[0029] With the continuous development of distributed technology, container technology has been widely used. Container technology includes multiple nodes, and the state of a node is determined by the state of the container contained in the node. There is a state called D state, which means an uninterruptible sleep state. At present, the detection of D state needs to be queried manually through commands. It is impossible to realize automatic detection of D state and node isolation control based on D state.

[0030] Figure 1This is a flowchart of a node control method based on process status provided by an embodiment of the present invention. This embodiment is applicable to the detection of D status in distributed container technology and the node isolation control based on D status. The method can be executed by a node control device based on process status. The node control device based on process status can be implemented in the form of hardware and / or software. The node control device based on process status can be configured in electronic devices such as personal computers and servers. Figure 1 As shown, the method includes:

[0031] Step S101: Acquire a target process in a target state, where the target state is an uninterruptible sleep state.

[0032] The D state is a state of the Linux process, which is called disk sleep in English. The D state is an uninterruptible sleep state that can appear in scenarios such as reading data from the hard disk. A process in the D state can only be awakened by resources, not by signals, and cannot be killed by the "kill -9" command.

[0033] In the embodiment of the present invention, the D state is called the target state, and a target process in the target state is determined from multiple processes running in the node by querying or the like.

[0034] Optionally, obtaining the target process in the target state can be implemented in the following way:

[0035] Acquire process information of multiple processes, wherein the process information includes a process name and a process status; and determine a target process according to the process status and a preset process identifier.

[0036] Process information can be obtained by executing pre-configured script commands and pre-configured command combinations. The command combination includes but is not limited to using the ps command and the top command in combination with the grep command or the awk command to obtain process information of all processes, and according to the preset process identifier, that is, the text identifier of the D state, from the process information, the process whose process status field matches the text identifier of the D state is searched from the queried process information as the target process.

[0037] Among them, the ps command is used to view the status of the process in the current system, and the top command is used to monitor the running status of the system in real time. The grep command is a text search command that can search for text by using regular expressions and output matching lines to the standard output. The awk command is a text processing command that can process data through built-in functions, pattern matching, and operations.

[0038] The above implementation can automatically determine the target process in the target state, such as the target process in the D state, according to the acquired process name and process state, thereby improving the D state recognition efficiency.

[0039] Optionally, the state information of each process in the " / proc" directory, such as statistical information (stat), status information (status), etc., can be directly read, and then the process in the D state can be filtered and queried as the target process. The " / proc" directory stores data such as the kernel running status.

[0040] Optionally, before obtaining the target process in the target state, the following is further included:

[0041] A configuration file adapted for the node problem detector is generated, wherein the configuration file is used to record relevant parameters of the plug-in operation.

[0042] Accordingly, obtaining a target process in a target state and determining a target object according to a parent process of the target process include:

[0043] A plug-in is created in the node problem detector, and the plug-in is used to obtain a target process in a target state, where the target state is an uninterruptible sleep state; and a target object is determined according to a parent process of the target process.

[0044] Optionally, the configuration file can be a .json file. The category of the plug-in can be a custom plug-in type (custom). Add custom plug-in custom related parameters, such as the interval time for executing the test is 60s, and the response timeout time for executing the test is 10s (that is, if no result is returned within 10s, the unknown status will be reported). You also need to add the path of the relevant execution script and the timeout time for executing the script. You also need to add two types of detection rules for temporary problems and detection rules for permanent problems, namely the target state event Event and the target node state information Node condition.

[0045] Figure 2 A schematic diagram of an architecture for implementing D state detection and isolation based on k8s provided in an embodiment of the present invention.

[0046] Kubernetes (k8s) is a container scheduling management platform, including a management end and multiple host nodes, and the host node can carry containers with different functions. K8s has a node problem detector (Node-problem-detector, NPD), which is a tool for k8s node diagnosis. It can convert the abnormal and sub-healthy status of the node into the event of the Node, and realize the closed loop of node event alarm in combination with Kube-eventer. It is currently running as a plug-in of k8s, and a daemonset (Daemonset) for detecting abnormal indicators is run on each node. In an embodiment of the present invention, a new plug-in is configured in NPD, which is used to determine whether the host node Node is the target node according to the identified target process, and send the target state detection result to NPD. After receiving the target state detection result, NPD feeds back to the K8s management end. When the management end performs a new pod allocation, it can avoid allocating the pod to the target node, or expel the target container container, target container group pod, target node Node or target container unit docker with the target state (D state) according to the target state detection result. Among them, container is a docker container, which is actually a process. Pod is the smallest deployable computing unit created and managed by k8s, a group of strongly associated Docker containers.

[0047] The above implementation can identify the target node in the form of a node problem detector plug-in. The node problem detector is used to achieve isolation control of the node. In the k8s system, the existing node problem detector is used to achieve rapid transmission of the target node identification result and efficient control of the target node, thereby improving the node control efficiency.

[0048] Step S102: Determine the target object according to the parent process of the target process.

[0049] First, a process is created in the host node, also known as process zero. This process zero creates multiple child processes in turn according to demand. Each child process can continue to create its own child process according to demand. And so on, multiple processes are created in the host node. Except for process zero, any process has a parent process. The parent-child process represents the calling relationship between processes.

[0050] Optionally, the process information further includes parent process information; accordingly, determining the target object according to the parent process of the target process includes:

[0051] Determine control group information according to the parent process information of the target process, determine a target container, a target container group and a target node having the target process according to the control group information. Alternatively, obtain startup information layer by layer according to the parent process of the target process; and determine a target container unit according to the startup information and a preset matching character.

[0052] The process information of all processes in the host node can be queried through the command combination. The process information has a field for storing parent process information.

[0053] After obtaining the parent process information, different target object determination methods can be selected according to different situations, and accordingly, the determined target objects are different.

[0054] Exemplarily, the process ID (ppid) of the parent process is determined as the parent process information according to the process ID of the target process. Then, the control group information cgroup information under the parent process ID is obtained through the process ID ppid of the parent process. The target container container id or the target container group pod id containing the D state process can be obtained by filtering text, and the target container container id, the target container group pod id and the target node Node node information are output. Optionally, the above parent process can be the node's process number zero.

[0055] Exemplarily, the parent process (ppid) of the D-state process can be queried by executing the ps and grep commands through the process ID of the target process in the D state. The startup information (cmdline) is filtered and queried according to the preset matching character "docker". If the preset matching character is not in the startup information, the cmdline of the parent process of ppid is continuously searched until the preset matching character "docker" is found, and the characters after the preset matching character are the ID information of the target container docker.

[0056] The above implementations can accurately determine different types of target objects, such as target containers, target container groups, target nodes or target container units, in different ways, thereby automatically identifying different target objects and improving target object identification efficiency.

[0057] Exemplarily, assuming that step S101 and step S102 are performed in the form of a plug-in, the plug-in operation process is as follows:

[0058] Step 1. Execute the script command to filter the process number (pid) of the target process in D state on the Node node.

[0059] Step 2. If the process number (pid) of the target process is empty, the script return value is 0, and the corresponding node status information condition is an error false state;

[0060] Step 3. If the process ID of the target process is not empty, obtain the parent process (ppid) of the process ID, and then obtain the control group information cgroup under the process ID through the process ID ppid of the parent process. The container id or pod id containing the D state process can be obtained by filtering text, and the container id, pod id and Node node information are output. The script return value is 1, and the corresponding condition is correct true state.

[0061] The above implementation can realize real-time monitoring of the D state process on the node, and report it to the k8s upper management component API server, and then isolate the node to prevent Pod from being scheduled to the node. When an abnormality is detected, the detector will report the problem to the API server in the form of Event and Node Condition. When an abnormality is detected, the detector will report the problem to the API server in the form of Event and Node Condition.

[0062] Step S103: performing isolation control according to the target node where the target object is located.

[0063] Optionally, performing isolation control according to the target node where the target object is located includes:

[0064] The plug-in is also used to send target status detection results to the node problem detector so that the node problem detector can isolate and control the target node according to the received detection results. The detection results include target node status information or target status events. The target node status information indicates that the target object in the target node is continuously in the target state within a preset time, and the target state time indicates that the target object in the target node detects the target state.

[0065] When the plug-in detects that the target object in the node is in the target state, the plug-in can send a target state detection result to the node problem detector. The target state detection result includes a target state event, which is used to indicate that the target object is detected to be in the target state at a certain moment.

[0066] The plug-in may also send a target state detection result to the node problem detector when continuously detecting that the target object in the target node is in the target state. The target state detection result includes target node state information, which indicates that the target object is continuously in the target state.

[0067] Optionally, the plug-in can perform detection of target nodes only according to a preset frequency and delay. The node problem detector generates target node status information or target status events according to the detection results according to the configuration file.

[0068] The target status event can be sent by the node problem detector to the application interface service APIservice in the k8s control end for subsequent processing.

[0069] The above implementation method can detect the target node by means of target node status information or target status events and feed back to the node problem detector, thereby detecting the target node in multiple forms and improving ease of use.

[0070] Optionally, the node problem detector performs isolation control on the target node according to the received detection result, which can be implemented in the following manner:

[0071] The node problem detector determines the taint mark of the target node according to the target state detection result; and performs isolation control on the target node according to the taint mark.

[0072] The above implementation method can realize the control of nodes according to the taint mark, especially in the k8s scenario, with the help of the taint mark provided by k8s, the precise isolation control of nodes can be realized, thereby improving the node isolation efficiency.

[0073] Optionally, the node problem detector determines the taint mark of the target node according to the target state detection result, which can be implemented in the following manner:

[0074] The node problem detector determines the target mark that matches the target object number according to the number of target objects contained in the target node and multiple preset mark intervals, and determines the stain mark of the target node according to the target mark.

[0075] Three preset marking intervals can be configured, corresponding to three levels of taint marking. Optionally, the taint marking can be NoSchedule, PreferNoSchedule, NoExecute. The more target objects there are in the target node, the higher the degree of pollution of the target node. Different taint markings can correspond to different node isolation methods.

[0076] The above implementation can accurately determine the taint mark according to the number of target objects, improve the accuracy of the taint mark, and further improve the accuracy of the isolation control of the target node.

[0077] The node control method based on process state provided by the embodiment of the present invention obtains a target process in a target state, wherein the target state is an uninterruptible sleep state; determines a target object according to the parent process of the target process; and performs isolation control according to the target node where the target object is located. Compared with the current need to manually query the target state, the node control method based on process state provided by the embodiment of the present invention can identify the target process in the target state, and after determining the target process, determine the target object that calls the target process according to the parent process of the target process. The target node where the target object is located is isolated and controlled, and the target process in the target state is automatically identified, and the target node is isolated and controlled, thereby improving the target state identification efficiency and node control efficiency.

[0078] Figure 3 1 is a flow chart of a node control method based on process status provided by an embodiment of the present invention, including:

[0079] Step S201: Generate a configuration file adapted for the node problem detector, wherein the configuration file is used to record relevant parameters of the plug-in operation.

[0080] Step S202: create a plug-in in the node problem detector, the plug-in is used to obtain process information of multiple processes, the process information includes process name and process status; determine the target process according to the process status and a preset process identifier; the target state is an uninterruptible sleep state.

[0081] Step S203, determine the control group information according to the parent process information of the target process, and determine the target container, target container group and target node having the target process according to the control group information; or, obtain the startup information layer by layer according to the parent process of the target process; determine the target container unit according to the startup information and preset matching characters, and determine the target object according to the parent process of the target process.

[0082] Step S204: The plug-in is also used to send a target status detection result to the node problem detector.

[0083] The detection result includes target node status information or target status event, wherein the target node status information indicates that the target object in the target node is continuously in the target state within a preset time, and the target state time indicates that the target object in the target node detects the target state.

[0084] Step S205, the node problem detector determines the target mark that matches the target object number according to the number of target objects contained in the target node; determines the stain mark of the target node according to the target mark.

[0085] Step S206: performing isolation control on the target node according to the stain mark.
