Use this skill for any bundle-related request including creating, configuring, validating, deploying, running, and managing Databricks resources through DABs.
Reference Documentation
The following reference files provide detailed guidance for specific bundle tasks:
- Bundle Structure - Bundle structure, databricks.yml configuration, resource definitions, path resolution, variables, and multi-environment targets
- SDP Pipelines - Spark Declarative Pipeline configurations for DABs
- SQL Alerts - SQL Alert schemas and configuration (critical - API differs from other resources)
- Deploy and Run - Validation, deployment, running resources, monitoring logs, and troubleshooting common issues
- Resource Permissions - Permission levels and access control for bundle resources, per-resource-type levels, grants vs permissions
When to Use This Skill
Load this skill for any request involving:
- Creating new bundle projects or resources
- Configuring databricks.yml or resource YAML files
- Setting up multi-environment deployments (dev/prod targets)
- Deploying or running bundle resources
- Managing permissions for bundle resources
- Troubleshooting bundle validation or deployment errors
- Working with specific resource types (dashboards, jobs, pipelines, alerts, volumes, apps)
General Guidelines
- Always validate after configuration changes - Use
bundle validate --strict --target <target>after any change - Use reference documentation - Consult the appropriate reference file for detailed patterns and examples
- Follow naming conventions - Resource files should use
<name>.<resource_type>.ymlformat - Path resolution is critical - Paths differ based on file location (see Bundle Structure reference)
- Preserve existing structure - Keep user comments and structure when editing YAML files
- Use variables - Parameterize catalog, schema, and warehouse for multi-environment support
- Namespace App names - App names are workspace-global and limited to 30 characters. With Databricks CLI 0.270.0 or later, shared-development defaults should include the app and
${workspace.current_user.domain_friendly_name}; override production with a stable name, and persist an explicit local value when the default is invalid, collides, or must distinguish multiple non-production targets in one workspace. On older CLI versions, require an explicitapp_namevalue instead
Required App Completion Contract
Before validating any bundle that creates or changes an App, re-read the final bundle YAML and confirm all of the following structural requirements:
- Each App resource uses a dedicated name variable, such as
name: ${var.app_name}, while preserving an existing equivalent variable when present. - For Databricks CLI 0.270.0 or later, each App name variable defaults to a recognizable App prefix plus
${workspace.current_user.domain_friendly_name}for development, and the production target overrides it with a stable name. On older CLI versions, App name variables have no default and each developer must provide values. - No development App name uses
${workspace.current_user.short_name}, a bare${bundle.target}, or a hardcoded value.
Only after this check, run databricks bundle validate --strict --target <target> --output json and inspect each resolved resources.apps.<key>.name. Each name must contain only lowercase letters, digits, and hyphens and be at most 30 characters. If a resolved name is invalid, collides after normalization, or multiple non-production targets share a workspace, persist a shorter, distinct value in the uncommitted .databricks/bundle/<target>/variable-overrides.json file and validate again. Successful validation alone does not satisfy this contract because validation does not catch every invalid or non-namespaced App name.
