Chronos 2.3.3 released

For more than five years, DC/OS has enabled some of the largest, most sophisticated enterprises in the world to achieve unparalleled levels of efficiency, reliability, and scalability from their IT infrastructure. But now it is time to pass the torch to a new generation of technology: the D2iQ Kubernetes Platform (DKP). Why? Kubernetes has now achieved a level of capability that only DC/OS could formerly provide and is now evolving and improving far faster (as is true of its supporting ecosystem). That’s why we have chosen to sunset DC/OS, with an end-of-life date of October 31, 2021. With DKP, our customers get the same benefits provided by DC/OS and more, as well as access to the most impressive pace of innovation the technology world has ever seen. This was not an easy decision to make, but we are dedicated to enabling our customers to accelerate their digital transformations, so they can increase the velocity and responsiveness of their organizations to an ever-more challenging future. And the best way to do that right now is with DKP.

Scheduling recurring jobs reliably and at scale can be a challenge. In the Apache Mesos ecosystem, we have Chronos, a distributed and fault-tolerant scheduler that allows us to do exactly this.

 

Now, we're proud to announce the availability of Chronos version 2.3.3 that was released on 20 April. This release not only come with a number of bug fixes, as you would expect, but also has some pretty cool new stuff:

 

  • Concerning job history, based on your feedback, we added fields such as start & end time, duration, and whether it finished successfully or failed. We're now also using a second-level resolution. Internally, the history is stored based on the job name and the task ID (instance of the job executed), giving fine-grained access.
  • An improved UI (see also screenshot, below): on top of the already mentioned job history, we now add the following job traits which are configurable: cpu, mem, disk, and priority. Also, we added owner and job description fields to job definition, which should help you when troubleshooting things.
  • Framework authentication: inheriting this property from Apache Mesos, you can learn more about it through the respective section in the docs.
  • Last but not least, in the 2.3.3 release we made sure that we're in sync with latest version of Apache Mesos and Chaos.

Mesosphere partnered with Michael Ngo and Aimee Morgan from Flixster. We would like to thank them as well as the Chronos community for their contributions. Last but not least: Chronos is now fully integrated in the DCOS and you can try it yourself by signing up here.
