docker buildx inspect
| Description | Inspect current builder instance |
|---|---|
| Usage | docker buildx inspect [NAME] |
Description
Shows information about the current or specified builder.
Options
| Option | Default | Description |
|---|---|---|
--bootstrap | Ensure builder has booted before inspecting |
Examples
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's 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).
Override the configured builder instance (--builder)
Same as buildx --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:
NoteThe asterisk (
*) next to node build platform(s) indicate they have been manually set duringbuildx create. Otherwise the platforms were automatically detected.
