not installed on each node, the monitoring component is automatically installed on each node, and therefore node container monitoring is achieved through the monitoring component. Therefore, when the cloud management platform is accessed into the new container cluster every time, the monitoring component can be automatically installed on the node corresponding to the new container cluster, and therefore operation and maintenance efficiency of the node container is improved.
On the basis of the above-described embodiment:
as an alternative embodiment, the node information includes the container names of all containers deployed on the node.
Specifically, all containers deployed on the node have their own exclusive container names, and based on this, the node information of the present application includes the container names of all containers deployed on the node.
As an optional embodiment, the process of determining whether the monitoring component is installed on the target node according to the node information of the target node includes:
judging whether the container name corresponding to the target node contains the name of the monitoring component or not;
if so, determining that the target node is provided with the monitoring component;
and if not, determining that the monitoring component is not installed on the target node.
Specifically, the monitoring component installed on the target node also belongs to the container deployed on the target node, so if the monitoring component is installed on the target node, the node information of the target node obtained by scanning in step S1 includes the name of the monitoring component; if the monitoring component is not installed on the target node, the node information of the target node obtained by scanning in step S1 does not include the name of the monitoring component.
Based on this, the method and the device for monitoring the container name of the target node judge whether the monitoring component is installed on the target node, and specifically judge whether the container name corresponding to the target node contains the name of the monitoring component. If the container name corresponding to the target node contains the name of the monitoring component, determining that the monitoring component is installed on the target node, and not needing to install the monitoring component for the target node; and if the container name corresponding to the target node does not contain the name of the monitoring component, determining that the monitoring component is not installed on the target node, and executing a step of automatically installing the monitoring component for the target node.
As an alternative embodiment, a process for monitoring a container deployed on a target node by using a monitoring component includes:
acquiring the resource utilization rate of a container deployed on a target node by using a monitoring component;
judging whether the resource utilization rate of the target container is greater than a preset alarm threshold corresponding to the target container; wherein the target container is any one of the containers;
if yes, generating corresponding alarm information for alarming.
Specifically, after the monitoring component is installed, the monitoring component can be automatically utilized to acquire the resource utilization rate of the container deployed on the target node, and if the container deployed on the target node includes a Central Processing Unit (CPU), a memory, and an Input/Output (IO) interface, the monitoring component can be automatically utilized to acquire the utilization rate of the CPU, the utilization rate of the memory, and an IO flow.
In consideration of the fact that when the resource utilization rate of the container is too high, the overall operation performance of the container is affected, according to the resource type of the container, warning thresholds are set for the container one by one in advance, and after the resource utilization rate of the target container is collected, whether the resource utilization rate of the target container is larger than the warning threshold corresponding to the target container is judged. If the resource utilization rate of the target container is greater than the alarm threshold value corresponding to the target container, generating corresponding alarm information for alarming, so that operation and maintenance personnel can know that the resource utilization rate of the target container is too high according to the alarm information; and if the resource utilization rate of the target container is not greater than the alarm threshold corresponding to the target container, not reaching the alarm condition and not performing alarm processing.
For example, the utilization rate of the CPU is slight about 0 to 60%, 60% to 80% is moderate, and more than 80% is severe, the alarm threshold of the CPU can be set to 80% in the present application, and when the utilization rate of the CPU is detected to be more than 80%, the corresponding alarm information is generated to alarm, so that the operation and maintenance personnel can know that the utilization rate of the CPU is too high according to the alarm information.
As an optional embodiment, the monitoring method further includes:
resetting the alarm threshold corresponding to the container according to the resource type of the container;
and correspondingly updating the preset alarm threshold according to the reset alarm threshold.
Further, the preset alarm threshold corresponding to the container is stored in a database of the cloud management platform. According to the method and the device, the alarm threshold corresponding to the container can be reset according to the resource type of the container, and then the preset alarm threshold stored in the database of the cloud management platform is correspondingly updated according to the reset alarm threshold, so that when the resource usage of the container is monitored later, the updated alarm threshold is used for alarm judgment.
As an optional embodiment, the monitoring method further includes:
and after monitoring the target node for a preset time, dynamically predicting the use trend of the containers deployed on the target node according to the acquired resource utilization rate corresponding to the target node.
Further, after the target node is monitored for a period of time, the resource utilization rate of the container deployed on the target node collected by the method reaches a certain data volume. Based on the method and the device, the use trend of the container deployed on the target node can be dynamically predicted according to the acquired resource use rate of the container deployed on the target node, so that operation and maintenance personnel can better master the resource use condition of the container in the node.

The judging module 2 can judge whether the monitoring component is installed on the target node according to the node information of the target node. If the target node is provided with the monitoring component, the monitoring component does not need to be installed for the target node; if the monitoring component is not installed on the target node, the module 3 needs to be installed to install the monitoring component for the target node.
When the judging module 2 judges that the monitoring component is not installed on the target node, the installing module 3 can automatically install the monitoring component for the target node, and particularly can automatically install the monitoring component in the target node through a Helm tool. After the installation module 3 installs the monitoring component, the monitoring module 4 monitors the container deployed on the target node by using the monitoring component.
As an alternative embodiment, the node information includes the container names of all containers deployed on the node.
Specifically, all containers deployed on the node have their own exclusive container names, and based on this, the node information of the present application includes the container names of all containers deployed on the node.

Specifically, if the target node is installed with the monitoring component, the node information of the target node obtained by scanning by the scanning module 1 includes the name of the monitoring component; if the monitoring component is not installed on the target node, the node information of the target node scanned by the scanning module 1 does not include the name of the monitoring component.
Based on this, the determining module 2 specifically determines whether the container name corresponding to the target node includes the name of the monitoring component. If the container name corresponding to the target node comprises the name of the monitoring component, determining that the monitoring component is installed on the target node; and if the container name corresponding to the target node does not contain the name of the monitoring component, determining that the monitoring component is not installed on the target node.
