Docker Deployment Guide

Overview

This guide covers Docker deployment for all OASIS ecosystem components:

  • OASIS API Web API (.NET 8)

  • STAR API Web API (.NET 9)

  • OASIS OPORTAL (.NET 8 + React)

  • STAR WEB UI (.NET 8 + React)

  • OASIS WEB UI (React + Nginx)

Prerequisites

  • Docker Desktop installed

  • Docker Compose installed

  • Git repository cloned

🚀 Quick Start

1. Build All Images

# Build all services
docker-compose build

# Or build specific service
docker-compose build oasis-api
docker-compose build star-api
docker-compose build oasis-oportal
docker-compose build star-web-ui

2. Run All Services

# Start all services
docker-compose up -d

# View logs
docker-compose logs -f

# Stop all services
docker-compose down

3. Access Services

  • OASIS API: http://localhost:5000

  • STAR API: http://localhost:5001

  • OASIS OPORTAL: http://localhost:5002

  • STAR WEB UI: http://localhost:5003

  • OASIS WEB UI: http://localhost:3000

📋 Individual Service Deployment

OASIS API Web API (.NET 8)

# Build image
docker build -f ONODE/NextGenSoftware.OASIS.API.ONODE.WebAPI/Dockerfile -t oasis-api .

# Run container
docker run -p 5000:8080 -e ASPNETCORE_ENVIRONMENT=Production oasis-api

# Health check
curl http://localhost:5000/api/health

STAR API Web API (.NET 9)

# Build image
docker build -f "STAR ODK/NextGenSoftware.OASIS.STAR.WebAPI/Dockerfile" -t star-api .

# Run container
docker run -p 5001:8080 -e ASPNETCORE_ENVIRONMENT=Production star-api

# Health check
curl http://localhost:5001/api/health

OASIS OPORTAL (.NET 8 + React)

# Build image
docker build -f ONODE/NextGenSoftware.OASIS.API.ONODE.OPORTAL/Dockerfile -t oasis-oportal .

# Run container
docker run -p 5002:8080 -e ASPNETCORE_ENVIRONMENT=Production oasis-oportal

STAR WEB UI (.NET 8 + React)

# Build image
docker build -f "STAR ODK/NextGenSoftware.OASIS.STAR.WebUI/Dockerfile" -t star-web-ui .

# Run container
docker run -p 5003:8080 -e ASPNETCORE_ENVIRONMENT=Production star-web-ui

# Health check
curl http://localhost:5003/

OASIS WEB UI (React + Nginx)

# Build image
docker build -f oasisweb4.com/Dockerfile -t oasis-web-ui .

# Run container
docker run -p 3000:80 oasis-web-ui

# Health check
curl http://localhost:3000/health

🔧 Configuration

Environment Variables

Create a .env file in the root directory:

# Database
POSTGRES_DB=oasis
POSTGRES_USER=oasis
POSTGRES_PASSWORD=oasis123

# API URLs
OASIS_API_URL=http://oasis-api:8080
STAR_API_URL=http://star-api:8080

# Environment
ASPNETCORE_ENVIRONMENT=Production

Custom Ports

Modify docker-compose.yml to change ports:

services:
  oasis-api:
    ports:
      - "8080:8080"  # Change first number for host port

🏗️ Production Deployment

1. Docker Swarm

# Initialize swarm
docker swarm init

# Deploy stack
docker stack deploy -c docker-compose.yml oasis-stack

# Scale services
docker service scale oasis-stack_oasis-api=3

2. Kubernetes

# Convert compose to k8s manifests
kompose convert

# Apply to cluster
kubectl apply -f .

3. Cloud Platforms

Railway

  • Push to GitHub

  • Connect repository to Railway

  • Railway auto-detects Dockerfiles

AWS ECS

  • Build and push to ECR

  • Create ECS task definitions

  • Deploy using ECS service

Azure Container Instances

  • Build and push to ACR

  • Deploy using Azure CLI

📊 Monitoring & Health Checks

Health Check Endpoints

  • OASIS API: /api/health

  • STAR API: /api/health

  • OPORTAL: /

  • STAR WEB UI: /

  • OASIS WEB UI: /health

Logs

# View all logs
docker-compose logs

# View specific service logs
docker-compose logs oasis-api

# Follow logs in real-time
docker-compose logs -f star-api

Resource Monitoring

# Container stats
docker stats

# Service status
docker-compose ps

🔒 Security Best Practices

1. Use Multi-stage Builds

All Dockerfiles use multi-stage builds to minimize image size.

2. Non-root User

# Add to Dockerfile
RUN adduser -D -s /bin/sh appuser
USER appuser

3. Security Scanning

# Scan images for vulnerabilities
docker scan oasis-api
docker scan star-api

4. Secrets Management

# Use Docker secrets
echo "mysecret" | docker secret create db_password -

🚨 Troubleshooting

Common Issues

Build Failures

# Clean build
docker-compose build --no-cache

# Check build logs
docker-compose build oasis-api

Port Conflicts

# Check port usage
netstat -tulpn | grep :5000

# Change ports in docker-compose.yml

Memory Issues

# Increase Docker memory limit
# Docker Desktop → Settings → Resources → Memory

Database Connection

# Check database logs
docker-compose logs postgres

# Connect to database
docker-compose exec postgres psql -U oasis -d oasis

Debug Commands

# Enter container
docker-compose exec oasis-api sh

# Check container processes
docker-compose exec oasis-api ps aux

# Check network connectivity
docker-compose exec oasis-api ping star-api

📈 Performance Optimization

1. Image Optimization

  • Use Alpine Linux base images

  • Multi-stage builds

  • Remove unnecessary packages

2. Caching

  • Layer caching for faster builds

  • Use .dockerignore files

  • Order Dockerfile commands by frequency of change

3. Resource Limits

services:
  oasis-api:
    deploy:
      resources:
        limits:
          memory: 512M
          cpus: '0.5'

🔄 CI/CD Integration

GitHub Actions

name: Build and Push Docker Images
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Build and push
        run: |
          docker-compose build
          docker-compose push

GitLab CI

build:
  stage: build
  script:
    - docker-compose build
    - docker-compose push
