| > for more details about cache storage backends. | ||||
| 
 | ||||
| ## 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 | ||||
|       - | ||||
|         name: Set up Docker Buildx | ||||
|         uses: docker/setup-buildx-action@v2 | ||||
|       - | ||||
|         name: Login to Docker Hub | ||||
|         uses: docker/login-action@v2 | ||||
|         with: | ||||
|           username: ${{ secrets.DOCKERHUB_USERNAME }} | ||||
|           password: ${{ secrets.DOCKERHUB_TOKEN }} | ||||
|       - | ||||
|         name: Build and push | ||||
|         uses: docker/build-push-action@v3 | ||||
|         with: | ||||
|           context: . | ||||
|           push: true | ||||
|           tags: user/app:latest | ||||
|           cache-from: type=registry,ref=user/app:latest | ||||
|           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: | ||||
|     branches: | ||||
|       - 'main' | ||||
| 
 | ||||
| jobs: | ||||
|   docker: | ||||
|     runs-on: ubuntu-latest | ||||
|     steps: | ||||
|       - | ||||
|         name: Checkout | ||||
|         uses: actions/checkout@v3 | ||||
|       - | ||||
|         name: Set up Docker Buildx | ||||
|         uses: docker/setup-buildx-action@v2 | ||||
|       - | ||||
|         name: Login to Docker Hub | ||||
|         uses: docker/login-action@v2 | ||||
|         with: | ||||
|           username: ${{ secrets.DOCKERHUB_USERNAME }} | ||||
|           password: ${{ secrets.DOCKERHUB_TOKEN }} | ||||
|       - | ||||
|         name: Build and push | ||||
|         uses: docker/build-push-action@v3 | ||||
|         with: | ||||
|           context: . | ||||
|           push: true | ||||
|           tags: user/app:latest | ||||
|           cache-from: type=registry,ref=user/app:buildcache | ||||
|           cache-to: type=registry,ref=user/app:buildcache,mode=max | ||||
| ``` | ||||
| 
 | ||||
| ## GitHub cache | ||||
| 
 | ||||
| ### Cache backend API | ||||
| 
 | ||||
| > **Warning** | ||||
| > | ||||
| > This cache exporter is considered EXPERIMENTAL until further notice. Please | ||||
| > provide feedback on [BuildKit repository](https://github.com/moby/buildkit) | ||||
| > if you encounter any issues. | ||||
| 
 | ||||
| [GitHub Actions cache exporter](https://github.com/docker/buildx/blob/master/docs/guides/cache/gha.md) | ||||
| backend uses the [GitHub Cache API](https://github.com/tonistiigi/go-actions-cache/blob/master/api.md) | ||||
| to fetch and upload cache blobs. That's why this type of cache should be | ||||
| exclusively used in a GitHub Action workflow as the `url` (`$ACTIONS_CACHE_URL`) | ||||
| and `token` (`$ACTIONS_RUNTIME_TOKEN`) attributes are populated when a workflow | ||||
| is started. | ||||
| 
 | ||||
| ```yaml | ||||
| name: ci | ||||
| 
 | ||||
| on: | ||||
|   push: | ||||
|     branches: | ||||
|       - 'main' | ||||
| 
 | ||||
| jobs: | ||||
|   docker: | ||||
|     runs-on: ubuntu-latest | ||||
|     steps: | ||||
|       - | ||||
|         name: Checkout | ||||
|         uses: actions/checkout@v3 | ||||
|       - | ||||
|         name: Set up Docker Buildx | ||||
|         uses: docker/setup-buildx-action@v2 | ||||
|       - | ||||
|         name: Login to Docker Hub | ||||
|         uses: docker/login-action@v2 | ||||
|         with: | ||||
|           username: ${{ secrets.DOCKERHUB_USERNAME }} | ||||
|           password: ${{ secrets.DOCKERHUB_TOKEN }} | ||||
|       - | ||||
|         name: Build and push | ||||
|         uses: docker/build-push-action@v3 | ||||
|         with: | ||||
|           context: . | ||||
|           push: true | ||||
|           tags: user/app:latest | ||||
|           cache-from: type=gha | ||||
|           cache-to: type=gha,mode=max | ||||
| ``` | ||||
| 
 | ||||
| ### Local cache | ||||
| 
 | ||||
| > **Warning** | ||||
| > | ||||
| > At the moment caches are copied over the existing cache, so it [keeps growing](https://github.com/docker/build-push-action/issues/252). | ||||
| > The `Move cache` step is used as a workaround (see [moby/buildkit#1896](https://github.com/moby/buildkit/issues/1896) for more info). | ||||
| 
 | ||||
| You can also leverage [GitHub cache](https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows) | ||||
| using the [actions/cache](https://github.com/actions/cache) and [`type=local` cache exporter](https://github.com/docker/buildx/blob/master/docs/guides/cache/local.md) | ||||

| # Named contexts | ||||
| 
 | ||||
| You can define [additional build contexts](https://docs.docker.com/engine/reference/commandline/buildx_build/#build-context) | ||||
| 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](#pin-image-to-a-specific-tag) | ||||
| * [Usage of the built image in other build steps](#usage-of-the-built-image-in-other-build-steps) | ||||
| 
 | ||||
| ## Pin image to a specific tag | ||||
| 
 | ||||
| Replace `alpine:latest` with a pinned one: | ||||
| 
 | ||||
| ```dockerfile | ||||
| # syntax=docker/dockerfile:1 | ||||
| FROM alpine | ||||
| RUN echo "Hello World" | ||||
| ``` | ||||
|

|             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" | ||||
| ``` | ||||

| # Secrets | ||||
| 
 | ||||
| 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) | ||||
| 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 | ||||
|       - | ||||
|         name: Set up QEMU | ||||
|         uses: docker/setup-qemu-action@v2 | ||||

|         uses: docker/setup-buildx-action@v2 | ||||

|         uses: docker/build-push-action@v3 | ||||
|         with: | ||||
|           context: . | ||||
|           platforms: linux/amd64,linux/arm64 | ||||
|           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""}" | ||||
| ``` | ||||
| 
 | ||||
| | Key                | Value                               | | ||||
| |--------------------|-------------------------------------| | ||||

| # Test your image before pushing it | ||||
| 
 | ||||
| In some cases, you might want to validate that the image works as expected | ||||
| before pushing it. | ||||
| 
 | ||||
| The workflow below will be composed of several steps to achieve this: | ||||
| * Build and export the image to Docker | ||||
| * Test your image | ||||
| * Multi-platform build and push the image | ||||
| 
 | ||||
| ```yaml | ||||
| name: ci | ||||
| 
 | ||||
| on: | ||||
|   push: | ||||
|     branches: | ||||
|       - 'main' | ||||
| 
 | ||||
| env: | ||||
|   TEST_TAG: user/app:test | ||||
|   LATEST_TAG: user/app:latest | ||||
| 
 | ||||
| jobs: | ||||
|   docker: | ||||
|     runs-on: ubuntu-latest | ||||
|     steps: | ||||
|       - | ||||
|         name: Checkout | ||||
|         uses: actions/checkout@v3 | ||||
|       - | ||||
|         name: Set up QEMU | ||||
|         uses: docker/setup-qemu-action@v2 | ||||
|       - | ||||
|         name: Set up Docker Buildx | ||||
|         uses: docker/setup-buildx-action@v2 | ||||
|       - | ||||
|         name: Login to Docker Hub | ||||
|         uses: docker/login-action@v2 | ||||
|         with: | ||||
|           username: ${{ secrets.DOCKERHUB_USERNAME }} | ||||
|           password: ${{ secrets.DOCKERHUB_TOKEN }} | ||||
|       - | ||||
|         name: Build and export to Docker | ||||
|         uses: docker/build-push-action@v3 | ||||
|         with: | ||||
|           context: . | ||||
|           load: true | ||||
|           tags: ${{ env.TEST_TAG }} | ||||
|       - | ||||
|         name: Test | ||||
|         run: | | ||||
|           docker run --rm ${{ env.TEST_TAG }} | ||||
|       - | ||||
|         name: Build and push | ||||
|         uses: docker/build-push-action@v3 | ||||
|         with: | ||||
|           context: . | ||||
|           platforms: linux/amd64,linux/arm64 | ||||
|           push: true | ||||
|           tags: ${{ env.LATEST_TAG }} | ||||
| ``` | ||||
| 
 | ||||
| > **Note** | ||||
| > | ||||
| > Build time will not be increased with this workflow because internal cache | ||||
| > for `linux/amd64` will be used from previous step on `Build and push` step | ||||
| > so only `linux/arm64` will be actually built. | ||||
