This section outlines new features and enhancements introduced in the Mirantis Container Cloud release 2.1.0. For the list of enhancements in the Cluster release 5.8.0 introduced by the KaaS release 2.1.0, see 5.8.0.
Node labeling for machines¶
Implemented the possibility to assign labels to specific machines with
dedicated system and hardware resources through the Container Cloud web UI.
For example, you can label the StackLight nodes that run Elasticsearch and
require more resources than a standard node to run the StackLight components
services on the dedicated nodes.
You can label a machine before or after it is deployed.
The list of available labels is taken from the current
Node labeling greatly improves cluster performance and prevents pods from being quickly exhausted.
AWS resources discovery in Container Cloud web UI¶
Improved the user experience during a managed cluster creation using the Container Cloud web UI by implementing drop-down menus with available supported values for the following AWS resources:
AWS AMI ID
AWS instance type
To apply the feature to existing deployments, update the IAM policies for AWS as described in Apply updates to the AWS-based management clusters.
