Apache Mesos 1.4.0 Released

The latest Mesos release, 1.4.0, is now available for download. This release includes the following features and improvements:

  • MESOS-5116 - The disk/xfs isolator now supports the --enforce_container_disk_quota flag to efficiently measure disk usage without enforcing usage constraints. The previous implementation always enforced the quota even if the operator might not have wanted it.

  • MESOS-6223 - With partition awareness, the agents are now allowed to re-register after they have been marked Unreachable. Thus, they can recover their agent ID after a host reboot. See docs/upgrades.md for details.

  • MESOS-6375 - Experimental Support for hierarchical resource allocation roles. Hierarchical roles allows delegation of resource allocation policies (i.e. fair sharing and quota) further down the hierarchy. For example, the “engineering” organization gets a 75% share of the resources, but it’s up to the operators within the “engineering” organization to figure out how to fairly share between the “engineering/backend” team and the “engineering/frontend” team. The same delegation applies for quota. NOTE: There are known issues related to hierarchical roles (e.g. hierarchical quota allocation is not implemented and quota will be over-allocated if used with hierarchical roles, see: MESOS-7402) and thus it is not recommended for production usage at this time.

  • MESOS-7418, MESOS-7088 - File-based secrets are now supported for Mesos and Universal containerizer. A new SecretResolver module kind is introduced to fetch and resolve any secrets before they are made available to the tasks. Image-pull secrets are also supported for Docker registry credentials.

  • MESOS-7477 - Linux ambient capabilites are now supported, so frameworks can run tasks that use ambient capabilites to grant limited additional privileged to tasks without the requirement for matching file-based capabilities.

  • MESOS-7476, MESOS-7671 - Support for frameworks and operators specifying Linux bounding capabilities in order to limit the maximum privileges that a task may acquire.

More than 200 other bug fixes and improvements made it into this release. For full release notes with all features and bug fixes, please refer to the CHANGELOG.
