For example, assume that the current service includes 5 service nodes, where the version corresponding to 3 service nodes is version a, and the version corresponding to 2 service nodes is version B, then the target version is version a.
Optionally, after creating the container according to the number of the service nodes, the method further includes the following steps: and registering the created container in the service master node.
The method for registering the created container in the service master node may be as follows: acquiring an identity identification code (ID) of the created container; and adding the ID of the created container to a monitoring table of the service master node.
In this embodiment, the created container is registered in the master control node, so that the master control node monitors the newly added container in real time.
And step 140, performing publishing operation on the created container according to the target version.
The method for performing publishing operation on the created container according to the target version may be as follows: acquiring an application program corresponding to a target version; and loading the application program into the created container.
