Registration is open for intensive on Kubernetes on February 1-3 in St. Petersburg

Registration is open for Slurm-3 .

This is a three-day Kubernetes intensive for those who do not know anything about the technology or began to master it. Chip intensive in practice. Each participant will create a cluster in the Selectel cloud, configure it and deploy the application in it.

Slurm 3 will be held in St. Petersburg on February 1–3, 2019.

Why do I need Slurm if there are manuals? It saves several months, which you would otherwise spend on reading and independent experiments.

Brief background.

The first Slurm took place in August 2018. It was an experiment that was successful, despite a lot of mistakes and problems. Report .

In mid-October, Pavel Selivanov, the main speaker of Slurm, held a webinar on "Do you need Kubernetes?" Under the link - decoding of the main thoughts.

The second Slurm was held in October. We took into account organizational failures. Speakers went to the courses on oratory and teaching. An online version and a support team appeared that helped participants find bugs. As a result, I wrote a post: "Dear courses: is it worth it?"

We will try to do the third Slurm better than the second.

Places only 100, 50 - live participation, 50 - online.
