### BuildKit container logs
|
||||
|
||||
To display BuildKit container logs (when `docker-container` driver is used) you have to [enable step debug logging](https://docs.github.com/en/actions/managing-workflow-runs/enabling-debug-logging#enabling-step-debug-logging),
|
||||
or you can also enable debugging in the [setup-buildx action step](https://github.com/docker/setup-buildx-action):

## Keep up-to-date with GitHub Dependabot
|

|

Since [Dependabot](https://docs.github.com/en/github/administering-a-repository/keeping-your-actions-up-to-date-with-github-dependabot)
|
||||
has [native GitHub Actions support](https://docs.github.com/en/github/administering-a-repository/configuration-options-for-dependency-updates#package-ecosystem),
|
||||
to enable it on your GitHub repo all you need to do is add the `.github/dependabot.yml` file:
|
||||
|
||||
```yaml
|
||||
version: 2
|
||||
updates:
|
||||
# Maintain dependencies for GitHub Actions
|
||||
- package-ecosystem: "github-actions"
|
||||
directory: "/"

# Append additional nodes to the builder
|
||||
|
||||
Buildx also supports running builds on multiple machines. This is useful for
|
||||
building [multi-platform images](https://docs.docker.com/build/building/multi-platform/)
|
||||
on native nodes for more complicated cases that are not handled by QEMU and
|
||||
generally have better performance or for distributing the build across multiple
|
||||
machines.
|
||||
|
||||
You can append nodes to the builder that is going to be created with the
|
||||
`append` input in the form of a YAML string document to remove limitations
|
||||
intrinsically linked to GitHub Actions (only string format is handled in the
|
||||
input fields):
|
||||
|
||||
| Name | Type | Description |
|
||||
|-------------------|--------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
||||
| `name` | String | [Name of the node](https://docs.docker.com/engine/reference/commandline/buildx_create/#node). If empty, it is the name of the builder it belongs to, with an index number suffix. This is useful to set it if you want to modify/remove a node in an underlying step of you workflow. |
|
||||
| `endpoint` | String | [Docker context or endpoint](https://docs.docker.com/engine/reference/commandline/buildx_create/#description) of the node to add to the builder |
|
||||
| `driver-opts` | List | List of additional [driver-specific options](https://docs.docker.com/engine/reference/commandline/buildx_create/#driver-opt) |
|
||||
| `buildkitd-flags` | String | [Flags for buildkitd](https://docs.docker.com/engine/reference/commandline/buildx_create/#buildkitd-flags) daemon |
|
||||
| `platforms` | String | Fixed [platforms](https://docs.docker.com/engine/reference/commandline/buildx_create/#platform) for the node. If not empty, values take priority over the detected ones. |
|
||||

# Authentication support
|
||||
|
||||
## SSH authentication
|
||||
|
||||
To be able to connect to an SSH endpoint using the [`docker-container` driver](https://docs.docker.com/build/building/drivers/docker-container/),
|
||||
you have to set up the SSH private key and configuration on the GitHub Runner:
|
||||
|
||||
```yaml
|
||||
name: ci
|
||||
|
||||
on:
|
||||
push:
|
||||
|
||||
jobs:
|
||||

||||

|
||||
with:
|
||||
host: graviton2
|
||||
private-key: ${{ secrets.SSH_PRIVATE_KEY }}
|
||||
private-key-name: aws_graviton2
|
||||
-
|

name: Set up Docker Buildx
|
||||
uses: docker/setup-buildx-action@v2
|
||||
with:
|
||||
endpoint: ssh://me@graviton2
|
||||
```
|
||||
|
||||
## TLS authentication
|
||||
|
||||
You can also [set up a remote BuildKit instance](https://docs.docker.com/build/building/drivers/remote/#remote-buildkit-in-docker-container)
|
||||
using the remote driver. To ease the integration in your workflow, we put in
|
||||
place environment variables that will set up authentication using the BuildKit
|
||||
client certificates for the `tcp://` endpoint where `<idx>` is the position of
|
||||
the node in the list of nodes:
|
||||
|
||||
* `BUILDER_NODE_<idx>_AUTH_TLS_CACERT`
|
||||
* `BUILDER_NODE_<idx>_AUTH_TLS_CERT`
|
||||
* `BUILDER_NODE_<idx>_AUTH_TLS_KEY`
|
||||
|
||||
```yaml
|
||||
name: ci
|
||||
|
||||
on:
|
||||
push:
|
||||

# 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

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
|
||||
```

||||

||||
