Name

aspire doctor - Check the Aspire development environment for common issues.

Synopsis

aspire doctor [options]

Description

The aspire doctor command runs a series of diagnostic checks to verify that your development environment is properly configured for Aspire development. It checks prerequisites such as the .NET SDK, container runtime, and environment settings.

This command is useful for troubleshooting when you encounter issues with Aspire or when setting up a new development environment. The checks are grouped by category:

SDK checks: Verifies .NET SDK installation and version requirements
Container checks: Validates container runtime (Docker/Podman) availability and configuration
Environment checks: Validates environment variables and other settings

The command displays results with clear status indicators:

✓ (green) - Check passed
⚠ (yellow) - Warning (non-blocking issue)
✗ (red) - Check failed (blocking issue)

If any checks fail, the command provides suggestions for how to fix the issues and links to relevant documentation.

The following options are available:

--json

Outputs the check results in JSON format. This is useful for automation scenarios or when you need to parse the results programmatically.
-?, -h, --help

Prints help and usage documentation for the available commands and options.
-d, --debug

Enable debug logging to the console, which prints detailed information about what Aspire CLI is doing when a command is run.
--wait-for-debugger
