How to build and run the Spark dashboard in a container image

How to run

Run the dashboard using a container image from Dockerhub:

• There are a few ports needed and multiple options on how to expose them
• Port 2003 is for Graphite ingestion, port 3000 is for Grafana, port 8428 is used internally by VictoriaMetrics source
• You can expose the ports from the container individually or just make network=host.
• Examples:

docker run --network=host -d lucacanali/spark-dashboard
or
docker run -p 3000:3000 -p 2003:2003 -d lucacanali/spark-dashboard
or
docker run -p 3000:3000 -p 2003:2003 -p 8428:8428 -d lucacanali/spark-dashboard

Advanced: persist InfluxDB data across restarts

• This shows an example of how to use a volume to store data on VictoriaMetrics. It allows preserving the history across runs when the container is restarted, otherwise InfluxDB starts from scratch each time.

mkdir metrics_data
docker run --network=host -v ./metrics_data:/victoria-metrics-data -d lucacanali/spark-dashboard:v02

Example of how to build the image:

cd dockerfiles_v2
docker build -t spark-dashboard:v02 .
