s101, receiving an application program upgrading request sent by an operation and maintenance terminal.

The application program upgrading request comprises current application program information and target application program information. The current application information refers to the relevant information of the application program currently operated by the container, and the target application information refers to the relevant information of the application program operated after the container is upgraded.

In particular, the current application information may include a current application identification, current application identification version information. The target application information may include a target application identification, target application identification version information.

For example, if the current application id of the current application information is 001 and the current application id version information is V1.0.0, the application id of the matching test application is also 001 and the application id version information is also V1.0.0.

In some embodiments of the present application, several containers may be pre-constructed, which may not be open to the user, and exist only as a test, i.e., the test container described above. Or, selecting several application containers from the application containers to be upgraded according to a preset rule as test containers, where the application rule may be that a container with a smaller user access amount is selected as a test container according to the user access amount.
