    • Uninstall the existing CLI.
    • Install version 0.5.3 using the Install CLI instructions in the dropdown in the upper left hand corner of the 1.10 DC/OS GUI.
  • You must upgrade Marathon-LB before upgrading to DC/OS 1.10. See the upgrade section for more information.
    • Note: CLI version 0.5.3 is not compatible with DC/OS 1.9.

Please try out the new features and updated data services. Provide any feedback through Jira: https://jira.dcos.io.

DC/OS 1.10 includes many new capabilities for Operators and expands the collection of Data & Developer Services with a focus on:

  • Core DC/OS Service Continuity - System resilience, cluster and node checks, UCR and Pods improvements.
  • CNI Networking enhancements for broader networking support.
  • Data Services enhancements.

New Features and Capabilities

Apache Mesos 1.4 and Marathon 1.5 Integrated.

  • DC/OS 1.10 is is based on Mesos 1.4.0, here using master branch (pre-release) SHA 013f7e21, with over 1200 commits since the previous Mesos version. View the changelog.

  • DC/OS 1.10 is integrated with the latest release of Marathon, version 1.5. Resulting breaking changes and new features are documented below. For more information about Marathon 1.5, consult the Marathon changelog.

Networking

  • Configurable Spartan upstreams for domains (dnames). You can now configure Spartan to delegate a particular domain (e.g. "*.foo.company.com") to a particular upstream.

  • Increased CNI network support. DC/OS now supports any type of CNI network. View the documentation.

Platform

  • Node and Cluster health checks. Write your own custom health checks or use the predefined checks to access and use information about your cluster, including available ports, Mesos agent status, and IP detect script validation. View the documentation.
  • Enhanced upgrades with pre/post flight checks.
  • UCR.
  • Scale and performance limits.

CLI

GUI

The GUI sidebar tabs have been updated to offer a more intuitive experience.

  • The "Deployments" subpage under the "Services" tab has been moved to a toggle-able modal in the "Services" page.
  • The "Universe" tab has been renamed to "Catalog" and the "Installed" subpage has been removed.
  • The "System Overview" tab has been renamed to "Overview".

Updated DC/OS Data Services

  • Rolling Configuration Update and Upgrades support via CLI.
  • Ability to deploy Data Services into Folders to enable multi team deployments.
  • Ability to deploy to CNI-Based Virtual Networks.

The following updated data services packages are also in beta and are compatible with DC/OS 1.10.

Breaking Changes

  • Upgrades not supported from 1.10.0 Beta 1 to 1.10.0 Beta 2. Upgrades from 1.10.0 Beta 1 to 1.10.0 Beta 2 are not supported in 1.10.0 Beta 2. This upgrade will be supported in a future 1.10 release.

  • Marathon Networking API Changes in 1.5 The networking section of the Marathon API has changed significantly in version 1.5. Marathon can still accept requests using the 1.4 version of the API, but it will always reply with the 1.5 version of the app definition. This will break tools that consume networking-related fields of the service definition. View the documentation.

  • The latest version of Marathon-LB is required for 1.10. Before upgrading to 1.10, uninstall your existing Marathon-LB package and reinstall the updated version. See the upgrade section for more information.

  • REX-Ray configuration change. DC/OS 1.10 upgrades REX-Ray from v03.3. to v0.9.0 and therefore the REX-Ray configuration format has changed. If you have specified custom REX-Ray configuration in the REX-Ray_config parameter of your config.yaml file, change the parameter to REX-Ray_config_preset: aws.

  • New flow to change the dcos_url and login. The new command to change your cluster URL is dcos cluster setup <dcos_url>. This change will break any existing tooling that uses the former command. Backwards compatibility is slated for a future patch release.
