## Upgrade from v1
|
|
|
|
`v2` of this action includes significant updates and now uses Docker [Buildx](https://github.com/docker/buildx). It
|
|
works with 3 new actions ([login](https://github.com/docker/login-action), [setup-buildx](https://github.com/docker/setup-buildx-action)
|
|
and [setup-qemu](https://github.com/docker/setup-qemu-action)) that we have created. It's also rewritten as a
|
|
[typescript-action](https://github.com/actions/typescript-action/) to be as closed as possible of the
|
|
[GitHub Runner](https://github.com/actions/virtual-environments) during its execution.
|
|
|
|
[Upgrade notes](UPGRADE.md) and many [usage examples](#usage) have been added to handle most use cases but `v1` is
|
|
still available through [`releases/v1` branch](https://github.com/docker/build-push-action/tree/releases/v1).
|
|
|
|

## Usage
|
|
|
|
This action uses our [setup-buildx](https://github.com/docker/setup-buildx-action) action that extends the
|
|
`docker build` command named [buildx](https://github.com/docker/buildx) with the full support of the features
|
|
provided by [Moby BuildKit](https://github.com/moby/buildkit) builder toolkit. This includes multi-arch build,
|
|
build-secrets, remote cache, etc. and different builder deployment/namespacing options.
|
|
|
|
### Git context
|
|
|
|
The default behavior of this action is to use the Git context invoked by your workflow.
|
|
(eg. `https://github.com/<owner>/<repo>.git#<ref>`)
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: master
|
|
|
|
jobs:
|
|
main:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Set up QEMU
|
|
uses: docker/setup-qemu-action@v1
|
|
-
|
|
name: Set up Docker Buildx
|
|
uses: docker/setup-buildx-action@v1
|
|
-
|
|
name: Login to DockerHub
|
|
uses: docker/login-action@v1
|
|
with:
|
|
username: ${{ secrets.DOCKERHUB_USERNAME }}
|
|
password: ${{ secrets.DOCKERHUB_TOKEN }}
|
|
-
|
|
name: Build and push
|
|
id: docker_build
|
|
uses: docker/build-push-action@v2
|
|
with:
|
|
push: true
|
|
tags: user/app:latest
|
|
build-args: |
|
|
arg1=value1
|
|
arg2=value2
|
|
-
|
|
name: Image digest
|
|
run: echo ${{ steps.docker_build.outputs.digest }}
|
|
```
|
|
|
|
Building from current repository automatically uses the [GitHub Token](https://help.github.com/en/actions/configuring-and-managing-workflows/authenticating-with-the-github_token)
|
|
as provided by `secrets` so it does not need to be passed. But if you want to authenticate against another private
|
|
repository, you have to use a secret named `GIT_AUTH_TOKEN` to be able to authenticate against it with buildx:
|
|
|
|
```yaml
|
|
-
|
|
name: Build and push
|
|
id: docker_build
|
|
uses: docker/build-push-action@v2
|
|
with:
|
|
push: true
|
|
tags: user/app:latest
|
|
secrets: |
|
|
GIT_AUTH_TOKEN=${{ secrets.MYTOKEN }}
|
|
```
|
|
|
|
> :warning: Subdir for Git context is not yet supported ([moby/buildkit#1684](https://github.com/moby/buildkit/issues/1684))
|
|
> but you can use the [path context](#path-context) in the meantime.
|
|
|
|
> More info: https://docs.docker.com/engine/reference/commandline/build/#git-repositories
|
|
|
|
### Path context
|
|
|
|
You can also use the `PATH` context alongside the [`actions/checkout`](https://github.com/actions/checkout/) action.
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
branches: master
|
|
|
|

|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Checkout
|
|

|
|
-
|

|
|
uses: docker/setup-qemu-action@v1
|
|

|
|

|
|

|
|
platforms: linux/amd64,linux/arm64,linux/386
|

```
|
|

## Advanced usage
|
|
|
|
### Push to multi-registries
|
|
|
|
The following workflow will connect you to [DockerHub](https://github.com/docker/login-action#dockerhub)
|
|
and [GitHub Container Registry](https://github.com/docker/login-action#github-container-registry) and push the
|
|
image to these registries.

|
|
```
|
|
</details>
|
|
|
|
### Local registry
|
|
|
|
For testing purposes you may need to create a [local registry](https://hub.docker.com/_/registry) to push images into:
|
|
|
|
<details>
|
|
<summary><b>Show workflow</b></summary>
|
|
|
|
```yaml
|
|
name: ci

|

|
|

|

|
|
uses: docker/build-push-action@v2
|
|

|
|
push: true
|
|
tags: localhost:5000/name/app:latest
|
|
-
|
|
name: Inspect
|
|
run: |
|
|
docker buildx imagetools inspect localhost:5000/name/app:latest
|
|
```
|
|
</details>
|
|
|
|
### 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:
|
|
|
|
<details>
|
|
<summary><b>Show workflow</b></summary>
|

|
|
-
|

|
|
-
|

|
|
uses: docker/build-push-action@v2
|
|
with:
|
|

|
|

|
|
tags: myimage:latest
|
|
-

|
|
run: |
|
|
docker image inspect myimage:latest
|
|
```
|
|
</details>
|
|
|
|
### 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:
|
|
|
|

|
|
<summary><b>Show workflow</b></summary>
|
|
|

|
|
cache-to: type=local,dest=/tmp/.buildx-cache
|
|
```
|
|
</details>
|
|
|
|
> If you want to [export layers for all stages](https://github.com/docker/buildx#--cache-tonametypetypekeyvalue),
|
|
> you have to specify `mode=max` attribute in `cache-to`.
|
|
|
|
### 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.
|
|
|
|

### Update DockerHub repo description
|
|
|
|
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)
|
|
with this action:

## Notes
|
|
|
|
### 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 }}"
|
|
GIT_AUTH_TOKEN=abcdefghi,jklmno=0123456789
|
|
"MYSECRET=aaaaaaaa
|
|
bbbbbbb
|
|
ccccccccc"
|
|
FOO=bar
|
|
"EMPTYLINE=aaaa
|
|
|
|
bbbb
|
|
ccc"
|
|
```
|
|
|
|
| Key | Value |
|
|
|--------------------|--------------------------------------------------|
|
|
| `MYSECRET` | `***********************` |
|
|
| `GIT_AUTH_TOKEN` | `abcdefghi,jklmno=0123456789` |
|
|
| `MYSECRET` | `aaaaaaaa\nbbbbbbb\nccccccccc` |
|
|
| `FOO` | `bar` |
|
|
| `EMPTYLINE` | `aaaa\n\nbbbb\nccc` |
|
|
|
|
> Note: all quote signs need to be doubled for escaping.

## Troubleshooting
|
|
|
|
See [TROUBLESHOOTING.md](TROUBLESHOOTING.md)
|
|
|
|
## 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: "/"
|
|
schedule:
|
|
interval: "daily"
|
|
```
|
|
|
|
## Limitation
|
|
|
|
This action is only available for Linux [virtual environments](https://help.github.com/en/articles/virtual-environments-for-github-actions#supported-virtual-environments-and-hardware-resources).
