Add PROVIDER_HTTP_URL and PROVIDER_WS_URL to setup wizard

[Copilot]

Problem

The StarkNet staking package's entrypoint script requires PROVIDER_HTTP_URL and PROVIDER_WS_URL environment variables to connect to StarkNet full nodes (like Juno), but these were not configurable through the DAppNode setup wizard. Users could only rely on hardcoded values from the sepolia variant, making it impossible to customize provider endpoints for mainnet deployments.

# entrypoint.sh expects these variables but they weren't configurable
exec /app/validator \
  --provider-http "${PROVIDER_HTTP_URL}" \
  --provider-ws "${PROVIDER_WS_URL}" \
  # ... other args

Solution

This PR adds the missing provider URL configuration fields to the setup wizard, allowing users to specify their StarkNet full node endpoints during package installation.

Changes Made

setup-wizard.yml:

• Added provider_http_url field mapping to PROVIDER_HTTP_URL environment variable
• Added provider_ws_url field mapping to PROVIDER_WS_URL environment variable
• Both fields are required with sensible mainnet defaults (http://juno.public.dappnode:6070/v0_8 and ws://juno.public.dappnode:6071/v0_8)
• Clear descriptions explain each URL's purpose (blockchain data queries vs real-time updates)

docker-compose.yml:

• Added PROVIDER_HTTP_URL: "" and PROVIDER_WS_URL: "" environment variables to the staking service

Compatibility

The sepolia variant continues to work unchanged since it has its own docker-compose.yml with predefined URLs that override the setup wizard values. This ensures existing sepolia deployments are unaffected while enabling mainnet customization.

User Experience

Users will now see two additional setup fields during installation:

• StarkNet Provider HTTP URL: For querying blockchain data
• StarkNet Provider WebSocket URL: For real-time blockchain updates

Both fields come with working defaults but can be customized for different StarkNet full node configurations.

Original prompt

Add PROVIDER_HTTP_URL and
PROVIDER_WS_URL to the sutup wizard
