Docker container-based log acquisition method and apparatus

Abstract

The invention provides a Docker container-based log acquisition method and apparatus. The method comprises the steps of receiving a container creation instruction input by a user, wherein the container creation instruction carries identifier information of a host; sending the container creation instruction to the host according to the identifier information of the host to enable the host to create a Docker container, creating a folder corresponding to a container root directory, creating a host root directory and a corresponding target address on the host, and mounting a folder corresponding to the container root directory into the target address corresponding to the host root directory, wherein the container creation instruction carries container folder mounting parameters, and the corresponding target address comprises an identity code of the Docker container; sending a container starting instruction to the host, thereby enabling the Docker container of the host to write generated logs in the folder corresponding to the container root directory in a classified manner; and obtaining a folder corresponding to the Docker container from the target address according to the identity code of the container in the target address, thereby obtaining the logs in the folder.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, and in particular to a method and device for acquiring logs based on a Docker container. Background technique [0002] The container-based virtualization technology represented by Docker is the current hotspot of virtualization technology. Container technology realizes lightweight virtualization by isolating processes and resources. Docker is an open source application container engine that provides a solution for rapid and automated deployment of applications. Using Docker, you can quickly create and start a container using the image where the application is located. After the container is created and running, the application is deployed. Multiple Docker containers can be deployed on a physical machine, and each Docker container is isolated from each other. This physical machine is generally called a host machine. [0003] During the running of the application, a l...
