• Managing clusters across multiple clouds. Enterprise
• Production Kubernetes-as-a-service.
• Enhanced data security. Enterprise
• Updated data services.

New Features and Capabilities

Platform

• Multi-region management - Enables a DC/OS Cluster to span multiple datacenters, clouds, and remote branches while providing a unified management and control cluster. View the documentation. Enterprise
• Linked clusters - A cluster link is a unidirectional relationship between one cluster and another. You add and remove links from one cluster to another cluster using the DC/OS CLI. Once a link is set up, you can easily switch between clusters using the CLI or UI. View the documentation. Enterprise
• Fault domain awareness - Use fault domain awareness to make your services highly available and to allow for increased capacity when needed. View the documentation. Enterprise
• Decommission node - Support for permanently decommissioning nodes makes it easier to manage “spot” cloud instances, allowing for immediate task rescheduling. View the documentation
• UCR
  • Support for Docker image garbage collection. View the documentation.
  • Support for Docker image pull secrets. View the documentation. An example for Docker credentials is here. Enterprise

Networking

• Edge-LB 1.0. View the documentation. Enterprise
• IPv6 is now supported for Docker containers.
• Performance improvements to the DC/OS network stack - All networking components (minuteman, navstar, spartan) are aggregated into a single systemd unit called dcos-net. Read this note to learn more about the re-factoring of the network stack.
• The configuration parameter dns_forward_zones now takes a list of objects instead of nested lists (DCOS_OSS-1733). View the documentation to understand its usage.

Security Enterprise

• Secrets Management Service
  • Secrets can now be binary files in addition to environment variables.
  • Hierarchical access control is now supported.

Monitoring

• The DC/OS metrics component now produces metrics in Prometheus format. View the documentation.
• Unified logging API provides simple access to container (task) and system component logs. View the documentation.

Storage

• DC/OS Storage Service 0.1 (beta) - DSS users will be able to dynamically create volumes based upon profiles or policies to fine-tune their applications storage requirements. This feature leverages the industry-standard Container Storage Interface (CSI) to streamline the development of storage features in DC/OS by Mesosphere and our community and partner ecosystems. View the documentation.Beta Enterprise
• Pods now support persistent volumes. View the documentation.Beta

Note: Because these storage features are beta in 1.11, they must be explicitly enabled in the config.yaml file when installing DC/OS. Beta features are not recommended for production usage, but are a good indication of the direction the project is headed.

Updated DC/OS Data Services

• TLS encryption for DC/OS Kafka, DC/OS Cassandra, DC/OS Elastic, and DC/OS HDFS is now supported. Enterprise
• Fault domain awareness for DC/OS Kafka, DC/OS Cassandra, DC/OS Elastic and DC/OS HDFS. Use fault domain awareness to make your services highly available and to allow for increased capacity when needed. Enterprise
• New API endpoint to pause a node for DC/OS Kafka, DC/OS Cassandra, DC/OS Elastic, and DC/OS HDFS. Use this endpoint to relaunch a node in an idle command state for debugging purposes.
• New DC/OS Kafka ZooKeeper service. View the documentation.
• You can now select a DC/OS data service version from a dropdown menu in the DC/OS UI.
• Improved scalability for all DC/OS data services.
