Embodiment Construction
[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0045] The LXC technology in the Docker architecture is a lightweight virtualization technology. Its principle is that the kernel of the operating system provides different system views for different running processes. This isolation can be used to authorize access to hardware resources while maintaining security and efficiency. At present, LXC is isolated by using the kernel namespace (namespace), that is to say, multiple LXCs still share a kernel. Co...

The invention discloses a container access method and device. The method comprises the following steps of: receiving a container access request, wherein the container access request is used for requesting to access a target container; selecting a driving instance corresponding to the target container from a plurality of currently running driving instances, wherein different driving instances in the plurality of driving instances are used for driving different types of containers, and the plurality of driving instances are managed through a same program; and sending the container access requestto the driving instance corresponding to the target container. According to the method and device, the driving instances for driving different types of containers are managed through one program, andusers can access a plurality of different types of containers through the program, so that the condition of managing different driving instances through different programs so as to access different types of containers in the prior art is avoided, and the operation overhead of the program for managing a plurality of driving instances in a container engine is decreased.
Description
technical field [0001] The embodiments of the present invention relate to the computer field, and in particular, to a method and device for accessing a container. Background technique [0002] The container engine can be used to manage containers, and users can run multiple types of containers through a single container engine, such as Linux containers and container virtual machines. However, when managing multiple different types of containers through a container engine, different programs need to be used to manage the driver instances used to drive different types of containers. At this time, the management in the container engine will be added to drive different types of containers. The running overhead of the program that drives the instance. The following takes the container engine Docker as an example to introduce it in detail. [0003] Docker is an open source container engine designed to provide an automated deployment solution for applications. Based on Linux con...
