## Description

Shows information about the current or specified builder.

## Examples

### <a name="bootstrap"></a> Ensure that the builder is running before inspecting (--bootstrap)

Use the `--bootstrap` option to ensure that the builder is running before
inspecting it. If the driver is `docker-container`, then `--bootstrap` starts
the buildkit container and waits until it is operational. Bootstrapping is
automatically done during build, and therefore not necessary. The same BuildKit
container is used during the lifetime of the associated builder node (as
displayed in `buildx ls`).

### <a name="builder"></a> Override the configured builder instance (--builder)

Same as [`buildx --builder`](buildx.md#builder).

### Get information about a builder instance

By default, `inspect` shows information about the current builder. Specify the
name of the builder to inspect to get information about that builder.
The following example shows information about a builder instance named
`elated_tesla`:

> **Note**

> Asterisk `*` next to node build platform(s) indicate they had been set manually during `buildx create`. Otherwise, it had been autodetected.
