buildx inspect

Usage:  docker buildx inspect [NAME]

Inspect current builder instance

Options:
      --bootstrap        Ensure builder has booted before inspecting
      --builder string   Override the configured builder instance

Description

Shows information about the current or specified builder.

Examples

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:

$ docker buildx inspect elated_tesla

Name:   elated_tesla
Driver: docker-container

Nodes:
Name:      elated_tesla0
Endpoint:  unix:///var/run/docker.sock
Status:    running
Platforms: linux/amd64

Name:      elated_tesla1
Endpoint:  ssh://ubuntu@1.2.3.4
Status:    running
Platforms: linux/arm64, linux/arm/v7, linux/arm/v6

Ensure that the builder is running before inspecting (--bootstrap)

Use the --bootstrap option to ensures 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, it is thus not necessary. The same BuildKit container is used during the lifetime of the associated builder node (as displayed in buildx ls).
