# Grafana MCP Server - Docker Compose deployment on Miranda
|
|
#
|
|
# Grafana itself runs inside the PPLG stack on Prospero (see docs/pplg.md).
|
|
# This playbook deploys the Grafana MCP server container on Miranda, which
|
|
# connects back to Grafana on Prospero via the internal Incus network.
|
|
#
|
|
# Prerequisites:
|
|
# - PPLG stack deployed on Prospero (ansible-playbook pplg/deploy.yml)
|
|
# - Grafana service account token in vault (vault_grafana_service_account_token)
|
|
# - Docker installed on the target host (ansible-playbook docker/deploy.yml)
|
|
#
|
|
# See also: docs/grafana_mcp.md
