NAME¶

docker-buildx-ls - List builder instances

SYNOPSIS¶

docker buildx ls

DESCRIPTION¶

Lists all builder instances and the nodes for each instance.

$ 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.

OPTIONS¶

--format="table" Format the output

-h, --help[=false] help for ls

EXAMPLE¶

### Format the output (--format) {#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:

$ 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

```
