# Upgrade notes
## v1 to v2
* Input `path` is now called `context` for consistency with other Docker build tools
* `path` defaults to current git repository so checkout action is not required in a workflow
* Rename `dockerfile` input to `file` for consistency with other Docker build tools
* Rename `always_pull` input to `pull` for consistency with other Docker build tools
* Add `builder` input to be able to choose a builder instance through our [setup-buildx action](https://github.com/docker/setup-buildx-action)
* Add `platforms` input to support multi-platform builds
* Add `allow` input
* Add `load` input
* Add `outputs` input
* Add `cache-from` input (`cache_froms` removed)
* Add `cache-to` input
* Rename `build_args` input to `build-args` for consistency with other Docker build tools
* Add `secrets` input
* Review `tags` input
* Remove `repository` input. See [Simple workflow](#simple-workflow) for migration
* Remove `username`, `password` and `registry` inputs. Login support moved to [docker/login-action](https://github.com/docker/login-action) repo
* Remove `tag_with_sha`, `tag_with_ref`, `add_git_labels` inputs. See [Tags with ref and Git labels](#tags-with-ref-and-git-labels) for migration
* Handle Git context
* Add `digest` output
### Simple workflow
```yaml
# v1
steps:
-
name: Checkout
uses: actions/checkout@v2
-
name: Build and push Docker images
uses: docker/build-push-action@v1
with:
username: ${{ secrets.DOCKER_USERNAME }}
password: ${{ secrets.DOCKER_PASSWORD }}
repository: myorg/myrepository
always_pull: true
build_args: arg1=value1,arg2=value2
cache_froms: myorg/myrepository:latest
tags: latest
```
```yaml
# v2
steps:
-
name: Checkout
uses: actions/checkout@v2
-

uses: docker/setup-buildx-action@v1
-
name: Login to DockerHub
uses: docker/login-action@v1
with:

-
name: Build and push
uses: docker/build-push-action@v2
with:
