The following will build the root Dockerfile, tag the image as `myorg/myrepository:latest`, log in to Docker Hub using GitHub secrets, and push the image to the Docker Hub repository `myorg/myrepository`:
```yaml
uses: docker/build-push-action@v1
with:
username: ${{ secrets.DOCKER_USERNAME }}
password: ${{ secrets.DOCKER_PASSWORD }}
repository: myorg/myrepository
tags: latest
steps:
- name: Checkout code
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
tags: latest
```
The following will build the root Dockerfile, tag the image with the git reference and SHA as described above, log in to Docker Hub using GitHub secrets, and push the image to the Docker Hub repository `myorg/myrepository`:
```yaml
uses: docker/build-push-action@v1
with:
username: ${{ secrets.DOCKER_USERNAME }}
password: ${{ secrets.DOCKER_PASSWORD }}
repository: myorg/myrepository
tag_with_ref: true
tag_with_sha: true
steps:
- name: Checkout code
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
tag_with_ref: true
tag_with_sha: true
```
The following will only push the image when the event that kicked off the workflow was a push of a git tag:
```yaml
uses: docker/build-push-action@v1
with:
username: ${{ secrets.DOCKER_USERNAME }}
password: ${{ secrets.DOCKER_PASSWORD }}
repository: myorg/myrepository
tag_with_ref: true
push: ${{ startsWith(github.ref, 'refs/tags/') }}
steps:
- name: Checkout code
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
tag_with_ref: true
push: ${{ startsWith(github.ref, 'refs/tags/') }}
```
The following builds the `mytarget` stage and pushes that:
```yaml
uses: docker/build-push-action@v1
with:
username: ${{ secrets.DOCKER_USERNAME }}
password: ${{ secrets.DOCKER_PASSWORD }}
repository: myorg/myrepository
tag_with_ref: true
target: mytarget
steps:
- name: Checkout code
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
tag_with_ref: true
target: mytarget
```
The following will build the root Dockerfile, tag the image as `myorg/myrepository:latest`, log in to Google Container Registry using GitHub secrets (where `DOCKER_PASSWORD` is a [JSON key](https://cloud.google.com/container-registry/docs/advanced-authentication#json-key)), and push the image to the GCR repository `myorg/myrepository`:
```yaml
uses: docker/build-push-action@v1
with:
username: _json_key
password: ${{ secrets.DOCKER_PASSWORD }}
registry: gcr.io
repository: myorg/myrepository
tags: latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Build and push Docker images
uses: docker/build-push-action@v1
with:
username: _json_key
password: ${{ secrets.DOCKER_PASSWORD }}
registry: gcr.io
repository: myorg/myrepository
tags: latest
```
