Fig. 1 is a schematic structural diagram of an application package deployment system based on a K8s cluster, which includes a K8s management cluster 1 and at least one K8s managed cluster 2. Fig. 1 is a schematic diagram illustrating 1 managed cluster 2 of K8s as an example, and in the embodiment of the present invention, the number of the managed clusters 2 of K8s is not limited.
The application package management server 11 for storing the application package file is deployed in the K8s management cluster 1, and the initialization container 21 and the application container 22 are deployed in each K8s managed cluster 2; the initialization container 21 shares the same storage space as the application container 22.
In an embodiment of the present invention, one K8s managing cluster 1 may provide an application package file to multiple K8s managed clusters 2 at the same time. Each K8s managed cluster 2 implements containerized deployment of application packages in a similar manner, and in the following description, a K8s managed cluster 2 is used as an example for description.
The initialization container 21 and the application container 22 are provided in the managed cluster 2 at K8s, depending on the task to be performed. The initialization container 21 is a container in the pod of K8s that is dedicated to initialization, and the initialization container 21 can be used to acquire the application package file.
In a specific implementation, the initialization container 21 may obtain the application package file from the application package management server 11 according to the address information of the application package management server 11, and store the application package file.
The initialization container 21 may store the acquired application package file in a mounted path thereof, and the initialization container 21 and the application container 22 share the same storage space, so that the application container 22 can acquire the application package file according to a data reading path.
The application container 22 may copy the application package file to the working path of the application server, and initiate the application server to decompress and deploy the application package file.
In the embodiment of the invention, the storage volume can be adopted to store the application package file, and the storage volume can realize the persistent storage of the application package file.
Taking K8s as an example for managing the cluster 1, a first storage volume for storing an application package file may be mounted on the application package management server 11.
The first storage volume may be predefined by a user, the user may input a storage volume creation instruction to the server of the K8s management cluster 1, and the K8s management cluster 1 predefines a storage volume according to the received storage volume creation instruction and mounts the storage volume as the first storage volume on the application package management server 11.
In practical applications, the application package management server 11 may employ a File Transfer Protocol (FTP) server.
Taking K8s as an example for managed cluster 2, initialization container 21 and application container 22 may mount a second storage volume.
Similarly to the manner of creating the first storage volume, the second storage volume may be predefined by a user, the user may input a storage volume creation instruction to the server of the K8s managed cluster 2, and the K8s managed cluster 2 may predefine a storage volume according to the received storage volume creation instruction, and mount the storage volume as the second storage volume on the initialization container 21 and the application container 22, respectively.
Accordingly, after acquiring the application package file from the application package management server 11, the initialization container 21 may store the application package file in a path of being mounted on the second storage volume; the application container 22 may obtain the application package file according to the path mounted on the second storage volume.
In the embodiment of the present invention, the initialization container 21 and the application container 22 both mount the same storage volume, and after the initialization container 21 is started, the uploaded application package file is obtained from the FTP service deployed in the cluster where the K8s management software is located, that is, the K8s management cluster 1, in an FTP manner, and is stored in the path mounted in the initialization container 21. Then, the application container 22 is started, and since the initialization container 21 and the application container 22 mount the same storage volume, the application package file stored in the initialization container 21 can be seen in the path where the application container 22 mounts the storage volume. The application container 22 copies the application package file to the working path of the application server, and then starts the application server, at this time, the application server will automatically decompress and deploy the application package file in the working path, so that the application server can provide the service provided by the application package file after starting.
In the embodiment of the present invention, after the K8s is completed by the application server of the management cluster 2 to decompress and deploy the application package file, the second storage volume may be released in order to reduce the occupation of the storage resource.
According to the technical scheme, the application package deployment system based on the K8s cluster comprises a K8s management cluster and at least one K8s managed cluster; the K8s management cluster is provided with an application package management server for storing application package files, and each K8s managed cluster is provided with an initialization container and an application container. One container can only execute one task, and the managed cluster deploys an initialization container at K8s to realize the interaction with the application package management server; the managed cluster deploys the application container at K8s, enabling interaction with the application servers. The initialization container may obtain the application package file from the application package management server according to the address information of the application package management server, and store the application package file. Because the initialization container and the application container share the same storage space, the application container can acquire the application package file from the storage space according to the corresponding data reading path, copy the application package file to the working path of the application server, and start the application server to decompress and deploy the application package file.
