Installation & Setup

Below is a step‑by‑step guide that walks you through preparing the system, installing Docker, and deploying a sample container stack. All Docker commands use the placeholder variables $CONTAINER_ID, $CONTAINER_NAMES, $CONTAINER_STATUS, $CONTAINER_IMAGE, $CONTAINER_PORTS, $CONTAINER_COMMAND, and $CONTAINER_CREATED to stay compatible with Jekyll’s Liquid templating.

1. Install Docker Engine

# Update package index
sudo apt-get update -y

# Install prerequisite packages
sudo apt-get install -y ca-certificates curl gnupg lsb-release

# Add Docker’s official GPG key
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg# Set up the stable repository
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] \
  https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# Refresh the apt cache
sudo apt-get update -y

# Install Docker Engine
sudo apt-get install -y docker-ce docker-ce-cli containerd.io

# Verify installation
docker version

2. Add Your User to the Docker Group

sudo usermod -aG docker $USER
newgrp docker

3. Deploy a Sample Service Using Docker Compose

Create a docker-compose.yml file with the following content:

version: "3.9"
services:
  monitoring:
    image: prom/prometheus:latest
    container_name: $CONTAINER_NAMES
    restart: unless-stopped
    ports:
      - "9090:9090"
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
    environment:
      - LOG_LEVEL=info
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9090/-/healthy"]
      interval: 30s      timeout: 10s
      retries: 3
      start_period: 40s
      end_check: false```

**Explanation of Key Sections**

* `container_name` – Allows you to reference the container via `$CONTAINER_NAMES` in scripts.  
* `ports` – Maps the internal Prometheus port to the host’s 9090, accessible via `$CONTAINER_PORTS`.  
* `healthcheck` – Uses a simple curl command to verify service health; the output can be inspected with `$CONTAINER_STATUS`.  

### 4. Bring Up the Stack

```bash
docker compose up -d
# Verify that containers are running
docker ps
# Check the status of the newly created container
docker inspect $CONTAINER_ID --format='{{.State.Status}}'

5. Verify Persistent Storage

```bash# List volumes to confirm persistence docker volume ls

Inspect the volume details

docker volume inspect $CONTAINER_ID

### 6. Configure Automatic Start on Boot

```bash# Enable Docker to start at boot
sudo systemctl enable docker

# Verify the service statussystemctl status docker

7. Secure Docker Daemon

# Create a configuration file for Docker daemon
cat <<EOF | sudo tee /etc/docker/daemon.json
{
  "exec-opts":
