Good. Since you’re on **Windows**, the first thing a DevOps engineer must do is **create a Linux environment**. Almost **every production server runs Linux**, so DevOps work is done there — not in native Windows.

We will set up your machine exactly like a real DevOps workstation.

---

# Step 1 — Install WSL2 (Linux inside Windows)

WSL = **Windows Subsystem for Linux**.  
It allows you to run **Ubuntu Linux directly inside Windows**.

Open **PowerShell as Administrator** and run:

```bash id="u7e7os"
wsl --install
```

This command will:

1. Enable WSL
2. Install Ubuntu
3. Set WSL2 as default
4. Download Linux kernel

After installation **restart your PC**.

---

# Step 2 — Launch Ubuntu

After reboot:

Open **Ubuntu** from the start menu.

The first time it runs it will ask you to create:

``` id="msqa6l"
username
password
```

Example:

``` id="v0c5sp"
username: logboi
password: ********
```

You now officially have a **Linux machine running inside Windows**.

---

# Step 3 — Update the Linux System

Run this:

```bash id="qg212b"
sudo apt update && sudo apt upgrade -y
```

Explanation:

| Command | Meaning |
|---|---|
| sudo | run as administrator |
| apt update | update package list |
| apt upgrade | upgrade installed packages |

---

# Step 4 — Install Essential DevOps Tools

Install basic tools:

```bash id="vwxtrv"
sudo apt install -y curl wget git unzip build-essential
```

Check installation:

```bash id="qhkmjs"
git --version
curl --version
```

---

# Step 5 — Install Node (Important for Your Projects)

Since you build apps (NextJS, etc), install Node.

```bash id="kjhu3j"
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt install -y nodejs
```

Check:

```bash id="v7pmgn"
node -v
npm -v
```

---

# Step 6 — Install Docker (DevOps Core Tool)

Docker is **non-negotiable** in DevOps.

Install it:

```bash id="ort6yy"
sudo apt install docker.io -y
```

Enable docker:

```bash id="jxlard"
sudo systemctl enable docker
```

Start docker:

```bash id="10bqiq"
sudo systemctl start docker
```

Check:

```bash id="lrsu1u"
docker --version
```

Test docker:

```bash id="ynchhx"
docker run hello-world
```

You should see:

``` id="qf3b80"
Hello from Docker!
```

---

# Step 7 — Fix Docker Permission (Important)

Without this, you must type `sudo` every time.

Run:

```bash id="mzxfj9"
sudo usermod -aG docker $USER
```

Then restart WSL:

```bash id="sv14tt"
exit
```

Reopen Ubuntu.

Test:

```bash id="b116l0"
docker run hello-world
```

---

# Your DevOps Environment is Now Ready

You now have:

``` id="ak1ul0"
Windows
   ↓
WSL2
   ↓
Ubuntu Linux
   ↓
Docker
   ↓
Git
   ↓
Node
```

This is the **standard DevOps development stack**.

---

# Your First DevOps Exercise

Inside Ubuntu run these commands:

```bash id="vgbr8q"
mkdir devops-lab
cd devops-lab
touch test.txt
echo "DevOps journey begins" > test.txt
cat test.txt
```

If everything works you should see:

``` id="mgjgn6"
DevOps journey begins
```

---

# Next Lesson (Real DevOps Work)

In the next step I will teach you something **very powerful**.

You will learn:

### SSH + Remote Servers

We will:

``` id="jwtt05"
Create a cloud server
SSH into it
Deploy an application
Expose it to the internet
Add SSL
```

You will literally deploy your **first production server like a real DevOps engineer**.

---

Before we continue tell me:

1️⃣ Did **WSL install successfully?**  
2️⃣ Did **docker run hello-world work?**

After that we move to the **first real DevOps deployment**.
