# buildx ls
```text
docker buildx ls
```
<!---MARKER_GEN_START-->
List builder instances
### Options
| Name | Type | Default | Description |
|:----------------------|:---------|:--------|:------------------|
| [`--format`](#format) | `string` | `table` | Format the output |
<!---MARKER_GEN_END-->
## Description
Lists all builder instances and the nodes for each instance.
```console
$ docker buildx ls
NAME/NODE DRIVER/ENDPOINT STATUS BUILDKIT PLATFORMS
elated_tesla* docker-container
\_ elated_tesla0 \_ unix:///var/run/docker.sock running v0.10.3 linux/amd64
\_ elated_tesla1 \_ ssh://ubuntu@1.2.3.4 running v0.10.3 linux/arm64*, linux/arm/v7, linux/arm/v6
default docker
\_ default \_ default running v0.8.2 linux/amd64
```
Each builder has one or more nodes associated with it. The current builder's
name is marked with a `*` in `NAME/NODE` and explicit node to build against for
the target platform marked with a `*` in the `PLATFORMS` column.
## Examples
### <a name="format"></a> Format the output (--format)
The formatting options (`--format`) pretty-prints builder instances output
using a Go template.
Valid placeholders for the Go template are listed below:
| Placeholder | Description |
|-------------------|---------------------------------------------|
| `.Name` | Builder or node name |
| `.DriverEndpoint` | Driver (for builder) or Endpoint (for node) |
| `.LastActivity` | Builder last activity |
| `.Status` | Builder or node status |
| `.Buildkit` | BuildKit version of the node |
| `.Platforms` | Available node's platforms |
| `.Error` | Error |
| `.Builder` | Builder object |
When using the `--format` option, the `ls` command will either output the data
exactly as the template declares or, when using the `table` directive, includes
column headers as well.
The following example uses a template without headers and outputs the
`Name` and `DriverEndpoint` entries separated by a colon (`:`):
```console
$ docker buildx ls --format "{{.Name}}: {{.DriverEndpoint}}"
elated_tesla: docker-container
elated_tesla0: unix:///var/run/docker.sock
elated_tesla1: ssh://ubuntu@1.2.3.4
default: docker
default: default
```
The `Builder` placeholder can be used to access the builder object and its
fields. For example, the following template outputs the builder's and
nodes' names with their respective endpoints:
```console
$ docker buildx ls --format "{{.Builder.Name}}: {{range .Builder.Nodes}}\n {{.Name}}: {{.Endpoint}}{{end}}"
elated_tesla:
elated_tesla0: unix:///var/run/docker.sock
elated_tesla1: ssh://ubuntu@1.2.3.4
default: docker
default: default
```
