⁠Sling Platform Docker Image

The slingdata/sling-platform image provides a self-hosted Sling data platform for managing data pipelines, connections, and agents.

See for more details:

⁠Quick Start

Run below and access on http://localhost:7878⁠:

docker run -d \
  -p 7878:7878 \  # this is the HTTP port
  -p 4443:4443 \  # NATS port for agent communication
  -e SLING_PLATFORM_LICENSE="your-license-key" \
  -e SLING_PLATFORM_ENCRYPTION_KEY="your-32-char-encryption-key" \
  -e SLING_PLATFORM_ADMIN_CREDENTIALS='{"email":"[email protected]","password":"your-secure-password"}' \
  -v sling-platform-data:/home/sling \
  slingdata/sling-platform:latest

⁠Required Environment Variables

SLING_PLATFORM_LICENSE - Your Sling Platform license key. This can be either a 36-character UUID for cloud-verified licenses or an offline license token for air-gapped environments.
SLING_PLATFORM_ENCRYPTION_KEY - A 32-character encryption key used to encrypt sensitive data like connection credentials. Generate a secure random string.
SLING_PLATFORM_ADMIN_CREDENTIALS - JSON payload containing the initial admin user credentials. need email and password keys.

⁠Optional Environment Variables

SLING_PLATFORM_HOST - The external URL where your platform will be accessible. This is used for agent connections and web UI access. The default is http://localhost:7878
SLING_PLATFORM_SMTP_CREDENTIALS - SMTP configuration for email notifications. If not provided, email notifications will be disabled. For example: {"host":"smtp.gmail.com","port":587,"user":"[email protected]","password":"your-app-password","from":"Sling Platform <[email protected]>"}

⁠Connecting Agents

To connect Sling agents to your platform, use the slingdata/sling image with these environment variables:

docker run -d \
  -e SLING_PLATFORM_HOST="http://your-platform-host:7878" \
  -e SLING_AGENT_KEY="your-agent-key-from-platform-ui" \
  -v sling-agent-data:/home/sling \
  slingdata/sling agent run

⁠Agent Environment Variables

SLING_AGENT_KEY - Agent authentication key obtained from the platform UI under Agents section
SLING_PLATFORM_HOST - Same URL as your platform instance
SLING_PLATFORM_HOST_WS - Optional, the web-socket host to use for NATS connection, e.g. ws://your-platform-host:4443. Default uses the same host as SLING_PLATFORM_HOST.

⁠Docker Compose Example

services:
  sling-platform:
    image: slingdata/sling-platform
    ports:
      - "7878:7878"  # HTTP port for UI and API
      - "4443:4443"  # NATS WebSocket port for agent communication
    expose:
      - "7878"
      - "4443"
    environment:
      SLING_PLATFORM_LICENSE: "your-license-key"
      SLING_PLATFORM_ENCRYPTION_KEY: "your-32-char-encryption-key"
      SLING_PLATFORM_ADMIN_CREDENTIALS: '{"email":"[email protected]","password":"secure-password"}'
      SLING_PLATFORM_HOST: "http://external.ip:7878"  # External URL for web UI access
      SLING_PLATFORM_SMTP_CREDENTIALS: '{"host":"smtp.gmail.com","port":587,"user":"your-email","password":"your-password","from":"Sling <[email protected]>"}'
    volumes:
      - sling-platform-data:/home/sling
    restart: unless-stopped

  sling-agent:
    image: slingdata/sling:latest
    environment:
      SLING_PLATFORM_HOST: "http://sling-platform:7878"  # Internal container communication
      SLING_AGENT_KEY: "your-agent-key"
    command: agent run
    volumes:
      - sling-agent-data:/home/sling
    depends_on:
      - sling-platform
    restart: unless-stopped

volumes:
  sling-platform-data:
  sling-agent-data:

⁠Ports

7878 - Main HTTP port for web UI and API access
4443 - Web-Socket port for agent communication (via NATS)

⁠Volumes

/home/sling - Platform data directory.

⁠Getting Started

Start the platform container with required environment variables
Access the web UI at your configured SLING_PLATFORM_HOST
Log in with your admin credentials
Create agent keys in the Agents section
Deploy agents using the slingdata/sling image
Start creating connections and data pipelines

⁠Security Notes

Use strong, unique values for SLING_PLATFORM_ENCRYPTION_KEY
Store sensitive environment variables securely
Use HTTPS in production environments
Regularly update your license and credentials
Ensure proper network security for agent communications
