|
|
||||||
|
|
||||||
## Inline cache
|
|
||||||
|
|
||||||
In most cases you want to use the [`type=inline` cache exporter](https://github.com/docker/buildx/blob/master/docs/guides/cache/inline.md).
|
|
||||||
However, note that the `inline` cache exporter only supports `min` cache mode. To enable `max` cache mode, push the
|
|
||||||
image and the cache separately by using the `registry` cache exporter as shown in the [next example](#registry-cache).
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
name: ci
|
|
||||||
|
|
||||||
on:
|
|
||||||
push:
|
|
||||||
branches:
|
|
||||||
- 'main'
|
|
||||||
|
|
||||||
jobs:
|
|
||||||
docker:
|
|
||||||
runs-on: ubuntu-latest
|
|
||||||
steps:
|
|
||||||
-
|
|
||||||
name: Checkout
|
|
||||||
uses: actions/checkout@v3

|
||||||

|

|
|
||||||
cache-to: type=inline
|
|
||||||
```
|
|
||||||
|
|
||||||
## Registry cache
|
|
||||||
|
|
||||||
You can import/export cache from a cache manifest or (special) image configuration on the registry with the
|
|
||||||
[`type=registry` cache exporter](https://github.com/docker/buildx/blob/master/docs/guides/cache/registry.md).
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
name: ci
|
|
||||||
|
|
||||||
on:
|
|
||||||
push:
|
|
||||||

|
|
||||||
- 'main'
|
|
||||||
|
|
||||||

|
|

|

|
|
||||||
```
|

||||||
## GitHub cache
|
|
||||||
|
|
||||||
### Cache backend API
|
|
||||||
|
|
||||||
> **Warning**
|
|
||||||
>
|
|
||||||
> This cache exporter is considered EXPERIMENTAL until further notice. Please
|
|
||||||
> provide feedback on [BuildKit repository](https://github.com/moby/buildkit)
|
|
||||||
> if you encounter any issues.
|
|
||||||
|
|
||||||
[GitHub Actions cache exporter](https://github.com/docker/buildx/blob/master/docs/guides/cache/gha.md)
|
|
||||||
backend uses the [GitHub Cache API](https://github.com/tonistiigi/go-actions-cache/blob/master/api.md)
|
|
||||||
to fetch and upload cache blobs. That's why this type of cache should be
|
|
||||||
exclusively used in a GitHub Action workflow as the `url` (`$ACTIONS_CACHE_URL`)
|
|
||||||
and `token` (`$ACTIONS_RUNTIME_TOKEN`) attributes are populated when a workflow
|
|
||||||
is started.

### Local cache

# Named contexts

You can define [additional build contexts](https://docs.docker.com/engine/reference/commandline/buildx_build/#build-context)
|
This page has moved to [Docker Docs website](https://docs.docker.com/build/ci/github-actions/examples/#named-contexts)

that can be accessed in your Dockerfile with `FROM name` or `--from=name`. When
|
|
||||||
Dockerfile defines a stage with the same name it is overwritten.
|
|
||||||
|
|
||||||
This can be useful with GitHub Actions to reuse results from other builds or
|
|
||||||
pin an image to a spcific tag in your workflow.

||||||

|

## Pin image to a specific tag
|
|
||||||
|
|
||||||
Replace `alpine:latest` with a pinned one:
|
|
||||||
|
|
||||||
```dockerfile
|
|
||||||
# syntax=docker/dockerfile:1
|
|

alpine=docker-image://alpine:3.16
|
|
||||||
tags: myimage:latest
|
|
||||||
```
|
|
||||||
|
|
||||||
## Usage of the built image in other build steps
|
|
||||||
|
|
||||||
By default, the [`setup-buildx` action](https://github.com/docker/setup-buildx-action#about)
|
|
||||||
uses `docker-container` as a build driver, so built Docker images are not
|
|
||||||
available in the builder container.
|
|
||||||
|
|
||||||
With named contexts you can reuse the built image:
|
|
||||||
|
|
||||||
```dockerfile
|
|
||||||
# syntax=docker/dockerfile:1
|
|
||||||
FROM alpine
|
|
||||||
RUN echo "Hello World"
|
|
||||||
```

In the following example we will expose and use the [GITHUB_TOKEN secret](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#about-the-github_token-secret)
|
This page has moved to [Docker Docs website](https://docs.docker.com/build/ci/github-actions/examples/#secrets)
|
||||||
as provided by GitHub in your workflow.
|
|
||||||
|
|
||||||
First let's create our `Dockerfile` to use our secret:
|
|
||||||
|
|
||||||
```dockerfile
|
|
||||||
# syntax=docker/dockerfile:1
|
|
||||||
FROM alpine
|
|
||||||
RUN --mount=type=secret,id=github_token \
|
|
||||||
cat /run/secrets/github_token
|
|
||||||
```
|
|
||||||
|
|
||||||
As you can see we have named our secret `github_token`. Here is the workflow
|
|
||||||
you can use to expose this secret using the [`secrets` input](../../README.md#inputs):
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
name: ci
|
|
||||||
|
|
||||||
on:
|
|
||||||
push:
|
|
||||||
branches:
|
|
||||||
- 'main'
|
|
||||||
|
|
||||||
jobs:
|
|
||||||
docker:
|
|
||||||
runs-on: ubuntu-latest
|
|
||||||
steps:
|
|
||||||
-
|
|
||||||
name: Checkout
|
|

uses: actions/checkout@v3
|

|
|
||||||
tags: user/app:latest
|
|
||||||
secrets: |
|
|
||||||
"github_token=${{ secrets.GITHUB_TOKEN }}"
|
|
||||||
```
|
|
||||||
|
|
||||||
> **Note**
|
|
||||||
>
|
|
||||||
> You can also expose a secret file to the build with the [`secret-files`](../../README.md#inputs) input:
|
|
||||||
> ```yaml
|
|
||||||
> secret-files: |
|
|
||||||
> "MY_SECRET=./secret.txt"
|
|
||||||
> ```
|
|
||||||
|
|
||||||
If you're using [GitHub secrets](https://docs.github.com/en/actions/security-guides/encrypted-secrets)
|
|
||||||
and need to handle multi-line value, you will need to place the key-value pair
|
|
||||||
between quotes:
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
secrets: |
|
|
||||||
"MYSECRET=${{ secrets.GPG_KEY }}"
|
|
||||||
GIT_AUTH_TOKEN=abcdefghi,jklmno=0123456789
|
|
||||||
"MYSECRET=aaaaaaaa

||||||
bbbb
|
|
||||||
ccc"
|
|
||||||
"JSON_SECRET={""key1"":""value1"",""key2"":""value2""}"
|
|
||||||
```
|

If you want an "automatic" tag management and [OCI Image Format Specification](https://github.com/opencontainers/image-spec/blob/master/annotations.md)

This page has moved to [Docker Docs website](https://docs.docker.com/build/ci/github-actions/examples/#manage-tags-and-labels)
|

for labels, you can do it in a dedicated step. The following workflow will use
|
|
||||||
the [Docker metadata action](https://github.com/docker/metadata-action) to
|
|
||||||
handle tags and labels based on GitHub actions events and Git metadata:
|
|
||||||
|
|
||||||
```yaml

In some cases, you might want to validate that the image works as expected
