📚 Llama Stack Deployment Script
|
||
|
||
Description:
|
||
This script sets up and deploys Llama Stack with Ollama integration in containers.
|
||
It handles both Docker and Podman runtimes and includes automatic platform detection.
|
||
|
||
Usage:
|
||
$(basename "$0") [OPTIONS]
|
||
|
||
Options:
|
||
-p, --port PORT Server port for Llama Stack (default: ${PORT})
|
||
-o, --ollama-port PORT Ollama service port (default: ${OLLAMA_PORT})
|
||
-m, --model MODEL Model alias to use (default: ${MODEL_ALIAS})
|
||
-i, --image IMAGE Server image (default: ${SERVER_IMAGE})
|
||
-t, --timeout SECONDS Service wait timeout in seconds (default: ${WAIT_TIMEOUT})
|
||
--with-telemetry Provision Jaeger, OTEL Collector, Prometheus, and Grafana (default: enabled)
|
||
--no-telemetry, --without-telemetry
|
||
Skip provisioning the telemetry stack
|
||
--telemetry-service NAME Service name reported to telemetry (default: ${TELEMETRY_SERVICE_NAME})
|
||
--telemetry-sinks SINKS Comma-separated telemetry sinks (default: ${TELEMETRY_SINKS})
|
||
--otel-endpoint URL OTLP endpoint provided to Llama Stack (default: ${OTEL_EXPORTER_OTLP_ENDPOINT})
