Storing grafana dashboards

In grafana docker containers, one can predefine the data sources before initializing the container so that grafana will initiate directly knowing which to connect to.

Also can store the dashboards created manually in json format locally then mount it for grafana send time the container starts. You will see the dashboards directly on grafana once opened without creating dashboards again.

grafana:
	image: grafana/grafana:12.0.2-ubuntu
	container_name: grafana
	ports:
		- "3000:3000"
	volumes:
		- ./config/grafana_datasources.yml:/etc/grafana/provisioning/datasources/datasource.yaml:ro
		- ./config/grafana_dashboards.yml:/etc/grafana/provisioning/dashboards/dashboards.yaml:ro
		- ./dashboards:/opt/grafana/dashboards
	networks:
		- external-network
		- internal-network
	depends_on:
		postgres:
			condition: service_healthy

so typically you file system should have the following structure

config/
	grafana_datasources.yml
	grafana_dashboards.yml
dashboards/
	*.json # dashboards json files
