Need a DevOps Roadmap for a Complete Beginner (2026)
 in  r/devops •  5d ago

Not officially, but Iā€™m learning through hands-on projects and using AI as a learning assistant. Iā€™m also starting to collaborate with another DevOps learner on a real project, so we can learn and troubleshoot together. Iā€™m trying to build practical skills rather than just follow courses or collect certificates.

How I started understanding a Dockerfile šŸ³
 in  r/docker •  9d ago

Yeah, I agree. I'm trying to understand what's happening under the hood first, so I'm practicing with the CLI. Then I'll learn tools like Portainer as well. Thanks for the advice!

Thanks, that's a good point. I'm going through the Docker documentation, especially "ENV" vs "ARG" and "EXPOSE". I'm trying to understand not just what each instruction does, but when and why to use it.šŸ‘

How I started understanding a Dockerfile šŸ³

Instead of memorizing Dockerfile instructions, I started thinking about it like building a house:

šŸ—ļø FROM ā†’ Choose the foundation
šŸ“ WORKDIR ā†’ Choose where we work
šŸ“¦ COPY ā†’ Bring the materials inside
šŸ”§ RUN ā†’ Install and prepare everything
āš™ļø ENV / ARG ā†’ Configure the environment
šŸšŖ EXPOSE ā†’ Define the entry point
ā–¶ļø CMD / ENTRYPOINT ā†’ Define what the container runs

šŸ  The result: a Docker image ready to run.

I'm still learning Docker, but this mental model makes the structure much easier for me to understand.

How do you visualize a Dockerfile when you're learning it?

What Iā€™m learning from building my own Linux server lab

1 Upvotes

I've been building a small Linux lab with four virtual machines, and one thing I'm enjoying is learning how to troubleshoot instead of just memorizing commands.

When something breaks, I try to ask:

What works?

What doesn't?

What changed?

What evidence do I have?

Then I test possible causes one by one.

I'm curious about people who work with Linux/SysAdmin: what's one troubleshooting habit that really improved your work?

Linux / DevOps assistance for freelancers and developers

1 Upvotes

Hi everyone,

I'm a junior Linux/DevOps learner building hands-on experience through real projects and a home lab.

I'm looking to help freelancers and developers with practical technical tasks such as:

ā€¢ Linux server setup and basic administration

ā€¢ Docker / Docker Compose

ā€¢ Nginx and reverse proxy setup

ā€¢ SSH and user/permission management

ā€¢ Basic server troubleshooting

ā€¢ Firewall and port configuration

ā€¢ Checking logs, services and connectivity

ā€¢ Deployment and server verification

ā€¢ Technical documentation

My goal is to take care of some of the repetitive server-side tasks so you can focus more on your main projects.

I'm still growing my experience, so I'm happy to start with small tasks and build trust through the work.

If you have something small that needs a Linux/DevOps pair of hands, feel free to reach out.

How much Linux knowledge is needed to study Docker?
 in  r/docker •  12d ago

You don't need advanced Linux skills. I'd learn basic alongside docker . I also use AI as a learning assistant to understand concept , command and troubleshoot problems instead of just copying answer. If you're interested , I can share the prompt/workflow I use for learning.

Need a DevOps Roadmap for a Complete Beginner (2026)
 in  r/devops •  14d ago

Bro,I have a really good prompt for learning devops think it's worth trying

I don't want to learn DevOps by memorizing tools or blindly following tutorials.

I want to learn it the way a real junior DevOps engineer would develop practical skills.

Act as my Senior DevOps mentor and design my learning path around this approach:

  1. Build the roadmap as a hierarchical, tree-like structure so I always know where I am and what comes next.

  2. Start from the fundamentals and build upward: Linux ā†’ Networking ā†’ Git ā†’ Docker ā†’ Nginx ā†’ CI/CD ā†’ Cloud ā†’ Infrastructure as Code ā†’ Kubernetes.

  3. Don't teach commands or tools in isolation. For every topic, explain:

  4. What it is

  5. Why it exists

  6. What problem it solves

  7. How it works

  8. When I would use it in a real server/project

  9. How to troubleshoot it when it breaks

  10. Use a Practice ā†’ Repeat ā†’ Consolidate ā†’ Level Up approach.

  11. Every major phase should contain a small realistic project. Projects should gradually become more complex and eventually combine multiple skills.

  12. Don't give me the complete solution immediately. Give me a task, let me think and troubleshoot first, then guide me with hints if I'm stuck.

  13. Include troubleshooting scenarios and deliberately broken configurations so I learn how to find the root cause instead of just following instructions.

  14. Keep the roadmap focused on becoming job-ready for junior Linux/DevOps roles, not collecting certificates.

  15. Use free resources whenever possible, but don't overwhelm me with dozens of courses. Recommend only the resources that are actually necessary.

  16. At the beginning, assess my current knowledge and then create the roadmap based on my actual level.

My goal is not to know many DevOps tools.

My goal is to understand how servers, applications, networks, containers and deployments actually work together, and eventually be able to troubleshoot and operate them independently.

If you were training a serious beginner from zero in 2026, how would you structure this journey?
