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

CAUTION:

Currently, patch management supports only servers that can access the public network. You can bind an EIP or NAT gateway to implement patch management.

NOTE:

Before managing patches, ensure that the regions where the execution machines are deployed and the operating systems (OSs) of the execution machines are supported by the existing patch management feature, and the second-party package, on which the patch management feature is dependent on, 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 environment on which patch management depends.
