Patch Management

Patch Management allows users to manage patches on (Elastic Cloud Server) ECS or Cloud Container Engine (CCE) instances by scanning and repairing patches.

Before managing patches, ensure that the OSs of execution machines are supported by the existing patch management feature, and the second-party package depended by the patch management feature is contained in the execution machine and the package functions are normal. Otherwise, patches may fail to be managed.

Table 1 lists the OSs and versions supported by the patch management feature.

Table 2 lists the second-party package on which the patch management feature depends.
