Got it, let's fix your Sybase issue in the docker-compose setup. Since you don't want to build a custom image, we'll use a pre-built, community-validated Sybase ASE image and integrate it seamlessly with your existing DB2 and SQL Server services.

Full Docker Compose Example (Including Sybase) #

Here's a complete docker-compose.yml that includes all three databases, with Sybase configured correctly (keep your working DB2/SQL Server config intact, just add the Sybase block):

version: '3.8'

services:
  # Your existing DB2 service (retain your working configuration here)
  db2:
    image: ibmcom/db2:11.5.8.0
    environment:
      - DB2INST1_PASSWORD=your_db2_secure_pass
      - DBNAME=sample_db
    ports:
      - "50000:50000"
    volumes:
      - db2-data:/database
    restart: unless-stopped

  # Your existing SQL Server service (retain your working configuration here)
  sqlserver:
    image: mcr.microsoft.com/mssql/server:2022-latest
    environment:
      - ACCEPT_EULA=Y
      - SA_PASSWORD=your_sqlserver_secure_pass
    ports:
      - "1433:1433"
    volumes:
      - sqlserver-data:/var/opt/mssql
    restart: unless-stopped

  # Sybase ASE Service (new, production-ready configuration)
  sybase:
    # Use a trusted community-maintained image (alternatives noted below)
    image: jbarlow-mcafee/sybase-ase:16.0
    environment:
      # Mandatory vars for Sybase initialization
      - SA_PASSWORD=SybasePass_123!  # Must meet complexity: 8+ chars, mix of cases, numbers/symbols
      - SYBASE_DB=your_sybase_target_db  # Initial database to create on startup
      - SYBASE_USER=your_sybase_non_sa_user  # Optional: Create a restricted user
      - SYBASE_PASSWORD=UserPass_456!  # Password for the non-sa user
    ports:
      - "5000:5000"  # Sybase ASE default port
    volumes:
      # Persist Sybase data across container restarts
      - sybase-data:/opt/sybase/data
      # Optional: Mount SQL scripts to run on first boot (create tables, users, etc.)
      # - ./sybase-init-scripts:/opt/sybase/init
    restart: unless-stopped
    # Health check to avoid connection errors during startup (Sybase is slow to initialize)
    healthcheck:
      test: ["CMD", "isql", "-Usa", "-P${SA_PASSWORD}", "-Slocalhost:5000", "-Q", "select 1"]
      interval: 30s
      timeout: 10s
      retries: 10
      start_period: 120s  # Sybase takes ~2 minutes to fully start and accept connections

volumes:
  db2-data:
  sqlserver-data:
  sybase-data:

Key Sybase Configuration Notes #

Let’s break down the critical bits to avoid common pitfalls:

• Image Selection: The jbarlow-mcafee/sybase-ase:16.0 is a reliable community option. If you need an official SAP image, use sap/sybase-ase:16.0 but note you’ll need to log into SAP’s container registry first with docker login registry.sap.io.
• Password Rules: Sybase enforces strict password complexity by default. Skip this, and you’ll get startup errors immediately.
• Health Check: Sybase takes way longer to spin up than SQL Server/DB2. The start_period and retry count ensure we don’t mark the service as healthy before it’s ready to accept connections.
• Data Persistence: The sybase-data volume ensures your database state isn’t lost when the container restarts or is recreated.

Troubleshooting Quick Fixes #

If you still hit errors:

• Port Conflicts: Verify port 5000 isn’t used by another service on your host.
• Image Pull Issues: If the community image fails, try alternatives like datagrip/sybase-ase.
• Initialization Failures: Check container logs with docker-compose logs sybase—90% of issues are password-related or missing environment variables.
