Slurm is growing.
In St. Petersburg on there were 70 people in the hall. Moscow parachuted 104 people into the conference hall of the Sevastopol Hotel. Another record that modestly tells us that we are going in the right direction. They settled down and were not cramped and not offended.
Before the start of Slurm, the lecturer asked to turn off the sound of mobile phones.
He also asked me to open the cans of Cola in advance so that the hissing would not interrupt the lecturer’s voice. Everyone reacted quickly, clearly and obediently. The speaker clearly did not expect such an effect. A volley of hundreds of CocaCola cans was heard - almost a cannon volley from the side of the pirate-administrator's ship. Fireworks marking the beginning.
Three speakers gathered to dissect K8S - two experienced and one beginner.
Pavel Selivanov probably doesn’t even need to be introduced. But still... He is an administrator with 10 years of experience and a Certified Kubernetes Administrator. He tormented Kubernetes during five individual projects. And at twenty I took part. At the sight of him, Kubernetes runs away screaming - because he understands that Pavel will do something new with him, which Salvador Dali will envy. Pavel Selivanov has already told how - no humanism.
Sergey Bondarev is also known to Slurm participants. Administrator with 20 years of experience, Certified Kubernetes Administrator. All of Southbridge's cube projects, including its own infrastructure, bear his fingerprints, like Russian radio operator Kat's suitcase. I once accomplished a Herculean feat - in one company, in 5 days of work, I raised private Kubernetes and trained IT support employees. Sergey forgot more about setting up software and hardware than other system administrators learn in their entire lives.
And the new, very motivated, experienced and lively Marcel Ibraev. Administrator with 6 years of experience, Certified Kubernetes Administrator. For an international company, I developed infrastructure from scratch - the company cried and tried to escape, but it had no chance. Marcel deployed it and set up a full-fledged infrastructure according to pre-agreed plans and client wishes, and conducted staff training. They still shout "K8S" at night.
On the first day, the participants received, like Pinocchio, the alphabet in order to remember all the “az”, “buki”, “vedi”, “verb”, so that occasional gaps in knowledge would not interfere with further learning.
While everyone was remembering, the experienced and cunning participants wasted no time and broke the Pentagon.
No less experienced colleagues, having taped up the eyes of their video cameras, under the guise of studying K8S, broke the US election system, the traffic light system and the Salisbury spiers and pestered the First Lady of the United States through personal government communications.
The introduction to k8s technology smoothly turned into a conversation about Pod, ReplicaSet, Deployment, Service, Ingress, PV, PVC, ConfigMap, Secret. And then they sealed it with practice.
Sergei Bondarev watches relaxedly as Pavel Selivanov takes the rap for two on stage.
We had just had a short coffee break when topics started flying from Marcel Ibraev about the design of the cluster, the main components, fault tolerance, and the k8s network.
And after a hearty lunch at the Crimea restaurant, which we occupied with a horde of 100+ people, the speakers took up Kubespray, tuning and setting up a Kubernetes cluster, along with practice, of course.
One participant liked the presenter’s microphone so much that he simply took it away during the agitation.
Technical support did not leave the participants for a minute. She gave advice in Kubernetes on when to buy Bitcoin, whether it’s worth investing in Pavel Durov’s Gram, who is cooler, Spartak or CSKA, and what question to answer 42.
We have long ago formed a concept for Slurm - from simple steps to complex ones. The intensive course is structured in such a way that the difficulty increases every day, so that the brain gradually increases its speed and the transmission does not fall off. So on the second day everything will be even bigger, even more interesting, even more useful.
PS And just a little bit of Slurm:
