aspire describe command

Name

aspire describe - Describe resources in a running AppHost.

Synopsis

Aspire CLI

aspire describe [<resource>] [options]

Description

The aspire describe command displays resource details for a running Aspire AppHost. By default, it shows a snapshot table of all resources with their name, type, state, health status, and endpoints. Use the --follow option to continuously stream resource state changes in real time.

When a specific resource name is provided, only matching resources are displayed. If no matching resource is found, the command returns an error.

When executed without the --apphost option, the command:

1. Scans for all running AppHost processes.
2. If multiple AppHosts are running within the current directory scope, prompts you to select which one to target.
3. If only one AppHost is running in scope, connects to it directly.
4. If no in-scope AppHosts are found but out-of-scope AppHosts exist, displays all running AppHosts for selection.

ヒント

The aspire resources command is a backward-compatible alias for aspire describe. Both names invoke the same command.

Arguments

• <resource>

  The name of the resource to display. If not specified, all resources are shown.

Options

The following options are available:

• -f, --follow

  Continuously stream resource state changes. In table mode, each update prints a line showing the resource name, state, health, and endpoints. In JSON mode, each update emits a single JSON object per line (Newline Delimited JSON (NDJSON) format).

• --apphost <path>

  The path to the Aspire AppHost project file. When specified, the command connects to the AppHost running from that project file without prompting for selection.

• --format <Json|Table>

  Output format. Use Json for machine-readable output suitable for scripting and automation. Defaults to Table. Values are case-insensitive.

  In snapshot mode (without --follow), JSON output wraps resources in a { "resources": [...] } object. In follow mode, JSON output uses Newline Delimited JSON (NDJSON) for streaming, emitting one JSON object per line.

• -?, -h, --help

  Prints help and usage documentation for the available commands and options.

• -l, --log-level <Critical|Debug|Error|Information|None|Trace|Warning>

  Set the minimum log level for console output. Use this option to increase diagnostics while troubleshooting or reduce output in scripted runs.

• --non-interactive

  Run the command in non-interactive mode, disabling all interactive prompts and spinners.

• --nologo

  Suppress the startup banner and telemetry notice.

• --banner

  Display the animated Aspire CLI welcome banner.

• --wait-for-debugger

  Wait for a debugger to attach before running a command.
