Here’s the part they don’t put in the DevOps job description:

You inherit the problems nobody else wants.

Your job isn’t just pipelines, clusters, or infra as code.

Your job is fixing everything that touches production.

- Flaky CI pipelines.
- Untuned autoscaling.
- Leaking secrets in logs.
- Stale container images.
- DNS records gone wild.
- Incidents with no runbooks.
- And more.

If developers ship it, users run on it, or customers rely on it.

It’s your problem. 

Learn Linux, networking, security, debugging more than DevOps tools.

And you’re already 90% ahead of others.

I said 1000 times 'Learn Linux Before DevOps'. 

Many DevOps engineers struggle to talk with Linux while troubleshooting. 

Things like basic commands, file paths, environment variables, services that won’t start, or stuck processes.

So, I created this to help you.

Start here and build from this foundation.

Kubernetes is powerful, but it punishes weak foundations.

Though we can't eliminate the chaos completely.

If you want fewer alarms and less coffee:
• Learn how your cluster picks nodes
• Learn CPU and memory requests and limits
• Learn how observability reduces invisible failures
• Learn why your CNI controls half your workload stability
• Learn the difference between scaling apps and scaling infra

At least you sleep better.

Hiring in DevOps is broken.

The job market rewards the wrong signals.

Job postings scream for certifications.
Recruiters filter resumes on keywords.

So what do we get?
More and more tutorial watchers and paper certified engineers.

But here’s the reality:
- Certifications can open a door, but they don’t build systems.
- Watching tutorials doesn’t prepare you for production fires at 2 am.

Build projects from AWS or any white papers.
Architect systems, even if small, and iterate on them.

Think about it.

2023: No salary increase
2024: No salary increase
2025: No salary increase

Employee: please accept my resignation

CEO: You have done amazing in the company. Why are you resigning? 

Employee: I have found a company with a 90% base salary increase and guaranteed salary promotions as long as I meet my performance goals. 

36 hours later….

CEO: We will match you! Please stay, we value your hard work! 

Employee: Unfortunately Monday is my last day.

Salary revisions still run on 90s thinking,
while companies talks about AI, disruption, and evolution.

Do the obvious thing.
Build skills. Go where they pay for them.

Most Kubernetes errors aren’t Kubernetes errors. They’re Linux. 

Almost every pod, every container, every node… runs on Linux.

Troubleshooting a pod stuck in CrashLoopBackOff?
You’ll end up checking Linux logs.

Struggling with persistent volumes? 
You’re debugging Linux file systems.

Networking in Kubernetes? 
It’s still Linux networking namespaces and iptables.

Kubernetes is powerful, but it doesn’t replace the basics.
It builds on them.

Master Linux first. 
Kubernetes will make a lot more sense after that.

DevOps new hires' life explained.

Even experts need guidance in understanding your system’s setup and history.

Without clear knowledge of the current design, key links, and hidden issues, expecting full productivity in weeks is unrealistic.

System knowledge isn’t the same as technical skills.

I've faced this challenge many times before.

Focusing on the basics helped me early on.

To pick up:
- API flows
- Network boundaries
- Integration endpoints

and more to watch out for...

Stop expecting your new DevOps hires to 'figure it out.'

Anurag P.

Kubernetes itself still confuses half the world.
Leaders are pushing AI Agents on Kubernetes. Seriously?

When you:
- Do not understand JVM memory inside containers
- Do not know how to craft a lean and secure image
- Do not tune CPU and heap for real world workloads

How can DevOps run complex projects in production without even mastering the basics?

Many leaderships only got ambitions but not the hands on opportunities for their teams to learn.

Luckily Bellsoft Community created a hands on workshop.

The workshop is delivering:
End to end workflow from build to prod ready deployment.

When hiring, remember that not all DevOps Engineers are the same. 

Some are strong in CI/CD. 
Some are skilled in scripting. 
Some are specialists in security. 
Some are great with containers. 
Some are proficient in IaC tools. 
Some are experts in Kubernetes. 
Some are pros at cost optimization. 
Some are specialized in networking. 
Some are focused on cloud platforms. 
Some are excellent at disaster recovery. 
Some are passionate about observability. 
Some are great with hybrid environments. 
Some are experienced in performance optimization. 

Most can handle some of these or a mix of them. 

But no DevOps Engineer should be expected to master or handle all of them.

Be clear about what you need and hire a DevOps Engineer who fits those specific needs - not EVERY SINGLE THING.

All the money in the world doesn't matter if you don't have your health.

- Prioritize self-care
- Eat whole foods
- Drink water
- Exercise

Add:

- Workplaces that respect boundaries
- Build skills that stay relevant
- Invest in long term energy
- Take breaks seriously

Years from now, Kubernetes upgrades and zero downtime deployments will matter less than health, skills and workplaces that let you grow.

Many think DevOps = tools + pipelines.
Hook up Jenkins, Terraform, Kubernetes… done, right?
That’s the easy part.

The hard part?
- Outages at 2 AM
- Escalations nobody wants
- Cloud costs burning money
- Scaling that never behaves
- Downtime you can’t predict

The number of candidates and decision makers missing this is mind boggling.

If you want to grow in DevOps:
Focus less on tools, more on running resilient systems under chaos.

Confused between Dockerfile and Docker Compose? 

This is for you.

Although they are complementary, they serve different purposes in your containerized environment.

𝗗𝗼𝗰𝗸𝗲𝗿𝗳𝗶𝗹𝗲: Used to create and build Docker images.

𝗗𝗼𝗰𝗸𝗲𝗿 𝗖𝗼𝗺𝗽𝗼𝘀𝗲: Used to run Docker containers as part of a multi-container setup or with specific runtime configurations.

Note: From version 1.28.6, Docker Compose defaults to compose.yaml or compose.yml, with backward compatibility for docker-compose.yaml/yml. If both exist, compose.yaml is preferred.

Here, I've created a simple illustration to help you better understand.

How can Kubernetes Engineers get proper sleep?

Many leaderships want 99.99 uptime but do not give teams the space, tools, or staffing to actually breathe.

When you:
- Do not understand JVM memory inside containers
- Do not know how to craft a lean and secure image
- Do not tune CPU and heap for real world workloads

How can teams even run small Java applications without these?

Luckily PerfectScale created a practical workshop for this.

The workshop is delivering:
- How to build the perfect Java image for Kubernetes
- Choosing the right JDK, distroless and base image
- Setting proper JVM memory limits for containers
- Understanding heap, GC and startup behavior in K8s
- Image size, performance and security optimizations
- End to end workflow from build to prod ready deployment

A gentle reminder for DevOps engineers
(you will thank me later):

✓ Learn Linux before Kubernetes.

✓ Learn Networking before VPCs.

✓ Learn Containers before EKS or AKS.

✓ Learn IAM before multi account setups.

✓ Learn EC2 basics before Autoscaling Groups.

✓ Learn DNS before Ingress controllers.

✓ Learn Load Balancing before Service Mesh.

✓ Learn CI basics before full CD pipelines.

✓ Learn Stateful apps before StatefulSets.

✓ Learn Resource Requests before Karpenter.

✓ Learn Pod lifecycle before Operators.

The bottom line:

→ Learn the basics before anything else.
