New Features and Capabilities

Apache Mesos 1.5, Marathon 1.6, and Kubernetes 1.9 Integrated.

DC/OS 1.11.0 is is based on Mesos 1.5. View the Mesos changelog.

DC/OS 1.11.0 is integrated with the latest 1.6 release of Marathon. For more information about Marathon 1.6, consult the Marathon changelog.

DC/OS 1.11.0 supports the latest Kubernetes 1.9 Container Scheduler. For more information about Kubernetes 1.0 on DC/OS, view the documentation.

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 a cluster and another cluster. 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.

UCR Support for Docker image garbage collection. View the documentation. Support for Docker image pull secrets.



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 . Please read this note to learn more about the re-factoring of the network stack.

. Please 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 Binary Secret files are now supported Hierarchical access control is now supported.



Monitoring

The DC/OS metrics component now produces metrics in Prometheus format. View the documentation.

Unified logging API that provides simple access to container (task) as well as 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. 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. Beta features are not recommended for production usage, but are a good indication of the direction the project is headed.

TLS encryption for DC/OS Kafka, DC/OS Cassandra, DC/OS Elastic, and DC/OS HDFS is now supported.

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.

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.
