GitHub Action to set up Docker [Buildx](https://github.com/docker/buildx).
|
||||
|
||||
This action will create and boot a builder that can be used in the following steps of your workflow if you're using
|
||||
[buildx](https://github.com/docker/buildx). By default, the `docker-container` [builder driver](https://github.com/docker/buildx/blob/master/docs/reference/buildx_create.md#driver)
|
||||
will be used to be able to build multi-platform images and export cache thanks to the [BuildKit](https://github.com/moby/buildkit)
|
||||
container.

### With QEMU

If you want support for more platforms you can use our [setup-qemu](https://github.com/docker/setup-qemu-action) action:

### Install by default
|
||||
## Advanced usage
|
||||
|
||||
If you want set up the `docker build` command as an alias to `docker buildx build`:
|
||||
|
||||
```yaml
|
||||
name: ci
|
||||
|
||||
on:
|
||||
push:
|
||||
|

jobs:
|

id: buildx
|

with:
|
||||
install: true
|
||||
-
|
||||
name: Build
|
||||
run: |
|
||||
docker build . # will run buildx
|
||||
```
|
||||
|
||||
### BuildKit daemon configuration
|
||||
|
||||
You can provide a [BuildKit configuration](https://github.com/moby/buildkit/blob/master/docs/buildkitd.toml.md)
|
||||
to your builder if you're using the [`docker-container` driver](https://github.com/docker/buildx/blob/master/docs/reference/buildx_create.md#driver)
|
||||
(default) with the `config` or `config-inline` inputs:
|
||||
|
||||
#### Registry mirror
|
||||
|
||||
You can configure a registry mirror using an inline block directly in your
|
||||
workflow with the `config-inline` input:
|
||||
|
||||
```yaml
|
||||
name: ci
|
||||
|
||||
on:
|
||||
push:
|
||||
|
||||
jobs:
|
||||
buildx:
|
||||
runs-on: ubuntu-latest
|
||||
steps:
|
||||
-
|
||||
name: Set up Docker Buildx
|
||||
uses: docker/setup-buildx-action@v2
|
||||
with:
|
||||
config-inline: |
|
||||
[registry."docker.io"]
|
||||
mirrors = ["mirror.gcr.io"]
|
||||
```
|
||||
|
||||
#### Max parallelism
|
||||
|
||||
You can limit the parallelism of the BuildKit solver which is particularly
|
||||
useful for low-powered machines.
|
||||
|
||||
You can use the `config-inline` input like the
|
||||
previous example, or you can use a dedicated BuildKit config file from your
|
||||
repo if you want with the `config` input:
|
||||
|
||||
```toml
|
||||
# .github/buildkitd.toml
|
||||
[worker.oci]
|
||||
max-parallelism = 4
|
||||
```
|
||||
|
||||
```yaml
|
||||
name: ci
|
||||
|
||||
on:
|
||||
push:
|
||||
|
||||
jobs:
|
||||
buildx:
|
||||
runs-on: ubuntu-latest
|
||||
steps:

||||

name: Set up Docker Buildx
|
||||
uses: docker/setup-buildx-action@v2
|
||||
with:
|
||||
config: .github/buildkitd.toml
|
||||
```
|
||||
|
||||
### Standalone mode
|
||||
|
||||
If you don't have the Docker CLI installed on the GitHub Runner, buildx binary
|
||||
is invoked directly, instead of calling it as a docker plugin. This can be
|
||||
useful if you want to use the `kubernetes` driver in your self-hosted runner:
|
||||
|
||||
```yaml
|
||||
name: ci
|
||||
|
||||
on:
|
||||
push:
|
