Yea but that doesn't sound shiny on your resume.

I never did choose any single thing in my job, just because of how it could look in my resume.

After +20 years of Linux sysadmin/devops, and because a spinal disc herniation last year, now I'm looking for a job.

99% of job offers, will ask for EKS/Kubernetes now.

It's like the VMware of the years 200[1-9], or like the "Cloud" of the years 201[1-9].

I've always specialized in physical datacenters and servers, being it on-premises, colocation, embedded, etc... so I'm out of the market now, at least in Spain (which always goes like 8 years behind the market).

You can try to avoid it, and it's nice when you save thousands of operational/performance/security/etc issues and dollars to your company across the years, and you look like a guru that goes ahead of industry issue to your boss eyes, but, it will make finding a job... 99% harder.

It doesn't matter if you demonstrate the highest level on Linux, scripting, ansible, networking, security, hardware, performance tuning, high availability, all kind of balancers, switching, routing, firewalls, encryption, backups, monitoring, log management, compliance, architecture, isolation, budget management, team management, provider/customer management, debugging, automation, programming full stack, and a long etc. If you say "I never worked with Kubernetes, but I learn fast", with your best sincerity at the interview, then you're automatically out of the process. No matter if you're talking with human resources, a helper of the CTO, or the CTO. You're out.

Depends on what kind of company you want to join. Some value simplicity and efficiency more.
