Does anyone run Databricks jobs using Docker + ARM (Graviton) instances?

[ivanychev]

Graviton instances do not support Container services on paper (https://docs.databricks.com/clusters/graviton.html#unsupported-features) but if you try to build Docker ARM image and run it on Graviton, it will work. Does anyone use this combination in real life?

Graviton is not supported by Databricks Container Services. How are you planning to run it on Databricks?

Please tag @Debayan​ with your next comment so that I will get notified. Thank you!

@Debayan it is not supported but works. My question is if there's anyone who uses it

We're exploring ways to decrease EC2 costs. We use Docker for building images that are run in Databricks jobs. ARM instances seem like an obvious choice to look into, but it's weird that Databricks doesn't support it (because it works if you actually try to run a job on Graviton that uses a Docker image).
