Enhancements
This section outlines new features implemented in the Cluster release 17.4.0 that is introduced in the Container Cloud release 2.29.0. For MOSK enhancements, see New features 25.1.
Support for MKE 3.7.19 and MCR 25.0.8
Introduced support for Mirantis Container Runtime (MCR) 25.0.8 and Mirantis Kubernetes Engine (MKE) 3.7.19 that includes Kubernetes 1.27.16.
On existing clusters, MKE and MCR are updated to the latest supported version when you update your managed cluster to the Cluster release 17.4.0.
New password policies for local Linux user accounts
Introduced new password policies for local (Linux) user accounts.
The rules are applied automatically to all cluster nodes during cluster update. Therefore, if you use custom Linux accounts protected by passwords, pay attention to the following rules, as you may be forced to update uncompliant password during login:
Password expiration interval: 365 days
Minimum password length: 14 symbols
Required symbols are capital letters, lower case letters, and digits
At least 2 characters of the new password must not be present in the old password
Maximum identical consecutive characters: 3 (allowed: aaa123, not allowed: aaaa123)
Maximum sequential characters: 3 (allowed: abc1xyz, not allowed: abcd123)
Dictionary check is enabled
You must not reuse old password
After 3 failed password input attempts, the account is disabled for 15 minutes
