You don’t need to have it all figured out before you start.

Every DevOps expert was once a beginner trying to understand Linux commands, cloud tools, and deployment pipelines. The difference? They started anyway.

Start small. Stay consistent. Build skills that open doors.

Day 6/14 — Why Containers Changed CI/CD Forever 🐳

Before containers, CI/CD was painful.

Deployments depended on:

• Server configuration
• Installed dependencies
• OS differences
• “It works on my machine”

Everything was fragile.

Then containers changed everything 👇

Enter:

Docker

Instead of deploying code…

You deploy an **environment + code together**.

Same app.
Same dependencies.
Same behavior.

Anywhere.

Here’s the shift:

Old way:

Code → Server → Hope it works

Modern way:

Code → Container → Run anywhere

That one change fixed a huge problem:

❌ Environment inconsistencies
❌ Dependency conflicts
❌ Manual server setup

Now combine this with CI/CD:

Git push → CI runs → Build container → Push image → Deploy

You’re no longer deploying code.

You’re deploying **immutable artifacts**.

Why this is powerful:

Containers are:

• Portable → Run anywhere
• Consistent → Same in dev & prod
• Versioned → Easy rollback
• Isolated → No dependency conflicts

This is why modern pipelines depend on them.

And when you scale this…

You need orchestration tools like:

• Kubernetes

To manage:

• Multiple containers
• Scaling
• Self-healing
• Rolling deployments

Here’s the truth:

If your CI/CD pipeline doesn’t produce a container image…

You’re missing out on one of the biggest advantages in modern DevOps.

Simple mental model:

CI = Build & test
Container = Package
CD = Deploy

Tomorrow (Day 7):

I’ll break down **how container registries work and why they matter**.

If I were to learn DevOps from scratch with zero experience, here’s exactly how I’ll do it

I wrote this guide to help beginners understand:
• what DevOps actually is
• what to learn first
• how to start building real skills
If you're curious about DevOps but don’t know where to begin, this is for you.

@devops_sre18 Truth. But let’s be fair — Terraform can get painful at extreme scale without good state management, locking, and workspaces. The tool doesn’t break, but the ergonomics force better habits

[Ifeoluwa Adaralegbe @devopsguy001]

@twtayaan You start feeling like a star 😅

Day 5/14 — Let’s Build a Real CI Pipeline ⚙️

Enough theory.

Today we’ll build a **simple CI pipeline** that:

• Runs tests on every push
• Builds a Docker image
• Pushes it to a container registry

All automatically.

Let’s walk through it 👇

First, the CI tool.

For this example we’ll use:

GitHub Actions

Why?

• Built into GitHub
• Simple YAML configuration
• Perfect for most projects

All pipelines live inside:

`.github/workflows/`

Now create a workflow file:

`ci.yml`

Example pipeline:

```yaml
name: CI Pipeline

on:
push:
branches: [ main ]

jobs:
build:
runs-on: ubuntu-latest

steps:
- name: Checkout code
uses: actions/checkout@v4

- name: Set up Docker
uses: docker/setup-buildx-action@v3

- name: Run tests
run: npm test

- name: Build Docker image
run: docker build -t myapp:${{ github.sha }} .
```

Every push to `main` now triggers this pipeline.

What happens when you push code?

1️⃣ Git push
2️⃣ Pipeline starts automatically
3️⃣ Code is checked out
4️⃣ Tests run
5️⃣ Docker image builds

If anything fails, the pipeline stops.

That’s CI doing its job.

Now let’s talk artifacts.

Instead of rebuilding code later, we store the output.

In container-based systems this is usually a:

Docker image.

That image becomes the **exact version deployed later**.

Immutable builds = reliable deployments.

Why this matters:

Without CI:

• Bugs reach production
• Developers break each other’s code
• Debugging becomes chaos

With CI:

Every change is tested automatically.

Your CI pipeline should be:

✔ Fast
✔ Reliable
✔ Automated
✔ Easy to understand

Complex pipelines become technical debt.

Keep them simple.

Tomorrow (Day 6):

Why containers completely changed CI/CD pipelines

@devops_sre18 True 😂

[Ifeoluwa Adaralegbe @devopsguy001]

@asynctrix Spot on! Prioritize Karpenter + IRSA + AWS LB Controller. Add GitOps (ArgoCD) and EKS add-ons for production readiness.

[Ifeoluwa Adaralegbe @devopsguy001]

@devops_nk If the workflow exists only in the feature branch and not in the base branch, GitHub may not run it depending on the event configuration. Often the workflow must exist in the default branch.

[Ifeoluwa Adaralegbe @devopsguy001]

@twtayaan Fully agree on cross-region replication. For recovery try pulling a previous version from the backend, then terraform refresh or selective imports if needed

[Ifeoluwa Adaralegbe @devopsguy001]

@lloydtheophilus True!

The FinOps point hits hardest, zombie volumes and egress leaks are silently bleeding budgets way more than most admit.

[Ifeoluwa Adaralegbe @devopsguy001]

@devops_nk True!
Companies hire SRE mindset now, problem-solvers who own the fire, not just the tools.
Break your own clusters, monitor the mess, fix it fast—that’s the 2026 edge.
