Slurm: intense by Kubernetes. Program and bonuses
On May 27-29, we are holding the fourth Slurm: intensive by Kubernetes.
Bonus: online courses on Docker, Ansible, Ceph
We removed topics from Slerma that are important for working with Kubernetes, but do not directly relate to k8s. How, why and what happened - under the cut.
All participants in Slurm-4 will have access to these courses.
Full moneyback on the first day
At the St. Petersburg Slurme two participants left very negative reviews . I regretted that it was impossible to return to the past and part with them without mutual claims.
If you understand that you don’t like at Slurm , write to any of the organizers on the first day . We will disable access and refund the full participation price.
Technical Advice
If anyone knows Dmitry Simonov (he gathered the tech directors club), we invited him to Slurm (to learn, not to perform). He promised to advise everyone. It is unlikely that it will be interesting to administrators and developers, but managers from IT - very much so.

History tour
The first Slurm was an experiment. The speakers finished the presentations literally on the stage, and in the audience were administrators of such a level that it is fitting to invite them to the speakers.
This basic course turned out at the second Slörme: 80% of the participants first saw Cubernets, and a third never worked with Docker.
It was obvious how difficult it is for people to listen to the Docker lecture in the morning, and in the evening to work with him in combat mode.
Ceph caused a lot of difficulties. And there were 20 people in the audience who definitely need to explain Ceph, and another 60 who don't need Ceph at all.
On the third Slurm, we brought Docker and Ansible into separate webinars, freeing up more time for Cooberntes. The solution turned out to be practical in nature and not completed in terms of implementation: the lecture was not interesting for experienced guys, and the discussion was for newcomers.
By the fourth Slerm, we did online courses on Docker, Ansible, and Ceph. The idea is simple: who needs it, thoughtfully passes the course, who does not need it, calmly ignores it. Judging by the group of testers, the Docker course takes 6-8 hours. Ansible and Ceph are not yet timed.
Disclaimer:
- the course is experimental. Some decisions will certainly fail.
- The platform (Stepik.org) is damp and we have not worked with it before. Surely there will be lining and stupid.
- Course tested only on Southbridge employees. Surely you have to finish something on the go.
Only the other day in Chatik the first Slurm recalled how cool and fun it was, despite all the organizational horrors. The first to get the most vivid impressions. Let's see what will happen to the first students of online courses. :)
