* Container mount namespace encapsulation and kdump are now available in the {rds} RDS.
|
|
|
|
Description::
|
|
* Container mount namespace encapsulation creates a container mount namespace that reduces system mount scanning and is visible to kubelet and CRI-O.
|
|
* kdump is an optional configuration that is enabled by default that captures debug information when a kernel panic occurs.
|
|
The reference CRs which enable kdump include an increased memory reservation based on the set of drivers and kernel modules included in the reference configuration.
|
|
|
|
Limits and requirements::
|
|
* Use of kdump and container mount namespace encapsulation is made available through additional kernel modules.
|
|
You should analyze these modules to determine impact on CPU load, system performance, and ability to meet required KPIs.
|
|
|
|
Engineering considerations::
|
|
* Install the following kernel modules with `MachineConfig` CRs.
|
|
These modules provide extended kernel functionality to cloud-native functions (CNFs).
