How to use docker build in next step of github actions after build step
问题
以下是我使用的GHA工作流程YAML文件示例。当前，我正在构建并推送Docker镜像到存储库。在接下来的步骤中，我会在Docker镜像上运行pytest。但在下一步中，它必须拉取上一步构建的镜像才能运行pytest。是否有办法可以在不从存储库拉取Docker镜像的情况下运行pytest以节省时间。
- name: Build
uses: docker/build-push-action@v4
with:
context: .
push: true
tags: my_registry:${{ github.run_number }}
cache-from: |
type=registry,ref=my_registry:cache
cache-to: |
type=registry,ref=my_registry:cache,mode=max
- name: Pytest
run: docker run my_registry:${{ github.run_number }} pytest
(Note: The code section is not translated as per your request.)

following is the example GHA workflow yaml file I'm using. Currently I'm building an pushing docker image to artifact registry. And in the next step I run pytest on the docker image. But for next step it has to pull image which was build in the last step to run pytest. Is there any way I can run pytest without pulling the docker image from registry to save time.
- name: Build
uses: docker/build-push-action@v4
with:
context: .
push: true
tags: my_registry:${{ github.run_number }}
cache-from: |
type=registry,ref=my_registry:cache
cache-to: |
type=registry,ref=my_registry:cache,mode=max
- name: Pytest
run: docker run my_registry:${{ github.run_number }} pytest

请看操作示例，了解如何在作业之间共享Docker镜像。
该操作提供了一个outputs参数：
输出目标列表（格式：
type=local,dest=path）。注：目前不支持多个
outputs。
您可以使用它将您的镜像输出到一个tar文件，然后在下一步中加载它。
示例：
- name: 构建
uses: docker/build-push-action@v4
with:
context: .
push: true
tags: my_registry:${{ github.run_number }}
cache-from: |
type=registry,ref=my_registry:cache
cache-to: |
type=registry,ref=my_registry:cache,mode=max
outputs: type=docker,dest=./myimage.tar
- name: Pytest
run: |
docker load --input ./myimage.tar
docker run my_registry:${{ github.run_number }} pytest
英文:
Have a look at the actions's example on how to share a docker image between jobs.
The action offers an outputs¹ argument:
> List of output destinations (format: type=local,dest=path).
>
> ¹ multiple outputs are not yet supported
You can use it to output your image to a tar file which you can load in the next step.
Example:
- name: Build
uses: docker/build-push-action@v4
with:
context: .
push: true
tags: my_registry:${{ github.run_number }}
cache-from: |
type=registry,ref=my_registry:cache
cache-to: |
type=registry,ref=my_registry:cache,mode=max
outputs: type=docker,dest=./myimage.tar
- name: Pytest
run: |
docker load --input ./myimage.tar
docker run my_registry:${{ github.run_number }} pytest
