## Usage
|
## Usage
|
||||||
|
|
||||||
This action uses our [setup-buildx](https://github.com/docker/setup-buildx-action) action that extends the
|
By default, this action uses the [Git context](#git-context) so you don't need to use the
|
||||||
`docker build` command named [buildx](https://github.com/docker/buildx) with the full support of the features
|
[`actions/checkout`](https://github.com/actions/checkout/) action to checkout the repository because this will be
|
||||||
provided by [Moby BuildKit](https://github.com/moby/buildkit) builder toolkit. This includes multi-arch build,
|
done directly by buildkit. The git reference will be based on the [event that triggered your workflow](https://docs.github.com/en/actions/reference/events-that-trigger-workflows)
|
||||||
build-secrets, remote cache, etc. and different builder deployment/namespacing options.
|
and will result in the following context: `https://github.com/<owner>/<repo>.git#<ref>`.
|
||||||
|
|
||||||
|
Be careful because **any file mutation in the steps that precede the build step will be ignored** since
|
||||||
|
the context is based on the git reference. However, you can use the [Path context](#path-context) using the
|
||||||
|
[`context` input](#inputs) alongside the [`actions/checkout`](https://github.com/actions/checkout/) action to remove
|
||||||
|
this restriction.
|
||||||
|
|
||||||
|
In the examples below we are using 3 other actions:
|
||||||
|
|
||||||
|
* [`setup-buildx`](https://github.com/docker/setup-buildx-action) action will create and boot a builder using by
|
||||||
|
default the `docker-container` [builder driver](https://github.com/docker/buildx#--driver-driver). This is
|
||||||
|
**not required but recommended** using it to be able to build multi-platform images, export cache, etc.
|
||||||
|
* [`setup-qemu`](https://github.com/docker/setup-qemu-action) action can be useful if you want
|
||||||
|
to add emulation support with QEMU to be able to build against more platforms.
|
||||||
|
* [`login`](https://github.com/docker/setup-qemu-action) action will take care to log in against a Docker registry.

### Export image to Docker
|
|
||||||
|
|
||||||
You may want your build result to be available in the Docker client through `docker images` to be able to use it
|
|
||||||
in another step of your workflow:

### Leverage GitHub cache
|
|
||||||
|
|
||||||
You can leverage [GitHub cache](https://docs.github.com/en/actions/configuring-and-managing-workflows/caching-dependencies-to-speed-up-workflows)
|
|
||||||
using [actions/cache](https://github.com/actions/cache) with this action:

### Handle tags and labels
|
|
||||||
|
|
||||||
If you come from [`v1`](https://github.com/docker/build-push-action/tree/releases/v1#readme) and want an
|
|
||||||
"automatic" tag management and [OCI Image Format Specification](https://github.com/opencontainers/image-spec/blob/master/annotations.md)
|
|
||||||
for labels, you can do it in a dedicated step. The following workflow will use the [Docker meta action](https://github.com/crazy-max/ghaction-docker-meta)
|
|
||||||
to handle tags and labels based on GitHub actions events and Git metadata.

You can update the [DockerHub repository description](https://docs.docker.com/docker-hub/repos/) using

a third-party action called [DockerHub Description](https://github.com/peter-evans/dockerhub-description)

### Multi-line secret value
|
|
||||||
|
|
||||||
To handle multi-line value for a secret, you will need to place the key-value pair between quotes:

||||||
|
|
||||||
```yaml
|
|
||||||
secrets: |
|
|
||||||
"MYSECRET=${{ secrets.GPG_KEY }}"

# Secrets
|
||||||
|
|
||||||
|
In the following example we will expose and use the [GITHUB_TOKEN secret](https://docs.github.com/en/actions/reference/authentication-in-a-workflow#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:1.2
|
||||||
|
|
||||||
|
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:
|
||||||
|
- 'master'
|
||||||
|
|
||||||
|
jobs:
|
||||||
|
docker:
|
||||||
|
runs-on: ubuntu-latest
|
||||||
|
steps:
|
||||||
|
-
|
||||||
|
name: Checkout
|
||||||
|
uses: actions/checkout@v2
|
||||||
|
-
|
||||||
|
name: Set up QEMU
|
||||||
|
uses: docker/setup-qemu-action@v1
|
||||||
|
-
|
||||||
|
name: Set up Docker Buildx
|
||||||
|
uses: docker/setup-buildx-action@v1
|
||||||
|
-
|
||||||
|
name: Build
|
||||||
|
uses: docker/build-push-action@v2
|
||||||
|
with:
|
||||||
|
context: .
|
||||||
|
platforms: linux/amd64,linux/arm64
|
||||||
|
tags: user/app:latest
|
||||||
|
secrets: |
|
||||||
|
"github_token=${{ secrets.GITHUB_TOKEN }}"
|
||||||
|
```
|
||||||
|
|
||||||
|
> :bulb: You can also expose a secret file to the build with [`secret-files`](../../README.md#inputs) input:
|
||||||
|
> ```yaml
|
||||||
|
> secret-files: |
|
||||||
|
> "MY_SECRET=./secret.txt"
|
||||||
|
> ```
|
||||||
|
|
||||||
|
If you're using [GitHub secrets](https://docs.github.com/en/actions/reference/encrypted-secrets) and need to handle
|
||||||
|
multi-line value, you will need to place the key-value pair between quotes:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
secrets: |
|
||||||
|
"MYSECRET=${{ secrets.GPG_KEY }}"
|
||||||
|
GIT_AUTH_TOKEN=abcdefghi,jklmno=0123456789
|
||||||
|
"MYSECRET=aaaaaaaa
|
||||||
|
bbbbbbb
|
||||||
|
ccccccccc"
|
||||||
|
FOO=bar
|
||||||
|
"EMPTYLINE=aaaa
|
||||||
|
|
||||||
|
bbbb
|
||||||
|
ccc"
|
||||||
|
"JSON_SECRET={""key1"":""value1"",""key2"":""value2""}"
|
||||||
|
```
|
||||||
|
|
||||||
|
| Key | Value |
|
||||||
|
|--------------------|--------------------------------------------------|
|
||||||
|
| `MYSECRET` | `***********************` |
|
||||||
|
| `GIT_AUTH_TOKEN` | `abcdefghi,jklmno=0123456789` |
|
||||||
|
| `MYSECRET` | `aaaaaaaa\nbbbbbbb\nccccccccc` |
|
||||||
|
| `FOO` | `bar` |
|
||||||
|
| `EMPTYLINE` | `aaaa\n\nbbbb\nccc` |
|
||||||
|
| `JSON_SECRET` | `{"key1":"value1","key2":"value2"}` |
|
||||||
|
|
||||||
|
> :bulb: All quote signs need to be doubled for escaping.

# Handle tags and labels
|
||||||
|
|
||||||
|
If you come from [`v1`](https://github.com/docker/build-push-action/tree/releases/v1#readme) and want an
|
||||||
|
"automatic" tag management and [OCI Image Format Specification](https://github.com/opencontainers/image-spec/blob/master/annotations.md)
|
||||||
|
for labels, you can do it in a dedicated step. The following workflow will use the [Docker meta action](https://github.com/crazy-max/ghaction-docker-meta)
|
||||||
|
to handle tags and labels based on GitHub actions events and Git metadata.
