Hello @Prashiratnam123, Is this error observed consistently?

Which region is your workspace on and when did this happen?

[Prashiratnam123]

Please help me to resolve( how to get the region details)

Hey @Prashiratnam123 

Could you provide more details on how you are trying to install the container?

1. Are you using a custom Docker image or a base Databricks container?

2.Are you mixing architectures (Graviton ARM vs. AMD64)? Some instances in AWS (like m6g, c7g) run on ARM architecture, which might not be compatible with AMD64-based Docker images.

3.Are there any errors in the cluster event logs? You can check the event logs in the Databricks UI under Clusters > Event Log to see if there are more details on why the container failed to launch.

If possible, please share the following details:

•The Docker image name and tag
•The Databricks runtime version
•The instance type you are using (m5, m6g, etc.)

This will help diagnose the issue faster. 🚀
