Docker-MySQL-NodeRED-Grafana

Docker stack with persistent data volumes for IoT data logging projects.

The init folders contain first run configurations where necessary, MySQL users, schema, Grafana datasource etc.

Use as template

The docker-compose.yml file may be used as a template for other projects. In this case make sure to:

• Clean up the init volumes definitions in docker-compose.yml.
• Create volumes before first docker-compose up to avoid permission issues

Once the containers are successfully built and running:

• Create schema and table in MySQL workbench

• Set MySQL datasource IP in Grafana.

• Secure NodeRED

Setting NodeRED admin password:

Create and copy hashed password

docker exec -it nodered npx node-red admin hash-pw

docker-compose stop node-red

Uncomment the adminAuth section in settings.js and paste the hashed password.

Start NodeRED

docker-compose start node-red

MySQL node tips

Install node-red-contrib-stackhero-mysql to avoid ER_NOT_SUPPORTED_AUTH_MODE error.

Import .json flow containing example INSERT function.
