# 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://docs.docker.com/build/building/drivers/docker-container/)
|
|
(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: Checkout
|
|
uses: actions/checkout@v3
|
|
-
|
|
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: Checkout
|
|
uses: actions/checkout@v3
|
|
-
|
|
name: Set up Docker Buildx
|
|
uses: docker/setup-buildx-action@v2
|
|
with:
|
|
config: .github/buildkitd.toml
|
|
```
