In this article, we'll walk through the complete process of working with nexus in a server environment. Understanding artifacts is essential for maintaining a reliable and performant infrastructure.
Prerequisites
- Root or sudo access to the server
- Basic familiarity with the Linux command line
- A Git repository for your project
- A VPS running Ubuntu 22.04 or later (2GB+ RAM recommended)
Pipeline Configuration
Regular maintenance is essential for keeping your nexus installation running smoothly. Schedule periodic reviews of log files, disk usage, and security updates to prevent issues before they occur.
# .github/workflows/deploy.yml
name: Deploy to Production
on:
push:
branches: [main]
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Build
run: |
docker build -t myapp:latest .
- name: Deploy
run: |
ssh deploy@server 'cd /opt/myapp && docker compose pull && docker compose up -d'
Each line in the configuration serves a specific purpose. The comments explain the reasoning behind each setting, making it easier to customize for your specific use case.
Build and Test Setup
Security should be a primary consideration when configuring nexus. Always use strong passwords, keep software updated, and restrict network access to only the necessary ports and IP addresses.
# Set up deployment pipeline
mkdir -p /opt/myapp
cd /opt/myapp
# Create deployment script
cat << 'EOF' > deploy.sh
#!/bin/bash
set -euo pipefail
echo "Deploying version: $1"
docker pull myapp:$1
docker compose down
DOCKER_TAG=$1 docker compose up -d
echo "Deployment complete"
EOF
chmod +x deploy.sh
These commands should be run as root or with sudo privileges. If you're using a non-root user, prefix each command with sudo.
Advanced Settings
The default configuration works well for development environments, but production servers require additional tuning. Pay particular attention to connection limits, timeout values, and logging settings.
Wrapping Up
Following this guide, your nexus setup should be production-ready. Keep an eye on resource usage as your traffic grows and don't forget to test your backup and recovery procedures periodically.
